Very nice work indeed Rob.

Makes me want to get back into the shop for a few hours fiddling.

And I thought they were just while you were building it, to be replaced by studs, washers and single chamfer nuts, proper job :thumbup:

Fair enough, it did seem a little excessive!  :lol:

I'd best get a few other things finished first.... Like my long awaited house!    ::)

A bit more work on the engine tonight  :dremel: , repositioned the R/T to HZ  and drilled the inlet and exhaust ports .
 

Chopped the head off from the stock and skimmed up the face .


Just needs the valve seats cutting ,, i will probably make up a seat cutter for the job .

Thanks Lads and cheers for looking in  :headbang:

A wee bit progress today , turned up a couple of brass valve guides  :dremel:


Next was a couple of stainless valves ,, i decided to turn them from 1/4 bar instead of the described method in the drawings .


Then a couple of valve spring keepers also in stainless





Time for tea  :med:

I cant remember seeing a microscope in your shop but you must have one  :scratch: :scratch: :scratch:

Cheers Lads  :beer: :beer:

Just a bit of an up date ,, Things have been a bit slow had a few other workshop jobs to take care of  :dremel:

Any way ,, the flywheels up next .machined up the flywheel blanks and decided to CNC the cut-outs for the spokes  :dremel:

Here is my small CNC set up Denford Starmill and Mach3
 

Mounted a 4 jaw chuck to hold the blanks ,,,,,,,,,, going to make a proper fixture for flywheels  :proj:



I used the find centre wizard in Mach3 to locate the blank centre


Then off we go  :ddb: :ddb: :ddb: :ddb:



NOT FOR LONG ,,,,,,,,,MACHINE TOOK A MENTAL  :lol: :lol: :lol: :lol:

No idea why it just did  ::)

Machined up the second one ok ,,,,,,,, wile it was chugging away machining the second blank  i turned up another  .
