How would you cut 6mm brass...length ways

<< < (2/3) > >>

krv3000:
hi if you look at your hacksaw it shod have two more pins offset put the hacksaw blade on them and it lets you cut it all the way dawn regards bob

I did something similar once and used the bandsaw. But I found the brass curled quite alot from the cut. I'm still not sure if it was from internal stresses or from the cutting. I was able to bend it close enough back but I didn't need anything particularly precise.

raynerd:
Morning folks.
Sorry for the slow reply but thanks for the tips. Got a bit of time to try this today so I’ll let you know how it goes.

Ade, Andrew...just read post 70 on your cnc thread and that’s absolutely what I’m doing. I like how you say you don’t particularly like slitting saws...I only have flimsy ones and haven’t had success so feel the same. The other issue is I won’t be able to move the entire length in one pass so I’m then relying on flipping it around and meeting the cut...which I appreciate in theory should work but probably won’t with me doing it!!

Bobs got an interesting point with the saw! It’s a bit of an effort hand cutting but then I can mill flat.

I’m tempted to have a go with the slitting saw but then it’s £40 of brass and don’t want to cock it up!!  :lol:

Cheers chaps. I’ll post how I get on.

timby:
I don't like slitting saws either but I have found that as small a diameter as possible (cheaper) and supported by big diameter side washers works best.

awemawson:
Rigidity is the key factor, and it needs to be not only in the mounting of the work piece, but also the spindle and machines ways.

Any possibility of chatter and it'll vibrate all over the place.
