Thats true. What if you stuck a rod into the lead while it was still boiling, and then used pliers or channel locks to pull it out of the mold?

im not gonna play with lead if it is boiling , i have a lead pot to do it in

[warhead052]

Right after you pour it, just shove in some sort of metal rod that won't melt instantly and then pull it out the completed round with it.

Here is a .515 inch diameter that would be close enough since you can not tell us what diameter you want.

If $20 is too much then maybe a new hobby is needed.

jsefcik, cut the block in half then clamp it back together, then drill the hole. That way your hole is round and your mould will split to get the ammo out.

That dewey-1 is one smart cookie.

Sounds fun and all, however wouldnt it be easier and cheaper to buy a bag of marbles?? I mean unless were hunting dinosaurs!!

Not smart, just an old fart with a lot of common sense!

Rather than cutting in half, just join two blocks together (bolted/clamped), then drill/mill the desired hole size. There is polishing/sanding the cavity so it is relatively smooth for easier removal.

The mold I linked to will be a hell of lot better with wadding than a home made one.

I would make a drawing but someone can not measure the ID of the barrel for me.

I was able to make my old mold, got a wooded dowl and drilled a hole in it then wrapped a double a batterie in the foil , took out the foil tube and put it into the hole in the dowel and poured the lead into the foil, i wanted to use foil because its cheap and the lead wont stick to the wood,

once the lead hardens and remove the foil and put in a tumbler and nice and smooth, works good!!!!!!!!!!!

[Crna Legija]

Just use a drill, and get a block of wood, drill the hole your self, then use a saw and cut it in half.

If you did that your mould would be the thickness of the blade smaller because of that the bullet will b oval shaped. Cut first then drill the hole.

[Technician1002]

Even easier is to use two blocks clamped together. No need to cut it apart. Just drill on the junction of the two blocks.

touche (how do i get the funky e?)

[Labtecpower]

you mean like touché?

In the past they used water-soaked wooden bullet molds. I guess it worked well, as they have used it for a long time.

[jazzman56]

Is there any chance of getting a piston valve (barrel sealer) machined/lathed for a 1 inch brass tee. (sorry not quite sure of the inside diameter). I would like it to seat at a low pressure (so i can use a bike pump).

Something like daniel0663's piston




EDIT: JSR how would i go about measuring this inside diameter, i am assuming that i can't use a ruler .

Thanks Jazzman

[jackssmirkingrevenge]

(sorry not quite sure of the inside diameter)

That's quite an important detail if you want a quality part...

[Labtecpower]

You can get quite good results by using a caliper.
