Dear Rebekah,

You could (and this will make the purists squirm). Select the closest imperial thread pitch to the mm one and partialy screw cut your threads. Finish with the metric tap and die. The advantage is that by screwcutting the thread will be central and true to the axis.

Dear Trevor,
I have had the Newton Teslar unit on my lathe for 10 years without a hitch, they are worth the money. You will find the lathe runs ultra silent as the primary headstock drive is via a toothed belt which also result in a good finish. The original motor was 3hp but I have fitted a 2hp which gives plenty of power. My view is it is a little dangerous having a very powerful machine tool in a home workshop where the operator is on their own!

The motor pulley size is not fussy, I run my machine with 2.5dia pulley using 2 V belts (the lathe is fitted for 3 belts)

Last year I completed two big 7.25 engines with all the turned parts machined on my Chipmaster. Dont be afraid to give it some work to do, it is an industrial standard lathe but use some robust tools, non of these Micky Mouse tools used on ML7's! Having said that I have also screw cut threads down to 3mm dia on stainless,

If its in any reasonable condition you will find its a very ergonomic machine, light to the touch, responsive and the cam-lock chuck is great.

All the best,

Dear Trev,

I have a Chipmaster which I baught 10 years ago for 500 Pounds! As mentioned by Ian I kicked out the variator and fitted a Newton Tesla variable drive.

I find it amazing that more people dont use these machines which are available in good condition for less than a Myford of a far Eastern import. The Chipmaster will beat the socks of any of them.

Fit a Newton Tesla speed control unit with a standard motor 1500rpm. I have one on my Chipmaster for the past 10 years and it will give you the full speed range.

Dear All,

I do feel, that unless there is some specific objection, readers should be kept up to date in relation to staff not being well. I see ME as a family magazine with all those who contribute or subscribe as part of the family.

Until today I did not know Peter Rich or David are ill. Likewise Keith Wilson just disapeared from the pages of ME and I only learnt he had had a stroke when his son contacted me.
