View Full Version : What should I do with this old girl? (HaRo H2Y grinder)

I went to an auction to buy a lathe in August and they had this old girl there, the auctioneer said she would be going to the scrap yard if nobody bought her. I couldnít let that happen so I took her home.

Itís a HaRo H2Y w/ a 600v motor.

I am in the process of building a 240v RPC w/ a 600v transformer and for the new lathe, so I eventually get the grinder running with that.

I really donít think I need a grinder, although I could use a surface grinder.

What would you guys do?

Sharpen your tools and cutters with it. You could do with a few attachments to make the job easier but you can do a lot with a small swivel and tilt vise.
It's also capable of surface grinding, depends on how big the items are that you want to grind.
If you were a bit closer, I would be happy to take it off your hands.

Dave if you were closer I would give it to you for what I paid for it, and it wasn’t much!

Ha ha. Thanks.
I'm sure there will be someone on this forum who's been looking for one of these. It appears to be in decent condition.

Boy would I love to have that I've just been hired to sharpen chipper knives , 4 double edged knives per set , any where from 2 to 10 set per week.

There's a kind of manual for it here: http://s259.photobucket.com/user/olesteen/library/HARO%20H2Y%20grinder%20manual?sort=6&page=1

There's a short thread at PM: http://www.practicalmachinist.com/vb/abrasive-machining/haro-h2y-grinder-192584/

It looks versatile.

Looks VERY nice. Much nicer than my Greenlee base with a TP grinder as a head. (I had a chance at a disassembled "real" grinder a few years ago, but no place, and no time for the project then.)

What you need is what McGyver showed here some years past.... long thread where he built a multi-angle holder.

Find room. You will find uses. Hardly anything built in Geneva is going to be low quality.

A bit closer and I would come get it!

Set it up to sharpen the neighborhood lawn mower blades!

Looks a nice tool and cutter grinder to me, also dead useful as a giant bench centres for measuring stuff

If you do sell it don't forget to send the poppy to your old pal BIG AL LOL. Seriously that's a nice piece of machinery.I could think it would be snapped up on ebay.Why not try it ! you might get a good surprise.Alistair

dm, When and if I get it up and running you are welcome to swing buy and use anytime you want. ;)

dp, thanks for the links, it did come with it's own manual... although a little tattered.

JT, That is something to concider, but I really don't know how much I would use it. Almost everything I have is carbide, although I guess I could get the right stones.

Or even mine ;)

boslab, That's what I thought, the table is great for something like that.... I was even trying to think of a way to adapt it to flute barrels.

BIG AL, I guess I could try, but most people in the States shy away from Canadian sellers, or maybe it doesnít come up in the searches. About 10 years ago I watched and bought a nice 6" or 8" (don't remember) rotary table. Nobody bid on it and I got it for $80 ... I drove over and picked it up from a guy in the city.

Note that it is set up as a round tool sharpener - end milling cutters, reamers etc. as well as horizontal milling machine cutters - albeit shown as ready for a mandrel too - all between centres.

So I have been looking at it and thinking... and thinking... Would a new wheel be all it takes to turn this into a surface grinder?

Hi Darren, well whatever you do it will never be as good as a dedicated surface grinder, they are a different machine and built to do the job intended, however if you fit a suitable wheel it will work as a surface grinder but will not be as accurate. A good surface grinder plus good operator will work to a few tenths limit, a cutter grinder will not do this for you but how accurate do you want or need to be? It will work to a lot less than 0.001" limit if used with care.
I have an ageing Boxford that is really a tool and cutter grinder but was sold as a combination machine doubling as a surface grinder and it works well enough for my requirements, I can keep to less than 0.0005" tolerance on thickness i.e. Surface grinding
For the small cost of a suitable wheel I would try it, a magnetic chuck would also be a wise investment should you decide to keep the machine.
Just my thoughts good luck John

All it takes is a diamond cup wheel to get going doing carbide.

For reamers, end mills, etc you need a tooth rest, no problem to make.

yes, it will do surface grinding, but not as well as a purpose-made surface grinder. Depends on how the table ways and travel are.

Hi John, Thanks for the info, I think I will try it. Right now the only 2 things I want to do are an old mill drill table and a tilting table that has seen too many miles. I was thinking I would use the clamp set for now. The only time I used a surface grinder was in trade school in the '80s and it had auto feed. I guess that I will have to manually feed this one. When I stuck my head under the table the feed system looked like ball bearing and cable feed. ĖDarren-

J-Tiers, I only have carbide tooling so maybe you are right I should start sharpening. There were a few extra rests with it, I will take a closer look. Thanks...

Gee, it may be easier than I thought to surface grind with the HARO, I found this thread on a google search

http://www.practicalmachinist.com/vb/general/haro-10-tool-cutter-grinder-243817/

And that led to this brochure;

http://www.harotechnologies.com/pdf/haro_baseline_usages_examples_en_20140909.pdf

I have to increase the service to the machine shop to 100A and then finish the RPC for the new lathe (Kinwa - Chin Hung) anyway, so when I get the 600v into my machine shop I will move the grinder in and get her going.

Thanks for all the help guys!

Sheesh... and I thought "chinglish" was bad. Whatever they meant by "Strawberries", I do not know.... maybe some form of "burr".

That Haro brochure is worth a look-over, if only for the fractured "Binglish". And the collection of pictured non-obtainable-for-a-reasonable-price accessories.

If you need you can use my 8x24 Brown & Sharpe surface grinder. Im in west Edmonton.
