Jimmie,
Another 2 cents worth - you could try something like "Bondo" which is resin-based body filler. - Pick it up at Auto-Zone or other Auto parts place. But well-coated wooden blocks may work ok as well. I would try to find a way to use a PVC fitting to save money. Hal W4PMJ "JIMMIE" wrote in message ... I came across an old single LPDA TV antenna in the trask. It was pretty much FUBAR except for a coupe of feet of boom matrial and a few insulators. My XYL is into making models and castings and she can make a mold of the insulators easy enough. I was wondering if anyone knew of a good casting material that would be compatable with the requirements to build a single boom LPDA antenna to form the insulators. She is not usually concerned with strength or UV resistance so she couldnt help much on this part. Jimmie |

Hal W4PMJ While Bondo is based on an unsaturated polyester resin, it uses lots of styrene and filler materials. Both destroy the inherent strength of the polymerized polyester. Stick with a high quality boating resins and use fiberglass for strength. 73, Dr. Barry L. Ornitz WA4VZQ BLOrnitz84@charter/net [transpose the digits to reply] |
