I am going to modify a Warn winch to be used with my 3-point hitch, I am using Class III hitch tubing for part of the project so here is the question. If I am going to weld 2" OD tubing into a 2" square receiver do I need to be concerned on how deep the 2" OD is inserted before welding? My shortest Class III setup has 6" inside the tube but that of coarse would rotate around the pin not be welded firmly in place. It is a 12,000lb winch so stout is good. Why does this question seem like it should be in Penthouse forum? :)

If possible, I'd insert the 2" deep enough to weld BOTH ends - that way your outer weld won't be tempted to act as a PIVOT under heavy loading... Steve

Can't do that as the other end of the receiving tube will be needed for other 2" hitch components, clevis, etc. Would simply drilling and bolting the interior tube accomplish the same? Thanks

Maybe you could draw up a sketch of what you have in mind ... how you would like it mounted. I welded up a winch mount with trailer hitch. I'm sure we could help with options.

figure out how far you can insert 2 inch tube and drill holes in the side of the 2 1/2 inch tube, weld inner tube to outer tube filling in hole.

Agreed, plug welds would accomplish the same thing which is NOT letting the single weld point "work" - a bolt would help, but they'll still loosen and allow the inner end to move.

Another option, if you ever need to take the winch back out, might be to cut your 2" tubing on a slant, weld a 5/8" nut across the inner end, cap the outer end and drill, and run a 5/8" bolt thru the whole thing - when you tighten up that bolt, you'll WEDGE the two sections together and remove all the slop... Steve

Edit- scratch that last idea, it'd work well for mounting a vise on a bench but a winch would probably pull it out...

Sorry, maybe the purpose was of no value to this discussion. Basically I am building an extension as shown and wanted to know how far the skinny end should go into the fat end before welding. The plug welds are a great idea.

As far as you ca would be best. But it depends on your welding ability. A proper weld could simply be butt welded with nothing inside the tube and hold just fine as if it were 1-piece of tubing.
