No 2 morsetaper tap holders are available on our favourite auction site, Ibought 1 and stripped it and made a few for common taps but also use a tapping chuck and most of my tapping is done under power usually fast backgear and using the VFD preset reverse and as the point is reached press he green button and lathe is reversed ejecting the tap.

I would look into your anti corrosion oil it obviously doesn’t do what it says on the tin. Try hydraulic oil.

I have made all my expanding mandrels but I’m afraid Roy I drew the line at tapered bc mandrels, they are nice and hard and last for ever. On your Homemade mandrels if you fully thread them then internally cone with a LARGE centre drill, make a matching coned washer you get a good amount of outward pressure meaning you are able to remove significant amounts of material.

Martin, The reason being that you would need another tangential toolholder of the other hand. Plus the blank is butted up to the collet chuck nut so no room to get to tother side

I used the single button method with a twist , the button was a length of carbide mounted tangentially and 1 side of the blank machined then taken off the mandrel and reversed and the second side machined. This was for Wildings turret clock which works very well.

I used to have one and the jaws where 90deg vees to take square stock.

That looks a handy piece of kit Geoff, I’ve made one for the Myford so looks like I’ll have to make one for the Peatol.

Fowler’s fury, it’s for length machining

I have something very similar on one of my Peatol and use it with live tooling, it works very well and of course repeatable which is what you are after.

There is a company local to me that supplies the furniture trade, french polish etc. That still sells Nitromores stripper they buy in large quantities and decant it. I wouldn’t think they are the only company in the uk who are doing it.

I have 5 machines in an unseated and uninsulated garage but don’t suffer with rust problems, I put it down to using hyd oil as a cutting lube.

Odd thing to do as they are out of stock with so many items

8 or 10 mm washers slid on to a piece of 3 mm bar which rests on the vice jaws?

Roll on Sunday dry and clear here get a run in ther will be less of them for the next few months!!

Sorry only just seen photo of application, my helmet chain is inside a cycle inner tube and I also use a laptop security cable whic Iut through the sleeve of my jacket and use a long shackle padlock.

If you buy hss beware the chinesium it’s rubbish, I recently bought over 60 inches of 5% cobalt blanks from makers incl eclipse , j&s, clarkson etc. for just over £20 plus post, more than I will use in the time I have left so why buy this other c..p that doesn’t work?

Modern push fit plumbing pipe??

8.8 and better is absolutely OK to machine with HSS, your turning speed looks a tad high.

I seem to recall that the tri lobed screws where called Taptite as they were hard and screwed straight into sheet material making their own threads. I still have some they must be at least 40 years old now!!

Books section in classified ads has approx 18 items of which less than half are books. I have deleted two of my ads from this section perhaps that’s why I have had no takers!
