Seems like the topic of used 8” jointers is a popular one lately, so I’ll join in. There’s a Grizzly G4090 available, asking $800. It looks like I could get one of these new with shipping costs for $1100. Is it worth going used? The for sale ad says it’s wired up for 120v. Can you really get 3 HP on 120? I’d much rather run 240v. I don’t see any reference to using 120v in the current manual, so I wonder if the motor was changed out just to run 120v.

Don’t know what a G4090 is. Can’t see it on any site, grizzly or …

3hp is not available on 120… period.

490 is Grizzly’s current 8” jointer.
I have a Delta DJ-20 which is nearly identical to the 490. It runs a 1-1/2 hp motor, and has plenty of power for face jointing wide oak planks.

I wouldn’t do it, especially if they have done some kind of hack to run it on 120V power.

The G0490 is $950 on right now on sale. It’s a parallelogram table. The link is below. Is this the one?

Provided that it’s solid – flat tables, flat fence, good mechanicals – I would think you should try to get it for under $500 to be worth it.

A 240 volt motor will run on 120 albeit very poorly. If they wired it with a typical 110 cord they may have left one of the hot leads in the motor disconnected. This will cause the motor to run hot and lack torque under load. If they wired it to 110 by twisting the two hots on a 220 motor together and feeding them from a single 110 hot it will be the same, run hot and low torque. If used this way a good bit the motor can sustain serious damage to the windings, there are two sets of them in 220 motors as I understand it. If it’s been very lightly used in a hobby type situation it may not have done any harm. I’d start it up and see what it runs like and use your sense of smell to check the motor for a burnt smell. If it’s running hot or has a fried winding you will know it with just a whiff at the end of the motor the fan is mounted on, overheated copper and plastic sheathing have an unmistakeable smell. If it smells don’t buy it. Replacement motors run about $328.00. By the way definitely do some haggling on the price. Wouldn’t want to take all the fun out of buying used would you?

Thanks for the replies. I’ll try to find out more about it. Honestly, I wouldn’t want to pay more than $500. There’s also a Robland XSD 310 about an hour away (asking $1200)

Take a look at the Robland. It’s not super-refined but it has
capacity and that’s a fair price if it comes with the mortiser.
The mortiser is really cool.

I think your target price of $500 is more realistic for that jointer. $800 is too high…...

I gotta echo what everyone else is saying. The G0490 is a newer model (only meaning it hasn’t been replaced yet by another machine) so chances are good it isn’t too old. There are ways to hook up a 240v to run on 120, but it involves upsizing your supply wiring and splitting it across the two motor leads. Problem is, that the electric is no longer synchronous across opposing sine waves and you risk damaging the motor. Basically a similar situation that mantwi described. I would test it out before paying for it.

Second, WoodnDust is right. This new unit is on sale for $950 from Grizzly from now until July 4th. I don’t think giving any more than $500 is a deal at all, you might go as high as $600 if the unit is less than 3 years old, or so, and the cutterhead is still in good shape. Just my $.02.

It’s not really $950. I don’t know what you proximity is to a store, but for most of us it’s $1100.

I too would be worried about having it converted to run on 120V. While a 240V motor can be run on 120V, it would only have at most half the power and the contactor would have been altered as the transformer feeding the low voltage circuit is setup from the factory for 240V as is the motor. 3hp would be 18.65amps at 120V at 100% efficiency (not possible, ever) so if it’s being plugged into a 15A outlet there would be some undue strain on the circuit vs. what it’s made for.

I agree with Shawn RE those who say $500 tops. So what, Grizzly is selling it new for $950. I have to ASSUME all of these other folks are driving directly TO Grizzly and picking it up themselves. If NOT then the price is $1,100 and NOT $950.

$800 / $1,100 = 72.7%
THAT is a decent discount of 27.3%

FWIW, I bought a 2yr old G0593 8in Spiral head jointer for $700 that would have cost me $1,050 new at the time. I have now used it for 4yr and it has have more than paid for itself.

Pay $800 and save that money from being forced to buy a new one. So what if you only get 28yr of use out of it instead of 30yr…

I must say that HorizontalMike has a good point about figuring in the freight charges. Though when I look at purchasing used, I also look at the cost of traveling and loading/unloading to get the used equipment too.

There’s a 30 amp 110v format used for charging RVs. Some
people have there circuits in a garage.
