Anyone know the story behind this?

See, even if I knew what it was and had a use for it I wouldn't use it.

It's far far too shiny. Better to keep it under a cover and intimidate people with it.

Yah, I got bored one weekend, raided my scrap pile, and made that. It's ok for a hack job. I still need to draw up some plans.

Why do you ask?

IF you read the link, it has all the details.. ou will need to use google translate or something similar..

He has some other neat stuff on that site too.

Granted it's nice but it would have been better to use materials more suited to the job.

It does look like a nice piece of work.

I am tossing around ways to build a good bench-top drill/end mill sharpener myself (since I can't afford any compact decent one already-made...). Haven't seen a lot I like yet,,,, though I admit I've never used one at all before.

Seems like they all have about twenty places for grit to get into the slides and ruin them. Quorns, Brooks-Stents, ect. I can see that they are very adjustable, but they rely on a bunch of precise fitting parts and the grit management is basically non-existent. The only way they would make sense maybe is if you draped a clear vinyl shower curtain over the thing, and made two small holes for the grinder shaft and drill bit tip to stick through. :confused:

Looks like Joachim Steinke's work

At Polaks (http://www.polak.cz/en/page.php?4)we had similar looking end mill sharpeners - just bigger. I wish I had access there today.

Heck I wish I was still the manufacturing engineer there:) - my area was to design electrodes for EDM, beautiful engineering.

Sorry for the silliness, but I think this sums up my reaction nicely:

Oh, and any thoughts on what the big bar mounted with the grinding wheel is for? (the one on the far right of the pic)

I presume it's the drive motor in a can with backplate and belt cover. I could be wrong.

adatesman the big bar you asked about is the motor drive for the spindle if you look at some of the previous drawings you can see it.

Eat your heart out John -- it's bearing bronze. Seriously :)

Although he calls it a "Mini Bonnell Mark II", it's much more like a Stent.

Work of art!

http://www.metallmodellbau.de/MINI_BONELLE_II.php

Lots of details on his web site, nicely documented. Yes, it is in German but worth taking a look at.

He has some great ideas in, from the "engraving" (decal printed and sized on a computer, than transferred to a clear sheet) to the belt drive.

Ganz Toll! (Pretty neat!)

Did you notice that he made a vernier with that laser printed sheet? Very cool :)

Hey Doug,

I'm in exactly the same place as far as building a decent bench-top grinder. Would love to compare notes with you if you decide to proceed.

Thanks,

Looks like it could be somebody's Master piece. In Germany, when after 5 years as a journeyman you decided to go for a Masters degree as a Mechanic or any other metal trade, you had to submit a "Master piece". I do not know if that is still the case today (someone help me on this). To bad they relied on a computer translation and did not spent the money for a professional translator.
A warning to all who think Google and other computer translating services can be used for technical translations.

Yes its very pretty, would look well on the sideboard, but does he [U]use [U] it regularly? If he does, what does it look like after 6months, and are there any pictures of the stuff hes sharpened with it?

I'd take it with me on job interviews.

Beautiful job but wrong choice of material. Just eye candy in my book.

So what is the better (or best) choice?

Ether steel are cast iron. You do not want aluminum on a grinder . Will ware out to fast with the grit. That stuff will get in every thing.
