I want to make a wood lathe tool grinding jig like the Wolverine setup. I need square tubing that has smaller square tubing ina sliding fit.
If I buy the readily available 1" x.120 and 3/4" x .120, will the 3/4" tube fit inside the 1" tube without any fettling? I'm not sure how the corners internally might interfere with the smaller tube so thought I'd ask.
As an alternative, McMaster has "nestable square tube" which can be had in 1-1/4 x .105 and 1" x .105 and they claim that you can doa ll sorts of fixturing by nesting the two sizes together - the extra 30 thou of slop would be unwelcome though if the .120" stuff fits.
