Thought I would post a photo of my latest project, a case annealer. I copied the idea from ones on the internet inspired by Skip the Australian post of many years ago. I made mine with a cogged drive belt to synchronize the feed drum and the annealer pan, using only 1 drive motor. Used parts from a supplier of DIY parts for 3D printers as main supplier of parts. Started with 3:1 drive ratio and 610mm belt, but was too big for the box I got so changed to 2:1 drive, shortened the length and used a 400mm belt, which worked out well. At this time, I am awaiting the arrival of the torch hose, all else is finished. It cycles well.

Sorry to be 3 years in replying but I bought mine from CH.

I just whipped this up for tumbling primer cups, but can be used for any small batch tumbling

Section of PVC sewer pipe or something similar. Cut some scrap 2x lumber and screwed in from the outside.

Added a piece of cardboard and stapled down

Heated a vitamin bottle and formed squareish sides.

Insert bottle, fill with media and tumble away!

Cardboard can easily be changed anytime.

I like your ingenuity - but what is the purpose of the bottle? Couldn't you accomplish the same with ends for the PVC?

The idea is to make a tiny tumbling chamber. This goes in a Lyman Cyclone tumbler base. I should have explained that part better. I can fit 10lb of stainless media and a thousand or more 9mm cases, but I frequently want to do a small batch of something so I’m not having to sort so much media.
Two, too simple tricks: If you decap a case that's a scarce one, and the skirt of the primer stays in the pocket, pick out a worn allen wrench, about 1/8 inch, cut off the short right angle, and grind a 45 degree angle to a sharp point, and put a handle on the blunt end. You can pry the primer skirt out with this gizmo.
Changing primer punches on a lot of presses is a pain. The large primer punch does pretty well with small primers. You do have to pay attention to get by with this. An old buddy whose press I bought at his estate sale did this for years. I do it now.
GONRA sez small "Pill Bottle" tumbling like you guy describe above,
is useful for thoroughly mixing small primer mix batches.
Just use a 100 ft. extension cord in back yard in case it blows up.
Dry primer mix really looks nice and uniform!
NO CLUMPS!
Just a simple project i've been putting off for a long time.

Finally got around to making a wrench for the new Lee die locknuts. Don't know what Lee was thinking when they made that cheezy short plastic wrench but even hand tight the nuts usually need more oomph.

Boy would I like one of those! That breechblock little plastic wrench Lee supplies is a pain in the rear end! Not having the necessary tools and equipment to make one I’ve been relegated to tape the jaws up on a pair of channel locks and being very very very careful! Really nice tool! I bet you could sell them in a heartbeat! Obviously depending on the cost
I've no idea what Lee uses, but this is the tool that they should be supplying, a C-spanner (or "hook wrench", in 'Merkin):

This example is sold by, of all places, Walmart. For what, I've no idea. They're very common in the machine shop trade.
The one you built is the Rolls-Royce of spanners. Well done!
