A Peach of a Homemade Parts Tumbler

[Chris] finds the average price of rock tumblers insulting. Almost as insulting, in fact, as prepackaged fruit salad made with Chinese peaches. While there may be little he can do about the peaches, he has given the finger to lapidary pricing by making his own tumbler on the very cheap.

Simply put, he drilled a hole in bottom of the peach vessel and then stuck a threaded rod through it. He held the rod in place with a nut and a washer. After securing the proper permits to source sand and water from his property, he put both in the jar along with some old nails that had paint and crud on them. [Chris] put the rod in the chuck of his drill and clamped the drill in his bench vise. Half an hour later, he had some nice, shiny nails. Make the jump to be amazed and entertained.

For those that are into reloading their own ammo you know that getting an efficient assembly line process figured out will make your sessions much more enjoyable and productive. [Msoejacobsk] knew that he could buy a case feeder for his system, but didn’t want to shell out two hundred bucks for it. After a bit of thought he was able to build this case feeder for around ten dollars.

The purpose of the rig is to orient each empty casing correctly and feed it to the reloading hardware. This is accomplished by first separating one casing at a time using this angled tumbler. The disc that makes up the floor has slots cut in it which are the size of one casing. When that slot gets to the highest point of its rotation there is an opening through which the casing falls. To ensure proper orientation a V-shaped piece of heavy wire has been place in the middle of the opening. This acts as a fulcrum, letting the heavier base pull the casing in that direction. You can see this happen in the clip after the break.
