Easy To Use
The helical head does not get any better. I put this on my 54a jointer and it truly became a new piece of equipment I have read all the reviews for helical heads but they do not do it justice. The set up now is so on before with straight knives I would index for hours and finally just say good enough after installation I dialed in the machine in 20 minutes and the cut quality is unbelievable. There is one drawback when using a gear puller to remove the bearings off the old cutter head you need to use a puller with very thin teeth to fit in between the bearings and cutter head mine did not fit and how to buy a new one at an auto parts store take the cutter with you I had to try 4 different one before I found one that fit. All in all it was well worth it. I bought the helical for my dewalt planer at the same time a Byrd and the jointer one seems beefier the cutter and the knives there is a definate difference buy one and you won't be disappointed
