Hi to all,

I am trying to find some very unusal taps and dies, the size required is 1/16" X 62 TPI and they are used in Sturmey archer hub gears. The thread was the old CEI Cycle Engineer Insturtute which used to use this size for cut threads for spokes before thread rolling started.

I have tried Tracy Tools which most times they have what you want they have 1/16" taps in 60 and 64 TPI but unfortunatly 62TPI.

I have looked at the differances between British teeth per inch and metric pitches but there is nothing that come even close.

The part in the SA hub is a cross nut and the toggle chain and joining rod from the other side bolt up to this part and clamp it tight so the hub can make gear selection,

May be worth searching for 16g x 62tpi as the smaller sizes of thread is based on wire gauge giving a dia of 0.064" not 1/16" or even spoke dies/rollers

Like yourself John, I enjoy a challenge. But can't you find a new old stock unit and save yourself panning for gold?

If you do find a supplier, please let me know as I often search for the most obscure threads myself.

I notice that in MEW 218 there is an advert for Avon tap and die

avontapdie.co.uk
they dont list 62tpi but claim to make any tap or die and as new advertisers may be eager to please
probably worth a call
