Topic tags/keywords: jointer grizzly

I’m looking to purchase a new grizzly 8” jointer. I would like to get a spiral cutterhead, but I have a spiral cutterhead planer, so I think i will save some money and not purchase the spiral cutterhead. The models I am looking at are:


The main differences are motor size (2 horse vs 3 horse), table size, and parallelogram bed adjustment vs. non-parallelogram bed adjustment.

My main concern is which model will give me two exactly (or as close as possible) perpendicular surfaces – I don’t think I need all the bells and whistles.

Hopefully I can get some input on this situation from the Lumberjocks who have some experience with these machines! Thanks

I have both a spiral head jointer and planner . I think having both makes a big difference well worth the price difference.

We just purchased the Grizzly 490X and it has the spiral head. So far so good, but it’s only 3 days old.

I guess my thought process on not getting the spiral cutterhead jointer was that I could just flip the piece over for one last pass on the planer after I had used the planer to create two parallel faces. Of course this could cause a problem if I don’t have enough stock to surface both sides, and I will not be able to use the spiral cutterhead on most edges. What do you think of this thought process? I guess my main concern is weather or not to get the parallelogram beds and the larger three horse motor.

I’ve got a related question… what is the difference between the parallelogram bed adjustment vs. non-parallelogram bed adjustment on the jointers? I looked at the Grizzly catalog and really don’t know what the difference is. What are the advantages?

What I meant was that you can face plane on a straight knife jointer, then run through the planer with spiral cutterhead to get parallel surfaces. Then (assuming you still have some material to remove) flip the piece over and run through the spiral cutterhead planer again to smooth up the other face. The two faces should remain perfectly flat and parallel.

I’ve got the G0490 with straight blades and am completely happy with it. It gives very smooth cuts with the straight blades. But obviously I can’t say how it performs with the spiral. As for the machine itself, the beds are truly flat and the three horse is awesome. This machine does not bog down. The extra longer infeed table is also a really great asset. Given the price I was very surprised and delighted with the heft, power and accuracy of this machine.

Randy, I have the GO490 with straight blades and it’s a good unit. I’m planning to retrofit it with a spiral cutterhead. I nicked up the blades on some dirty wood and it’s a pain to change the blades for one little nick. With the spiral head, you just find the buggered up insert and spin it. No setting the blades. You don’t even need to lower a table.
