Not the same...a 3/0 is much smaller..takes or can be used with a # 70 drill bit and the #3 blade uses a # 60 bit ........Those are the bit sizes recommend by Flying Dutchman blades.
Tony, I have had the Seyco system for about a year now....Sometimes I love it and sometimes not so much!......It does a pretty good job and I guess my biggest complaint is if I do not get the seal just right when i change the bag it will blow out dust into the shop area......I get about a week out of a bag if I am not scrolling more than a few hrs each day....The knock out jar catches a lot before it gets to the bag....Not real loud but does add to the noise level as i have it mounted to the leg on the stand. I am not going to recommend that everyone run out and get one but i am glad i have it......I really like the in line switch that turns it on when i activate the foot pedal......Hope this helps and hope you enjoy it...Steve.
Don, I wish that I had a chance to sit in one of your classes two years ago when i took up scrolling......You cover a lot of the things that took a while to figure out on my own....Keep up the good work !
Paul, it is just a straight cut....That #1 Ultra reverse blade doesn't remove a lot of wood and it has an 1/8 backer that everything is glued to.......I guess it is a lot like inlay, the pant helps fill the small gap created by the blade.
