    Ah yes, looking at it in that context, it does look more like an ampersand - so it fits my No. 10 BB :). Did think it a little strange that a date would be put on that individual piece! Thanks Andy. I did wonder that too but then thought it's too localised - I would expect years of pushing...

    Hello peeps, time for an update after a bit of gap as it's been a while since I've been able to do any work on the beast. The degreasing has been done and a final rub down. Remember the stamping I found on the fixed chassis? Here it is cleaned up: 'No 10 BB' Found another stamp on the...

    I've done some drill wire brushing today to remove the worst of the corrosion. Here are some pics of the bars and the junction with the face plate. Difficult to tell if welding has taken place but, if not, that's some ugly looking casting in the second pic (like I'm an expert :whistle:)...

    O frabjous day! Callooh! Callay! I just drilled out the 5/16 BSW screw, used a tap of the same size and saved the internal thread! I is a happy bunny. :) Having a closer look at the undercarriage, I've found a stamped number. Can't quite read it yet but wonder what it might be - a casting...

    Well hurrah. Mission accomplished! Didn't bother with heating and went straight to drilling and got it clear. Managed to go through 3 drill bits mind - pressing too hard I imagine. Additionally, very happy to report that the UNC 10-24 screws I (optimistically :)) ordered actually fit! Next...

    Drill and pick was the conclusion I was coming to but hadn't thought of @dickm's suggestion of heat treatment. As they say, I won't try the heat/freeze but I'm sure a bit of judicious heat won't go amiss. Stay tuned :) BTW, tried the new bolt in place and it looks fab!

    After a conversation with @dickm I thought I would try grinding the hex-head bolt to a square head. Here's the original (with the bent one as well). All in all, I don't think it came out too badly and the, er, heat treatment from the grinding wheel has discoloured the bright steel of the new...

    So gratified by the helpful comments here and the offers from excellent baccy tins! Thanks for that information @TominDales . I haven't removed the screw yet but I've just bought some Deep Creep to see if that loosens things. I'll also see if I can find a BSF 3/16 but will be keeping my M5...

    My one has cast sliders, two screw holes on the front face and the shorter fixed undercarriage. I looked at the smallworkshop.co.uk history and figured it was the Mk II. However, I'm sure the little qr plate securing screw will be the same between the different versions. Thanks very much for...

    I know what you mean - I have a missing bolt on the half-nut and a bent one on the runner back plate. I did a crash bit of research into imperial bolt sizes and found there are two main thread types: fine (UNF) and coarse (UNC) determined by the major diameter (the distance from the outer...

    That restoration looks lovely. I've just embarked on my own Mk II restore but I've mullered the slot of the small screw holding the quick release bar to the qr lever rod. I think I'm going to have to drill it out so does anyone know what size screw I'll need to replace it with? Thanks in advance.
