      Hi Rob:

       

      Good to hear from you, sorry it took so long to post again, the cold really got bad and I had substantial pain in my teeth from sinus pressure. It finally began subsiding
      Thursday night...

      Also, the curved single sided tandem turnout we're building this week was tougher than I thought it would be. Turned out great in the long run, but definitely had a
      learning curve. We have to build one more, but now I know how so it should go much smoother.

      The outdoor loop is remaining single track as plans are now, however, there will be extensive passing, staging, and storage tracks on the outdoor railroad extension. There is
      also plenty of time for plans to change.

      I appreciate the offer of the camera body, and that is a pretty nice camera from its era, but it is also about the same as the one I just had fail on me, after 12 years or so
      it is time to upgrade. I have been saving my carburetor and distributor money for a while and have enough to get a nice semi pro or pro camera with lens package. My
      problem is just time.

      With April starting tomorrow, there is still a lot to do around the railroad. So my posts might get shorter or have a little less exposition.

      This post will be to catch up on some pictures I've taken related to things in other posts. First is a report on the rust and corrosion preventative Fluid Film.

      In the picture is the turnout with the Fluid Film sprayed on it twice during November. After sitting all winter, I walked up and it looked like some surface rust had
      formed, but not too much. I figured a scouring pad would make it nice, however, I just wiped it with a rag, and it looked great.



      I purchased this can to test the product. It is available in larger bottles and buckets that could be used to fill a spray car. You can clearly see in
      the photo the difference in corrosion where it wasn't applied.



      Next is just a picture I forgot to post. Somewhere in all the last posts, are a couple about the diamond crossovers. In them, I mentioned
      the angled pieces I make so that we can form the diamond. This is a closeup that clearly details how we use them.



      Next up are some pictures of the tie making machine. This cool contraption was built by a fellow named Jim who used to do a lot of the infrastructure
      work on the railroad, and was instrumental in its original construction.



      This is a picture of the spindle, which uses two 3mm(.118") blades to cut the slots. This gives a nice press fit on the rails. A sample strip of tie
      stock is in the picture. In use many strips would be stacked and pushed through at the same time. The table rides in slides that can be seen
      in another photo coming up.

      It is hard to tell, but on the right side of the tray, a scallop is cut into the stop surface to the right of the blades. This scallop, allows the ties a
      small amount of variability in length.



      When the tray is pulled back away from the blades after a cut, you use the pusher to move a fresh stack of strips into position for a cut. Here
      it is easier to see the scallop. Also, the tray would normally be full of much longer strips, but I didn't have any ripped to length while taking
      these photos.



      From the rear of the machine you can see the exit chute that cut ties slide down into a bucket or box. You can also see the slides that allow
      the table to freely move across the blades. A lid pushes down with foam to keep the tie strips in place during cutting. Something has gone
      wrong with the spindle during the last use. The cut off blade is now wobbling around. I must remove the spindle and repair whatever is wrong
      soon.



      We must go work on the railroad some more. It is a sunny and warm day here in Portland, and I am feeling much better.

      Next posts will be track work again. I have been editing photos to tell the story of how and why we tore out the middle loop and
      are starting over, and how the new approach is paying off. I will try to post more often this week. Pictures are done...just need time.

      Karl, I hope you don't mind if I post a link to this thread on the major UK-based garden railway website, gscalecentral.com.  A few of the posters here are also members there.  It might be a good idea for Dan Pantages, David Leech or Peter Szolga to post a link to the Gauge 1 NL&J - I'm totally positive that the many Gauge 1-ers in UK and Yoorup would be fascinated to see what goes into making Stavers the enormous success it has been over the years.  Dan and a few others know that we come over to Portland and places South at least once a year, but our visit has never managed to coincide with a meet, which is, for me, a real tragedy.

       

      Epovah, next year, with the big show happening in PDX, we'll manage to coincide our home-trip with a visit!

       

      Best from over near, near Belgium.

      Hi Tac:

       

      Feel free to link to these posts. Larry is not paying me to do this, it was my bad idea to spend what few extra minutes I have posting online.

      That said, I think Stavers is one of the coolest places ever, and I don't think Larry or the railroad get the attention they deserve...at least from the
      many that have never been here. But how is anyone to know whats going on here if we don't talk about it once in awhile. Also, it just
      seems to me there used to be a greater quantity of interesting stuff to read on the live steam forums, and I thought this would be an interesting
      story to tell the community. 

      Its not that often a large railroad like this gets torn up and rebuilt with interesting techniques.

      I spent the morning editing the last pictures needed before I can start posting about track building again. I hope to have time in the morning to get a
      post up.

       

      Happy steaming

      Hello everyone:

      Feeling much better these days, and we are extremely busy at Stavers. Jenn and I have removed about 50 more feet of mainline that we built this winter, including the
      west yard throat and salvaged curved crossover from earlier posts. After designing a couple different yard variants, it became apparent to Larry and I that trying to
      follow the old alignment was creating a very tight yard entrance. Also, the yard throat I had installed in December was located on the adjacent passing track of the
      mainline, and because of the alignment, any moving of trains or cars into and around that side of the yard, would mean the passing track would have to be used, creating
      a traffic problem. So the yard throat needs enough track so you can build a train in the yards without moving on to the passing track of the mainline.

      If we rebuild the table top to accommodate a different angle exiting the middle yard loop, then many possible options become available. So I redesigned the yard for
      much improved usability. The track work will be nothing like what was in this loop before...however, I start telling that story after this post.

      This post is about the yard throat on the other side of the loop, we finished this track work about two to three weeks ago, and after this post, we will be catching up
      to where we are working now on the railroad. Although that will take us back two months to the beginning of that aspect of the story.

      Here is a picture looking into the building along the mainline facing east. At the end of this stretch of track is the beginning of the  middle loop and the associated
      yards we need to build. We need a yard throat just on this side of the bridge where you enter the middle loop.



      When we first started thinking about the yard throat for the entrance to the yards when heading east, I thought I would be able to use a couple salvaged turnouts. No
      matter how I aligned the best options out of our old turnouts, the alignment wasn't going to work. So I went to Templot and designed a similar set of turnouts, took the
      printout over to the railroad and this is what it looked like...



      I didn't want an "S" curve with no lead straight, and Larry agreed, so back to the drawing board. I went back to Templot and thought of a different
      approach. This is what we ended up deciding to build.



      First step after final decision is to print out the inverse of the switches on 46# paper and Jenn can start bending rail. A #8 turnout is used on
      the passing track of the mainline, and a #7 is used on the yard. We have also decided to start making all our frogs with the new shorter
      method, so I had to modify a couple for Jenn to use during construction.

      So this shot shows how we layout the pre-bent rails and the frogs using very strong neo magnets. Jenn is getting very good at bending rail fast
      and accurately.



      We also use the laser cut gauge separators to make sure everything stays mid gauge. As usual, we will clamp straight edges where appropriate
      to keep everything aligned during welding. I couldn't find any images of the assembly all clamped up, must have been focused on work that night.



      Here is the assembly all welded up, just needs points and ties. I took this shot outside in some interesting light, generated by the low winter sun,
      just about to go below Portlands West Hills in the late afternoon. The turnout in the drawing that we're not building is because we haven't finalized
      the design going that direction...we will build that out later.



      Took the assembly inside for a test fit...like a dream, should be an easy install.



      Now Jenn has to make ties again while I move on to working on designs for the yard.



      Here Jenn is finishing up installing ties using some laser cut tools. Since Larry has a laser, I have used it to make us many helpful tools. These
      help Jenn space and align ties.



      Here Jenn is about to cut a slot in a tie by sliding the router across. If you look closely, you can spy one of the many reasons I love Jenn...
      She has been pre-disastered in a hydraulic wood splitting incident. Since we own a machine shop and work with tools, she has already
      learned an invaluable lesson about the unforgiveness of machines.



      Here is a tie after cutting and ready for installation. We don't try to make a tight press fit, there just isn't enough precision and it would result in
      many lost hours. Instead we route them slightly over size and glue them in place.



      And finally, finished and installed. Looking to the east and the entrance to what will be a large storage and steam up area.



      Looking back to the west...



      We are about 1/3 of the way through re-sheeting the middle yard loop for the increased size of the yard...now we must go finish the next third
      so we can start building the yard. Last weekend in April is approaching faster than my GTO...

      Happy steaming

      Hello to those who are still paying any attention. I have a few minutes before heading to work and thought I would post a few pictures and
      get started explaining why we tore out 75 or more feet of railroad we just finished building.

      Jenn and I are very busy trying to get everything done in time for the steam up in a few weeks. Right now, we are building a connected
      series of four curved turnouts that are part of a network 7 turnouts that make up that section of the new yards. Although we can print up to
      10 foot lengths at 2 feet wide, our welding table is only 8 feet long, so I fit as many of the turnouts as we can to build at once on the table.

      Finally got a new to me camera. Nikon D7200 with Nikon 40mm Macro lens and a nice Nikon 18-140mm. It takes stunning photos of my cat so far...
      The macro lens is excellent for photos of machined tiny parts, and the 1080P/60 frames will allow for slow motion analysis of machine operations on my cnc
      lathes and mills. Something I've been doing for years for process improvement and/or diagnosis of operational problems. Anyway, hopefully some
      more consistent photos and better light sensitivity.

      Back to trains...While Jenn and I were building the track work in December, Larry was getting good at designing turnouts in Templot. Our problem was that
      to be able to design turnouts for curves, we would have to know the exact radius of the existing track so we could fit it to that track after building. Larry
      was experimenting using chord length measurements to find the radius at different points on the track. We even purchased a special dial indicator that takes
      a depth reading and automatically calculates the radius. Problem is that it is so sensitive that it is very difficult to take consistent readings. It is designed for
      smaller radii. I think if we build a fixture for it that uses the track for stability we'd get good results, but it turns out we could get satisfactory results going
      back to basics.

      So the real issue, is that in the double track we had already built, including the curved crossover and yard throat, we found that the radius varies wildly in
      any given length of just a few feet. In order to design a yard in Templot encompassing all of the area of the yard loop, and know the turnouts would align
      correctly, we would have to have a very accurate representation of the entire curve around the yard to use in Templot.

      So I started measuring the curve back in January, and this is how I did it. A brand new, precision Starret 18" ruler, and a precision ground pin set were used
      to find the chord height. Made a mark at each measurement, and then shifted the ruler 4.5", and recorded another measurement...113 or so times, it took hours.



      We then needed to build the Templot track pieces one 4.5" section at a time to recreate the existing curve. But first I needed to load a spreadsheet cell
      or two with measurement data and some equations to calculate the radii and swing angles so that the short sections of curve could be created.

      This picture is a subset of all the measurements so you can get the idea...this is actually an updated spreadsheet to the first one we did. We built
      the curve using the original calculations for the arc angle(swing angle in Templot), however, it didn't fit our cad overlay of the building posts and
      such, so I knew something was wrong. It occurred to me that with the changing radii every few inches, there was know way to know if I was
      calculating the arc angle based on the beginning or end radius of the curve, so I averaged the before and after measurement in the second
      to last column, and used this to generate the curve, it then fit remarkably well.



      At this point the Templot representation of the curve showed us exactly how bad the situation turned out. Each
      individual curved piece has a cross hair located at the radius center point. And it generates a sort of scatter plot
      that shows how many radii there really are in an obvious way. To design track work and a yard to fit this would
      negate the new found precision in which we have built up through the yard throat.



      So I decided it might be useful to graph some of the data and see if we could figure a way to average the curve, or break it up into a few sections.
      This graph is of the averaged vs. individual calculated swing angles. We just wanted to see how the average was smoothing the curves. In the graph,
      blue is the averaged, and you can clearly see that the smoothing of some spikes that most likely caused the first curve to be not quite right.



      The next is a graph of the individual radii. So even though the curve looked nice in place, Larry just couldn't
      bring himself to build this large new yard and not be able to use Templot to lay it out first. So...tear it all out said Larry, and the day after the
      March first Tuesday operations session, out it all came.



      At this point, we now have to design a replacement curve to fit the area. Larry wanted to try to hold it to a maximum of three separate radius, with
      proper transition curves between them. I was able to succeed, and this is the replacement curve. You can see only the three radii near the center.
      The other two at the top of the curve are for the transition curve from the yard throat side and were already accounted for in construction.



      And here the curves are overlaid, with the original in blue and the new curve in red. Now I can start work designing the yards and we will
      rebuild everything at once which will then be the same as our Templot representation of the railroad.



      So we printed out this curve on lightweight paper to make sure it would fit. Sure enough, it fit perfect, aligning at both ends...however, it takes
      quite a bit of smoothing and slight shifting of the paper templates to make sure they are laid down flat and wrinkle free.

      This picture show the west yard throat area. We have now torn out the curve on the other side, and the tables will be rebuilt to allow
      a better angle across the bridge and into the next curve.



      Here is where the curve ends up at the now completed East yard throat.



      And finally, an overall view of the curve laid out on the bench work. We are about half way through rebuilding the bench. I started by folding the
      paper back past the first transition curve from the east, then rebuilt the top of the bench up to the transition in the bottom of the next picture.
      Then we rolled the curve back out and marked the locations of the transition curve start and end points on the new surface. This gave me the
      points I need to lay out the printout of the entire new yard all at once and have it align. We then removed the printed out paper curve and tore
      the top off the rest of the bench work.



      We must go to work now, many turnouts to build. Next installment, the yards I came up with and perhaps the tandem turnout build pictures.

      Happy steaming

      Reading back a bit, what glue do you use for the rails in the ties? How do you clamp the rails while the glue is setting.

       

      And I'm sure there are many people following this, so post whatever you want, don't worry about people being interested, we are!
