The DeWalt DW735 Thickness Planer is probably the best benchtop planer on the market today. However, the stock HSS (high-speed steel) planer knives don’t last very long. Replacement carbide knives are available from Infinity Tools and are a longer-lasting option (the set of carbide knives I am replacing in the video remained sharp for two years). Infinity Tools also offers their own HSS knives (which I have not used). I think that either of the options is better than the stock knives, but in the long run the best value is a Shelix (shear + helix) cutterhead from Byrd Tool Corp.
This video is the first of three (duration – 7:33). I start by discussing my motivations for the purchase of the Shelix cutterhead, then unpackage the cutterhead before beginning disassembly of the DeWalt planer to remove the stock, three-knife cutterhead. To guide me through the installation, I followed the Installation Manual (PDF) written by Byrd.
I hope that you find it informative and interesting. I am much more comfortable on camera now, as compared to the first video where I had to talk to the camera.
The next video shows the remainder of the disassembly and the installation of the new cutterhead. While you’re waiting for me to process Part II, you can read about how I installed a Shelix cutterhead in my Delta DJ-20 8″ Jointer three years ago.
