Thread: He's added a fourth axis
This guy shouldn't be allowed in a machine shop...eck! he's lethal.
I saw nothing wrong with that, everyday machining operation.John S -
Using a fly cutter to get a good suface finnish, " how dare he, some one call the HSE......."
Why are you posting random S**T, It had nothing to do with the original or previous posts...
I'll tell you what was REALLY nice about this project. The fact I designed the plates and cut them on my macine and all the bits, bearings, stepper etc. just fit first time, no filing, no drilling larger holes because one was .25 of a mil out because the dot punch slipped, everything just fit and lined up. I know it SHOULD do that anyway but I still find it all amazing and it was worth doing just for that glow you feel when it all goes to plan. My mate at work Kenny has been doing CNC lathe for many years, most at RR, and he says he still gets the same kick when the bits all just slot together first time every time. Wonder if others do :)Nothing is foolproof......to a sufficiently talented fool!

I find this idea of what he's done there highly dangerous and certainly wouldn't attempt that piece of contraption.
Flycutting has been done for many years, probably as long as there have been machine shops, safely and successfully. If there is any danger it's the fact the guard isn't in place so he could film the operation but that's all. You wouldn't think anything of mounting that part in a lathe and machining it, it's the same thing except the tool is moving not the piece (I'd say the fly cutter was safer IMO)Nothing is foolproof......to a sufficiently talented fool!
What are you thinking of making with your new machine and 4th axis?
Got the motor(2500rpm),got the pullys...one 50mm V type for motor shaft,one 4" for the spindle...will worry about gearing when its up and running? the speed contoller is a simple one for now ie it came off a defunctn router.
The bed will be 25x25x3mm box section,Ifigured its not worth making it big ie 600x250x250mm should do it.
Ordering the toolpost and tail stock from www.littlemachineshop.com
Why is it that you can get anything and everything under the sun from the states and you try here in the UK and its like looking for a needle in a haystack...really pi**es me off trying to buy stuff over here.
