While I was casting today, I thought that maybe some of the things I've done or made to make casting easier might be of interest to the group.
NOE large mould sprue plate grabber
Have not come up with a better name for this gizmo. This is intended for 4 and 5-cavity moulds where breaking the sprues is difficult by hand. But it would also be handy for even 2 and 3-cavity moulds for those with arthritis or other issues that won't them them cut the sprues with a gloved hand.
The grabber mounts to the benchtop, someplace convenient to where you are when you cast. Here is the grabber mounted to my bench. You can just see the base of my RCBS furnace in the upper left corner of the photo.
The idea is to cast the bullets then withdraw the mould from under the furnace and rest it in the grabber. When the last sprue frosts over, you simple push the mould hands to the left, cutting all the sprues quickly and easily. Here are the two steps.
I offered the design to NOE. Never heard back from them. If they ever offer it for sale, now you know where the idea came from. Yeah, I know, no sprues in the photos. I was done casting when I took the picks.
Mould Rest Roller
Anyone that uses aluminum moulds knows that sliding the mold over the round steel rod that serves as a rest under the RCBS furnaces is akin to dragging your fingernails down a blackboard. Aluminum is a far stretch from a glide metal. So, I had a short piece of steel hydrauic brake tubing in the scrap metal box that fit the rod perfectly. I machined another collar (you can buy them in hardware stores) from aluminum, slid the tubing on and then the other collar. Left a little room so the tubing would not bind. Now, the mould rolls effortlessly over the rest and there is no more gaulling of the bottom of the mould.
Here's the furnace showing the mould rest.
Here is a close-up showing the steel tubing roller. I would think that faucet or toilet feed pipe tubing would work as well.
I have another idea to improve the mould rest but have not made it yet. Might be tomorrow's therapy project.
Making Cardboard Wads
Charlie had suggested I use a thin wad behind the plain base bullet in my .38-55 when using 2400 smokeless powder. He said the Schuetzen guys use them as "gas checks". So, I thought I'd make a punch to produce correctly sized wads. What better to use to make the right size than the case it will be used with.
I took a damaged case and sharpened the neck. Then turned it around in the lathe and machined the rim flush with the OD of the case. I then drilled the primer hole out so I could put a rod into the case to push the wads out.
With the rim machined flush, the case will fit in the drill chuck of my drill press. Put the case in so it bottoms out in the chuck. Put a piece of wood on the table and clamp it. You need to clamp it because the punch will make a cut in the wood and make for cleaner cuts on the wads. I ran the drill at 1325 RPM which was just about perfect. Cut a new wad quickly and did not generate too much heat.
Here is the punch.
You have to move the wood base to a new position every so often because the cut in the wood gets too deep and pushes the wads too deep into the punch body. You can punch no more than 10 wads before you have to remove the punch and push out the wads. But the process goes pretty quickly. Here's a box of wads I made in a few minutes from some old tablet back carboard I had saved. I put them in a case and they stayed put. I had to blow them out by blowing thru the primer hole. I'm thinking of breach seating my High Wall so the case with have florist foam to keep the powder in place and this card wad over the foam to serve as the gas check.
