The actual headstock can be locked at a required position the use of a dial comparator makes the alignment of the tail stock straightforward .

the lathe was purchased for its ability to used as a bor mil lathe for basic machining ,I have been using the ability of the head stock vertical movement to cut the new gears required to replace the missing change gears .

I shall fabricate the gear banjo's, machine a new chuck back plate with an 1-7/8" 8TPI thread, remove stuck chuck "machine off as last resort" which will release the full potential of the little Murad.

I have retired from a working life in engineering ,time served indentured apprentice at John Thompsons Boiler makers worked their most my life as:- draughtsman ,boiler maker, fabricator ,maintenance fitter, welder. Had to change jobs as the work gradually declined. The lathe in the Mars shop was so big the turner had a table and chair on the tool post it's a housing estate now.

Quick up date

Chuck stuck fast, Working on change gears and banjo's to enable me to turn1-7/8"x 8TPI .

Managed to source a 1-7/8" x 8tpi face plate, also most the change gears to enable me to turn the required thread form, if I have to turn the back plate off and turn a replacement.

It will require a extra banjo due to the ability of the head stock to raise and lower.

The compound slide as more slack than you no what so will need sorting. Was it worth it ? you bet first time my mind as been in overdrive for a long time .

Thank you for your reply Michael.

Looking at the photographs visually, I think I am on the money and it is they way I will proceed .

Made progress tweeked and cleaned all slides fitted new gib screws .

One thing that is puzzling me is .according to literature the largest lead screw driven gear is 100t at 12dp this would give me a gear dia of 8.5 " it will not fit inside the guard case. The gears that came with the machine are 16dp, 100 teeth gear at 16dp =6.375 they will fit.

I can only conclude that the spindle stud driver is at 16dp together with the rest of the change gears up to the lead screw and that the spindle gear driven is 12dp.

does this seem logical?

Well so far so good.

Seems to be in a fair condition ,I have not run it up properly as yet as I need to change the oil in the head stock bearing housing .

The change gears that came with the lathe are 16DP whilst the gears on the lathe head are 12DP At the moment I am try to find out the details of the gear change banjo that was used on the lathe.

The one thing that I can see being a pain is as both head and tail stock at movable in the vertical axis, is setting headstock to tail stock after any adjustment ,for this reason I have ordered a Dial Co-Axial Centering Alignment Indicator.

This little lathe fits perfect in its new location, yes it was a good wedge but it is already keeping me mentally active ,I spent a good number of years as a maintenance fitter and coded welder so looking forward to making swarf in my sanity box.

Thank you all for your interest and comments.

The lathe arrived on Tuesday, the former owner as had the lathe for the last twenty years and has now moved up to a larger lathe. It was in far better shape than the flea bay photo's implied and came with 4 change gears, 3 of the guards and the lead screw dial.

I shall give it a good clean check for wear and mount it on a bench and let you know how I get on and what needs attention.
