precision axial cutting of thin-walled brass tube


"Don't think a band saw will work as he wants a slit not 2 pieces."


He could stand it up tall(vertical) and slide it into the blade until it makes the slit, then back out.

I would do that with a fitted push stick, or maybe channel locks or pliers of some sort. It is important that you don't touch the part whats moving.

So you're making a bushing instead of buying one, good man. Whats the purpose of the slit? Squeezing ID of tube to OD of shaft? So width of slit is important? It all depends on what tools you got, dyy888, no, there is not a jig saw blade that wouldn't wander around. Unless you got band saw with ultra fine tooth blade and safe jig to hold it I think you wanta stay away from power tools on this. The dowel idea is great, maybe slip appropriate tube over outside, backing on both sides, slice thru both tubes. Utility knife and guide is good too, several shallow cuts. Or very fine tooth hack saw with minimum pressure. X-acto makes a back saw that would work, seems like a good excuse to buy dremel tool and cut off wheels.Can you make two blocks of wood with proper sized V groove in each face? Sandwich dowel-tube-tube in groove between blocks slice through entire thing. Sandwich blocks alone, slice thru one side at joint, then clamp around tube with one side edges together, slice through slot on other side. Bore hole diameter to hold tube length wise thru block, slide in tube, slice. Bore the hole , saw block apart thru center line of hole, (or only to hole)clamp , slice. Few pieces of fine sand paper in groove or hole will hold tube steady and act as shim or bushing (!) if groove or hole too large.
mae-ling, look back, the tube is vertical, open end on table .
Purpose of slit still eludes me, but making a bushing? The whole idea is groovy.
