I went to school in the city of London.... making things was what you told the poor up north to do.

so 50yrs on I had always wanted to make my own "bits" on my own equipment.

A very, very nice gent sold me a CL300 lathe for almost nothing and "threw in" a vertical mill and masses of top line and hobby type tools.

OK I make adjustments to commercial "items" and made a few bespoke items for myself........ BUT in the "included" items are a great selection of lathe tools, a few of which I have used to great success in making my own "things" in aluminium and brass, but what are the tools PROPERLY for?

Does anybody know of an illustrated guide to the various lathe tools and what / how they should be used for?

THANKS to everybody..... I can now make educated reasoning on motor spec and finish my project...…..

theres nothing more annoying than producing an elegant construction, simply for the motor to start clicking and going nowhere.

I've enjoyed the too and fro between you all...…. the sort of thing I used to love taking part in but, alas, no longer can

wonderful link

BUT it means absolutely nothing to me....

I'm 70, I'm on a lot of painkiller and too easily confused and frustrated.

to make it worse... I was an electronics designer to chip gate level and was fluent in 5 computer languages plus binary / boolean.... and find my current lack of accruity very frustrating

thanks anyway michael

I suppose the title says it all......

a stepper motor turns in a circular motion with a torque of 1N and shaft diameter 5mm

the motor shaft is then direct coupled to a 8mm x 2mm pitch lead screw

if set vertically with shaft and screw in the same plane what is the lifting force of the screw
