Side Valve IC engine
NormanV:
The intention was to remove the board after doing the first ramming with sand, but like an idiot I forgot. This meant that the casting has a flange all the way around it! The inside of the casting turned out well so I will just trim it down rather than recast it. I also had some of the sand break away on the outside but that will machine off.
awemawson:
Not too bad at all Norman - heck of a hot day to be casting !
NormanV:
It was the warm weather that made me want to be outside, I didn't spend much time standing near to the furnace though.
The sand was lovely and warm, last time I did any casting it was near freezing!
vtsteam:
Now that is familiar looking!!
First casting for my Tecumseh 6hp IC to steam engine conversion.
Good work, Norman! :beer:
NormanV:
Gosh, they are very similar!
I've decided not to be so lazy and to cast another cylinder head, the metal is in the furnace as I type.
I had stupid problems moulding the sand. First attempt, I'd opened the mould and put in a screw to lift the pattern and as I removed the screwdriver from the screw it caught in the Phillips recess and dislodged the pattern. Second attempt, the sand dropped out as I opened the mould! By now I had run out of talcum powder as parting so I used some fine dry sand, that worked fine.
