The Stovebolt Site Forums The Shop Area The Tool Chest Pic of VFD mounted on lathe (for Allen)

Here's a Link to the photo's I took of it Allen.

The whitish bracket in the first pic is a mounting bracket I hope to use for the control panel which is seen in the top of the tool box. I need to fab a bracket for it still.

It's kinda hard to make out since I painted it black but I had to weld the 2 motor mount brackets onto the back of the original Motor/Pulley plate. I drilled and tapped for mounting the electrical component box on the back, trying my best to move things out of the way of swarf and excess oil. The original motor sat in front and collected 'stuff'...
I had to weld a missing leg onto the belt tensioning/changing bracket to stiffen it up and keep it from popping out but that was minor.

While I was at it I replaced the original particle board top on the bench with the treadmills MDO cause... it's better in every way? But whoever built the stand knew what they were doing as it's framed up for support in all the right places. I have no idea if it was the guy who actually made the lathe (yeah it was made by a Mr. W.G. Hartman in Portland Oregon) or a later owner but for $475 delivered to my door (2 hrs one way), I'm not going to complain a bit.

Sorry
I have to ask a stupid question.
What is a VFD?

Well I was going for Variable Frenquency Drive

Won't make it true but saying outrageous things seems to be in vogue these days...
As in, My VFD is Yuuge!
Just sounds better than My treadmill motors bigger than yours.

Pretty slick Caso. Those motors are pretty stout. I was thinking you put it on a wood lathe not a metal lathe. Sounds like it's working fine! Thanks for posting.

Thanks for the definition.
I've been a machinist all my life and the acronym threw me.
We had one installed on and old Cadillac lathe, to power the motor and dial in RPM's. 24 inch chuck and a 16 foot bed. The old RPM's started about 3 and went to 28 in low range and then in high range it started at 78 to about 130 RPM.
To me it always had a big gap between high and low.
All the electronics did was adjust the sine wave from 60 cycles all the way down to zero.
Gave us better RPM selection, but I felt that under a load and too long of a wave, that it could damage the old motor.
If the motor is designed for that, it should work out fine.

I'm a regular Sargent Schultz at this but also like him... I'm ernest. Thanks YouTube

Allen, you could really throw some chips on a wood lathe with one of these. They sure flew all over when I tried my hand at turning some small bowls. Shop vac helped a little but I needed three I think.

Don, What were you turning on that thing Ship propeller shafts???
How much did that chuck weigh?

The nitty gritty of these motors is beyond my knowledge I just rationalize if it will hold up to a 300 lb gorilla walking at .5mph for 30min to an hour or two it'll work just fine especially if I use common sense and read the chips..
