Hi folks!
So I'm at the part of my Muncaster Joys Valve Gear engine build where I have to think about getting all the pins and fasteners done, and have some questions about the pins used in various places.
The crossheads appear to use pins with a round head one one end, and a spring clip and washer on the other:
These pins are riding in bronze bearings, so my questions are:
1. What material should the pins be made from, and should they be hardened?
2. Where I can I get (or how can I make) an appropriate spring clip?
I know I could just put a thread on one end and and have a washer and nut bearing on a shoulder on the pin, but using a spring clip seems more prototypical.
There are also lots of other pins between the various linkage parts, some of which have no clearance for heads, so should these just be a press-fit into the relevant parts? I suppose I should have made a rotating fit hole on the inner link, and a press-fit in in the webs but I didn't think of that at the time
What's the best material for these smaller pins, and should they also be hardened? For fitting, a bit of Loctite would prevent them from moving, but I would like to ensure things are easy to disassemble.
Many thanks!
Simon
