More Binky! (well, sort-of)

Not a normal episode - and, as far as I'm concerned, a severe case of lathe abuse! I appreciate their skills in many things, but their machining speeds were all wrong...

a bit of behind the scenes is always good - amazing what can be achieved with a ML7!

If enough speed is good, more is better and too much is perfect!

I know nothing about lathing but have always wanted to have a go so found it really interesting.

I presume the squeals of protest where because the lathe was too fast from the comments above!!!

It's not often you can accuse them of rushing things

I haven't watched the video fully yet but I don't think that is a standard ML7 electric motor. It looks much bigger than mine and they are giving it a hot supper allright.

I have an ML7 and its so useful but with its relatively low top speed (600 ripems) and lack of power I have found that I can't get right surface speeds for Carbide insert tools especially. The chip load is just too high for the little thing. Taking tiny little cuts things take soooooooooooo long to do. I've been spoilt having used lathes in the past though.

I suspect there maybe other causes of squeals such as tip hieght , angle , type etc . I tend to get it wrong fairly often

I worked in a machine shop 25 years ago and used mills and lathes. No formal training, just what fellow employees passed on to me and a bit of trial and error. I'd love to have a lathe (and mill) myself now, but space just doesn't permit unfortunately. I'm sure there's a lot of learning to be done regarding work piece materials, tool types, travel speeds, setups and so on. I'm also sure I'd learn most of it through trial and error as well.

I did think it was working very hard for an ML7

I've occasionally messed up and let the fire out of the metal with carbide tools my Hemberg, but its a much more solid old machine that can get to 2200rpm...

I prefer the Raglan LittleJohn MK2 to the ML7. Continuously mechanically variable speed between 50 and a little over 2000 rpm and can be varied without stopping to change pullies.

And now - part 2!
