In Topic: I Need A Finished Product With 3/8" Mounting Hole?

26 August 2015 - 10:10 AM

I think making a shrinkage ruler for each of the different clays you use would be ideal but, instead of 10cm which is only about 4", I would go with 10 inches (25cm). It would be easier to read and calculate the shrinkage. As far as the hole size...there are a couple of ways to go about that but all of them are just starting points until you know exactly how your particular clay body is going to shrink. Your primary consideration would be your boring tool and when you bore the holes. Will the clay be leather hard or bone dry? Leather hard would be easier to work with because bone dry clay is very fragile. What is your drill bit repertoire? What sizes do you have over 3/8"? Try 7/16", 1/2" and 9/16" and see what the holes shrink down to when fired. If one of them works, you have your working tool. Another option would be a 3/8" diamond boring bit to drill the hole AFTER the firing. With that, you'll have the exact size hole you want. You would want to drill those holes using a drill press and jigs to hold your work piece.

In Topic: Diy Sieve

any one make diy sieve?


i want to start with making one for dry ingredients   approx 40 mesh


welcome any ideas

Just last week I was thinking about making my own sieves after looking at the prices of off the shelf units. The problem with the source I found is that I would have to buy 15 square feet (3'x5') which is definitely more expensive than store bought, particularly since I would like to get 60,80, and 100 mesh screen. I have an idea on making the individual sieves using PVC fittings, but that might wind up costing as much as store bought sieves.

Attached are a few pix of the ceiling fan banding wheel I spoke about earlier.

I've purchased a couple of fans to use for the video I'm going to shoot on the fabrication process, but the video will be done as soon as I recover from my recent hand surgery. (That will be in about 2 months.) After  you look at the pix let me know if you have any questions.

I'm still checking on a way to power it for the spray booth application.

In Topic: Magic Box Damp Box What A Type Of Plaster?

12 June 2015 - 10:02 AM

I used pottery plaster in my box when I put it together about 2 years ago and added about a quart of water after the plaster set up. As an experiment, I placed 2 mug bodies and a large sycamore leaf in the box and closed the lid. I looked in on my pieces after about a year and the mugs were as moist and pliable as the day I threw them and the leaf was moist too. I am in the process of converting a small studio apartment into my clay studio and the box was moved to the studio to get it out of my garage. At the 18 month point and occasionally since then I've checked on my pieces to find them in the same pliable condition. I got rid of the leaf because it was getting moldy. Since I started the experiment, I've added only another pint of water to maintain the humidity level. My box is about 30x15x15 and has about 1.5" of plaster in it.

The studio has a shower which I was going to convert into a wet closet, but after working with the box, I think I might just put some shelves in it and stack some damp boxes instead.

Sorry ... Don't know how to use quote correctly!

JohnnyK ... I'd like pictures/video of your ceiling fan banding wheel. Thx!

I'll take some pix of the finished unit (since it's already built) and post them later this week. The video will have to wait awhile. I'm looking for another cheap fan so I can document the process from start to finish. The fan that you get has to have a downrod because the outer housing is used for the base. A "hugger" fan won't work for what I did.
