Practice on scrap with your chain saw circlets before attacking your good material. Those disks are very aggressive, and tend to pull themselves deeper into the wood.

Another good attachment for the grinder is a flap sanding disk, one with a convex shape. Can clean up a lot of the roughness from the chain saw disks.

I can’t say whether there is any advantage to the variable speed. I have never felt the need for it. Also, the guard on a 5” grinder will somewhat restrict your use from a 4 1/2” disk

I work with angle grinders constantly. Metabo grinders make some unique grinders that make them a must have for the pipe trades. I honestly wouldn’t buy anything else. However for home hobby use I have a metabo, DeWalt and Makita. I find they all work well. I prefer paddle switched grinders (have to hold the paddle down to run the grinder) over a on off for any type of grinding / heavy stock removal purely from a safety standpoint. For wire wheel or polishing pads / sanding discs use I like the on off switch style over a paddle switch. You milage may very depending on work flow.

Thank you for the suggestion, I will look into those, I’ll take it slow before I move onto the Walnut that I hope to use, that stuff is pricey.

I think I will look for a paddle switch, being new to them, I would rather err on the side of caution.

King Arthur heads work, but my experience says they cause stitches also.

I use both the Kutzall disks and 24 grit sanding disks. Both work very well.

I also agree, practice on scraps first.

That’s pretty scary, definitely will be going with a paddle switch model grinder.

What specific attachments were you using? User error?

Last year I bought a 5” Hitachi variable speed grinder and I love it. It’s very powerful, smooth, and relatively quiet. Disclosure, I don’t have a lot of experience with angle grinders. But I’m wanting to pick up a Kutzall disc and build one of the coffee stands from the 360 Woodworking website.

Nice sentiment, but I have 3 little kids plus I work long hours, I don’t get too much time in the shop, so for me speed is the name of the game if I ever want to finish a project.

Currently my “shop” is filled with 2 bookshelves in pieces that have been waiting for 2 weeks for the final layer of Varnish, hope I’ll get to it soon so I can start another project.

Bit the bullet, went for a Metabo 4 1/2 inch grinder with a paddle switch, found a good price on the anniversary model, like the colors and seems to be a decent tool. Since nobody is encouraging variable speed why spend the extra $100 for it.

Slider, you might want to consider some serious dust collection and/or wearing a respirator and maybe even a face mask.

I don’t think I would use this inside my garage, way too messy, driveway seems smarter.

I always wear a respirator and glasses while woodworking, I have asthsma and saw dust seriously irritates it.

I agree, a face mask would be nice, but I have a big head (not just figuratively), and I need my respirator to fit under the face shield. I usually wear goggles when I use my lathe as ship go everywhere, but this seems even more extreme.

My angle grinder story:

I use an angle grinder a lot. Can’t beat them as a tool that when you need it nothing else will do. Anyway, I also weld and all my cuts are done with a 4” grinder. Why 4”? Well, my brother worked in a place where they had 4” wheels laying around all over the place. He’d bring a few home each week… for 30 years. I’ve got a huge box of them.
Anyway. I started out with a porter cable. It lasted a good while… about two years. I used it a lot on metal so I thought that was a good deal. Next when that burnt out, I decided on some harbor freight cheap ones. I bought three. Each lasted, I kid you not… about 20 minutes. I then purchased a milwaulkee. I got over a year out of that one. Not long enough.

Finally I went to sears only because for 7 bucks I could get a clean replacement warranty for 3 years. I thought, “It will burn out and I’ll never have to buy one again”. That was 8 years ago. It’s beat up, welding burned but still going strong.

Now, I’m not promoting craftsman tools. Except for wrenches I own very few of them. But this one is a gem.

My first one was (and is—it’s still my favorite) a B & D that I bought at least 35 or so years ago, an Industrial model, back in the days when “heavy duty” and “Industrial” actually meant something. It’s a 4 1/2”, which I much prefer because cut-off and grinding disks are so much easier to find in that size, and there’s more variety. Paddle switch model before the safety interlock became mandatory on them. In other words, if I don’t set it down carefully, it can accidentally start up. The only service it has ever required was new brushes 3 or 4 years ago. Luckily, a local repair guy had the brushes, which are not standard.

I use it mainly for metal, especially cutting, but also for other materials. For a while I had matching (left and right) scars from using it without the guard, one of which has faded while the other is still faintly visible. I don’t recommend using without the guard.

HF makes a convex carving disk with big chunks of carbide imbedded. It’s reasonably aggressive without being a grabber.

I don’t have advice about what grinder to buy but you might want to check out this video about Sam Maloof. About 8:30 minutes in, you can see how they shape their rocking chair seats. They do most of the shaping on the band saw before glue up and just use sanding disks to shape the final contours. Seems a lot simpler and safer than trying to hog out a lot of material with the grinder. It also means that just about any grinder will work so you could probably find a decent one on Craig’s List.

Edit: more like 7 minutes in.

That worked for Sam Malloof, and it’s definitely allot faster,but it looks allot harder than just shaping after glue up of the seat.

LOL! I am sure that Sam got better with time. Remember that you don’t have to get it perfect, just close. You can sneak up on the rough profile and lay it out to see how it looks before glue up. Trim some off lay it down to see how it looks.

Edit: I think that you can buy plans that include the template for cutting the seats. A Maloof style rocker on my someday list.

I have a Makita and a Milwaukee. Both are variable speed. After using them, I won’t own anything but a variable speed.

Buying a variable speed grinder opens several doors. For example, I was able to slow the grinders down and, with a trickle of water on the blade, cut granite. Then I switched over to polishing pads and brought my cuts back to a polish.

I’ve used the Lancelot chain grinder quit a bit in the past. I used it with the side handle on and I advise you do too, if you go that route. While it’s obvious you need control of the machine, the Lancelot accessory is hogging off a lot of material in material that changes as you move across it.

I used one for remodel work and it fought with the occasional nail and many knots. Of course, that changes the game and affects what the blade wants to do.

I just remembered that LJ William Kappel sells plans has some great instructional videos on making them. Here is the one for making the seat.

If you send him an email (see his website), he will send you the instructions for free for making the chair with the plans that he sells.

I have two angle grinders. I can’t imagine using my full speed dewalt for sculpting wood. Instead I use my Milwaukee with variable speed. I use it at a very low speed.

The Maloof chair has been my biggest challenge as a woodworker. I highly recommend it. Here’s mine.

His website is still working so hopefully that means he’s still selling. In fact, it looks like he is still making and selling kits and finished chairs too.

Beautiful chair, by the way.
