REALLY stupid question (turning big stuff)

Let's for one second set aside the safety aspect.

Something I've been thinking about - to turn a bowl, what do you need? A surface to mount a block of wood to, and a way to spin it, and preferably a way to vary the speed at which it turns.

Anyone ever seen someone have a machine shop mount a chuck or flange to a car hub (perfectly balanced, of course) and mount it to a properly jacked and blocked car? Remember "Commando" when the village was using an old Jeep pickup to turn their belt-driven water pump? At least I think it was "Commando".

You would then have almost infinitely variable speeds, especially the extremely slow speeds for large, not-yet-balanced blanks. No worries about not having enough room for the throw. Very heavy-duty, at least as far as lathes go.

This is not something anyone would ever try, but do you think it would even be possible?

That's exactly what I was thinking of, as I looked at my 1975 International 3/4-ton 4x4 pickup with the granny low gears - which would be doubly nice to mount a chuck to a spare axleshaft and never have to even remove the tire to change into "lathe mode", since it's a full-floating rear. :)

My friend and I almost did that. We talked about setting my truck on the side of the hill and jacking up one side. Then removing the rear wheel and bolting a piece of wood to it.
It's been done of course. I believe it was in Australia or New Zealand. The used a tractor. If I can find the youtube video I'll post it.

I might even just be able to have the end of my axleshaft drilled for a Morse taper...slap a chuck in and step on the gas!

Hey if I thought women would come to my hot tube I'd start the glue up tomorrow. My new (to me) truck has a V6 instead of the wimpy 4 in my other one. that' means bigger bowls. :)

So I scrolled down to picture 2 and wondered why they bothered, that blank doesn't look particularly large at all.

Then I got to picture 3 and realize I'd been looking at the faceplate

I just had to go to the web site to check it out….some of the pictures puts it into even more perspective…

The outside...maybe
But I'm letting someone else do the hollowing..
Looks like they made the same decision part way in.

Ed moulthrop did a lot of very large turning. He and few other played with this a decade or two ago. They had tools that were specially made too and were long like spears.
It is a lot of work! I have turned up to 20 inches or so and it is work and they take a lot of space.
Moulthrop died in 2003 and his large pieces are available on the net. He has a Wikipedia notation.

It was Predator. Love that movie!

Got a nick on my finger in the shoppe once, my wife said I should come put a bandaid on it because it was bleeding. I told her, "I ain't got time to bleed!"

I'd be impressed if it were from a solid chuck of wood.
