Square tubing question

[bones1]

I need a nice slide fit on some 2'' square tubing. I need to slide a 2'' piece into a 2.5'' piece with little slop.Just trying to get the wall thickness right to do this. Would a 2.5 with a 0.25 wall be what I need to take up the slack or would that be too tight?. Thanks for any info.
I see 0.12 ,0.1875 ,and 0.25 online.Unfortunately I have to get this online and can't test fit them.
After reading my post it seems like a really dumb question.

Not dumb, but I think you answered your own question. If I recall correctly 2 1/2 1/4wall tube would be 2 in id,

What I did in your situation was buy a piece of reciever stock, 2 inch slides inside perfectly. It cost a bit more but is also thicker wall I think 1/2 if I recall

Are you looking for trailer receiver square tubing? 2.5 X 2.5 X .250 is used for trailer receivers. What is the wall thickness of the 2 X 2 tubing? Only some size work. The corner radius sometimes bind.

0.1875 on the 2'' tubing.That receiver tube would be heavy and expensive but make a nicer job.Would a chart be available for this?. Order Mild Steel A36 Square Tube in Small Quantities at OnlineMetals.com

My question too. HF has standard receiver tube 18"L for $15. Item #97093-0AXH.

The square tube will have a welded seam inside unless you purchase special tubing

MrJimi.......I forgot about the inside welds

agrisupply sells a receiver that is 6" long for less than than $10, I got 3 of them, and they work great

Some good metal information. 25 Hot Rolled Steel Forms

Check out this link... Steel Square Tubing - All Metals Incoporated
What you want is .238 wall. It has all the weld flash removed inside and out.

Bingo.Thanks BigDogues.That should make a nice fit with 2'' tubing.

I read someware that they run a broach through the tube to clean up the inside weld..........Larry

I use the 2 1/2 x 1/4" wall all the time for receivers and never had a problem with the seam on the inside.

 

[bones1]

Thanks for the replies. I'll try some .238 and .250 wall and go from there.

What is called for is "slip tubing" - it does not have the welded seam inside or the rounded corners. We used it in a plant manufacturing big fertilizer applicators (did on 110' long). The purpose was to stiffen the tongue. The frame IIRC was built from 4" heavy wall tube with a center rib of 4" slip tube down the middle. A chunk of 3 1/2" heavy wall was shoved into that.

We 'liberated' enough of both to build 7 wood splitters using it for the slide.
Mine is #7.

I use 2.5" x 3/16" for the outer and 2" x 3/16" for the inner. The result is a 1/16" gap for the slip fit and consistant corner radius.

I agree with Gizmo....I also use 2 1/2 x 2 1/2 x 3/16" wall. It is good and loose, but not too loose. Works great and if it gets a little dirty, you won't have to beat it in with a pipe.
