With every step of the thing, you incur more losses. Trying to run a spinny thing, to a generaty thing, to a con/in-iverter thing, to a transformer thing... And a "standard" of conversion efficiency is 80% So... 80% of 80% of 80% of 80%....

A 6/1 running at nominal is 6HP = 4474W or 4.7kW. (*0.80)   You can tap the motor out another few hundred RPM for more power. (minus the losses)
I think an extra 50 RPM gave the 3/1 another 50HP but sorry I can't remember the maths behind that.
I don't know what the stamford head will do, or how it's coupled.

Personally, with that engine I'd be looking to the hell rectifier setup (skipping inversion/reversion/conversion) and running DC welds straight off. I'd be surprised if you could stall it on 2.5mm rods.

Yep, watching old foundry workers doing their trade plus making a steam engine for LMS was a bonus. My mates Dad was a pattern maker at Garden Island Dock Yard, Sydney. When we visited the yard the old pattern room still has drawings on the timber floor of what was being made, checked or designed.

It's interesting, what gets lost to time, cos people "nowadays" think it's too boring to bother recording... how much ancient knowledge we've lost as a species.

Then, there's the kids recording damned everything to put on the net cos they think anyone gives a hoot.

Oh and I was thinkin people could just post a video link in this thread...

Sorry if this board already has one of these threads, searching didn't find it.

Anyhow, here's a vid that piques all my interests

Wow, that's a nice bit of iron! Looks like a fair whack of travel in all directions. That'd come in handy!

Beauty. That's the ticket.

I'd say a bigger font, me minces ain't all they used to be, but I've also learned how to sort that out with two fingers on the touch screen of me Chromebook!

While looking at the page, hold down the `Ctrl` button on your keyboard and press `+`
That should zoom you in, on most browsers.
(You may need to hold `Shift` as well, depending on your system)
OR
Hold `Ctrl` and use the scroll-wheel on your mouse, if available)

I'd have to dig through old pics, sounds like you're sorted now anyhow.

But the fuel rack and the angled slidey bizzo have to go in the right way.
