I have been given parts of a Sieg C1 lathe and milling attachment. Never to run again as a lathe because the headstock is missing I would like to use it a milling machine only.

I have assembled the milling attachment to the lathe bed and cross slide, it all looks good to go and when connected to the mains the motor spins.

Now my problem is I have no speed spindle control it runs only at max speed. Is there any products available that will allow speed control along with forward and reverse? I know I could purchase all the parts as fitted to the Sieg C1 lathe but was hoping for a simple fix.

Any help would be appreciated.

I'm not sure what type of motor is fitted to your Sieg but whilst waiting for another answer take a look at this link

Harry, The motor is 120Watt 240volt AC, the link product is not suitable but it is the type of unit I want a simple connect up and go.

Carl, I have a Sieg C1 with the M1 milling attachment, the original Chinese control board was junked by the previous owner when it blew and was changed for a British manufactured unit,
I don't have the data book to hand at present, it's out in the workshop and too dark and damned cold to go out there at the mo', but I'll dig it out tomorrow and let you have the details,
The original controls on the headstock are still in place and working, photo's of it are in my albums, would think this unit plus an on/off & speed control switch would do the job for you, think they were around £100 last time I looked.

We have determined that the speed controller linked to is not suitable and that the motor is ' 120 watt 240 AC)....

So how about a photo or two of what you actually have so we can help?

Carl, some details of the Parker control unit in my Sieg, think it's a 506 in mine but can't check without stripping the top off the box,

1st link is for a .pdf user manual, second is a website which gives more detail, no connection to either concerns, just a happy user,
