Helical Cutter Head

Sent both Byrd and Lux a question on Ridgid planer. Parts manuals on-line have the same link errors, so I suspect they are the same, one made by Tectron, the other by Emerson. ( JP06100 vs 06101)

Thumbnail cost. If a carbide edge lasts 10 times as long as steel, and it takes an hour to set up a set of knives, then a professional could never justify the labor for sharpening and setting up strait knives, let alone whatever the difference is in cost. A nick on a steel means slide it sideways, but probably replace soon. Carbide, just rotate. No full setup. Single carbide much cheaper than a blade. Still, it is the labor. I am retired, so my time is my own. At least on my jointer where I can do a decent sharpening job, sticking with steel for now. As I seem to nick a planer blade about every third or fourth time, if I upgrade my planer, it wil be helical.

Lux already replied. They said that all of this series use the same cutter head, as do some Grizzly and others. They provided two drawings but I have to go pull my machine apart to verify. There are small differences in the shaft dimensions.

Well, bit the bullet and ordered me a new head. Generic, sort of as two diameters. Mine is the smaller. Lux says just use the smaller for all and lower the outfeed. LUX was 4 rows, 28 cutters and cutters were $1 more, so went Shelix 30 cutters, 5 rows.

Anyway, you can get an inch-pound torque wrench cheap from Horrible Frieght for $20.

New head cost more than I paid for the machine ( used) but still, makes it what I want. I found out one pass of some glued up plywood and steel knives gone.

Probably obvious, but it just occurred to me the best way to prove your joiner setup is to do two planks on edge, book them and look for a gap. If outfeed is perfect, no gap. OK old timers, have a good laugh. :)

I think you'll be impressed with the overall cut quality and durability of the new cutters. I don't really consider this kind of upgrade a dollars for the machine vs the dollars for the cutter head a real comparison, you're making the machine much better than it was, and worth more, at least to you for what you can do with it.

I have the Helix on a 735 Dewalt. Love it. Someone said it drags the motor. In fact it does the opposite. Ive had mine 4 years now with no real issues. There are two diameters, one is smaller which allows easy change out. The OEM size which I opted for was a better decision for me. One, It's quieter. Second it cuts better than the smaller with less revolutions. Yes you will need to remove the end plate. I had mine changed out in about an hour and that included installing the knives. Yes you're putting a Helix on a box planer but you end up with a nice machine that performs well. No comparison with the standard knives.

I put the shelix cutter in my 735 planer, and liked it so much that I put one in my old Delta jointer. The head cost as much as the jointer did when I bought it, but what about a jointer goes bad if you take care of it? I have a "new machine" that cuts far better than it ever did from the factory, and likely I'll never need to replace the cutters based on how I use it. I went through a lot of knives though, and set up was a pain. I see too many positives with the change over to worry about how much it is vs cost of the tool new. I also don't see a huge difference in how much load either of the motors have, and the cuts are far smoother than knives, especially with figured wood that I frequently use.
I put it on my 735 too. No comparison with the standard knives. Turns a lunchbox into a pretty decent machine. actually relieves drag on the motor.

Grizzly DeWalt head had 2 sides cutters. At least the one I looked up.
Doing the analysis of planers and planer heads. Seems to be two common cutter bits, 14 and 15 mm, with the Unique German one Laguna uses, plus the cheaper baby Grizzly. ( Their planers use both 14 and 15 mm) Big differences in number of cutters with a matching price difference. I was concerned with proprietary cutters, but seems both common sizes have multiple sources so we should still get them 20 years hence.
