Side Valve IC engine

<< < (8/10) > >>

NormanV:
Here is the new cylinder head. There is quite a lot of flashing on it as I made the pattern without any draught and relied on the rapping to loosen it in the sand to allow removal. The recesses on both surfaces are fine, I've a bit of cleaning up to do but the time saved in pattern making more than compensates for that.

NormanV:
Here it is after a few minutes with a file and a hacksaw.

tom osselton:
Turned out well!

vtsteam:
Looks good Norman! :thumbup: :clap: :beer:

NormanV:
I got back to boring out the cylinder of the engine. Firstly I had to make a more rigid boring bar. My 12mm dia one was causing chatter. I obtained a piece of 22mm square steel that was the largest size that would fit my toolholder. It made quite a beefy holder.
