Recently I purchased a Byrd head for my DJ-20 from Grizzly. It arrived this past week, but I’ve yet to install. My decision was somewhat based on a friend’s Byrd head for his DJ-20, purchased a few years ago (not from Grizzly). The first thing I noticed out of the box was a lot of drilled holes for balancing. I know bandsaw wheels, pulleys, etc., are balanced by drilling holes, but this was ridiculous. Looks like whoever did the balancing (if it’s truly balanced) was drunk. My friend’s Byrd has no drill holes, but then again, neither does the original DJ-20 head. Aside from the aesthetics of holes all over the head, the rows of inserts are different. His has 9 inserts per row. I think the inserts are a bit smaller too, but not sure. When looking at the Byrd Tool web site, they make no mention of insert count. This makes me question whether Byrd has a “cheaper” version they make for Grizzly. Does anyone else have an 8” jointer with Byrd head that was not purchased from Grizzly?

One more detail I rememberd the cutting circle was over 3 inches maybe 3 1/2. So that maybe why there’s more inserts.

I think (keyword, think….not based on fact) they have made changes to the design over the years, likely for a little cost control among other things. That said, I have the Grizzly sold Byrd head in both my jointer and planer. The jointer is an 8” Jet, and it has 5 rows of 8 inserts. My Jointer head is about 6 years old, my planer (and I don’t remember how many inserts it has…but it was less than I thought) head is about 7 years old. I do know when I bought mine they had the same part number as the ones sold by Byrd. I guess you could call them and ask, they’ve always been very helpful the times I’ve called.

I checked my friends and it has 6 rows. A total of 4 rows of 9 inserts and 2 rows of 8 inserts, totaling 52 inserts on the head. That’s a fair number more than the 40 that are on mine. I didn’t measure the diameter, but appeared about the same. Seems like the more inserts, the better chance of a smoother cut.

Thought this looked like an afterthought too. One insert out of 40 that’s set an an odd angle. Looks like they miscalculated! Note the balancing holes. I’m surprised there aren’t a couple screws in some to get the weight back.

Fred, does one of the rows on your have this same insert?

The purpose of the holes is to remove weight. If you add the weight back, it wouldn’t be balanced.

If I’m not mistaken that last insert is turned so you can still use the jointer to cut rabbets.

hmmm. Something I’ve never done, and probably would never do on the jointer, but that does make sense.

The didn’t miscalculate something like that is an obvious design. Call Byrd and ask them.

Just install it (easy as pie) you’ll be very happy with it.

I’m hard to please! (haha). I did help friend install his, which was pretty easy. The head is removed from jointer a lot easier than I expected. We left bearings on original head and pressed new on Byrd. This brings me to another question….how does Byrd pre-install bearings when the pulley side is in the block with a inner circlip on the block? The only bearing they could install would be the outer bearing. Comments?

I would assume that no one bothered to balance your friend’s Byrd while in your case someone was very thorough.
And size of the balancing holes are opposite proportional to the diameter they are drilled at. It is not made to look pretty, it is for cutting wood.

Not sure I’d make that assumption about my friend’s Byrd not being balanced. It runs pretty smooth to not be balanced. Maybe he was just lucky. As I said in the initial post, I know it’s aesthetics, but it almost appeared that the person that balanced the head was making corrections to the other corrections, if you know what I mean. Kind of like the old lead weights on your tire wheel. If you saw 10 weights on your wheel after getting new tires, you may be suspicious! and yes, that’s an exaggeration! Can’t it cut wood and be pretty?

The problem with keeping it pretty is then it would be pretty expensive. You would be shelling out countless rolls of pretty pennies.
