Does anyone know what size machine screws are used to bolt the cylinders and frames together on the Mamod Locomotive? I imagine they are 6 BA or something... Many Thanks! Alan Mamodman123 Yep 6BA   Graham-Jilly yep MM ir right   Spule 4 Just got some replacements from this vendor: http://www.steamfittings.co.uk/asp/index.asp alan2525 Thanks for the quick reply! Now all I need to do is buy some 6BA Cheeseheads and another lot of taps and dies! Isn't standardisation of screw threads great...**mumbles UNC, Metric, BSF...ME...** Graham-Jilly I found great dificulty finding ba screws here in aus but i found a supplyer and he isnt to dear either. all the main bolt suppliers only have me these days Spule 4 alan2525 wrote: another lot of taps and dies! eBay.co.uk or, if you live in the UK, here: http://www.tapdie.com/ No dice for us in the US, minimum insured postage is over $44 US!!!! talluncle31 6BA If it is of any help, 6BA is the same pitch as American National Fine 4-48 and .002" smaller in diameter. So you can often tap out to 4-48 and use ANF fasteners. Another useful one to know is that 0BA is the same as M6x1 Murray Wilson Graham-Jilly thanks Murray        The Unofficial Mamod and Other Steam Forum Forum Index -> Locomotives Page 1 of 1
