I recently bought a Rockwell RC-33 13" planer, the Delta model is 22-650. I posted on Sawmill Creek Classified a few months ago looking for an original knife setting jig, as this planer is very difficult to access the planer head to set the knives. I had several suggestions that did not work and had just about given up on finding a good off the shelf jig.
Yesterday I noticed a jig at Woodcraft. It is described as their small jig and costs $59.99. I bought one this morning and tried it this afternoon. Boy, am I impressed! This jig is well made, works as advertised and is easy to use. Note that this is for smaller planers, up to a 3" head. There are many brands that are available that are larger, to fit up to a 5" head. This is the first one I have seen for the small planer specifically. This jig is made in Taiwan, not PRC
For anyone familiar with the Rockwell RC-33, the motor sits on top. You take the metal chip shield off, tilt the motor and then take the chip deflector off. It only took me about 30 minutes to reset my knives.
Maybe I'm just a cheap date but I was very impressed and pleased! For anyone who owns one of these planers or other small planers this is a good deal.
