Yes mate, your advice was noted. However, when at the shop, I looked at the fine mat and it looked a little too fine. I want the glass layer to be sturdy and long lasting. The shop and I calculated the amount of resin needed, and factored in a little bit of spare. Obviously something was amiss. Never mind. Its only short by a couple of square metres.
Even now that over 90 percent of the dome is covered, Im looking at it thinking I would have liked it a little thicker. I might get a nice thick layer of tinted flowcoat yet. either that or lots of layers of paint. This will UV protect the glass and also fill in any fine holes missed in the glassing process.
As far as flex is concerned, because I used little polygons in the apex of each triangle to join them on the inside, the thing is more rigid than john holmes platinum edition.
I took your advice and used less catylist to give me more time and that worked a treat mate. Thank you.
The castors were old and kept binding. They were also very noisy and squeaky. I enjoyed making a little more professional track and turned rollers anyway. Later Im thinking of spot welding motorcycle chain all the way around on the inside of the track, then installing a small electric motor in the wall with a sprocket fitted and a forward/off/reverse switch on the wall.
