BIRTH OF A 3 TRUCKER

Modeling
#41

Another update,

Back at the start I said I couldn’t find a cross compound air pump, well I did find one made by AccuCraft by didn’t feel I wanted to pay their price for it so I built this one instead.

It is just made up from Styrene shapes and brass wire as you can see. Far from perfect but once painted and mounted I think it will serve the purpose.

For the low pressure air cylinder, bottom right in the finished picture, I couldn’t find anything the right diameter so turned down a CPVC 1/2 inch coupler and then mounted it in a vise and left it for a couple of days. This treatment caused it to hold the elliptical shape until I got it glued down.

That thing hanging off the side is the air intake/filter

Quite nice. Don’t you just love the feeling of building a part yourself? Especially so when it turns out great.

#43

Airpu,ps are great fun aren’t they? Tedious to build but they look SOOOOOOO Darn GOOD! when painted and mounted!

#44

Nice modelling.

#45

Very impressive.

#46

Looks great. What glue do you use to put the air pumps etc… together. I have been wanting to try making small parts like that. Im assuming a faster drying glue?

#47

That’s a really good looking air pump you’ve got there Rick.

Appreciate the comments.

Bruce, Yea, I like building parts and every once in a while one turns out OK.

Shawn,

For gluing Styrene, ABS, Lucite, etc I use Ambroid Pro Weld or Plastruct Bondene. They are actually a welder not a glue as they melt the surface of the pieces for a bond. They are water thin and I use a small paint brush to control the application. They are very quick grab and will hold a pretty good load even while they are curing. You can do the same thing with MEK which can be bought in larger quantities for less money. But, these glues are volatile and I find the smaller bottles work better for me.

My other glues of choice, although no one asked, are; 2 part 5 min epoxy, plastic epoxy, E6000, Tite Bond III, JB Weld and of course Super Glue. I used to buy the real expensive Super Glues and end up wasting most of the bottle because it dried up. Then I read somewhere of just using the cheap stuff in the small tubes from Wal-Mart because it was just as good. I have been using the cheap stuff for the last few years and find that it works perfectly fine for me. If a partial tube dries up it is no great loss.

More pictures to come soon

Got a little more done.

The dynamo also is a little different than the one commonly seen on the Shay (especially the Bachmann version) so it had to be built as well. A fella at Fish Camp was kind enough to e-mail me pictures of the air pump, dynamo, and steam water pump so I had some good references. The dynamo is a Pyle-National brand but I am not sure which model. Again the modeled piece is close but not a perfect reproduction.

This gives a good idea of the size of the finished piece. The black area on the left end was cut from the Bachmann version and modified for use here, saved a little scratching.

The #15’s dynamo was mounted out on the side of the smoke box not up on the boiler top near the cab. This may have been done to get that annoying whine produced by these contraptions away from the crews ears. To achieve a solid mount I drilled holes in the smoke box and glued some blocking inside the boiler. I then used some aluminum welding rod as the support arms. The arms were covered with Styrene channel and straps added up the smoke box side.

A couple pictures of the completed mounting. Straight pins were used as anchor bolts to mount the dynamo to the arms this is so it can be removed for painting, piping, etc.

All I can say is wow!!! Really tempted to rework my 3 trucker like this, I would be happy if it came out 1/3 as nice as this one will!

#53

REally nice!!! Building the detail bits is my favorite part…I can honestly say I have never placed an order for detail parts except for brakewheels…

Yup, and quite a few are scattered from Illinois to Canada…:wink:

#55

Very nice Rick. Time well spent; this will be a beauty when done.

#56

Painted and fitted.

Now just need the weathering coats and all the piping.

It is getting close to wiring time, can’t wait to start that phase as electronics is my

favorite part :frowning:

Nice! Lov’n the stack!

Back with a little more progress.

It is getting close to completion and I am fighting the urge to hurry. Good thing I have lots of other non train things that have to be done to help slow my progress.

Anyway, today’s update.

While I had everything torn apart It was a good time to airbrush the base coat of weathering, I used Weathered Black made by Badger in their Model Flex line. It is an Acrylic that can be sprayed straight from the bottle but like most Acrylic’s it has a tendency to plug the spray nozzel (very quick drying) in the air brush if you let it sit more than a few minutes. Trying to find air brushable railroad colors now days is a real adventure. There is a lot of stuff out there but most really doesn’t work very well. But then that is just my opinion.

OK! The base platform of the Shay is back together and everything rolls in the direction it is supposed to when it is supposed to. So now we are ready to start the electronics. In my opinion the electronics are just the necessary evil that turn a locomotive from a pile of plastic and metal bits into something that has a life and presence of it’s own. Though I am Electronically challenged I would never consider building a loco up without onboard power/sound/control.

Stay tuned for the fun stuff.

Wow! I too have to chime in and say how much I like the detail parts. Great work!

#60

Wow! Just tuned back in, Rick…VERY impressive modeling! But then, that’s about par for you, right? (Grin)
