Hi all,

I have been working in NZ for the last few months, so have not
progressed at all, perhaps I could take up Aussie Jim's kind offer
of helping with the valve spring retainers.
Otherwise ready for seating valves and pre assembly, oh, and
thread sparkplug holes, just need to verify the thread used by
sparkplug maker.

Dave

Help! It's all in French!!! That's if I am looking at the right drawings.

What sheet are the valve spring retainers on? And what are they called?

And I need to make 6 sets (or is that 7) right?

Jim

Thanks Dave, I think I have identified it but the hidden lines on the drawing worry me a bit in case there is something I am missing.

Are they brass or steel?

And please send a PM with the address to which I should send them.

I am looking forward to being useful.

Jim

Hi Dave,

I think I have made one collet. Think? It is so bloody small that I am not sure. I vacuumed the lathe first so I could find it when I parted it off and I think the bit I picked up is the collet but I won't know until I find a way to hold it to remove the flashes.

So far I have broken all of my 1mm drills but now I have made a sensitive drilling attachment (you wouldn't do it while you still had drills, would you?). Now I have some more drills and can have another go.

Please send the drawings when you can just in case I am making the wrong bit or the right bit the wrong size. And the address for sending them too.

Cheers

Jim

I have made a small change to make them a bit easier make.

send to you.
Will send a PM later today.

Dave, got the PM and have responded.

Do you think the collets would be ok if I just milled the slot? The only difference would be lack of radius at the bottom.
But I could then mill the slot for all the collets at once and then shape and part them in the lathe.
It's just a thought and I don't want to spoil the job just be being lazy.
Let me know (or maybe I should just wait for the drawings)

Jim

Thanks Dave, I got the drawing and the sample (beautifully made sample) and will start on them tomorrow or Thursday.

Jim,
Regarding your previous comment on the bottom of the slot, it is
my opinion that it needs to be radiused to match valve stem otherwise
there might not be enough load bearing surface to minimize wear.
I will leave that up to you!
The assembly I sent is the previous design, but valve and retainer
dimensions remain the same.

Dave.
