Slicing Metal Tubing

[detailstymied]

i would like to make some clevis ends for .020" brass rod. they would attach to a piece of shaped .015" brass sheet (with acc would be fine).

i think i could drill a hole in a block of hardwood the o.d. of a piece of .5 mm brass tube, slip a piece of #76 drill rod into it to keep from collapsing, and clamp it in my panavise to hold the assemble vertical.

question is, what saw could i use with a thin enough kerf to slot the tube lengthwise about 2 mm?

thanks

Thats some cut! Both sides of the cut would only be .25 mm minus the material the blade has removed. You haven't got any room for error. I suppose you could use a very high speed with light feed (pressure) Dremmel type disc cutter one side at a time or the disc might wedge/lock. Its just under 3/32" (2.4 mm) I think that will work. Brass is self lubricating and requires no cutting fluid. Try clamping the cutting tool as opposed the work piece if that doesn't work. Good luck...WEAR GOGGLES !

i think for a short (2 mm cut) i could use a jewelers saw & fine blade.

for brass tube, i think i'd cut narrower than needed and drag a piece of wet/ dry paper through to a "go/ no go" fit.

time will tell!

RB Motion has parts that might work, as well as a lot of other cool stuiff...good prices , good shipping , all good.

You can get a very thin kerf with etched stainless saws, but I don't know if they'd hold up when cutting brass or not?

I really like the Hasegawa ones, FWIW.

Cheers,
