I got my aluminum Friday night and yesterday I pulled out my hacksaw to make it a barrel vise bushing.
A Starret bi-metal coarse tooth blade (24 tpi I think) makes quick work of aluminum.
I used my calipers to mark 3" on the tube, then wrapped next to the scribe line with painter's tape to make sure the cut line looked square. That gave me a super visible reference to saw to. Of course push down on the cut stroke and no pressure on the return to avoid clogging or dulling the blade. After cutting to length, I used a flat file and a round file to smooth and chamfer the cut edges.
Slitting the side was similarly easy, just long smooth strokes with the hacksaw, a bit of inside clean up with the round file and a few strokes of the flat file on the exterior.
The proof in the pudding is that the aluminum did not spring enough to cause a tight fit on the barrel, it's a loose fit but only by a few 0.001"s like the 1.250" i.d. and 1.240" o.d. would suggest. The saw kerf seems to be enough to squeeze for a tight fit on the barrel. If the tube o.d. is close to the 1.750" size and the barrel vice i.d. is also, everything should be great but I haven't measured that yet. If there is any discrepancy, I hope to solve it with alumanized duct tape.
Later today I plan to measure my chassis for my linear bearing mount.
