Been looking at LumberJocks for a few months now, just now finally got around to joining, this is my first post. I’m US-to-Argentina transplant, been living in Patagonia 12 years now. Last year while visiting my folks in the US, I finally bit the bullet and upgraded my router table and lathe. Bought a Nova DVR XP and a Porter Cable 7518/ Incra lift, neither of which I could find down here (nor anything remotely similar). Transport and customs were a beast, but the jump in quality is worth it.
1. Surge protection for lathe.
The DVR lathe has no problem switching voltage/frequency, but specifies that it needs a surge protector. However, that protector needs to be able to handle the high current the motor draws. Around here, what’s available is either a dinky thing designed for a computer, that won’t handle the draw, or a breaker-style voltage protector that will cut off if voltage goes above 252 or below 168. That seems to me to stray quite far from the 220 I ought to be getting. The DVR has delicate electronics, can they handle a voltage swing that large? I wrote to Teknatool a couple of weeks ago, no response. Might be because they aren’t licensed to deal in Argentina, or because they don’t read their email. Any thoughts appreciated, I’m anxious to get the thing started up, but given how much money and headache it took to get it down here, I don’t want to plug it in before I have it fully protected. Burning out that computer would be a killer.
2. Current drawn by PC7518
Since the router motor I got runs on 110, I have to run it with a step down 220-110 transformer. How much does it need to be rated to? The PC7518 is listed as a 15 amp motor, but the folks I went to buy a transformer from said to check what its maximum startup current draw is. If it runs 15 amps at 110, a 2000W transformer should be enough (110Vx15A=1650W). But they said if it draws lots of extra current on startup, I could burn out either the motor or the transformer in short order (might work a few times and then burn out.) Can’t find anywhere in the Porter Cable literature where it says anything about this, it’s always just listed as a 15 Amp motor. Any knowledge about this? If 15 amps is the max, then a 2000W transformer is fine, if more is necessary I’ll get it, but the jump to a 4000W version is considerably more expensive, and I’d rather avoid it if necessary.
Thanks so much! Once I get these 2 babies up and running, I’ll post them as finished projects, since I built a new router table and lathe stand from scratch for them. Keep up the good work and thanks for the help.
