I have not noticed this hint before. Use a stamp pad to make an impression on the gasket. Also one of the cheap leather punches from horrible freight is great to punch nice clean holes in the gasket. The one with several punches on one handle.
Dog your like a hog at the trough you don’t stop till it’s done. Still with you Dog and waiting to see this baby running like a clock......did I say .........I.........like....... Don
Yep I would go for the smaller nuts ........ Don
Hi ChrisHere in the UK we have BA thread sizes which use bolt heads and nuts one size smaller than normal. I have even run a tap through BA nuts to get the 'LOOK' rightGreat workCheersRich
Definitely a wise choice to go with the brass small pattern nuts, they look to be more of a "scale" size.My question, is there enough meat in the nut at size in brass, to hold against your steam pressure? The elves might not appreciate having to dodge any brass Frisbees.Don
Hi Chris, You are correct there is no set standard for small pattern nuts. The original US formula for the across flats AF dimension was 1.5 times the diameter D of the bolt plus 1/8". In scale terms, this is 1.5D plus a bit or the next size larger hex. This is close to what J.I. Morris did and I still use the nut drivers made by them. American Model Engineers used the same standard. I see that J.I. Morris has added stainless steel to the brass line but WOW...... they are not cheep in SS.The rule for BA is AF=1.75D which is why one size smaller hex looks good on a model.I see a lot of stuff that claims to be small pattern nuts but if they do not list the AF I do not send them any money.Cheers Dan
