I want to upgrade my heavy equipment bolting methodology by incorporating ‘Extra Thick’ Through Hardened washers.
I will predominately use these washers in bore sizes from 5/16” to 1-1/2” (8mm to 38mm).
These washers are from .125” to .250” (3mm to 6mm) thick.
As manufactured, these washers provide bolt clearances of 1/32” to 1/8”.
However, I prefer all critical washers to have no more than 1/64” bolt clearance.
So, I would need to enlarge the existing bores to provide tighter bolt clearances (i.e. a 1” washer with a standard 1-1/16” bore would be enlarged to a 1-9/64” bore to provide a 1/64” bolt clearance with a 1-1/8” bolt).
What methods/machines/tooling would other forum members employ if faced with the same modification requirement?
Would it be possible to ‘stack’ say 5 or 10 of these washers so multiple bores could be enlarged at the same time?
Presumed appropriate machinery at my disposal currently includes a drill press, mill, radial arm drill, and a lathe.
P.S. No washer supplier that I have contacted will provide non-standard bores unless I order at least 10,000 washers per size.
Regards,
SAE
