In engineering, we would invariably use parrafin to drill or machine cast iron, and Brass. No idea why parrafin, but it always seemed fine.

Thanks Steve. I think Rolls Royce Derby came up with the concept, but don't quote me on that. They beed high pressure air from the compressor section, down the hollow turbine shaft, back towards the turbine blades. The blades themselves are perforated with tiny holes. This compressor air (...

As Richard C stated, heat rising from the middle, cooler air drawn in down the sides This aides in cooling the sides, (That's how gas turbine blades are cooled, called boundary layer cooling.) and if not too tightly packed, can make the burning as efficient as a draught from underneath. ( plus...

Probably not what you want, but mine live in a hinged wooden case, which will shortly be screwed to the wall, above and behind the lathe. Its a work in progress...

I'll post some pics as soon as allowed ( don't know how many posts I need to do before I can post pics though). Before joining this forum, I had'nt thought anyone would ever be interested in my knacklings. Hence I didn't take any "before" pics, only "afters".

Thanks all. Deeper in thought now. Think I have some carbide end mills. ( little boxes stashed everywhere !)I will have a rummage

That could be a better option, assuming the back end isn"t hardened. Looks to be around 55 mm long, which will go nose-first into my metal lathe chuck. Thanks guys.

Yeah -I'd thought that too. could have done that here, except my little lathe bed isnt long enough to mount it and get a drill/ream in the tailstock ! (In fact I'll be lucky to mount the tailstock at all). That idea was always going to be my last resort option. I could make my own from scratch...

Thanks Mike. Will do. ( there aren't too many.) It's a virtually "zero budget-go with what you've got" kind of thing. And it's on-going anyway. The metal lathe has taken nearly a year. Just nicely started on "me hand tooils" this spring. Some were rust-bags, some hand me downs. Some were "...

Hi all. Anyone know where I might find a 4 spur drive centre, to fit over/ onto a 1/2" motor shaft ( grubscrewed to the flat on the shaft). Looking for around inch and a half -ish spur, but must be 1/2" (12.7mm) parallel spindle mount. Thought I'd seen them before, now I want one, I can't find...

Hi all. Thankyou for letting me join. I'm Gary. (Gazbo) in sunny West Yorkshire. Heavy engineering for 40+ years. Made repugnant in 2018. Now in a supermarket job, but I have always dabbled in general DIY, and small woodwork projects for personal use. A bit more time nowadays -to do things in...
