I have a project that requires a 4" tube to telescope over a 3 1/2" tube. I cut a 3/4" slice of the large tube off and filed the weld seam away. But it is still a skootch ( technical term) too small to slide down the 3 1/2" tube. The side walls of the large tube are bent in a bit and interfere. Once the height is set there will be no more adjustments. But I still want a nice slip fit.
Any suggestions for how to make this work? I am thinking full bush league here and using an angle grinder with a sanding disc to grind away the small tube a wee bit, Then use a belt sander to finish the job and smooth out any high and low spots.
I had also considered using one of the broaching methods to broach out the inside of the large tube a bit. The small tube will be about 4 feet long and the large tube about 3 feet.
What have you used to accomplish this? If you have not done this what ideas do you have that are affordable and not overly time consuming? I have several months before the job needs completion- a rarity in my experience. Usually the parts are needed tomorrow.
Cheers.
