I want to make a part using 1 1/4 square tubing, or about this size.(Steel)
And I would like to have another piece of square tubing that will slide inside this tubing.
I've found at my local metal place that the smaller sizes are too loose.
I was going to put in some shims to make it work.
But can you buy square tubing 'somewhere' that is made to fit inside for applications like I need?
So, can you get this tubing and what is it called?
(The part won't be in motion.)
