Howdy. Long time reader and finally decided to register and ask a question. Just a mere hobbyist here, who likes to make a lil sawdust when I’m not at my day job. My first post here at this site so try to bear with me…lol.

A few years ago I purchased a Grizzly go490 8” jointer, with the straight blade cutterhead. Always looking to upgrade or improve a tool I started reading up on the spiral and shelix cutterheads. Having gone through two of the Byrd shelix heads on my Dewalt 735 and sending both of them back due to deep scallops in the finish I opted for the Grizzly spiral head. Most everything Ive read on the Grizzly spiral head has been positive. Now as luck would have it my particular model of jointer is discontinued due to a change in manufacturing facility, and so is the spiral head from Grizzly. However….after a bit of searching I managed to find one on Amazon, the last one they had, part #T10126. Ordered it and couldn’t wait to check this thing out. Got off work one night and there the box was. This cutterhead was inside a flimsy wooden box, inside a much larger box, with literally one small sheet of packing paper. The cutterhead was rolling around loose in this wooden box and both rolled around the large box during shipping. The wooden box, obviously opened up before, is all busted up and the included tools are rolling around free and missing 3 of the 5 extra inserts. After raising sand with Amazon they assured me it was not used or damaged, yeah right, then credited me back 100.00 of the 425.00 price. Got around to cleaning all the goop off it today and sure nuff 16 of the cutters are nicked. Another one of these heads may be difficult if not impossible to find. So I have to decide if I want so send this thing back….just the way they sent it to me? Rotate the inserts, install it, and hope nothing else is wrong with it? Or possibly return it and get a Byrd shelix head and hope it works better on the jointer than it did on my planer? Opinions? Thanks in advance.

Well, I’d send it back…but then I have Byrd heads in both my jointer and planer and didn’t/don’t have the problem you did with them. But truthfully, the nicked cutters may not be all that important. I just rotated the cutters on my planer last year, after 7 years of fairly hard hobbyist use. I wasn’t sure it was needed, but they have such long life they will still probably outlive me.My point is, even with the cutters rotated one position, it will still give you a lot of service. You’ve had not-so-good experiences with Byrd so given the options you might want to keep it and just live with the way things are.

RailDude,

Poor packing, missing inserts, and then damaged inserts; sounds like the odds favor a defective part. While you could take a chance and install the $325 part and hope for the best I would be inclined to return the cutter head for a full refund. If you return it, I think making an effort to pack it in a manner that avoids damage is the best way to go. Otherwise, the part could be further damaged in shipping and/or the seller could point the finger at you for the nicked and missing inserts. You may want to take some photos before returning the part just in case they are needed later.

Whatever direction you go, it may be worthwhile to use a torque wrench and check that each insert is properly installed. If some inserts are not properly torqued down, poor performance could result.

Tough choice. I think I would call Amazon and ask for an exchange.

I have the same jointer & I bought the Byrd head from Grizzly. I don’t know what brand you have but if the packaging reflects the mentality of the manufacturer, well…..

BTW, current price at Grizzly is $335 but they are out of stock.

Worth a call to Grizzly I think. Good luck.

I have a G0593 8” w/spiral head. It is also discontinued due to new models coming out. The way I look at your situation is, that you WANT to make it work. Sending it back would not be “fixing” a discontinued model. Might I suggest rotating the cutters 90-degrees and see it that helps.

LONG TERM, I have found that rotating the cutters is important to do. I waited too long on the first set/side of the cutters and after rotating 90-degrees I discovered that indeed, the cutters were now ever so slightly worn (skinny now that the worn side is on the vertical). So I now have very slight lines on my jointed boards that require a light sanding. LESSON LEARNED – is that those 4-sided cutters are really only “good” when rotated 180-degrees. Trying to get too much mileage out of one side of the cutter and rotating only 90-degrees, is NOT worth it.

Truth be told, those jointing lines are very minor and will be sanded off when doing your final prep. Just my 2-cents worth…

I don’t have a spiral head but have been thinking of getting one.
I’m not sure I understand what your saying.
Aren’t the cutters staggered, in relation to each row?
I wouldn’t think a slight variance in width would have any effect, thinking the next staggered row would clean it up?
I must not be picturing it right?

Send it back.

I got a Byrd for my 8” jointer. Fantastic. Including packaging.

Scalloping would be more pronounced with a planer since it has a constant feed. Especially on the fastest speed. I don’t worry because planers and jointers aren’t finishing machines.

I have had great luck with the Shelix. I understand your experience was different, but whatever issues Shelix / Holbren was having have been addressed. In the end, a Shelix will give you a shear cut (true helical head), versus segmented cutterhead with square facing inserts for the Grizzly.

It might not matter for 9 boards out of 10, but I really don’t like tearout on expensive figured lumber. The Shelix delivers tearout-free cuts. I have heard Grizzly inserts are more expensive than Shelix inserts.

Good luck with it.

Thanks for the responses. Looking through the packaging again, there is a white sticker on the wooden box that was covered up by another shipping sticker. The one that was covered up says “PROBLEM SOLVE”. Yet another red flag in this ordeal.

EACH of the 40 cutters have four(4) sharp sides. And yes the 40 installed cutters are staggered, however I suspect that there is NO overlap of the cutters. I was very careful when rotating mine. I cleaned the head and each cutter as I went. Visually everything looked perfect, that is until I started jointing boards. Then the slight lines showed up. Not everywhere, but a few none the less.

After the cutters(through use) start to not perform as well as new, THEN you need a “new” cutting face on each of those 40-cutters. These 40 cutters(in four rows of 10) are marked with a “dot” so that the WW does not become confused when rotating each the cutters.

VERY IMPO0RTANT POINT: You need a torque wrench set to the specs in your manual when installing the cutters. Too loose or too tight could result in the failure of the screw/bolt that holds each cutter to the head. I would NOT want to be using the jointer when/if one of those failed!

Good luck to the OP in deciding what you want to do! Personally, I would rather FIX a small F__k-up rather than spend a long protracted time in limbo, ...waiting… just waiting…

Yes, overlap of cutters is what I meant, Thanks

Upon even closer inspection I found faint marks on the cutterhead shafts, indicating that this head has probably had bearings placed on it previously and used. All these issues are now on record with Amazon customer service and they have been very helpful. Too many red flags here to suit me so it went back today. For this kind of money there shouldn’t be so many issues with a supposedly new part. Guess I will give the Byrd shelix another shot and see. Thanks again for the responses.
