I just sharpen the end of a K&S brass tube and punch the hole or piece I need.
You can sharpen to the inside, or outside edge, then drill a dowel or block of wood
to make a "T" handle. I have a whole series of them I keep in the drawer.

The fact that polyurethane resin is mostly oderless makes it deceptive in regards to the fumes it gives off. I learned years ago, that if I did casting work in the garage and did not ventilate, I would get a huge headache at the base of my scull and back of the head. I now vent the casting pot throu...

The issue I see, seems to be that the wheel and tire are one piece in some fashion. How will you separate the tire form the wheel to make your molds? http://static.rcgroups.com/forums/images/smilies/confused.gif If you calculate the cubic volume of your tires, you can then calculate the number of ou...

There are these printers based on the Makerbot. Like the makerbot, there is only one print head, and models need to be self supporting, or cut into sections that can be printed in one pass. Note the stair stepped terracing of some areas of demo models. The resolution at this price is still pretty co...

I think the car and the tie interceptor, pictured, are deceptive. The machine only has a single deposition head. So it can only print one material, starting from your base plate to the top of your model. The advanced machines use a support material that bridges gaps and spaces. If you are printing t...

With the barrel detached, I would be concerned with how thin the top of the gun body is, at the overhang where the gun barrel attaches. Thin is acutally more difficult to cast properly, than the bolt nubs. How thin is that shelf at 1/6th scale? With a Silicone RTV, the mold should be flexable enough...
