Members gordond Posted April 18, 2015 Members Report Posted April 18, 2015 Hi all in conversation with Constabulary about needle clamp screws for the BUSM HM6- what screw system are they? none of mine line up with BSW [or BSF] or any other system.. I believe Al has been through this before and ordered some offshore - but they didn't fit? just putting this out in the public domain 'cause no doubt; it will be asked again [unless it has been already!] Quote
Members amuckart Posted April 18, 2015 Members Report Posted April 18, 2015 AFAIK all the screws in the BUSM machines are BSW. I have a mate who go,unreels at MOTAT who has access to all kinds of thread guages. If you want to send me one I can get him to measure it. Quote -- Al.

Members gordond Posted April 18, 2015 Author Members Report Posted April 18, 2015 (edited) Thanks Al - will send you one that is "intact"-- we put 3 screws over all our gauges at work and no match on common BSW... thought they might be a very old BA system- but we don't have a gauge here is one that has been stretched and basically cross threaded Edited April 18, 2015 by gordond Quote

Members gordond Posted May 11, 2015 Author Members Report Posted May 11, 2015 sorry taken so long to get this sorted ...I took out the screws out of 4 machines and took them to work to size before sending to Al. but they are all different !@!.an array of retapped metric [4mm] ,maybe Whitworth and munched up odd screws...everything from 3.5 - 4mm Conclusion: ?? -without knowing if they have been altered - it's really a best guess to fit something [not the answer we were looking for but if this is the state of affairs[altered] - then ordering an "original" is going to be hit and miss with these antique machines] Quote
Members Constabulary Posted May 15, 2015 Members Report Posted May 15, 2015 I´m about getting 2 new (hopefully original) screws. If they don´t work I´ll tap a 1 size bigger metric thread.

Members Singermania Posted May 28, 2015 Members Report Posted May 28, 2015 HI All, I managed to get off the shelf ones that fit, the people that bought the Canadian ones found they don't.... Quote
