Ridged Joiner model JP0610 helical head replacement

I replaced my jointer knives with a helical head. No instructions so we figured it as we went. It is a pretty easy job and most should be able to do this with no major problems. I am not sponsored by them but have been asked were I purchased this. This is a Lux Cut III Head that I purchased through . They are very helpful in getting you the correct head for your jointer or planer.
