Yay!!! I got the pic posted!
So the frame is way over built yes! The top and bottem are removable plates(1/2") and ther are holes on all four sides. So far each end has one hole and one side has 8 holes spaced out 1/2" apart and the other has 5 holes spaced out 3/4" apart. The holes are 1/8" for sprue formers used in jewelry making. Now I have not made anything in the mold yet so, Im not shure about plugging the holes yet. I dont know if the sprue rods will just stay in place under the pressure or if I will have to either tap each 1/8" hole or tap a hole on either side of each series to screw a block over each series to hold all the rods in under the pressure. The scrap of aluminum I bought was the smallest they had in 1 1/4 thick and was actually big enough to make 2 frames out of, I cut it in half and it was still bigger than needed so rather than cut it I just chose to leave the sides thick, I think one side is 1.5" and the other is about 2". The block was milled out with a crappY extruded aluminum x/y table and an old 4 flute mill that some gave to me. I first cut out the hole in the center and then milled it roughly square. Its rougher than it looks but turned out well I thought. I determined the size by drawing 1/4 of a 12" circle(silicone 12" unvulcanized disc) then figure out how large I could make it and what shape I wanted. So It is made to mold 2 rows of small jigs heads at the same time with a row of 8 small heads(aprox 1/100th ice jigs) on one side and a row of 5 larger(aprox up to about 1/8 oz). But can obviously mold a single row or larger lures from the ends. I made a large and a smaller mold frame and should be able to get roughly 4 large and 4 small molds out of one disc but the small mold will probably have corner spilices to have the silicone fill the inside but is supposed to bond and be one piece. I also left room for small lock nuts in the corners to allign the molds.

It took alot longer than I thought to to mill out and layout and drill all the holes. Not knowing anything about milling a 2 flute bit didnt work worth anything at 1000 rpm but the 4 flute did fine. I used automatic trans fluid to lube and keep the chips clear.

This was a project to be able to make masters and play with designs with out using a whole spincasting silicone disk up. I will have more pics tward the end of the year with 12" mold frame and homemade spincaster.
