read alot of that horsepower vs. amps math .. Geez ,, They even have a name for playing with the numbers .. "Puffing".. There is alot of inefficiency with a single phase motor converting electricity to power, so any numbers are suspect . Bill your numbers are more realistic .. Pete thanks for the facts, I learned alot . Slip I think your right .. I thought a Jet was out of my present wallet but its in the ball park . Just have to sell a few more of wifes things on ebay . I have an idea ,,but wich model number Jet .. Thanks all .. Beware of "Puffing" ..

FWIW,

Amps is a current rating. Power is a measured in watts or Hp.

Amps X Volts = Watts

(this shows why a 220 volt line (vs 110) with the same amp motor produces twice the power)

746 watts = 1 Hp

So,

15 amps X 110 = 1650 watts / 746 = 2.21 Hp

4 amps X 110 = 440 /746 = .59 Hp

I bet there is a typo someplace. Are each 110 or is one 220 volt?
However, a lot of time you see "peak Hp"...which inflates the value and makes a better sales pitch.

Hp - amps for 120v 1phase
.5hp - 4.2amp
.75hp - 6.3amps
1hp - 8.3amps
1.5hp - 12.5amps
2hp - 16.7amps

same size motor @ 240v
.5hp - 2.1amp
.75hp - 3.1amps
1hp - 4.2amps
1.5hp - 6.2amps
2hp - 8.3amps

This is from my chart that I use when sizing circuits

Yes, I am a commercial electrician...

I work with this crap every day.. so I'll make it simple...

HP is directly related to the strength of the motor, the larger the motor the less strain, but larger motors also use more energy which is the amps everyone is talking about, most modern motors are energy effecient,and amp problems most often occur when dealing with blower units and fans, not motors driving pumps or a reduction unit ( lathe head stock)...the only thing you need to concern yourself with amp wise, is the amount of items on that particular circuit...... each item draws a specific amount of current (amps) too much and the breaker will pop( it's like trying to get too much water through a small tube or hose, it has it's physical limits)...in most cases your shop vac will draw more current than your midi lathe...

I have had a turn crafter for several years now, I love it,last year I converted it to variable speed, I love that too, the only thing I'll say about the VS, is that on occasion, you need to blow the dust out of the motor brushes or the motor speed becomes erratic.. not a big deal, just routine maintenance..no biggie for me seeing that is how I make my living...

Speaking of all this, I'm in the process of replacing bearing in a coolant pump on a hardinge lathe right now, the bearings are causing the motor to over heat and over amping the circuit and trip the relay...

Ed; I have a Jet. A friend has a TurncrafterPro. The TurncrafterPro is the best bang for the buck. Better warrantee as well. Parts available right from PSI. You just can't go wrong with the TCP.

i have a spare motor Tagger

Brand new too... trade -for a plug

one speed though

Tagger · 03-11-2009, 09:11 AM

Just listed 2 items on epay (not Plugs).. I guess I'm serious about this .. I have to stimulate the economy so I go back to work .. Raven ... motor ?,, I didn't get a mine lathe yet .. I bet I have the biggest lathes on here and work in the smallest space .. nutso ..

Raven · 03-11-2009, 09:18 AM

just trying to help, Ed

speaking of work....

desperate times require out of the box thinking

S-B marina .......... here we come...

i'd bet the places available now are out there

just a thought.... with more power - as a group

we even have S-B lawyers

Good idea, gold is bringing a good price.

Just got done setting it up .. I ebayed a large BM black darter ,, A mint Point Jude Mackerel Cutlass ,,3 Sorby wood lathe tools .. A mint 6500cs Mag Elite and a Penn 710Z and some other small stuff (wifes) for this lathe .. one thing I learned ,, Now is not the time to sell off your plug collection on ebay .. plug market slid .. Amazon was the best deal with the free shipping ..This little lathe is fast ..

So are we going to start calling you "fast Eddie"

VTBasser · 04-01-2009, 10:36 PM

Good pick!

I have the same one and love it.

Mugz · 04-02-2009, 08:10 AM

Bought the same a month ago......love it. It's a cadillac compared to what I was using.
