I have been inundated with work since xmas so progress is a bit slow, however all
heads are machined up, just need threading.
Valves, 10 done
Guides, 4 done.
Having fitted the guides to the head (as pic), it is hit and miss that they line up
squarely with the head, of 4 giudes fitted, only one lines up nicely with the
head allowing drilling of the exhaust/inlet ports.
I have machined one giude to get correct fit, very time consuming, this thern makes
each head assy a matched set, so parts will not be interchangeable.
Perhaps shims under the guides might work?
Also had to machine the hex back from the end by 0.5mm to stop the corners of
hex from marking the head on assembly.
hopefully get some machining done today, unless shed is an oven!
