sorry its a crapy pic . start of with a shaft with a very light tapper on it you have to buy a remmer with the same taper . the cast iron peice is taper reemed inside with a cut to alowe to open when to parts are pushed together run some light groves in the cast iron to alow for sluge to get in . the is a cuting compound to be used and diamond past. you maybe able to just buy one. hope it makes sence![]()

Don't you look at my accountant.
He's the only one I've got.
Thanks crazy for your advice, set me in the right direction.
Made some progress, I wasnt happy with the boring tool so I made a tool holder from an old lathe boring bar that takes 3/16" HSS, ground up a tool and had another stab, reground it a couple of times untill I was getting a nice finish in the bore. Thought I better check the size and it was 22.2 mm well thats a bit over, never mind this is just a test crank, big mistakes are welcome!
Went to Cliff Bond and got some cast iron to make a Lap with and while I was there got some CI to make a sleeve with. Funny place going out the back is like stepping back in time, all old machines most older than me by a good margin. While I was there an old guy brought a Model A piston in for rings, $95 for a set for 4 pistons, then another old guy came in with some old sidevalve bike barrel he needed 1 extra ring because he broke one. Cool place, no EFTPOS
My neighbours diary says I have boundary issues
Ferry Road, ChCh where they've been since WW2....
Suppliers of rings for damm near anything too - they have a private online catalogue which enables them to find rings if you ring up and quote a bore size and ring widths....very useful. one example...Nissan LD28 rings for a Benelli 650 twin. Better than OE - and cheaper.
you had to gloat didnt ya........tomorrow old man tomorrow!![]()
Its harder to lose weight than gain horsepower.
