It's made from 5/16" steel tubing that I had laying around. Took about 5 minutes to make. The tip is relatively easy to shape so there is any design you may please to be had.


#129454 Tip Size For Hvlp Spray Gun

Since you are just getting started with spraying, you might spend a little time getting familiar with the various controls for liquid volume control, air volume control and input pressure. While I haven't tried spraying glazes yet, I have worked with lacquers as well as latex and acrylic paints for painting cabinets and other woodwork. You may find it necessary to increase your input pressure to handle the thickness of the glaze you are spraying. Another option is to thin the glaze to a consistency that makes it easier to spray, but may require more coats to get the ultimate effect you are striving for.

It may sound silly, but you might consider mixing up some pancake batter (using water instead of milk to keep costs down) to practice with. Buy the pancake mix at a dollar store.

Another option would be to get some latex paint that has the consistency you are working with. Here you would ask the paint clerk to open various types of paint to check their consistency, then check to see if they have any mismatched cans that you can buy for less money. If you go the paint route, get a gallon rather than a quart, it's a lot cheaper in the long run and will give you plenty of material to practice with.

#126706 Qotw: What Do You Listen To While Working In The Studio? Music, Tv, Talk Radi...

Posted by JohnnyK on 15 May 2017 - 09:21 AM

Usually talk radio...until I start yelling at the radio. Then I switch to an Oldies station or throw in a CD where I have total control. I don't like to anything in silence except read.


#126477 Economical Source For Splash Pans And Supplies?

The grooved ring around the top of the pan is a piece of plastic wire harness used to cover the sharp edge after you cut the trash can. The duct tape helps stiffen the pan after the cutout. 

I designed the pan to make clean-up a little easier since I believe the manufacturer's pan was just a shield rather than an actual pan. The black trash barrel was bought at Home Depot but should be available at any hardware store. The riser was a smaller utility tub bought at Dollar Tree and cut to a height that would contain the shavings from the GG.

If you've been making these pieces for awhile now and have been satisfied with the product, why change now?

#123741 Can Unglazed Pieces Touch In Cone 6 Firing?

Love the pieces...particularly the metallic!  What kind of paint are you using. I have some acrylics that are designed for automotive use and cure under heat (like a heat gun).


#123343 Marking Up And Using Holes As Decoration

Posted by JohnnyK on 06 March 2017 - 09:00 PM

Hi and welcome juliad,

Since you are into slip casting, are you making your own molds? If so, are you doing the same carving on multiple pieces? If so, you might try laying out an accurate pattern and carving your pattern lines with a sgraffito tool. Then you can make a mold of the carved piece. When you cast your new pieces, the carving lines will already be layed in, providing you with the guide you need to finish the carving. Good luck!


#122429 Propping Kiln Lid

Posted by JohnnyK on 17 February 2017 - 10:34 AM

I reused the screws that were holding the handle on the lid when I switched them.  If they are too rusty to use go to a hardware store and buy some replacements, don't forget to take the old one with you for comparison.   Denice

If You replace rusty screws, do so with stainless steel. They're a little more expensive, but they're stronger and won't rust.


#122164 Hummingbird Feeder Spout Placement

Posted by JohnnyK on 12 February 2017 - 10:55 AM

My wife & I made and sold these feeders and didn't have much of a problem with juice leaking out.

Since your cork is tapered, I would suggest that you make a test strip of clay about 2"x6" and the thickness of the globe feeders you are making. Because the clay will shrink in the firing process, you should cut multiple holes in the strip that range from about 1/8" larger in diameter than the small end of the cork  up to the largest diameter of the cork in 1/16" increments if you can.

 Bisque fire the piece; glaze it and glaze fire it as you would if you were firing your globes. I would not glaze the inside of the holes because the glazed holes might be too slick to keep the cork in place. The finished test piece will give you a range of hole sizes to work with.


A photo of your globe feeder would help for suggestions on where to put the hole.

If you live near enough, you might just go to the plant and talk with them personally, bring up the issues you cite here, and get their input.


#122043 Why Is This Happening?

Posted by JohnnyK on 10 February 2017 - 02:00 PM

Regarding your inability to center...I had that problem until I tried centering with my eyes closed. If your hands are in the right positions and the clay is close to centered when you place it, you will be able to feel the clays reaction to your efforts with closed eyes. It was fascinating the way it worked the few times I tried it. After blind centering four or five times, I have gone back to centering with open eyes and haven't had a problem at all.


#121832 Vertical Heat Clearance

Posted by JohnnyK on 06 February 2017 - 12:07 PM

A downdraft vent won't have any effect on heat coming off the kiln. It only vents fumes. Even in a basement with 'low' ceilings, the clearance between the kiln and ceiling is not an issue from a safety standpoint. If you can stand up in the basement, then it's fine. The bigger issue is heat radiating through to the floor above. Depending on the size of the kiln, the room above the kiln can be noticeably warmer from the  heat of the kiln. To help that, you can put a layer of cement board on the ceiling above the kiln to help block the heat, and also keep some fresh air moving through the space with a fan. The best solution to deal with kiln heat is a vented hood above the kiln, like those made by Vent-A- Kiln. The hood also vents fumes. They're pretty easy to install, but more expensive than a downdraft vent. If you have a window near the kiln, a fan in the window can do a good job of pulling out heat.

The cement board works even better if you install 1" spacers between the board and the wood joists.

It's been a long time since I ran a gallery, but you may check to see if 1) the gallery has insurance to cover this event; 2) the deductible is not unreasonable to where it wouldn't be feasible to make a claim. Otherwise I agree with Mea.
