Just to add that I spent an interesting 10 minutes or so viewing Gary's video today and the Acute system looks awesome, very well thought out.

At around the same time there was an article in MEW by Ralph Sparrow (MEW 117 July 2006) entitled "Sharpening with diamond discs


Nice to see that my design has helped others. One thing that wasn't known to me at the time was that diamonds are just about the best conductor of heat. I could see that the diamond wheel didn't cause blueing on the edge being sharpened but didn't appreciate the reason. This meant that I didn't need to cool the piece being sharpened and it didn't lose temper. To me this is the best reason for diamond wheel sharpening. As well as this there is no grinder dust thrown about, helping to keep the workshop and my nostrils clean. I also found that it worked on tipped tools as well as HSS.

Soon after the design was published I got a nice letter from a German model engineer who had made his version of the design but he had improved it by adding a screw rise and fall to make the vertical location of the grinding head more precise.

I have to add that my engineering started with D. Napier and Son at the beginning of the 1950's and I didn't touch a lathe or mill 'till I retired 19 years ago. I hated grinding as much when I restarted as I did at the beginning. My main modelling interest was and is flying model aircraft, freeflight and radio control but machining bits and pieces is invaluable.

You mean it's available now? the website still says "Coming Soon".

It is available, but perhaps the UK stock may not be in the country yet?

www.eccentricengineering.com.au/index.php?option=com_virtuemart&page=shop.browse&category_id=33&Itemid=3

Also see the UK Distributor page:

www.eccentricengineering.com.au/index.php?option=com_content&view=article&id=17&Itemid=43

There's also a USA disty.

.... but when I go there and click on < Drawings, Kits and Finished Units> the next page says "Coming Soon - Sorry for the Delay" - as it has for months.

(I'm in Canada so the UK site isn't attractive. Nor, in fact, is the US site as I suspect I'd be better off ordering direct from Oz)

I suggest sending Gary at Eccentric an email.

Bear in mind he makes them himself, in batches.

Apparently first batch despatched to UK beginning of last week, must have arrived quite quick because Hermes says mine has been collected by courier yesterday and is somewhere in their system I guess.

I ordered a diamond Toolholder directly from Eccentric Engineering in Australia to be delivered to me here in Canada, It was considerably cheaper than ordering from their US distributor. So I would guess that the same would apply to the Acute.

Coming in late with a few comments.

1) Thor's picture, is not too unlike the TipLap grinder recently acquired at auction by one of the volunteers at The WaterWorks Museum. By the looks of the gunge that I did not remove completely, from it, never been cleaned from new. Their ambition is to use it, mostly for End Mills, but obviously Lathe Tools and Drills should be fairly easy, once set up with a suitable cup wheel.

2) I use a Worden, (a barely started kit, bought second hand, ) which does most of what I want. One day I may become proficient at Four Facet Drill sharpening?

A fairly basic machine, but does what I want. For the amount of tool grinding that i do cannot justify a Vertex, EMG or anything that sophisticated.

3) A diamond wheel is ideal for sharpening Masonry Drills. Ground as if for metal, they EAT bricks, on the very rare times that I use them!

My take? Decide: What you want to do with a cutter grinder?, ie what tools to sharpen, How often? Size of budget? Space requirements? When you have answers to all these that you consider to be satisfactory, search for/ buy / make/ modify a machine.

And then use the sharp tools to make all the bits that you want/need, and enjoy yourself.

Howard
