Thread: Home made Annealing machine

So made my own annealing machine that I copped off a link on the stalking directory here in the uk.

I modified it some from that design. Ive tried to find the links for NZ but in some cases had no joy.

This will save you having to solder the wires. I started with the switch on the back turned way down and then increased it till I got the motor to run. Easy to wire and use.

Speed controller. Again easy to wire up.

You only need a small amount of this. 60cm diameter / length of the cartridge that you want to anneal.

I just use my plumbing blow torch. Sure you guys can by the same in NZ. Someone I'm sure will have a link and can maybe even get the NZ links for the above items.

So to the build.

I used 18mm plywood for the front and base. But I'm sure that you could get away with a smaller. As you will see from the photos I did cover the area where the heat is with a thin metal sheet for protection.

I cut from the plywood sheet a 300mm/300mm at 22.5 degree on the bottom and top. One off cut I used for the base and the other to mount the motor on. That way the shaft lines up with the front face.

(Don't do what I did and mount the motor to one side. Id place it more centre. Mines 80mm from the Left hand edge. I'd go 100mm)
The wiring is very easy its just connect the + & - the same goes for the speed control and

Next get your 60mm rod bars. If you have a mate with a mill then he can cut and drill them. Id even have him tap and drill the centrers so that you can just screw in a M8 bolt. One for each. If you don't have this option then drill a small hole straight through the centre an increase it to the 8mm diameter. For the shell holder hole I did the same and just increased the size till I got up near the edge then opened it up with a hacksaw and finished them off with a file.

With the motor in place and the bottom wheel on I then figured out where to best place was for the top wheel.
I placed the two sprockets with the belt and then drilled the second hole for the top wheel.

You will need to add a fixing pin so that the cartridge turns as the wheel rotates. 11oclock is about right. The only other pit fall is the cartridge stopper on the top wheel. This I needed to stop the cartridges from riding up and over the top.

Last thing was a 10mm pipe holder to hold the torch in place.

To find out the best speed versus flame. I went in the garage turned off the lights and ran a few old ones through it. As soon as the glow in the dark you have the right speed. A small metal tray is best to collect the spend brass. Not plastic...... they seem to like to stick to that for some reason:
