Re: Question for you guys that are tech savvy
The HF controller provides enough torque to run a router.? It has been reported here in the past that it works.? So you spend $17.99 and give it a try.? If it is not satisfactory, use it for

Re: Question for you guys that are tech savvy
Hello: Varying Voltage on an AC motor is very ineffective. It is worse than on DC. For an AC motor a Variable Frequency Drive is a better idea, but is offered mostly for 3 phase motors. I have a

Re: Question for you guys that are tech savvy
My suggested solution is different.? You already have a motor.? If you are using the Unimat only as a lathe, mount it on board, and hang the motor at the back.? Buy a Harbor Freight router speed

Re: Question for you guys that are tech savvy
Keith has helped me a lot in the past and understands what he is talking about. I don¡¯t think I would have had the knowledge to carry this out on my own without his help. My Unimat now purrs like a

Re: Question for you guys that are tech savvy
Before going too far I'd look at how the motor will fit. The usual DC motors will fit without modifying anything, and they are not expensive. The main reason for using the motor you have is that you

Re: Question for you guys that are tech savvy
I may be wrong here, but I thought using a DC motor w/power supply makes for easier/better speed control.

Question for you guys that are tech savvy
My u90 motor finally gave out after many years of use. So while rummaging around I found a spare 1/4 HP. 1750 rpm AC Marathon motor from my old Taig lathe that I was considering hooking up and using

Re: U3 top slide accurate setting
Thanks all for the replies. Dick, yes, I was prompted by Doug Collinge¡¯s ¡®Unimat ER-16 Collet Holder.pdf¡¯ - he uses that method (trig) to set the angle but can measure the distance travelled

Re: U3 top slide accurate setting
Hello Peter: It all depends on how accurate your setting needs to be. For turning a Morse Taper the easy way is to set a good Morse Taper in the lathe and indicate the compound side to match. Other

Re: U3 top slide accurate setting
Hello Peter, I don¡¯t own a Unimat 3, but I can tell you how I set the compound slide on my minilathe. I use a dial travel indicator to measure the amount of slope in a given distance. This method

U3 top slide accurate setting
Has anyone come up with a smart way of setting the angle of cut accurately when using the U3 cross slide - the one used to cut tapers etc? As well as the woeful 'scale' on the slide you also have the

Re: Indexing Attachment
Hello James: Perhaps you could make adapter parts to use this on another lathe, or as a start to a stand alone dividing head. It looks like you get everything but the lathe spindle. Carl.

Re: Indexing Attachment
James,? These are the options that are available. On the 48 tooth the teeth are pretty close and sharp, one may have to make the teeth shallower on the 60 tooth. On Sat, 8 Jul 2023 at 23:58, James
