Rollout Wheel (Welding Positioner)

Looks very nice! Better than professional.
Wondering why you ground off a lot of your welding? I mean, a stack of dimes is a pretty sight, don't you think?

From your earlier posts I recall the little mouse ear holes. I can see they wouldn't be all that attractive.

Although I probably wouldn't bother with a lot of grinding on a fixture, (unless it was butt ugly,) I can say what you have shown looks really well done. Attention to detail is quite apparent.

I assure you, my aggressive stitch welds over the holes were butt ugly.

So the rollout wheel is on 2” O.D. square tubing like a trailer.

The pictures below show a length of 1/4” wall, 2” I.D. square tubing that is mitered for a sleeve. I am going to weld this up now.

The rollout wheel slips into this 2” I.D. square tubing, & the sleeve goes on the main mast of my welding fixture stand.

Here are the parts getting their first coat of spray paint:

I got sidetracked for about 2 weeks going over the used lathe chuck that I bought.

I did a very thorough cleaning on the chuck, & I had to bore out the chuck center hole from 2.167” to 2.55” in order for the chuck to fit over the hub on the positioner.

Here are 2 pictures taken after I refinished the chuck body, cleaned all the parts, and applied Evapo-Rust & oil.

Evapo-Rust is an amazing product!

Here is the Bison 8” 3-jaw scroll chuck being reassembled. All my cleaning work paid off, & the action is very smooth.

When I tried to mount the chuck on to the rollout wheel, the holes did not line up. I had to drill out the holes up to 1/2” diameter.

I got very lucky that the chuck jaws clear the dust cap on the hub, although spacers would have fixed that issue.

The chuck looks really small on the positioner.

Here are pictures from the test fitting. I still need to break it down to touch up the paint.

Here are some pictures of the “rollout wheel arm” on the fixture stand.

I still have to build a base that bolts the fixture stand to the floor.
