Paul,
Been up to the machinist this morning - all seems to be going well and
we clarified some points in regard to the starter motor.
BTW I didn't use the local chap, I chose a well known workshop
with CNC capability to establish the protocol for on going
production. The set-up cost are 'an arm and a leg'
but ongoing cost will be minimised because of the CNC process and also accuracy will be assured.
As the machining is being mostly done from the back side, holding
it down proved to be difficult, so the machinist milled the
strengthening ribs sufficiently to get a stable base to clamp the job down.
Because these ribs are somewhat overkill, this
process didn't concern me at all except it may leave a little squarish
edge which may need some rounding-off.
Surprisingly the stand-offs (internal mounting points) are reasonably
accurately placed - not perfect but pretty good.
The sides being tapered (draft) seem to be the biggest problem,
especially with the internal concave section at the top - who
insisted on this again !? I'm wondering if it's worth it.
Anyhow that's the status to date - no new photos yet !
Don't want to rush it at this stage.
