New PM3520A, 2 questions.....
"Ron E." wrote in message om... Ordered my 3520A from Toolnut and am getting ready for its arrival. SNIP Question 2: I still have a Jet Mini so need fixtures with both 1" and 1 1/4" sizes. Should I just get an adaptor to make the PM 1", or would it be better to get new 1 1/4" inserts for my 2 chucks, and put an adaptor on the Mini to make it 1 1/4"? I'm leaning toward the latter even if it's a bit more money. ================================== The larger option is the way to go. You're paying a substantial amount to get a lathe that will handle a large piece of wood. Why would you want to reduce the capability by a large percent? Remember that the strength of the steel is roughly prpportional to the square of the diameter. 4/4 vs 5/4 inch, or 16 vs 25. There are other factors to consider in determining strength, but why do it that way? The adapter won't be much additional weight on the nose of the Mini, plus it will already be well balanced, so it would be like adding a Super Nova chuck where you originally had an older Nova chuck.

a PM tech who said my 20 amp service isn't enough. An electrician friend
says 20 amp is plenty. What do you say? The PM tech doesn't know what he's talking about. Your electrician friend does. Steve Sarasohn There are three kinds of people, those who can count and those who can't. |

I'm leaning toward the latter even if it's a bit more money. That's what I did. I bought a Jet 1442 last year and wanted to buy a chuck and some other accessories. I also plan to upgrade to a Woodfast, PM, or similar lathe in the not-too-distant future, so I chose to purchase a chuck and faceplates with 1 1/4" threads. I bought an adaptor from Jet to allow this to be used on my 1" spindle. Works like a charm. The adaptor was $65, but I'm guessing that one could be had for less. Max |

1. 20 amps is plenty - I run a 5 hp air compressor on a 20 amp (220)circuit
and that is a heck of a lot heavier load than any normal wood lathe - maybe some behemouth that turns a 96 inch slab might need more, but nothing in the 2 to 5 HP range. I am assuming here that you are talking 220V, if 110, current is doubled, of course. 2. I'd recommend that you have two sets of fixtures - the cost is nominal and you'll find that the large stuff doesn't work well on the small lathe, and you don't want the small stuff on the large lathe. Faceplates are cheap (see thread on cheap faceplates, or of course buy them from me ) and the only expensive fixture is a chuck. Once I got my larger lathe, I use my Nova Comet for pens and a few small items only. "Ron E." wrote in message om... Ordered my 3520A from Toolnut and am getting ready for its arrival. Question 1: Talked to a PM tech who said my 20 amp service isn't enough. Have to have minimum 25 amp, preferably 30 amp. Told him that my 3hp tablesaw ran fine on this sevice, and he indicated I was lucky I hadn't burned out the motor. An electrician friend says 20 amp is plenty. What do you say? Question 2: I still have a Jet Mini so need fixtures with both 1" and 1 1/4" sizes. Should I just get an adaptor to make the PM 1", or would it be better to get new 1 1/4" inserts for my 2 chucks, and put an adaptor on the Mini to make it 1 1/4"? I'm leaning toward the latter even if it's a bit more money. Thanks much. Ron |
