Just what I am in the market for. I need one of these to drive my 3 lathe station on the CNC I am completing.
One cutter head, 3 lathes (3 shafts, or three butts, or 6 handles or fronts;)
The very front will have the 4th axis.
Pics to come...
Costs for this Frankenstein are adding up fast!!!

NIce set-up by the way.

If you need a 1/2 HP variable speed and reverseable DC motor
Penn State Industry has the setup for $110.

I am using one on my Hightower CueSmith lathe and am very happy with it.

By use of an electronic component known as a bridge rectifier.
Almost all Routers are DC motors with a Bridge rectifier in the line.
The bridge rectifier converts the 60 cycles per second AC to 120 pulses per second DC.

This one uses a control box to rectify the AC to DC, smooth out the pulses to a steady DC, and control the speed not by varying the voltage but by pulsing the DC to the motor.
 
It's in the control.

The control/power supply unit changes the ac current to the desired dc voltage.

The less expensive control/power supply units use a rectifier. The higher priced control/power supply units use a PWM (pulse width modifier) circuits (which are sometimes refered to as timing circuits). Rectifier units reduce the output voltage to control the speed and thus loose a lot of torque at lower rpm's. The PWM circuits are designed to maintain as much torque as possible at all speeds. :smile:

Willie,
Any Idea how slow you can get the machine down to , website says 500 rpm, I have the Hightower as well, also looks like you changed the drive belt and pulley what did you use ?

Thanks
Mark

Yeah...let me tell you.

Try learning to build a machine at the same time you are learing about CNC, G-Code, machine resolution, repeatability, and TONS of other stuff too:)

This is why I walked away from it for a while. Right now I am testing the X azis for resolution and repeatability. 20"deep x 48" wide table that moves under the single cutter head- STATIONARY GANTRY STYLE they call it- W/ (3) taig heads and tail stocks- linked togehter via pullys and belts.

Try indicating the linear rails 20" out from the head- 18" apart...making sure they are level and parallel to eachother...NOT FUN. Bought a machined 4' level from Home Depot (.0005 per inch) and I have a 18" machinist level to put on top of it. Best I can do I guess.

ANYONE HERE HAVE A BETTER IDEA ON HOW TO GO ABOUT THIS????

If I can get the mechanical repeatability, then I will move onto the Y which currently has 53" of movement. I bought a lead screw assembly off Ebay- didn't realize it is a 1 turn per inch screw.:eek:
Might have to buy a finer thread screw which means more $$$.

Frankenstein- not pretty- but hopefully effective. Will be nice to plug in some dowels for od turning and walk away- eh- or at least I think w/ my part-time helper "Frank"- LOL!

Gotta keep that "river of wood" going.

Somebody asked what the worst part of cuemaking is for them and somebody mentioned turning dowells- Hopefully not for me.

I plan to use a digitizer in the Z as well for shaft work.

"It's ALL BALL BEARINGS" ---- LOL!

id hook it to a dayton motor control about $65.00 we use them on our spray booth you turn down down to almost nothing

Mark, I did change the drive belt but the motor pully is the same one that came with the Hightower lathe.

There is a low speed adjustment inside the control box that will allow you to set the slow speed.
About 1 revolution per second (60 rpm) is where I set mine.

0 to 10,000

The one I have is fully adjustable... 0 to 10,000 RPM If you are interested, send me a PM. I'll send you full specs, photos.. etc. :smile:
 
Where can you buy these extras like pully and power supply or whatever its called to change AC to DC. And what do you do plug the unit into AC and then the motor into the unit? Does anyone have a web site of companys that sell these items?
 
Thanks Willee!
I just ordered one. I havn't done many wrapps, but I am in the process of building a small rap station with a dedicated rap machine.

Ebay is one source.
Electronic flea markets are another.
There are also industrial supply houses.

A lot of what cue makers use is ADAPTED equipment.
It is not all plug and play.
It needs some modification to get set up and working.

It is kinda like buying produce.
You dont buy it unless you or someone you know can cook it.
In other words, if you dont know beans about electronics and cant solder wires then you need to find someone else that can do it for you.

Is there a reversing switch built in?
