  1. Well another update. The bagging consumables have been applied..... So in there now is polyester peel ply, infusion mesh (400mm at each end), and vacuum connectors with infusion spiral at the uptake end. A new bag has been applied, as the last one was made of two pieces with 6 joins. I left the old outer bag on though for added puncture protection. The new bag is single piece with one join at one end...... The drop test seems to be holding up, however I think there is a slight leak at the catch pot. The infusion spiral also need a slight reposition to get it back on to the mesh. Just tweaks here and there, and the resin goes in asap. Have a nice weekend folks!
  2. The innermost skin is now in..... If I manage to get back on Friday, then it is full ahead with the infusion bagging materials Saturday morning/afternoon, and infusion Saturday afternoon/evening. I think I may have bridging issues though especially with the innermost materials. If so it makes life more difficult when it comes to installing the rear cell.
  3. First layer of inner skin is going to be laid in four overlapping segments. Here is the first one..... All of the segments are now in, and looking good. The final, and innermost skin I will put down in one piece, so only one edge is visible. This will give 2/3 inner skins. Should be enough I think. All being well, I think we should be looking at next weekend for an infusion.
  4. The core material is in. This is 3mm 3D CORE PET 100 Foam......
  5. So, continuing with the first attempt after all. Vacuum bagged to attempt to de-bulk the outer skin, so I can cram in the core material, then the inner skin. Images:
  6. MBJ, can you post a pic of the SW diagonal?
  7. OK, so the first layup attempt didn't work out very well at all. I managed to get the cloth into the mould but it was a bit of a shambles. On hold for a bit until I do a bit of head scratching. Current thinking is to use a single, heavyweight (650g) sheet for both the inner and the outer in order to simplify and rationalise the layup. And possibly give the mould a spray of epoxy compatible polyester gelcoat in conjunction with a spray of acetone on the inside surface of the cloth to tack it to the mould. Yes, plenty of options. Spraying the mould will require some warmer weather, in the mean time I am going to step back for a bit and have a think about the best way ahead.
  8. External formers completed. The roundness is very good now, I think it may have been out more than I thought, so I am glad I did that..... Cutting the cloth has commenced. Just to be a bit different the outer laminate is going to be a combination of carbon plain weave and carbon/kevlar plain weave (this may go part way to overcoming brittleness Rusty?). This is very difficult to achieve with any semblance of professionalism or neatness, so I am either being very brave or very stupid. Quite probably the latter. At least it will be interesting if nothing else.....
  9. Thanks for the replies chaps. I may just get a small pelican case and build up a little set.
  10. You know those clear plastic twist cases that people store eyepieces in? Where can I find them please?
  11. Second the toolchest. You might get a good deal at hellfrauds at this time of year.
  12. Wasn't there a period in the 90s(?) where there was a high level of ball lightning activity in at least one mountain range in South America, that usually preceded seismic activity?
  13. Speaking of doing things on a grand scale......
  14. Have commenced adding the external formers to the mould. These are ply/styrofoam/ply, and will be glassed over.
