Yes Steve, it was fast but not very accurate, but good enough! I am good at that sort of thing.
I am thinking ahead. Screw cutting, I had originally thought that it would be good to build an electronically controlled leadscrew. Then I realised how many complications are brought into that.
My latest idea is to use timing belts and pulleys. I don't want to make an unlimited range of threads. Maybe just a few to start with, .5,.75, 1mm. If there is a need for a special thread later on I can purchase the needed pulleys. I like the idea that it would be very quiet running rather than gears that rattle. Is this a practical approach? Has anybody tried it? Surely it would be accurate enough, it is used for timing camshafts on car engines.

Just as well he came early - I wanted to mow the big field today and when on the tractor there is no way I'd hear mobile phones , gate alarms or delivery people yelling !
Andrew, when I am mowing the rugby pitches with our Deutz 95 I wear a decent set of headphones plugged into my phone. The cable these days nearly all come with a microphone and switch to answer calls. You can also tell when you get a message as the radio cuts out for a while. I bought a set from SkullCandy!!

Highly recommended.

"You see but you not observe" .... Sherlock Holmes to Dr Watson.

The rope makes but one complete turn. The movie clip of it doing so is repeated ad infinitum, but it's the same single turn.

Spent this evening trying to make a Ironman style oil burner for the Tiny Furnace. I have a lot of used cooking oil I'd like to burn instead of buying propane. I also want to melt brass (quite a bit higher temps than Zamak or aluminum for that matter) for the next few melts of handles and such for the lathe, so I thought I'd take the time to work up a new burner. Not much success using a makeshift version I came up with after work in the few minutes I had before dark to try it out, but I think I can make improvements to get it going properly......we'll see tomorrow.

While I have a very successful Kwiky style atomizing burner on my larger oil burning iron furnace, I'd like to do away with the compressor, as that one needs, and use a blower-only as Ironman does. But I do need to scale his down for the tiny furnace and brass, both in heat output and size.

Also today, stopped down at Lester's old time machine shop and bought some 1-1/4" hot rolled, and 1-1/8" cold rolled -- the latter for the tailstock ram.

Whilst my main lathe is out of action I have been working in wood. This little lathe is very small and this would mean that I would have to bend over to use it. I decided to make a chest of drawers to raise it up to a comfortable working height and to provide storage.
I was lucky to be given some 20mm plywood so I made the carcase and two drawers. The other four drawers were a problem as the plywood had run out and I didn't want to buy more when scrounging would do. I managed to acquire a panel from some sort of industrial boiler that was made from 2mm aluminium. I used this to make the sides and bottom of the drawers, I had already made the fronts and backs of the drawers from the plywood.
I have ended up with a very heavy and very sturdy stand for the lathe at no cost.  It is not beautiful but it does the job!
