    I don’t use mine for sharpening bits, I do sharpen chisels and center punches when needed and deburring a drill bit when it happens to slip in a chuck. Otherwise I use it for shaping metal. I just never did get the knack for sharpening a drill bit. It’s quite an art to be successful and takes a fine grinding wheel that is well dressed too.

    Do you guys ever dress your wheels? I have a couple grinding wheel dressers, One’s really course to get the face flat again and the other is a fine diamond tipped to finish it off.

    I have a dresser for mine, when I bought my old grinder it had a really bad groove in the wheel so I picked up the dresser, flattened it out in no time, but lots of dust. I was surprised at how well it worked.

    I do sharpen chisels

    Do you use a special wheel for this? The only time I ever tried I ended up burning it up really quickly, I thought I was being careful and wet it down before / after. I’ve been hand sharpening since then.

    There are specially formulated wheels that have grinding material that is better for sharpening – Norton makes them. They come in white, pink and blue colors. The best advice I received while learning about turning and sharpening was a slow speed ~ 1725 rpm is needed to avoid burning the metal. The grey grinding wheels and high speed grinders are not kind to chisels.

    Jet and Rikon make slow speed grinders for sharpening. Here is what the Jet includes for wheels: Includes two high-quality Norton® wheels: 80 grit 3X Blue Ceramic Alumina K Grade for coarse grinding, 100 grit White Aluminum Oxide for finish grinding.

    Thanks Lon, I actually have a Blue wheel I use for sharpening bigger things like pry bars and axes but didn’t have luck with the chisel on it, although that was a few years ago. I put together an article on hand sharpening that is going up sometime next week, but I’m interested in the power options. Sounds like it might need a bit more of a specific setup rather than my off the shelf grinder. I would think you would need a jig of some sort to get the angles perfect?

    Check out that Jet Slow Speed Grinder, it has received great reviews but is pricey. It is the slow speed that makes the difference with the wheel. Also checkout the Oneway Wolverine Grinding jigs. Others would argue the Tormek is a great choice. I use the Jet with Oneway jigs for my lathe tools. You typically do not put the finish on them like you would a chisel though.

    Nice I’ll have to check them out, my shop is so crammed for space I don’t think I’d have the room since I don’t do a ton of sharpening, but it would be nice to have a way to do it a little quicker. I’ve seen the Tormek setups in some of the Alan Holtham videos but never the Jet, I’ll have to give it a once over, the Jet stuff is all pricey but good quality stuff.

    I should specify the chisel’s I sharpen are for metal, My grinder would be slow enough at 1800rpm but of course it depends on how big of wheel you’re using. Mine has 10″ on it

    This is so weird to me, The power of BTP and Google. Since I’ve decided to refurbish mine I was searching for Bench grinders on Google to see if I could find anymore details about it, I’m trying to find out how the original tool rests were and the color and year so I can rebuild it as close to original as I can. So as I’m going through all the images on Google I surprisingly spotted one just like mine, So I clicked on it and it IS mine LOL. I clicked the page option and it took me straight to here. I guess from the pics I posted months ago, It’s the ones I circled in blue…. Scary!!

    The power of BTP and Google.

    I am amazed more and more how much BTP dominates google images search. Amazing.

    I would still like to think that the worksharp station could handle a wide variety of sharpening needs without totally breaking the bank, though I know the tormek is highly regarded (and $$$$).

    The scary sharp method seems like a great way to sharpen chisels and blades from planes…. http://www.workshopheaven.com/tools/Scary_Sharpening.html (UK though 🙁 man)

    The only place I can find a similar one to the one there is here:
    Glass setup here: http://www.rockler.com/plate-glass-sharpening-system-fine and the abrasives here http://www.toolsforworkingwood.com/store/dept/THS/item/ST-MAF.XX and honing guide here http://www.leevalley.com/en/wood/page.aspx?p=51868&cat=1,43072,43078&ap=1

    (more info on scary sharp here http://primeshop.com/access/woodwork/scarysharp/)

    Though lee valley offers a similar looking machine to the worksharp station
    http://www.leevalley.com/en/wood/page.aspx?p=48435&cat=1,43072,48435

    Lastly – you mentioned grinding jigs, and lee valley has a nice setup for doing finer grinding it looks like: http://www.leevalley.com/en/wood/page.aspx?p=32972&cat=1,43072,45938

    I’ve got a craftsman I picked up at a garage sale last year for $5. Use it mostly to derust things I’m working on and the occasional metal shaping project. I do need to get some new wire wheels though, the one’s I’ve got are coming apart and shooting wires everywhere, including sticking into my skin.

    Its actually a highly sought after model.

    6″ wheels.

    Not sure on how old nut I just saw a picture online of an identical one and it listed 1970. These are refered to as Craftsman Block grinders and were manufactured from the 60’s to the 80’s. Was manufactured by Delco or Paramount/Allegretti & Co(who continued Delco’s designs).

    That’s a nice grinder. When I find an old one like that, for a good price, then I will have one. Until then, I’ll just wait.

    It is not possible to write on this topic. Hello to everyone. I would like to make a serious contribution to this issue.

    My eyes shine when I see my old ones. I came across this bench grinder review recently. but I think this product is much better than stated.
