Engine rotisserie stand

Post by jscarmozza » Sat Jul 07, 2018 3:44 pm

Has anyone built an engine rotisserie stand? I find it very difficult to work on the underside of my locomotive and thought this would be a good project to add to the list :) Any plans, photographs, etc... floating around out there?
Thanks, John

I have built a "rotisserie" type of construction stand for my loco as it quickly became much too heavy for me to keep turning it over to work on the bottom. Understand, that my loco is a 1" scale loco, not 1-1/2" scale. It is a fraction of the weight of the larger locos. The total weight is about 120 pounds, 1-1/2" scale loco are many times this. Perhaps my stand could be modified to work with heavier locomotives.

Here's the link to the drawings: https://supersimplex.yolasite.com/Const ... -Stand.php Scroll to the bottom of the page for the drawings. I got these drawings off the internet from Colin Abrey and modified them for my purpose.

Thanks David.
I wasn't thinking that it could be mounted on a work bench, I like it! I like the height adjustment feature too, and I see that the engine to rotisserie mount is customized for each engine, another feature I wasn't thinking of. I was going for a one size fits all mount (whatever that would be). I'll try to come up with a solution to your problem of swinging the full weight of the engine, maybe reducing spur gears or a worm screw and gear...I'll have to think about it. I knew that someone out there did this, no point reinventing the wheel; thanks again for sharing your experience and design.

As for swinging the full weight of the loco, the mount is built in such a way that you can change the pivot point relative to the center of gravity. This way, when you remove the locking pin, the loco does not try to spin! But, a worm and wheel would work as well.

With the crank, I can lift the loco right off my test track and into the air, and then turn it. Each lifting assembly can also be set on the track at a steaming bay, should you need to.

I studied your photographs, I think I see what you do with the mount adjustment to balance the engine. I have three 1" Atlantics, two projects and one up and running; each one will require its own mount as the frames, pilots and other features are all a little different. I can see that the mounts may get a little tricky. That being said, I like your design...far better and more versatile than what I had in mind. Thanks again David.

Glad you like it! The wooden beams that the buffers fit into are white oak with 4, #10 screws holding the top and bottom parts together. The holes that the buffers fit into are felted for a tight fit. This is plenty strong for my 1" loco. The wooden part is probably the part that you would make custom for each different loco. Maple would work well for this also.

Yes, the rotating part of the mounts and angle iron can be put together several different ways. Each way, re-positions the center of gravity. I had to do this twice as my locomotive got heavier as work progressed. Now that my loco is mostly finished, weight wise, it is still a little bit top heavy and when turning the loco, I always have one hand on the steam dome and the other on the locking pin pf the construction stand!
