I have tried. The problem with table top induction stoves is they use Litz wire coil and it does not stand up to temps above 400F so it must be protected. You may put a layer of stove insulation...

Correct OAL depends on the bullet nose shape for barrels with short freebore.

Can you notice how same OAL is wrong for those different nose shapes?

The result is something like...

I first wet tumble all 9mm-looking brass without any sorting.
Then I lube and push them all through bulge buster like this https://www.youtube.com/watch?v=DQR9IghtSy4 using 9mm-Mak FCD

flybyjohn,

In my understanding such full length radial shear can happen only from radial torque and that can occur only by means of excessive acceleration. Acceleration is directly proportional to...

If you are using some 2-component powder then you may try wetting the boolits with compatible catalyst or resin. This would work as sticking agent and later would react and become part of the...

It's not that bad. Sure, there are products that are more like toys, but there are some from china that are very usable. Just have to understand how IRT works and respect D/S optical ratio to get the...

Thanks for your kind words. The paint I used was stove paint spray. I left the area of the mold placement unpainted for better heat transfer.

When I was playing around with electrolysis I quickly...

As many Lee things it needs some leementing..

I wanted the hot plate to be both heat source and heat sink, so I "soldered" a chunk of aluminum stock onto the plate and added PID. The cover is just a sheet of stainless steel acting as a reflector...

What caught my eye is the full length shearing. Thats not how I understand it's supposed to happen. If you consider how the boolit goes into rifling, it almost immediately starts to experience...

Interesting. flybyjohn, skid marks are usual with revolvers but rather rare with auto pistols. They explain it with the fact that bullet gains substantial linear velocity before engaging the rifling...

Yes, convective heat loss is what keeps molds from overheating during casting, and it may exceed 100W in open air.
It's rather tricky to estimate, so I'll try 100W and 260W plates and see. Will add...

Bismuth?

My hopes are higher. Lee pot is 700W and can heat up 20 pounds of lead to 700F in reasonable time. Heating up 1/4 pounds of aluminum mold to 400F would need much less than that.

(I'm reposting as my previous thread was deleted due to linking to ebay.. Hopefully google image search link is okay.)

Did you know that hair-straighteners have 2 PTC temperature controlled plate...

There are several types, steel, braided, copper, and copper-nickel. The latter one is best suited. We might use even plumbing copper tubing, but the brake line tubing has a kind of its own fittings...

I will. But this will have to wait for spring. It's cold winter season here.


Yeah, I expect it to look like boiling water. My plan is to make orifices small so that they work as restrictors. The...

Oh no, this is not for a lee pot. It's a smelting job outside and with propane burners.

Check out properties of superheated steam. Condensate can occur only when steam is cooled down to temp of saturation, which is around 130C at 2bar abs pressure. When you add heat to the steam, it has...

Your mistake is in units. Pressure is in units of force per area, N/m^2, and your final units is g/(cm*s^2) not g/(cm^2)

Simpler approach: you know that 9.8m of water head is 1 bar pressure. Lead...

11 g/cm^3 x 10cm x 980cm/sec^2 to bar

0.1078 bar

I believe so yes. But I take your input seriously. Why do you think it will blow up?

Guys, you are slightly overreacting. Please consider that proposed conditions are very different from typical industrial usage of steam.

Steam is hot. Right.
High pressure steam is dangerous....

I see. You probably work with steam that is used for heat transfer. It has to be wet or saturated steam for efficient heat transfer at destination through condensation. 275F seems to support that.
