If the tubes seem(weld line) on the female tube is not centered in the tube then the end for end flip you do with the male tube to mark it won't work. You will end up with a diagonal line. Also I find that instead of a cutting wheel to make the groove wider, a worn grinding wheel with the thicker radius on it works well. Over all a good video though.

Good tip! Save yourself some extra work and buy seamless tube. I know it costs more but time is money!

awsome tip!

how would you weld 2 end plates on a square tubing ? a fillet weld would be used but how would you clamp for welding ?? would you only use the weight of the tube as a clamping force ? then just tack weld , and then proceede to do the all around weld ?

@1970chevelle396 ..Yes, they sell that for trailer hitches and receivers...called skived or 'no-flash'..

nice trick. If it wasnt critical, I would do that. If it was, I would use a die grinder and remove the burr from the female piece. I am sure this will save me time sometime, thanks.

Great tip for a structure that isnt critical for human life ir safety! Perfect for making lawn furniture, tables, benches etc.... That little groove will not fail or hurt anybody. Would i do that for a suspension system on a vehicle? Probably not. Its good enough for everything else. Also, you only have to make the groove as long as the "female" piece length. Great tip!

Good tip, though I'm not sure I entirely agree with it. I think the best way may have just been to hammer the inner tube in nice and secure before welding. Now a stress riser has been added to that piece of metal and given it a place for cracks to start, especially since the wall of the tube is thinner there.

Have you seen any problems arising from performing this type of preparation? What kind of load was this particular piece going to see?

@jvsee12345 Most of what they sell is made of Chinese lead, though. I wouldn't trust them. ;)

Thanks for the tip! It is just in time!
