Unless I make it electric. Still thinking. Today I am getting it cleaned up. I think I got lucky there seems to be almost no wear noticeable on it. Might be a few more days before I get at making the winder. Quote
Members catskin Posted October 20, 2018 Members Report Posted October 20, 2018 I thought I would put this here since others might be looking for the same info. Could some of you pearson owners please tell me the size and thread the bolts are to hold an edge guide onto these machines. I took a bolt from the needle steady to try and it is the same size and thread. So I took it to 2 different places to try to get bolts, both sold me bolts they said were right but when I got home they do not go in. The thread is slightly different. Arron martin does not list those bolts separately and postage would likely be more than the bolts. So would like to buy closer. Quote

They'll be Whitworth threads -- either coarse (BSW) or fine (BSF) rather than Uniified National coarse (UNC) or Fine (UNF). The major diameters of the bolts between these two systems will be the same and the minor diameters quite similar but the thread form will be different. I'll measure mine, though there's no guarantee that they'll be the same as yours -- I've heard that different BUSM machines from different eras can have different screws at the same locations. Quote
Members catskin Posted November 7, 2018 Members Report Posted November 7, 2018 I contacted Aron Martin and was told they rethread those places. So ordering from there will not help. They want you to buy THIER feet and edge guides that are rethreaded and the bolts to hold them on. I would prefer to keep this one original. So if anyone can tell me the thread and size I might be able to find them. I have whitworth. metric and unc thread gauges and non seem to fit. Whitworth are 55 degree with a round top whereas unc and metric are 60 degree with a flat top according to my hours of searching the internet. Have any of you rethreaded your machines? And what thread pitch did you use to not ruin the holes and have to redrill and thread a bigger size. Quote
Members Greenwood Posted November 7, 2018 Members Report Posted November 7, 2018 Hey Catskin haven't heard from you in a long time. Leo here from Regina. I bought screws from A Martin and like you said they work well with the foot I got at the same time. I later determined that the screws provided are 12-24 x 3/4 machine screws. I found some at Bolt Supply in Regina and used 2 to hold the homemade edge guide in the existing holes on the front block where the wax box attached. They are not the perfect thread but a drop of blue thread lock did the trick. The screws hold firm and are not seized in place as you might expect. They come 100 per box so I have lots on hand to spare. The next time you're in Regina call me and I'll let you have some. P.S. There was a minimum purchase price so cheaper to buy 100. Call me fivefourfivefortyonethirtynine or fivethreesixeightzerotwofive. Hope to hear from you Leo Quote
Members Silverd Posted November 12, 2018 Members Report Posted November 12, 2018 I'm still looking for a Round Rein attachment for a Person 6 if anyone knows where I can find one. Perhaps if I offer a reward! Silverd Quote
