Most people would advise an 8" grinder because of the hollow grind issue on gouges, but also because you really want the additional width on the larger wheels. Trying to accurately grind a tool that's larger than 1/2" in width/diameter on a narrower 6" wheel can be challenging, at best. Low speed is preferred but not required - HSS tools are not subject to drawing the temper like old carbon steel tools, but even then, fast grinders remove steel faster, and cheap wheels tend to be coarse and very aggressive, so there's no sense wasting steel. Once you have a jig setup of some kind for repeatability, you'll only be skimming the tool on the wheel. You won't be removing a lot of steel unless you want to reshape your grind profile. If you're looking for a low-cost option, I think Grizzly probably has the most affordable option at about $130 shipped. It's practically identical to the popular Rikon 80-805 (probably comes from the same factory overseas), which means it's basically an out of the box solution. You don't have to upgrade the wheels to CBN unless you want to; the stock friable wheels will last a long time. Answer from Silound on reddit.com

I've had a Ryobi chop saw for several years and like it just fine. Ditto a Ryobi circular saw. With bench grinders, look for a tool rest made of cast iron or beefy steel. The current crop of import grinders (sold under many names) have stamped steel rests which just don't get the job done. More on bbs.homeshopmachinist.net

r/turning on Reddit: Thoughts on Ryobi 6" Bench Grinder?
November 14, 2023 -

Very new to turning and grateful that this sub exists! I recently bought a lathe and have had it for just over a month. Not really turning "things" yet, just practicing cuts and techniques mostly. I purchased an 8 piece PSI HSS chisel set as I wanted to learn on traditional tools to start.

I have been reading as much as I can about the world of turning and have looked through the sub's wiki as well. When I purchased the tool set, I already owned an old Delta Universal Wet/Dry grinder (23-700 model) that I had hoped perhaps I could use to eventually sharpen the chisels/gouges but from what I'm reading and have tried, I don't think it will work (open to suggestions though if someone thinks I can use it).

I was at home depot today and decided to check out their bench grinder selection. Of course, in-store they only had one model, the ryobi 2.1 amp 6" bench grinder, though it was only 80 bucks which price-wise was nice. I was thinking about getting the grinder and following the plans for the jigs I found in the wiki from aroundthewoods.com.

Just wanted to see if there were more experienced folks here that may have a reason I should avoid the ryobi. I learned long ago to not just jump at something because it's cheap but given that I would build the mount and jig around this pretty exclusively to sharpen my lathe tools, it seemed like it could work.

Sorry for the long post but especially as a newcomer to this world, the amount of info available is overwhelming to say the least and some wisdom from people who know what they're doing would be much appreciated. I know a dull tool is a dangerous tool and I would like to get a sharpening setup going before I start doing pieces on nice wood blanks (so far I've just been using scrap pieces from around my garage that I'm sure are just shitty pine). Again thanks for any and all advice in advance, so glad I found this sub!

I think slow grinders are recommended, not the fast bench grinders you get at big box stores. I went all carbide as a beginner since I just want to get going without learning sharpening and stuff - I realized the sharpening was going to take more time and money than the lathe itself. Edit: I also read posts about people buying $150 CBN wheels ! Noped out of the sharpening thing pretty quickly

I've had a 6" Ryobi grinder for about 4 years now with out any problems. I'm sure there are better ones out there, but not for any less money. With a few addon mods like this http://homepage3.nifty.com/amigos/gr...ing_rest-e.htm I'm not sure the Ryobi was intended for a production type shop, but for the average home use it's OK.

Another belt grinder made from RYOBI bench grinder | The Hobby-Machinist
May 3, 2019 - I needed a small belt grinder. So, I decided to build the one using my cheap bench grinder as a donor. I removed a rough grinding wheel on the right side. That’s a great place for the belt. The motor isn’t really powerful – just about 250W. It runs at 3600RPMs.
