First problem that I see is that the tip of your nail has a faster velocity than points closer to the wall of the pipe so when the nail enters the sheet it will move through more material than when the nail is directly below the centerline. I think that your holes are going to be oblong...
I need to keep the cost down and keep it low tech for now; has to be something I can build in a small shop in a couple days. We even considered the hot needle machine despite to cost but it takes close to 4 months for delivery of a unit. We need something by the end of next week.
I think I'm...
DVD - I checked into it and the best thing for this material is hot needle perforation. A hollow puch system would also work but not ideal. Eventually i will end up buying a real machine (maybe 6 months out) but for now I really need to find a way to get orders out that is not too labor...
Even 3 feet per minute will do. I just tried it on a small scale using a 5" x 5" metal plate with nails through it (50 nails) and heating the back side of the plate with a torch. Imagine a branding iron to envision what the contraption looks like. There was no problem with residual smell or...
I put in a couple nails and heated the area of the nails with a torch and rolled it over the material. It made good holes and the roller did not damage the rubber. However, that was heating just a very small area.
My primary concern is how hot am I going to have to get the drum to transfer...
I need to melt holes in rubber sheets that are 20" wide by about 1/8" thick. The only way to punch the holes is with heat so they do not close back up. I know there are hot needle hole punch machines but I don't have $50,000 to buy one. So I'm considering building one myself.
This is how I plan...
