I just saw this pop up down the right hand side of the page and thought it worth having a look at, for the sake of all those who block the adverts this is what they could be missing out on.

Looks quite versatile and quite well thought out.

Had a good look at this at Doncaster.

Like all Eccentric items it's very carefully thought out.

Very interesting bit of kit !

While i was watching the video i was thinking to myself how could i make one of these but by the time the vidoe had ended i was thinking that with the amount of thought and design work he has put into it buying one is well worth the investment ! They are not expensive - considering thier versatility .

The extended ER32 collet holder also looks good but for my lathe which has a bolt on chuck i would either make up a mandrel with a MT5 taper to screw the ER chuck to and lock the whole thing in with a drawbar through the lathe spindle or bite the bullet and make a bolt on ER attachment.

Thanks for the link Jason I do sometimes look through the 'adds' but must admit it's been awhile.

I still think the name could have been better thought out ! Just add a "d" at the appropriate point and the meaning changes dramatically !

XD, don't know if you already have a flange mount ER chuck but they do an extender that fits the nut thread so you can screw that to your existing ER.

I suppose those with bedair type ball turners could just slide them about on a flat plate and make up the extra bits to do the larger radius and copy turning.

I would like to have seen how it coped with steel in the video rather than just soft brass and ali, from using hand gravers these materials are a lot easier to cut freehand than steel.

At the end of the video there is a section showing the device being used with a wide range of different materials including steel, titanium and stainless steel.

Thanks Mike I missed that bit, that's what happens when you are watching both You-tube and the Le Tour on the TV at the same timeblush

I was sufficiently impressed at the Doncaster show to buy one. I've enjoyed using it since then with excellent results. Yes, it is a little expensive but is well made, and you are paying for some good ideas and the tool's development. It has opened up a whole new aspect of lathework and is worth it for that reason alone. Working a tool directly by hand rather than twiddling knobs is a refreshing change and is perhaps more akin to wood turning.

I soon found the importance of locking all slides. You are pushing the tool forwards against a pin and any backlash in the feedscrews can spoil the work. I made up some special extended Allen keys to suit the locking screws on my Super 7. I also turned up a vertical pin to fit in the holes in the bedplate. That enables the tool to be aligned with the centreline of the lathe when ball turning and allows the tool to be set to the radius of the ball. That should be part of the standard kit but is easily made.

It would have been better if there had been a live demonstration at the show rather than relying on a video but hopefully that might be possible at future shows.

Same thing but on a rather large HBM: https://www.youtube.com/watch?v=eTmF2gtB7AA

Lovely work on a large HBM. Does this guy have a very understanding boss, or does he own the factory... costs to run that machinery that is not producing goods is not very profitable nor economical.

Not sure... Some of his other videos show "proper work" so it does earn its corn sometimes!

Every time i see one of Garry's new tools i am inspired by the attention to the detail and the many accessories, on this one right down to the finger grips on the tool body. Also the way the center point can be offset to completely turn a ball caught my eye. first class job.

Neil,

My point was that his tools for use on the lathe - at the bottom of the PDF pointed to - were the same design as the Eccentric tool-holder. I remember seeing the Fonly and its tools being demonstrated at the London model railway exhibition in the 1980s and I always meant to make some of the toolholders to use on my lathes, but never got round to it. smiley

Jim,

Thanks for the 'fonly reference yes

I was especially interested in the original 'graver support'

... that's a Lorch item that I have not previously seen.

My Turnado arrived today and what a great piece of kit it is

The toolholder is indeed a thing of beauty

My lathe is a colchester 6.5 inch CH so to fit it i made a flange like the toolpost has so its really quick to fit just 2 bolts to tighten and its on.

Then the pillars wanted shortening to only 6.5mm so a rethink was called for ...i replaced the pillars with 25mm squares of GFS 6.5mm thick tapped a central 5mm hole and used the original bolts ...bolt 4 of these on and the bolts protrude just enough to locate the top on

The central one i made a 6.5mm plate bolted on the bottom plate and the original screw screws into the plate

First quick tests worked well on some 30mm dia black nylon
