I've been working on re-creating a classic Doctor Who series roundel from scratch, and finally making some progress. I am looking for advice from experienced fiberglass (GRP) members. The problem I am having is air bubbles being trapped between the surface veil and the mold. Sometimes these...

Some progress has been made. I'm working on making some subtle changes to the former that should improve the profile accuracy. A V2 plaster roundel was created with the old former, and it could be use to make a mould. I'm going to wait and see how V3 turns out before making any moulds since...

Here are some pictures of the plaster roundel and brass former that I used to make it. This attempt came out rough in places, and the plaster never got hard on the surface. This is probably due to a combination of bad plaster and the fact that I was having to mist water on the surface to keep...

I tweaked the drawing a bit to make it more accurate to Purple's measurements. The result is a slightly deeper roundel than previously posted. Updated dimensional drawing: Here is the finished product, as close I can get it to the known measurements. Here is a link to the final Google...

Well, they are very close to Purple's drawing but not 100% exact. Here are the measurements. I can tweak the drawing for you if you like. Just let me know what you want changed. I also hollowed out the thicker parts of the drawing to maybe reduce the cost of 3D-printing. I'll post the final...

I based the roundel cross section on the graphic that Teletran posted over at the TARDIS builders site. Then I traced the graphic using lines and arcs to get a solid cross section in Google Sketchup. Then I extruded the cross section into a circle, and here is the result. Well, it's...
