Rewiring a Grizzly jointer for 110V
In the December issue of Fine Woodworking, the Grizzly G0500 was the author’s choice of 8″ jointers. It’s now been replaced by model no. G0586 (and is significantly less expensive). I’d like to buy one, but my garage only has 110V service.
Here’s an excerpt from an email Grizzly sent me:
“The G0586 is shipped with the motor prewired for 220V usage and a 220V switch. It can be rewired to run on a 110V circuit. This would require rewiring of the motor and replacing the switch with a 110V switch unit.”
Has anyone done this, and what does it involve?

I've rewired my machines from 110V to 220V. It was as simple as opening up a little panel and attaching wires differently. The tools start up much smoother now.
Since you are going the other way though I have a word of caution. The load may be too much, and you'll trip the breaker. It looks to me that the G0586 is set for 15 Amps at 220V, so to go to 110V you'd be doubling the amps to 30! Most 110 circuits are only 20 15 Amps, so you trip the breaker every time.
Thanks, guys. You know, I had wondered about that. My breaker can't even handle both my space heaters at the same time. I'll look for a good 1 1/2 hp jointer.“An expert is someone who has made all the mistakes which can be made in a very narrow field.â€

Can't you wire 220 into your garage? It's not that expensive, and I think that you will encounter this problem again if you add more equipment (especially duct collectors and the like).Glaucon

I'll get a quote. The second choice would be a Delta 37-380, but there's almost a $300 price difference. I should probably get the garage rewired, you're right, because I also plan to add a planer and a bandsaw in the next six months.Thanks.“An expert is someone who has made all the mistakes which can be made in a very narrow field.â€

I agree it's an issue that could very well continue to hound you. 220 opens up alot of possibilities, and helps even the 110v motors if rewired to 220v (easy to do). I ran a 220v line from the house to the garage myself for about $25...just tapped off an unused drier line.
Don't do any electrical yourself if you're not comfortable. I guess I'd rather see you spend that $300 price difference toward 220v than a shinier machine.
I found myslef in a similar situation and went for a smaller 6" jointer. Even with that you may trip a breaker if you have a space heater on. I upgraded to 220V when it became clear that I would not be able to heat my garage, or run dust collection I decided to upgrade the power.
I had an electrician come in and do all the work. He ran a 60Amp subpanel, three 220V circuits and an extra 110V circuit. All surface mounted in armoured cables. Total cost was about $1000 (Canadian). I had him rewire my machines while he was there as well.
I can now run a dust collector, jointer, and heater without any problems. I don't expect to be drawing to much more power than that any time soon. It is one shop upgrade that I highly recommend.
I think you were wise to bite the bullet and rewire... this topic comes up from time to time, and I can't recall anyone regretting upgrading their electrical service. Even when it runs from 500 to 1,000 USD, it just removes so many future headaches.Glaucon

Putting two 115 hots of the opposite phase gives 230 V supply. Two hots of the same phase of cource gives zero volt.
For many years I simply connect the hots from two such outlets to get 230V. Two hots going into an electrical box with a 230v outlet. The two circuit breakers are simply in series. This gives me 230v 15 Amp. You (and your family member) need to be sure not to overload either 115 v outlet with 115 loads however. You cannot run a router on either when you are using this setup. My kids are grown and so won't interfere and I control my destiny. Also, do not have all the light sources of you shop connected to any just one of such 115 circuits. In general have dispersed sources of lights so that if there is a trip your shop won't be totally dark.
This is a portable 230V setup that let me use my welder anywhere in my house where there are two 115 V opposite phase outlets. I can always use just one extension cord to get to one outlet of the opposite phase somewhere in my house.
There were also two adjacent blanks in my circuit box. So I finally fished out the wire and wired my 230 about three years ago. Two adajcent slots in the circuit box, for circuit breakers, are of opposite phase.
Don't get yourself killed if you know little about electricity, however. I just want people to know that 230 v is not difficult as long as the amp is under the limit of the circuit breaker, 15 amps typically.

A caution is, combining opposite-phase 110 circuits to make 220 won't work well if your 110 circuits are GFI'd, as garage and some other circuits likely are.
Yes, no GFI circuits.
But in my garage there are several circuits. One for the gas furance, one for the sprinkers, one for garage door opener. None use more than an amp or two. These don't have GFI.
Yes, make sure that the light source are from different circuits. If someone plug in a 12-amp vaccum cleaner or a hair dryer, the worse would be a trip of the machine. Never use a circuit breaker rated higher to avoid a trip.
Hi Bill - Buster2000 is right on the money. IMO you'd be better off pursuing a machine with a 1-1/2hp motor or smaller. Otherwise you'll be requiring the shop.
