Hi All,
Got the rocker gear done. When I order new material for the head, I will order material the I can then machine rocker support bosses in the head. This one is being made out of left over material from other jobs.
Also got one of these edge finders, should have got one ages ago.

Cheers

Hi All
Received some new tools this morning, 2mm broach and two adaptors for it 1/4" & 8mm. Also a MT2 ER32 collet chuck for my dividing head. Broach makes key ways very easy to make. Centre mark is at 0 deg, done while machining cams.

Cheers

Hi All,
Got the crank and front housing done, will have to finish of the front housing when I get the crank case material. Still have to harden the crank pin and polish, have the cam to do also, will do that when every thing is ready to put together.

Hi All,
Crankcase material arrived, After all the machining, and checking piston deck height, then tapping all the holes fore the assembly screws, tap broke on the last hole, one of the cylinder hold down bolt hole. Should of used a new tap, the one I used had done quite a lot of work and some stainless in that. May have to scrap the part and make another one, I have the material.

Cheers

Hi All,
Split keepers sorted. Just waiting on the timing gears to arrive on the slow boat from China, 2mm keyway arrived this morning.

Cheers

Nice work Ghosty. Not far off from a runner. How will you remove the split keepers if need be? Noticed there aren't any jacking screw provisions.

Parksy, 1mm gap between flange on keepers and flywheel, have a tapered tool to pop apart, easy. I could also drill and tap keeper flanges between keeper bolts:)

Hi All,

Hi All,
Had one delivery today, started on the cam box/rear cover, will be a lot of carving when all the internals are fitted. Also done a double check of the shaft distance between the cam and drive gears.

Cheers
