Thanks Elliot, I think it was you who posted the link to the clickspring site (re my tiny clock handles). I’ll have a look at some watchmakers supplies.

Steel workers who erect the skeletons of big buildings, bridges and similar use something called a "spud wrench"

The tapered holes for alignment pins are made by drilling and then reaming with watchmakers cutting broaches. You can buy them individually or in a set from watchmaking tool suppliers, who also sell

A recent thread had a link to the wonderful clickspring YouTube clockmaking videos, and I was intrigued to see him use ‘taper pins’ to be able to accurately realign two plates( or, presumably,

Jaws made for a scroll chuck are not the same.? The teeth are at different positions to accommodate the spiral of the scroll. Some might assume that scroll chucks would have 3 jaws anyway and not

Did you get the chuck new? One explanation I can imagine is that the jaws were not original to that particular chuck and were made for a chuck with a ring type adjustment that drove all four jaws at

Hello Stan: I've numbered the jaws on my chucks and the mounting pins for the spindle. My thought is if one part is damaged, putting it in the same spot will not spread the damage around. Also if you

Just a guess, but there ARE manufacturing tolerances.? There may have been a selection of jaws that fit best.? And after that, they were numbered.? I'm assuming there is some sort of matching

Hello the Forum.? Looking at a Unimat DB / SL 4 jaw check, the jaws and jaw positions ARE numbered 1 thru 4. Somehow I doubt these were fitted to each chuck. With 3 jaw chucks, the individual chuck

John, the only benefit for me with this one i picked is you can input up to 60v and i don't need reverse, what i am thinking is for the U3 i have a 24v transformer coming as well and it can used

May I ask please what is the benefit of this particular motor speed controller over any other?? There are any number of controllers on Ebay.

Thanks Ed, They look nice and I am sure thet work nicely, however I have begun making my own set. I am useing 303 Stainless ?Steel which is free machining and I will engrave the dials myself. I get a

This is the set I just bought? second one for me? MUST be used over METAL handwheels? I have one set on my U3 https://www.ebay.com/itm/226565177907 send seller a note he may help you, not a normal

Exactly, and the response of the motor is an important part of feeling what the lathe is doing. A speed readout is just a distraction. Old industrial production machines used an Ammeter to see how

Great stuff. I don’t know if you dabble with electronics but I also made a simple speed readout using a Hall sensor, an Arduino board and a small display. The Hall sensor detects magnetism, so you

Thanks Peter, just been and ordered two of these. Phill

PWM (Power Width Modulation, I believe) controllers are readily available online… the ones I got (I have two motors also) have a three way rocker switch (forward, off, reverse) and a potentiometer

Thanks to all for the information, I have not been able to find a pdf of the motor spec's, why I asked the bench supply has a max of 30v so I am winding it down to 24v to use the lathe and wondered
