well i managed to do some more work on this project, so i figured i had better start on the cylinder head. i think it is the most complicated part so here it goes.

the cylinder head that i'm copying

here is a picture showing the head beside the chunk of steel that will ( i hope ) become the new cylinder head.

i chose 12L14 for the head just because it machines easier than normal cold or hot rolled.

the next picture shows the piece merrily spinning in my lathe. the combustion chamber has been machined out and i'm turning down the o.d of the head.

then after the o.d. was close to size i marked out the outer profile of the head. i will be using the mill and rotary table to cut the outer profile.

well that's all for tonight, hopefully i will be able to work on this for the next few week's without any interuptions (like that will happen) :lol:

chuck :wave:

chuck foster:
got a bit more done today :clap:

here we are milling the outer profile of the cylinder head

now i must apologize for the lack of progress photo's but the truth be known the wife borrowed the camera and i didn't want to wait for her to return it.
so the next photo shows the head almost done

the square hole cut into the side of the head is for the ignitor

this last picture shows the top of the cylinder head and the two 3/8" hole are for the valve guides

i used 12L14 steel, what a treat to use :ddb:

now all i have to do some file work to clean up all the machining marks and press valve guides in, but that will have to wait...........domestic duties call :bang:

it was allot of milling and lathe work but it went well and i enjoyed the whole process.

chuck :wave:

Powder Keg:
Any updates Chuck? That bore looks great!!! Where would one find laping compound?

chuck foster:
hi wes: i just roughed out the cylinder head in the previous post dec/13/09, hope to get some more work done on it tonight.

as far as the lapping compound, i bought all of mine on ebay. i never looked any where else, im sure a google search would turn up several suppliers.
