Washburn g10v micro adjust
Hello,
Help needed please! 🙏
It’s a Washburn g10v that I am trying to source parts for.
The owner wants to do a full restore but we can’t move forward with the job as the trem is missing the micro tuner thumb nuts.
The trem is a big old rare thing with 2001 on the edge of it.
Please see picture for reference.
(Taken from reditt, a common problem it looks like)
I have one of the thumb nuts here and I think it’s a #no.5 -44 UNF thread.
But it’s so small I can’t get my thread gauge down in there to measure.
It’s measuring 0.125” across the internal diameter and it’s definitely a fine thread.
However, I think these things were part made, if not fully made in Japan, so could also be a fine pitched metric thread.
But I suspect a 3.175mm dia machine screw is less common, so going to assume it’s a no.5-44 UNF for now.
These things are like hens teeth! And the whole project is hanging on the procurement of a few tiny little obsolete parts.
I hate it when that happens!!
So I’m struggling
I’m struggling to even find anything UNF pitch in the UK.
It’s really more of a North American thread gauge and very uncommon here.
Even a pack of machine screws to test my theory is proving difficult to source, and that’s just to figure out the thread pitch of this thing. Let alone finding a replacement.
Unfortunately I don’t have the bridge here, just one of the thumb nuts.
It has straight knurling, domed top
Overall length of 0.354”
Outer dia of 0.321”
internal recess is a straight counterbore of 0.120” deep.
And 0.147” dia.
Does anyone have a source please or any idea what to do?
I don’t really want to have these machined up especially,
because firstly I don’t know anyone who could do it, but secondly, most machinists won’t entertain small batches of anything.
Thanks
Nigel
