ACME tap set for mill/lathe feednuts: FA

The following is part ad, part membership drive:

First the ad. I've put a set of ten ACME feednut taps on eBay, which may be of interest to anyone with ¾" x 5 tpi RH or LH feedscrews on their lathe or mill, plus a 1" x 5 tpi LH set which is a common requirement for mill vertical feednuts. This adds up to a very nice set in excellent little-used condition. There are three to four taps per size so that nuts can be cut starting from a plain bore without any need for rough screwcutting to size first. The taps are eBay item number 7565085332.

Now for the membership drive. The set of taps above covers precisely the sizes needed to cut all three feednuts for any Tom Senior horizontal/vertical mill. So if you have a TS M1/Major/ELT etc with more backlash than you'd like, these taps could be the answer. If you have a different problem with your Tom Senior machine then the Tom Senior Yahoo discussion group could be the answer. We have getting on for 100 members with every model of machine and accessory covered, so there's bound to be someone who can help with your questions (or someone you could help with your answers). You can join it by visiting

As an added incentive, anyone who wins the above taps will get a 10% discount on their winning bid if they've applied for membership of the Yahoo Tom Senior group at least 1 hour prior to the auction closing.
