I will be making a Unertl style rifle scope mount and I need a materials expert.....
The prototype is in aluminum and I used the internals from a set of micrometers to get the hardened threaded shaft and insert
I want to do away with using the micrometer internals so I ordered taps and dies at 3/8-40 and 1/2-40 (not sure what size I'll use as I want a large bearing area on the scope tube.
So help me with materials.
There will not be much wear as the turrets are turned relatively infreaquently.
But I'm thinking about making the entire mount out of some type of bronze.
I've never worked with bronze.........
Questions:
Ease of machining?
Ease of threading / taping?
Bronze against bronze OK?
What type of Bronze should I use? (there are lots of different types)
C510 PHOS BRONZE
C544 PHOS BRONZE
C630 ALUMINUM BRONZE
C642 ALUMINUM BRONZE
C655 SILICON BRONZE
C863 MANGANESE BRONZE
C932 BEARING BRONZE (SAE 660)
C954 ALUMINUM BRONZE
SAE 841 OIL-IMPREGNATED PWDR. BRONZE
SAE 863 POWDERED IRON-COPPER

Thanks in advance!
