thread / screwcutting and gears

the spindle is 1" 3/16th as a quick measurement and about 1/2 long. i think ill try and make it fit, if all else fails least ive practiced and learn from it, then if it all goes down the pan, i can buy one.

cheers all for your help.

well, it worked, talk about a steep learning curve, cut my own 55deg internal thread tool form hss steel. then turned the thread into the inside of the faceplate. (well after flattening the old thread) and now just touching up the outside. but it all worked well, even using the gears etc to get the right thread, i did turn it by hand though to cut the read, ensuring slow speed!!!

thanks all for your help..

That's great, Lloyd. Turning the spindle by hand takes much of the drama out of a stopping in the right place on a fairly coarse thread where the tool would gallop along under power, particularly when it's a short thread only involving a few turns.

Clean up well; if the faceplate is cast irin, there'll be black dust everywhere, and it's abrasive.

Hi Lloyd & Guys
I use one of these for turning the spindle when dieing & screwcutting a sprung loaded handle for safety it pops out when you leave go.

good idea, i also found out that ive been a muppet, and the numbers stamped on the gear ar not the what all the gear are, so ive got 60, 52,46,32,32 and 28, which does give a bit more of a range, oh well, as they say, we learn something new every day, and it never stops.
