Shay rebuild - nachoman - 01-28-2009 This one is especially for Dave harris and Ray M ![]() I hope this posting stays, because last night there were two things i thought I posted only to come back a few minutes and learn they werent there ![]() Re: Shay rebuild - ray_m - 01-28-2009 Nice job on the frame Kevin. ![]() I need to build one like that once I find a 2 cylinder Shay motor. I picked up a pair of PFM HOn3 shay trucks at a show in Phoenix for $10. Re: Shay rebuild - nachoman - 01-28-2009 Ray - the Keystone locomotive works shay has a 2-cylinder motor, and I think they sell the cylinders as a separate detail part: <!-- m --><a class="postlink" href="http://www.walthers.com/exec/productinfo/395-29">http://www.walthers.com/exec/productinfo/395-29</a><!-- m --> Re: Shay rebuild - ray_m - 01-28-2009 Thanks for the link Kevin. That's exactly what I need. ![]() Re: Shay rebuild - nachoman - 01-28-2009 I have the frame completed to a point where I can test fit everything together. So far, so good ![]() ![]() Re: Shay rebuild - doctorwayne - 01-29-2009 Nice job on the frame, Kevin. With workmanship like that, you should end up with a good-lookin' and smooth-runnin' loco. ![]() ![]() I built both a two-truck and a three-truck shay for a hobby shop when the MDC models were first released. While they did take a bit of tinkering, they ended up running very nicely, even with the open-frame motors. One of the main reasons for poor performance was either excess play or not enough clearance in the driveshaft system. The male shafts that fit inside the square tubing were too long, limiting the ability of the trucks to pivot. Also, the drive gears liked to "walk" on their shafts,causing misalignment with the gear teeth on the wheels. There were some other issues, too, although my memory doesn't work too well back that far. ![]() Wayne Re: Shay rebuild - Dave Harris sctchbld - 02-02-2009 nachoman Wrote:This one is especially for Dave harris and Ray M Nice work Nacho, how did you know Shays are my favorite . That frame looks SUPER !! If you are interested I could dig out a MDC that I rebuilt into a Quasi "West coaster " by scratching a cab & reworking the frame extensively. It's around here somewhere & in pieces now because I started to repower it & then ended up moving & sticking the dissasembled engine in a box. Re: Shay rebuild - nachoman - 02-08-2009 A quick update on where I am on this project- I have built and installed truss rods on the fireman's side. I don't think I can figure out a way to make the truss rods fit on the engineer's side because they would interfere with the cylinder assembly and driveline. The truss rod would not be that visible on that side, anyway, and to install it would require a re-design of the driveline that would probably be more trouble than it is worth. I've also been working on the end beams adapting them to use HOn3 Kadee couplers and adding wood grain detail. I have ordered new driveshafts, so hopefully I will be able to test out the mechanicals soon. Re: Shay rebuild - Bigsteel - 02-08-2009 man,what you can do with brass and solder amazes me,i never could get a hang of soldering.so many times i burnt myself so i went to plastic and glue,now i just glue fingers together ![]() ![]() Re: Shay rebuild - Dave Harris sctchbld - 02-10-2009 Nachoman, Your Shay just keeps looking better-N-better. As you all know --I LOVE the look of Solder-N-Brass AND YOURS LOOKS GREAT! Re: Shay rebuild - nachoman - 02-10-2009 Thanks for the compliments, guys. next up is to make a firebox. I am on the lookout for a good prototype photos that will help me out here. Re: Shay rebuild - tetters - 02-10-2009 Hi Kevin! How's the layout coming? Your Shay build is looking pretty solid. I always love watching this stuff come together. Re: Shay rebuild - eightyeightfan1 - 02-10-2009 I have trouble soldering two pieces of wire together, you guys are soldering as if you're plasma welding. Kudos to all! Re: Shay rebuild - nachoman - 02-11-2009 Tetters, my general layout thread can be found here: <!-- l --><a class="postlink-local" href="http://www.the-gauge.net/forum/viewtopic.php?f=46&t=542">viewtopic.php?f=46&t=542</a><!-- l --> I haven't gotten much progress done lately, but I am slowly getting there! Re: Shay rebuild - nkp_174 - 02-19-2009 Don't forget that a real firebox would interfere with the drive shafts. That why MDC just include a 2D firebox. I think that you can improve mightily on theirs...but I don't have any helpful pictures to post. |
