I am tagging Jugglerguy (Michigan Rocks Youtube). In Rob's last video he mentioned that the diamond dry grinder he uses is from Harbor Freight. He didn't mention who manufactured the wet grinder he uses. Kingsley North also has a wet grinder that I am assuming is made for them. Below is a link for that. Looks like it is about the same price. kingsleynorth.com/lapidary-wet-polisher-grinder.html

I have 3 wet grinders and just set up an area to start playing with them, I have a Secco 4" that I got brand new a few years ago at a garage sale. I tried it out on a practice piece of Petwood a few days ago and was happy with the grinder, and after a few more tries I will hopefully be happy with my work... I have a used 5" Damo that seems pretty robust as well, but needs the water lines unplugged. I suggest using an inline RV water filter, especially if you have hard water. That should keep the calcium to a minimum. I think the KN is a rebadged Damo, they are identical in shape. I also have a BD air operated one NIB that I will probably end up selling, it requires a large air compressor to run, and I don't want to fork out a ton of money for that. My "practice" so far tells me there's a learning curve, and that I need something water resistant that will keep the pieces from moving. www.amazon.com/SECCO-WV5GRIN-5-Inch-Wet-Polisher/dp/B001KAMAMAwww.amazon.com/DAMO-Variable-Polisher-Countertop-Polishing/dp/B07CV9H4M8/ref=asc_df_B07CV9H4M8

In the video below, you can see how rob uses wood blocks to help keep the rock in place when grinding.

I've been planning on making a piece of plywood with different size holes cut in it with hole saws. Clamp that in a work table to polish thundereggs. I got a Barranca Diamond grinder that works well. I picked it up for $20 at a sell. Considering it has a couple sets of diamond pads and a couple of hard grinder heads, including a never used one with a $115 price tag still stuck on the face of it I think I did pretty good.
I don't know anything about the HP model you linked. It looks like a pretty good deal. I would look at the tool alone and buy the diamond pads elsewhere. Unless those are some great quality pads they are pretty expensive.

Actually the HP branded unit looks very similar this one. The first thing I noticed on the HP was the water line coming in the top. I think I'd prefer it underneath.

I have a regular Makita angle grinder with a diamond cup wheel from Harbor Freight. I also have a Makita Electronic stone polisher that I use with velcro diamond pads. I like both of them.

In the video below, you can see how rob uses wood blocks to help keep the rock in place when grinding. - The addition of wearing waders is SPOT ON! I sometimes feel like I need a wetsuit just using the trim saw.
- The wood braces are a nice addition, I kind of wonder if a setup of two "L" shaped 2x4s interlocking and some memory foam underneath it to hold what is being grinded might work.
- I wouldn't have thought of doing a dry/wet grind on a large rock like that. I have a regular angle grinder which would work well for that part but that wet one he has looks like a decent set.

here's what I used so far, table came in an estate. Unfortunate that I just did a burn barrel last week and all the 2x4 scraps went in. ![](https://res.cloudinary.com/rockoonz/image/upload/v1716503360/im5ffnuedzbbu8f4n7rj.jpg)
