Silicone muffin maker
This is the first part to construction of the Actator.
I first measured the silicone form and using a cad program created a template for hole placement.
I used this speedbor bit 1-1/2" to machine the hole in the nylon block.
I used my cnc router to rourer a 1/8" grove around the perimeter. I also used the cnc router to make my punch holes for accurate placement of the bores. I set the depth of my drill press and bored the cylinders.
I clamped the 1/4" plate to the cylinder plate. Using the cardboard template I punched and drilled the scew holes. Next I counter sunk the screw hole to accept a Stainless socket head 6-32x3/4 " cap screw.
Next the silicone form was placed in the cylinder block, the top plate was installed and useing a small sharpend drill bit back I punched the hole through the silicone.
Here is the assembled unit . Time to complete 6 hours.
Here is a silicone sheet. I punched a small o ring with a sharpened copper pipe.
The first test valve. A tiny hole drilled in the bottom and one through the side.
The O-Ring is now install in the bottom of the valve body. the vent hole to the right is now visable.
I have 12 of these miniature solinoids to seal the o rings.
The assembled test vacuum valve working
I mounted the twelve on the valve plate.
