giamma Posted August 19, 2022 Share Posted August 19, 2022 (edited) Hi guys.. yesterday I retired my doublebass from the luthier for a setup and now a screw from a machine head has been missing..(no comment please) The machine is a Irving Sloane in the picture you can seen the screw..

DaveFry Posted August 30, 2022 Share Posted August 30, 2022 Could be a funny american coarse thread / Imperial size measured in American inches type . I would show it to the guy behind the parts counter of the nearest American motorcycle shiny bolts emporium and make his day ! 1 Quote Link to comment Share on other sites More sharing options...

SubsonicSimpleton Posted August 30, 2022 Share Posted August 30, 2022 Find the nearest mechanical engineers merchant and take the screw there, make sure that you also have pictures of the machineheads with you - they will have the necessary thread gauges to determine what the thread is, so should be able to provide you with something that will work in its place, or inform you exactly what the thread specification is if they don't carry it in stock. If they have something that will be a drop in replacement like a stainless steel capscrew, buy 4 so you have a full set of spares (or if you are ocd about things matching). While you are there also pick up a small tube of non-permantent threadlock compound (a small drop on the threads of the screw before assembly will prevent the screws accidentally vibrating loose). The fixing you have pictured doesn't look like something you can buy off the shelf - if your luthier can't find the missing fixing you might have a bit of a job tracking down one exactly the same unless you can contact the company that manufactures these machine heads directly.

Jean-Luc Pickguard Posted August 30, 2022 Share Posted August 30, 2022 Was the screw there when you took it to the luthier and missing when you got it back? - if so then surely its his responsibility to either find the missing screw or source a replacement.

PaulThePlug Posted August 30, 2022 Share Posted August 30, 2022 It may be sitting on the luthiers shelf waiting to be claimed? Quote Link to comment Share on other sites More sharing options...
giamma Posted August 31, 2022 Author Share Posted August 31, 2022 The luthier told me he found the machine head that way, without the screw, to me seems impossible to lose it because I've never unscrew it.. By the way.. I found the distributor of the machine and I've been lucky because he had a spare part, it arrived yesterday 4 Quote Link to comment Share on other sites More sharing options...
