I referred to mine as a powder wedge.
Be glad to loan it to you if needed.

I'll ship it one way, you ship it back.
(I'll weigh it tonight & send pix)

48" dia sounds like what it was designed for.  My step-dad said to put it between the log to be split and a BIG stump.  Wrap a chain around it as it had a propensity to go airborne.  It has a powder chamber, standard cannon design.

first chamber is 1" diameter 3" long, powder chamber is about 1/3 of the 2" OD and is 3-1/2" long.

Good.  Investment in a tool is much better than an investment in postage!

Weld gusset to 'wedge', shackle a length of tractor chain to it...  other end to a tree so you can find it after.

Not bad advice.

I want to see smoke and flame!

The long-thin powder chamber will give max focused pressure along it's axis - just where you want it.

Do you fill both chambers with powder? Or just the 2/3" x 3-1/2" chamber? If you only fill the smaller chamber, what happens with the bigger one?


That's a really neat device and I'm halfway tempted to make one myself!

I would fill ONLY the small one.  Then a bit of newspaper to hold it in place.

That would leave the larger opening to be filled with wood when it was hammered into the log.

It also puts the powder into an area surrounded by an adequate thickness of steel to handle the pressure.

Ah I see. I didn't consider needing the larger chamber to allow the wood somewhere to go when you hammer it into the log.

I had not measured it before, but now that I know that it has a 1" bore I'll have to attach (temporarily) some trunnions.
