Title: lathe power feed conversion
Post by: boatmadman on June 19, 2010, 09:26:05 pm
I have a peatol lathe, which is great, but it has no leadscrew, so, while thinking about how to add one, I thought I would think about a power feed for it as well.

Now, the purpose of this post, is to ask if anyone (FLJ ?) knows of a dc motor speed controller that could be used with a speed control knob rather than with rc, then it could be fitted to the lathe control box.

I think the most common thing to do with lathe controls is fit a stepper motor (+ controller) to them. You can then connect them to a PC and get a CNC system.

Yeah, I have seen that option, but I cant think I would ever need cnc on my lathe, maybe on the mill but thats another story.

I really just want a simple way of improving the lathe and the level of finish.

these two have things that will do you, but think about a stepper motor and a driver, there is someone who does a complete hand held unit that you can dial in a distance etc and it will not be much dearer and have you part way to cnc if you ever decide to go that way.
ill find a link to it

Peter,

Thanks for those, the onestep looked promising until I found it has been discontinued, I have mailed to ask if there is a replacement.

 Cos you din't know where to look, but at least you tried to find them.

 An American mate I made through Skype was amased when asking me about a piece of engineering information he needed took a few minutes at "My End" to find as he had been trawling for ages. Difference is, having retired from a carreer in engineering with a "Smattering" of electronics, having in the past had to find things "The Hard Way", with the now simplicity of T'internet, if I don't know where to look I've had many wasted years.

  Aren't "My Favourites" great??  :-))


   Regards, 'Nother Ian.

 PS, Vindscreen Viper motors are good power units for feedscrew drivers.

Ian,

Well, that confuses me even more :D

  Difference is, having retired from a carreer in engineering with a "Smattering" of electronics,

Being a non retired engineer working in power generation, I thought I would know what to search for %%

Had a reply about the onestep controller. They discontinued it earlier this year, not enough interest in it. Also, he said his programmer broke and was expensive to replace.
