Two piece poppet valves

(1/5) > >>

jcge:
I put together this order of operations for making two piece soldered poppet valves. Hope it proves useful to others.

John

steamer:
Thank you John!

CI:
Thanks for the info.
Would that be a press-fit ?

.

jcge:
No need for a press fit. A successful solder joint relies on clearance and capillary action.
A small chamfer on the narrowed stem where it joins the head leaves a nice ring of solder which marks the transition point from stem to fillet.

Thanks John, for those of us to whom ‘order of operations’ does not come naturally, this is helpful.

Regards, Paul Gough.
