Using gasketed fixtures on a nested router12/3
I want to be able to hold down small and difficult to hardown hardwood parts on our nested router.
I would like to make dedicated gasketed fixtures to hold our standard size hardwood parts and doors. My current thinking is to make large fixtures with many standard parts and plug the holes on the parts not being cut.
I have two questions:
2.)For someone who does something like this what are the pitfalls and or what are best practices? How is locating the parts best done?
Any help is appreciated.
You can either add the fixture thickness to the material thickness or to the spoilboard thickness. Both have pros and cons.
I usually cut the inside of the shape right through the fixture, not just drill a hole or two.
Give each part a whack with a rubber hammer to make sure they're seated well.
You can run the fixtures on top of the spoilboard or after removal. If you have a grid table, you have many more options for positioning and holding smaller parts. For gasket, I use 1/8" x 1/4" gasket that I buy from All Star Adhesive. Cut the part shape offset from the part perimeter by .188 or so with an 1/8" bit and put the gasket in the groove. Leave about 1/16" above the fixture, it will compress into the slot and make a good seal. Offset that perimeter by 3/8" or so and cut a shallow pocket to act as a vacuum chamber. Inside that pocket drill vacuum access. If you are on the spoilboard, cut that pocket thru. Good luck.
Just did some small cutting boards
Looks like Christmas gifts!
