Between a visit to the dentist and a friends birthday lunch I managed to fit one of the bronze drive dogs - went in as a nice snug fit :thumbup:

Sweet!
awemawson:
Were I doing it again I would beef up the shank, leaving more meat by the keyway, but also make the PLA model's bore far smaller leaving more the bore out on the lathe. Both bronzes only just cleaned up, at 14.05 mm, leaving slight 'witness marks' in place - perfectly serviceable but not ideal.
. . . but I do have not only a bronze second one as a spare, but several ABS and PLA ones that actually seem to work OK !
nrml:
Is the crown end going to be cleaned up or will it wear into place?
awemawson:
The plan is to let it wear itself in. It has room to settle in a bit, but really it's just a case of watching and waiting as it is used.
awemawson:
After weeks of wandering around various carriers and transport hubs, both in the US and UK, and having paid the HM C&E ransom demand to release it, my Euchner Precision Switch has finally made it all the way from San Antonio in Texas. It's amazing how many places it's been on it's journey :scratch:
Hopefully I'll never need it, it can stay as a 'shelf spare', but being rare as hens teeth it had to be had :ddb:
