Linky Winky was bad enough, but LATHEING!

As the sign in Sergeant Bilko's mess said "Mind your language, unmarried men present"!

Turning, PLEASE!

Sounds like you need to adjust the headstock bearings. There should be less than a thou of measurable up and down movement at the spindle, when pushing or pulling on a piece of bar held in the chuck.

Scroll down to page 5 of the Drummond booklet in this link and it gives the full procedure for adjusting the bearings and a good cross-section drawing of the headstock and bearings showing how it all works.

Best fix for the broken backgear tooth, if it is completely missing and unuseable, is buy a used pulley/gear unit on Fleabay. Might be a chance to upgrade to V belts if you dont already have them.

Happy laveing.

Here's the current state of my scrap lashup fixed steady, the 1/2 HP motor is making big jobs miles easier

A 10mm plate for the base, a 1 inch pedestal and a 5 inch ring, plus assorted other bits underneath, all glued together with a 40quid Lidl buzzbox

Lots to still do, tidy up etc, the 30quid Lidl angle grinder and base are making any welding mistakes or messy bits miles easier to remove, sort out and redo. If you ever take the "welding route" an angle grinder is an essential part of the setup IMO

Update on my Lashup fixed steady

The Lidl inverter welder and angle grinder tidied up and finished things off and I started doing some rebar for more stock which involves annoying intermittent cuts

Anyway, the family braincell was active for once and this fixed steady allowed for some serious improvements I had never foreseen

I used the fixed steady to support my live centre, which flexes with heavier cuts because there is always that inevitable overhang

The improvement was massive, so much so that I popped in a 5% cobalt tool and on the backgear I can run up the entire rebar with a single shaving cut, completely eliminating any intermittent cutting

Looks good. Some serious swarf being made there. Good idea on the centre support. Makes up for the somwhat spindly MT1 tailstock centre.
