This is my Flatmaster sander. I purchased the 18” x 2” kit and built the case with MDF that I had on hand. The top was from some pre-laminiated extra wide shelving that I bought at Home Depot. I added aluminum angle for support and some t-track for a fence. The motor I spent just a bit extra to get ball bearing motor, it is 1/2 hp, which is plenty for this application.

So far, it is running well. I will need to try it out on a project next.

Hi, any updates to your post? How do you like the unit. I’m considering buying the 18” or 24”. What made you decide to get the 18”? Thanks in advance.

I have had a chance to use it on a tumbling block end-grain cutting board, which is about one of the toughest things I have had to sand. My first one (prior to having the flatmaster took hours of sanding). The flatmaster worked well, but is not very aggressive, it takes a number of passes and maybe 20-25 minutes of sanding. I only had 100 grit sand paper on it. I have just ordered 80 grit and even 60 grit that I can use for something like the first pass on a cutting board or if I have a board too wide for my jointer. I have found that many passes are needed with other items that I have passed through it, it works best with light/multiple passes.

I typically make small projects, so I thought the 18 would be enough. Having wider would be good if you are doing panels, but I figure I will seldom having anything that wide. However, the 4” over the 2” might have been a better decision and would have allowed for a quicker feed rate. Still, I am happy with the unit. I did make a stand for it that has some shelves in it for storage. I have yet to make the fences for it, but I do think it will work fine for edge sanding too.

Overall, it is probably not comparable to $1000 drum sander, but for about $350, it is a good sander without a lot of the hassles that you can have with a drum sander. Changing paper is simple and so far, I think I would agree with others that the paper seems to stand up well. I think this is a very good option for a hobbyist. I have also heard that this is a good option on delicate work too, which I can see.
