  1. that is what I normally do and it work good enough for me.
  2. I tried one and without the hook the pic is not correct to use to draw the hook. I traced the drawing, guessed the diameter, and as you can see the pic or the dimension in the pic are wrong. A lot of times this works for me but I always have the actual hook.
  3. I agree completly with Fatman. I have had that problem before and it is usually because of too much talc in the molds. it also happend with some very old powder paint. the vinagar did fix the problem for me. I mixed he vinagar with half water, heated the water to 180F and then rinsed in clear water.
  4. this is what I did, I don't have any pics yet. I took a pressure cooker, bought some door seal at auto parts store that had sticky tape on it and I stuck it to the top edge of the pressure cooker. then I had a piece of 1/4" poly carbonate cut round to fit the top of the pressure cooker. then I bought at harbor freight an air conditioner vacuum pump, https://www.harborfreight.com/air-vacuum-pump-with-r134a-and-r12-connectors-96677.html took out the venturi air pump drilled a hole in the center of the poly, put pipe threads in to attach the air vacuum pump and waaalaaa. I used it to d
  5. In a lot of places it is not open year round.
  6. anyone wanting to mass produce needs to read this (smallmouthaholic) and understand this. The only thing I would add to this is: take out of your vocabulary the words "It should work" because what looks like will work doesn't look or work the same in production. I use to be young and dumb, I'm not young anymore.
  7. I don't know of an easy way to learn, just trial and error. there is some free software out there, you will have to be diligent in your quest. I have never found a cheap scanning service, my quote was $500 what have you done so far?
  8. very soothing. great idea too. I like the fan with 1 blade removed. so no porous membrane in the bottom?
  9. I cataloged all mine in a spreadsheet, printed out a list, had them closed on shelves with the number on the end of the wood handle showing so I could find it on my list, then looked for the number of handle. I had the shelves with numbers so I had location numbers on my list and still couldn't find what I was looking for when I needed a mold. so I put them on peg board .The pic of my molds takes up a lot of room but at least if can find what I am looking for. and while looking for a mold i'll see one that i forgot i had, so that is helpful.
  10. silicone does not need a mold release, because silicone does not stick to anything. If i was making a mold out of bondo i would use Vaseline as a mold release maybe thin it with mineral spirits. make sure what you copy, your jig, dosen't have nay undercuts or you won't get it out of the bondo mold. IF you make a mold out of RTV silicone I would use that to pour my jigs. the foundry thing sounds complicated to me. after re-reading you post you want to copy the molds not the jig. How are you going to make multiple cavities? I would say that no response means not
  11. does mustad have one? Mustad 60 degree cross eye 2x strong Needle Pt. Mustad 32796 but I don't think is is 2x strong.
