I really need some help. I am thinking of replacing my cutter head with a Shelix from Byrd tool. As I look at my planer this looks to be a very big and complicated job. Has anyone attempted this replacement and how did it go? Is there any information or videos on the internet about this.
Thanks for your help!!

There are videos on how to swap our cutters. The biggest pain is pulling the bearings. Make sure that you remove the carbine cutter inserts before installing them if they are currently on the new cutter head.

I have done this to my DC-380 and it is not too bad if you do routine machine maintenance. It took me one day to do. I would recommend that you either look up and order new bearings ahead of time, or have the time to take it apart and then get new bearings before putting it back together. Not only are the bearings cheap, but you don’t have to worry about bashing the ones in the planer when you take the head out.

I had a hard time with a few parts, but it was just a matter or either pulling harder, banging more, or just fiddling. Some of the bearings on the gearbox side are pressed into the cover that you will be taking off. This will make it seem like the cover is stuck, but in reality, it is the bearings that are pressed into sockets on the inside of the cover. You have to gently pry the cover off to release these bearings.

If I remember correctly, you don’t absolutely have to have bearing pullers, but you should get them anyway if you don’t have a set. The harbor Freight ones are a great deal and I can’t see ever needing better ones unless I start wrenching for a living everyday.

I did not bother removing all of the inserts as it would take hours to remove and re-install all of them. You can just wrap the head in thin cardboard like a cereal box and wear leather gloves and be fine. I did not cut myself on the head.

There are more tricks that I forget about, but it sure made the planer a new animal. I work with hardwoods for the most parts and the spiral head gives a smooth finish on these woods. It does leave a rougher finish on very soft woods like eastern white pine, so stick with straight knives if you will be finish planing that for the most parts. I would recommend it for sure. I just wish that I could afford to get a new spiral head for my new/old 24” Crescent planer.
