I need to be able to slide (tight fit ok, even preferred) 1.5" OD square tubing into another tubing. I was thinking 1.75, 1/8" wall.
However somebody has suggestedt he seem will get in the way. Is thsi not feasible?
Aparently this is not an easy size to find. I only need a little (e.g.30-32") which will be cut into 6 small bits anyway. Any suggestions?
 
i've done just what your describing for the jack mounts on my sleeper cab. I used 1.5" .120 square slipped inside 1.75" .120 I only had to slip ~4" inside I was able to use a flat file and smooth the seam down. I did have to smooth the 1.5" tube on the outside to make it more of a slip fit. I used my flap disk to lightly sand it down on the sides..

I also used the same tube and inserts on my work bench. I welded a 1/2" nut onside one corner and made a T-bolt to tighten the insert. I then put my bench grinder on one insert. As well as a few other 'holder' type tools. I can then flip my grinder upside down on the side to tuck it out of the way..

I was luckily able to find some scrap locally, but there is also a website online and ebay that sells almost any size tube in any length. Might scan ebay for that size..
 
Like he said, you will have to either file the seam down or file a groove into the smaller tubing. Since your pieces are so short, that will be easy. You can also look for seamless square tubing...
(p.s., square tubing doesn't have an OD.) :flipoff2:
 
Well it looks like Fishel Steel has it here.
He reccomended bring by a peice of my 1.5 OD just to be sure. Pointed out that often 11 ga (.120) and 1/8" (.125) are used interchangeably... although here the .005 could be a noticible difference.
It this case, tight fit = better. Actually having to pound it in would be even better.

I've changed my mind on how I want to mount the rock sliders I made. Originally I made 'em w/ mounting plates, was going to drill holes, and bolt to frame. However that's 48 holes to drill, 24 of which are under the vehicle. Ick.
Instead, I'm going to weld the 1.75 tube to the brackets, and just weld those to the frame. The sliders, 1.5, will slide into these 1.75" posts and bolt in... so I can remove 'em later if need be, and still effectively provide 1/4" wall mounts for them.
