Technology is great

Post by John_S » Fri Jul 14, 2017 7:29 pm

A while back I brought all my rolling stock home to work on and they've been sitting on the floor in the garage. Pain in the butt! I decided I needed a couple roll-around stands for them so I sat down and designed a stand in CAD. I work for Ryerson and we have three tube lasers at our facility so I thought, "I could make quick work of all this tubing by designing the parts to be cut on the laser."

They're made from 1x1x065wall tubing. I designed each part with tabs and slots so they all basically "snap" together. This means that when I go to weld them up everything will already be square and aligned. It also means that I don't have to touch my bandsaw.

Here's the general design:

Here's some of the parts converted to 3d parts in Solidworks:

Spacer between rails, with material cut out to allow room for wheel flanges

And here's the cut parts right off the tube laser:

Here's a video of the 9' long rail tubes being cut. It's hard to get good video because of the UV shield around the head of the laser.

Over the next couple weekends I'll get these welded up. I'll post more as I go along.

That takes all the challenge out of it. Besides, why would you want to deprive yourself of listening to the screeching noises coming from the band saw as it cuts through thin tubing? :D

Whir, whir, whir, whir, sccreeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee, whir, whir, whir, clunk!

I do still have to cut up a bunch of 1/4x3 flat bar to make the bases that the legs and casters attach to, so I have that to look forward to!

That is amazing John. Does it wipe your butt too?

Very nice! Is 1x1 going to be rigid enough for a loco, or is it for rolling stock only?

That shouldn't screech.

BTW, here is a pic of the erecting stand I built for my shop. It's eight feet long, rolls on eight inch casters with roller bearings and can support 2000 pounds. Needless to say, it wasn't built with thin wall tubing. :D

I like the concept of using lighter weight material. Looks nice!

Rolling stock only, nothing over 150lbs.

A little work tonight getting started putting the first of two together. Building it upside down on the shop floor.

Only downside to doing this on the floor is the awkward welding position with the TIG.

That is great. Jon Eric Nystrom did a steam locomotive in LS&OR magazine a while back like that. Frame parts on one sheet, cab parts on another of thinner material. As I recall, his tabs came through such that he used TIG without filler rod.

Finished one of two stands tonight. It turned out nice. Lightweight, very strong, and rolls around smooth as butter.

Fun project, and I still have one more to go!
