Yep, nice work Ian. I had the pleasure of visiting Bogs a couple of weeks ago and he showed me this engine running - very nice.

Ok Fella's, I need advice.

Today I got some brass 2mm sheet for the bedplates, and a new toy, a slitting saw and arbor.

Now, having never used a slitting saw, can I grip the sheet in my vice and cut off a piece the size I want, holding it with, say, a pair of pliers as the cut finishes?

Or, if thats a no no, what do I do?

Boatmadman,  I have often been accused of being a bit lackadasical in the safety department, but I have done what you describe, only using fingers to hold the piece being cut off.  I wouldn't do it with steel particularly stainless, however for brass, I'd have no qualms, but I do have lots of scars on my hands, and my mother shakes her head and never wants to hear.  It will do a bang up job cutting off a piece of sheet with parallel edges, and without distortion along the cut, something of inestimable value with brass.  I don't know what you have for an arbor, but I have avoided multiple size arbors like the plague, not trusting in them keeping the slitting saw flat and tightly held, but have made a separate arbor for each size I need.  For what it's worth, that's my take.   :beer: mad jack

I gave the bearings a nice cosmetic cut today, the first pic shows them with a set of crank web blanks.

The second pic shows one set of ten webs almost finished.
