Thanks for posting Tony.

I agree it is a gamble, do you order and how many ...
The price from PCBWay drops dramatically once you get into 10s and the freight gets better amortised with the higher number.

I ordered some sample sintered tool steel chuck keys for the TML 3001 chuck used on the Cowells ME90 lathe from PCBWay.
They have been sat on my desk for a few months so I put them on EBay this week and already had sales.
In the small quantity these were not low cost.
Should I order more I wonder ?
Perennial debate.
