Update on what did you do today. My little screw type splitter is done, could use more power though. Looking to improve with a 2 hp motor, one hp is a tad low.

Looks very nice! Any video of it in action?

I saw some videos on You tube, they work slick. I wanted a compact one for at the lake.

So how do you cut a spiral thread on a cone??

Saw a Russian site. Hand feed the cross slide with a rapid carriage travel from left to right, leave the traverse lever engaged, reverse and repeat. Not too hard once you start. Not a 60 deg. thread form. Could have used the thread feed screw for the same result and pitch.

Hook it up to that thing in the background.

The one you made looks nice and sturdy. Nice job on the belt guard, too. I'd probably be getting in a hurry by the time I got around to a detail like that.

Beautifully done but isnt an axe quicker and cheaper:)

An axe might be quicker and cheaper, but building machines it's a lot more fun:) Nice work metalbender!

It is nice ,I would like to see the thread being put on the cone though,still trying to wrap my head around how its done.

Very nice work.
Can't figure out how you cut the threads though.

I have one like that I attach to the PTO on my tractor.
It's the fastest, easiest splitter I have ever seen.

PS:
You used to be able to buy the threaded cone from the company that built my splitter.

Still can ------

Thanks for the replies. Having had surgery on both rotator cuffs makes splitting with an ax a real pain. The belt guard was made using my home built slip roll. I used to build stuff out of necessity when the family was young, serious lack of funds. Still have a chop saw and hydraulic arbor press I built many years ago. I could go out and buy stuff now but that defeats the purpose of all these tools in the garage. It's just plain fun to build things, engineering on the fly.

You don't use an axe to split wood, you use a splitting maul or wedges and a sledge hammer.

Nice job! That's the first one I have seen with that fine a pitch on the screw.Is the thread that fine because it's being driven faster or out of lathe limitations?

I made the threads rather fine to try to compensate for only having a 1 hp motor. Even with that, it's under powered. Next week at the lake will tell, most wood is around 4-6 inch stuff. Having more power one could cut 4-8 tpi. I just used the regular feed, not the screw cutting feed, seat of the pants engineering. The tool is ground for a buttress type thread. Might make a new cone, longer taper, smaller dia, coarser thread, or, sssssspppppend money for more power. New cone first I think.

Have you considered putting notches in the thread to make it remove material instead of just pushing it out of the way? It would work like a regular tap instead of a fluteless tap. Seems like that would reduce the load on the motor.

If the serrated cone removes material, I might wind up with a tapered hole on the wood. Watched lots of u tube vids, mostly from Europe/ Russia. With 220v being the norm, most of the splitters there are using 3hp or more. I have access to the 30a RV plug at my trailer so a 2hp drawing 19a at 110v should work. Next week will be the trial run, lots of time to get it to work.

You could probably get a three phase motor and VFD for less than the cost of a single phase 3hp motor these days.

If your wood is oly 6" you could have made a bigger stove instead :o

The wood is only for the campfire, my caravan doesn't have a wood stove. Just pokin' fun there. Have a 31.5 ft trailer at a private campground 300km north of where I live.

Just a little update. Made up a new cone, .300 in smaller dia, 1.00 in longer with 8tpi. Used the threading half nuts this time. Still no go in really tough wood. I'll have to try it on the wood pile at the lake Mon or Tues, if it doesn't do the job it's getting a 2 hp from Automation.
