The 80mm called for would be best reducing to 3" - 76mm so it can be cut from more freely available 3" bar stock,

cut longways? or are you thinking a C shaped version?

Hi Bill
I can get bar stock that is 1/4" thick by 3" wide. That means I can use cz121 (?) extruded bar rather than 1/4" brass plate which would be much more expensive!

Or if that doesn't work, item 400441260894 on ebay

Ah! FLAT bar stock :doh: (must learn to read)
Yes, that looks a better price.
1/4" thick is going to need a much bigger bull-dog clip
Will they cut to any multiple of 50mm? I'm thinking a length of 350 would give you two pieces ~175 long
raynerd:
I have purchased the brass needed for the depthing tool today - 1/4". Would two large bulldog clips be more suitable?
Could you just explain your thoughts on bearing size for the pivot/hinge? You mentioned 4.5mm in a 4mm reamed hole. You also mentioned that slightly larger may be better for the hinge - why? And what size - 5mm, 6mm?
