Helix Cutter-Heads
I've spent the last few days installing the spiral/helical cutter heads in my Carbatec 6 inch long bed jointer and my 15 inch planer.
It was not nearly as straight forward as it was made out to be. With the jointer it required a complete strip down to allow the infeed and outfeed beds to be separated sufficiently to get the assembled cutter-head and bearing block to be installed and bolted in place. It was promoted as a job that could be done in two to three hours. It took me almost two days. The `15 inch planer had a good set of instructions, or so I thought, but then found out that there were some critical information that had been missed out. There was also a good video from the Canadian "Grizzly" company showing how to do the change but they made it look so simple that it was unreal. In the event it took me about 8 hours to change the cutter head in this machine. The main bearing on the cutter-head shaft would not move and I think that I have broken my pneumatic bearing puller. I went down to the local SKF bearing shop and replaced it for a mere $14.50.
One thing that was not stated in any instruction was that there should be a packet of Band-Aids handy at all times. Even though I had the cutters covered with cardboard until they were installed there were corners sticking out and the tips of just about every finger was nicked at some time.
The initial test results are that the cutters are certainly quieter than the straight blades and they do seem to limit the tear out on cross grained wood, (Tasmanian Blackwood). The surface is definitely smoother than the blades ever got it and it comes out the machine needing only limited sanding.
We shall see if this as a good move as time goes on.Jim Grant

They make it look easy on the Grizzly videos. I wasn't game. I sold my old thicknesser and bought a new one. Cost more, but none of the frustration.
i hope you get good results and are pleased. I'm so impressed with the finish my get.
cheers,

I too got covered in small cuts from the installation process. Quite a pain they were. Although mine was installed on a homemade jointer so I can not say I shared your frustration with retro fitting. Sorry to hear about that

I wore gloves...
2-3 hours is a bit ambitious, I think the jointer (SCM F410) swap took me 6-8 hours spread over 2 days (sent the head out to have the bearings pressed)
The thicknesser (SCM S63) took much longer, but there was much more to do. We sent the feed roller segments and anti-kickback fingers away to be reground as 40+ years of wear had taken it's toll on what used to be sharp edges...
You won't regret it, helical heads are pretty much the greatest invention since carbide tipped saws.

I done both of my machines (8" buzzer and 15" thiknesser - Carbatecs) a couple of years ago. It was all pretty straight forward and didn't have to touch the in feed and out feed beds of the buzzer. It all worked a treat.
