| Post subject: | $120 Powered Radius Dish Sander |
I've been thinking about how to build a powered radius dish sander for awhile and came across a picture of someone using a pottery wheel. I found this one for $120.52 (shipped). It works great. 0-360 rpm. I tried a couple of different mounting methods. In the end, I fabricated a round block with a 1/4" hole in the middle. I drilled a 1/4" hole in the center of the pottery wheel and used that as an alignment tool for the radius dish, which also has a hole in the center. Then, I used the blue tape and superglue trick. I was unsure how it would hold up, but it works great. I then drilled three holes in the bench and set the legs in holes. I screwed some blocks underneath to space it up a bit. This lowered it and holds it in place. The whole project took about 2 or 3 hours. I'm actually really impressed with the pottery wheel's quality. It's pretty heavy. I don't know how they can sell it for that. It even has a digital control. Here's a review. https://www.youtube.com/watch?v=3bDB_NDn72o The woman in the review gives out the discount code 'Discount23.'

The picture of the inside guts of the machine shows what it looks like with the bottom removed. I wanted to see what was in there. |

Nice! Can you elaborate a little bit more on how you attached the dish? I can't quite follow. Super glue? Sent from my SM-N960U1 using Tapatalk |

Did your wheel bog down at all with pressure? My dishes weigh in at 11lb 12 oz. Looks like a great method. |

Sent from my SM-N960U1 using Tapatalk I put blue tape on the pottery wheel dish and I put blue tape on the back of the radius dish. Then I put medium viscosity superglue on the radius dish tape, and I sprayed CA kicker on the radius dish. Then joined them. It holds fine for me, but still comes apart by lifting up. It’s the same way I learned to cut abalone on my CNC. The key is to get the radius dish centered properly. That’s why I made the round plug. I drilled a .25” hole in the center of the pottery wheel to use for an alignment pin. I put a .25” hole dead center of the round plug and mounted it dead center of the pottery wheel with the .25” pin. My radius dish has a hole in the center that perfectly matches the round plug. At first, I tried a different mounting method, but it was misaligned and caused vibration. Now there is no vibration and it runs smooth. |

It was a set of sides that I messed up so I wasn’t concerned about it. I didn’t push super hard, but I didn’t need to - just light pressure was all that it needed and the sandpaper did all of the work. I chalked the rims to see how well it was making progress, and it was certainly much faster than when I do it by hand. The only downside is all of the dust that would normally fall to the table was getting kicked up into the air and it was definitely kicking up a lot of dust, I have a large air filtration unit on the ceiling right over where I did the sanding, so it wasn’t too bad after a little while. I have an air quality monitor and the shop always settles down to an acceptable level in an hour or two. |
