Hello,
I'm looking for some suggestions as to what size would be appropriate for both the square and the circle tube for a production box. The load I am looking to produce is actually a drum. It is 16" tall by 10" diameter. I will be performing in a venue that has the audience graduated fairly severly. It won't be a balcony but I will have to content with angles. Thus, what are your suggestions on the sizes of the apparatus? Also, what do you suggest building the decorated tube as well as the black art tube from? Many thanks. Amazing Carrington |

Depending on how easy it is to grip your load, I would make the device just a wee bit bigger. If you need a grip on the side or something, then larger is the way to go. If the audience is above you and looking down, this will kill the gaff very quickly, hav ehte table angled a bit, so the upper seats are still looking at the box face on

Cliff,
Thanks for the suggestions. The angling of the table is a great idea. Regarding the load. It is quite heavy....a ceramic drum. Thus, I'll need to leave it on the table under the gaff while showing the square and circle separately. Any further suggestions are appreciated as I hope to make this in one shot and not have to experiment too much. Also, still curious as to what to use for the tube (circle). Obviously just a sheet of metal curved and soldered. But was wondering about wood...bending some thin wood. All the best. Michael |

Stove pipe comes in various diameters and can work quite nicely. Line the inside of the box with the best black velvet you can afford and wrap the outside of the inner tube in the same. It produces the best black art effect. If fearing view from above line the inner tube inside and out with the velvet and wrap it over the top edge. Line the inside of the outer tube, also. Also, sheet metal fabrication shops can probably make you the tubes for a reasonable price if stove pipe is not large enough.
Build the outer box out of 1/4" plywood glued and reinforced with 8 L-brackets top and bottom at each corner. Cut the large open pattern on the front and back it with a reflective screen of some type. There are types of the used on radiator covers with various open patterns. The reflection of light off of the screening makes the black art more effective.

Hello Evangelion,
Hey.....thank you so much. I had entertained the thought of covering the top with black and now after hearing your same comment I feel much more confident about it. Plus....thanks for the building tips. Your comments are above and beyond and very much appreciated. All the best. Michael |

I would to sheet metal shop and have them roll the tubes out of 28 guage metal and wire or fold each end for more strength. The 1/4 plywood box as suggested is the way to go. You can paint it, cover it with sign vinyl or fabric. Make the load tube at least 1/2" small than the tube. It makes it easier to to the transfer. The box should have a similar clearance.
I can make the tubes if you cannot find someone local but then we have the cost of shipping them. I would think that you could find someone local. I don't think I would bother with the angled table. If you cover the load with black silk or felt it will be invisible. I work in balcony situations and do this all the time. There is no depth perception this way. Richard

I agree, Hugh, simply using a black silk or felt on top will solve the problem from above.
The reason black velvet works best is the fibers are perpendicular to the length and breadth of the material and this makes it very low in reflectivity. Light enters but any reflection is away from the line of sight perpendicular to it. Felt and flat black paint are other options, but velvet with attention to wear from burnishing by friction just eats up light.
