Hi all,

I’m in a bit of a pickle. In a spontaneous move yesterday I have a DJ-20 in the back of my truck and a friend looking to take over my Star Tools/Elron jointer.

The Delta’s beds are a little longer and it’s got the parallelogram setup versus the typical triangular setup. Those can be considered improvements, I suppose. But I’m REALLY nervous about the power. The Star’s got a 2HP/11A motor and the Delta’s only got an 1.5HP/8.5A motor. Actually, the power switch box on the Star lists those specs, which is what I wired it for. I haven’t found a label on the motor yet to confirm. I suppose I could try to monitor the amp draw when running under a load. Is the power really that important for the jointer? I’ve never had a power problem with mine, but then maybe that’s because it’s 2HP?

My buddy paid half of the cost of the Delta, making it a $400 “upgrade” for me. But is it really an upgrade? Am I making the right move???

Just buy a 2hp motor, or step up to a 3hp Leeson and get some!

How often do you do more than joint the edge of a board on the jointer? A friend asked me this question
when I was questioning the motor horsepower, the answer was that is all I use it for . If you are going
to use it to plane 8” boards, then you might need more power.

when you burn it then get more ponies. I really doubt it will be a problem.

1.5 hp is fine for an 8” jointer unless you’re really hogging off
stock, like in rabbeting. I suppose as the knives get real dull
you might get a smoother cut with more power.

I mostly use a jointer as a finesse tool and take lighter cuts.
As a practical matter, a hogging approach to surface
jointing eliminates a lot of wood and tends to lead
to undesired thickness loss from end tapering in many boards.

Thanks for feedback.

I went with the swap. I can’t believe I have to go buy a smaller (amps) receptacle for my “new” jointer. It just feels weird. I actually use my jointer quite a bit for both flat and edge jointing. I’ve never had an issue with the 2 HP motor, so I’m crossing my fingers!

Now if I can find (and afford) a bigger planer and a drum sander …

Why would you replace the receptacle? Does the delta have a different plug?

That’s correct. I had a 20A twist lock plug on the Star and the Delta’s got the typical horizontal plugs (15A).

Just put a 20 A twist lock on the Star.

Oh, that would be not be advisable. One should never put a higher rated plug on wiring that can’t support that current. Sure I would know what’s going on, and as unlikely as it is, someone could someday throw a 2HP motor in it and if they didn’t upgrade the cord and other wiring a fire could start.

You got a great deal, the Delta will be just fine. By the way how did you like the Enlon? I’m going to upgrade my jointer myself in the future and wonder if I should add it to my list of possibilities.

That machine worked great for me. The fence was bowed, but I never got around to getting it reground. It wasn’t really an issue for me. I got lucky with mine, buying from a older gentleman who used it lightly in his condo basement. So it was basically brand new. Amazingly someone listed that same machine this morning on CL for $295! I actually emailed the guy, telling him that was too low!

Not wanting to argue with you, but why do you suppose that a 240V/20A receptacle will also accept a 240V/15A plug?

Regardless, enjoy your jointer….it’s a dandy.

Don’t worry about arguing, I’m always trying to learn, and I’m certainly not an authority. I’m just going by what I’ve learned so far in a confusing area.

I’m trying to understand your question. Hopefully I got it right. What I want to avoid is putting a receptacle that’s marked and rated for 20A on a chord that can’t handle 20 amps. It’s similar to putting a 20A breaker on 14 gauge wire. It’s the “chain” you need to protect. So it’s fine to plug a machine that draws 5A into 20A circuit because its plug, cord and circuitry is all rated for 5A. The potential of the circuit it’s plugged into isn’t the issue. Now, if you took that plug off and replaced it with a 20A plug. Someone could look at it and think the machine can handle 20A. They could swap out the motor with, say a 10A motor and BAM … the cord would fry.

I’m sure I’m not wording this as well as someone smarter than me could!

I do face jointing frequently on my 6” Griz jointer that has a 1hp motor….while there have been many times I wished it was 8” wide (or wider), I’ve never for a moment felt it was underpowered. The 1-1/2hp Delta motor should be just fine on an 8”....I wouldn’t even consider getting a bigger motor until it’s clear that you need one.

What I’m trying to say is that plugging the 15A Delta into the 20 amp circuit that used to run the Star is perfectly acceptable and safe. Putting the 20A plug onto the Delta machine is not a problem either. My understanding is the wall circuit is set up for the Star (20 amps, I guess). That same circuit is perfectly acceptable for smaller loads like the Delta. You don’t need a lighter service receptacle, but like I said enjoy!
