  1. So I recently removed my skirt plug from the mold, and while everything came out fairly well, upon closer inspection, I noticed several dark spots in a sort of fractal-ish looking pattern. Some them were only discoloration, but some of them were actual distortions in the gelcoat. The best way I can think to describe it is that it looks like a bunch of little mountains and valleys. Ive attached photos for reference. What exactly is this? What caused it? I know for sure that the surface to which I applied the gel coat was flat and smooth, and I know nothing got underneath there as the gel coat was curing, so how did these distortions get there? What caused the discoloration? Is it some kind of chemical reaction or release/build up of gas underneath the gelcoat? I know its not physical damage, because the gelcoat isnt broken or chipped or anything; these distortions are perfectly smooth. Meaning, the gelcoat cured with these little mountains and valleys already in there before it dried. I dont think the distortions are too too bad. I should be able to fill them in with a little more gelcoat and smooth it over fairly easily. However, Id still like to know what exactly is causing this phenomena so I can avoid it in the future. I figured someone else on here must have experienced this at some point, or at least know what it is. Can anyone clue me in as to whats happening here?
  2. Well, I havent had much time to work on Mordin in the last month or so. Moving from one side of the state to the other and working on finding a new job has taken up most of my time. Honestly, the biggest thing is that my new place in Philly doesnt have a garage or a yard or anywhere to work on or even store the Dalek. Luckily, I still have use of the garage at my old place in Pittsburgh for at least the next few months.Im basically going to be taking my weekends and any consecutive days off to drive 5 hours back to Pittsburgh to spend a few days at a time working on the Dalek. That said, I did manage to get a teeny bit of work done this past weekend. Basically just removing the Skirt mold from the Plug while I was gathering everything from the shop to take home and put in the garage. The front half came off easily enough, but rear half REALLY didnt want to come off, so I ended up having to slowly extract it using ratchet straps. Seems like it turned out pretty well.
  3. Back from the shop, and I managed to get 3 layers of fiberglass on the fender, and one last layer on the second half of the skirt mold. Next time I head to the shop I should be able to de-mold the fender and see how the final product turned out, as well as removing the plug from the skirt mold and getting the mold ready for making the final skirt piece.
  4. Well, got the first few layers of fiberglass on skirt mold. Gonna be heading back to the shop later tonight to add the last few layers. Also started casting the Fender; got the release agent sprayed on and a couple nice thick applications of Gel coat. Next up is fiberglass, and Ill have myself a fender!
  5. After finishing the front half of the skirt, I realized that a ton of resin, gelcoat, and release agent had all dripped down onto the back half, leaving the top and bottom back half of the skirt looking like someone had dripped multi color candle wax all over them! I didnt get any pictures of it because I was so annoyed, but you can sort of see the drips in the first picture of my last post. It was a huge pain, but I managed to get it all scraped off without any damage to the skirt beyond a few scratches, which I then remedied with an orbital palm sander. Here's what it looked like all nice and cleaned up. I also removed the two 'fins' that I fitted to the skirt so to make a seam for the 2-piece mold. Im pretty pleased with how the fiberglass underneath came out so far. After this, it was a few coats of polishing wax, and then on to the release wax. After that, a nice thick coat of PVA release agent. Once that dried, I applied the gelcoat. I wasnt able to get any fiberglass onto this half just yet, as the gelcoat was still far too wet (not just tacky, but still fully liquid in some places) and the shop was going to be closing soon. Im going to be heading back to the shop as soon as it opens tomorrow morning so I can get at least a couple layers of fiberglass on there. That way, even if someone bumps it or some such, it wont damage the gelcoat. I also managed to get the fender mold finished up. It had a few little pits and divots here and there that needed filling, and the whole thing got a good sanding to make sure it was nice and smooth. There was also the raw fiberglass on the inside of the hole that wasnt covered by gelcoat, which I trimmed off with a jigsaw using a special blade made for cutting fiberglass. (but not before completely burning the teeth off of a normal jigsaw blade because I didnt want to have to stop and make a trip to the sttore) The fender mold is basically all set to cast the actual fender. I probably wont have a chance to get to it till next week (I wanna get the skirt mold dont first. I dont like having the raw gelcoat exposed like that since it could get damaged while its not protected by the fiberglass) but once the skirt mold is dont, Ill be all set to apply the release wax and release agent to the fender mold, and then onwards to more fiberglassing!
  6. Welcome to the forums! Or I guess I should say welcome back? XD Let me know if you need any help locating good sources for materials.A few of the things commonly recommended are a bit hard to find in the states. What kind of Dalek are you planning on doing?
  7. Welcome! What style of Dalek are you planning on building?
  8. Havent had a chance to update recently, but I managed to get the gelcoat applied to the front half of the skirt, and then applied a couple layers of fiberglass before the shop closed. Went back a few days ago and got another 3 layers added, for a total of 5. Debating on whether I should add a 6th layer, or just move on to starting the other half of the mold.
  9. More progress! Took some 1/2" MDF and cut it to fit around the edge of the skirt to make a pair of 'fins' that will let me make the 2-piece mold. Clamped them on with some bar clamps, and got to work waxing, waxing, and waxing some more. Got 5 coats of polishing wax and 6 coats of release wax put on before moving onto the PVA release agent. The release agent was applied with a cup sprayer, and I put it on a little thicker than I did with the fender. In between coats of wax, I also managed to remove the fender plug from the mold! It took some doing, but the mold came out great, and the plug is almost entirely intact. After removing the plug, I went to clean the film created by the release agent, and while it peeled off nice and clean in some places, it took some scrubbing and buffing in other places. Thats why I applied the release agent thicker on the skirt; I figure if its a nice, thick, solid coat, itll be more likely to stay in one piece and peel off, rather than just tearing every time I try to peel it. Hopefully the skirt mold wont require as much scrubbing when its done. As you can see, the plug did suffer SOME damage while being removed from the mold, but all in all Id say its still in great shape. Will a little cleanup and a little repair, Ill have a nice spare fender lying around in case Conrad's ever breaks. Ive got some things to take care of Monday and Tuesday, but Wednesday I should be back in the shop and getting the gelcoat and fiberglass on the skirt, as well as starting to prep the fender mold for making the final product. Cheers!
  10. Got the final 2 layers of fiberglass on the Fender mold. I realize the top layers are pretty ugly and have a lot of bumps, but I believe the inner layers, and more importantly, the layer contacting the gel coat, are all nice and smooth. The last layer or 2 was just kind of a rush job due to time limitations that day. Next up is starting on the polishing and waxing of the skirt, then release agent, gelcoat, and onto fiberglassing the skirt!
  11. This is pretty much correct. he dimensions listed in the plans are the outside dimensions. The inside dimensions would then be the outside dimensions, minus the thickness of your material. Keep in mind though, that your motor frame doesnt have to be a perfectly snug fit to the exact interior dimensions. Take a look at this post from my build diary. It should give you an idea of how you could approach it.
  12. Plywood or MDF are pretty much the standard choices. Thats not to say that no other material can be used, but these two offer the best combination of weight, strength, availability, affordability, and how easy they are to work with. Also, as for fitting a sheet of plywood in your car, I had the same issue. I have a prius, so theres no way in hell Im fitting a 4' x 8' sheet of MDF back there. What I always do is figure out what the largest single piece will be, and cut it to that size before I leave the store. For example, for the fender, the single largest piece of wood would be the 'top' of the fender, which all the angled side pieces then attach to. This piece needs to be 88CM by 119.6CM. Since your local store has plywood sheets in 120cm by 244 cm, I would just have them cut the board at around 90cm down the legnth of it, so you end up with a piece that is 120cm by 90cm. This would be large enough to cut the top piece of the fender from, and also small enough to fit in a lot of cars. Then, just cut the rest of the board into a few smaller pieces, and it should all fit.
  13. Others may have better suggestions, but as far as I know, the best/easiest thing to reinforce fiberglass with is simply more layers of fiberglass. Keep in mind that entire boats are made of fiberglass, and they stand up to people walking running and jumping all over them. Fiberglass can be very sturdy when built up enough.
  14. I could be mistaken, but Im pretty sure that that slider is for notifications on the forum itself, not via email. When you log onto the forums, theres a little globe-shaped icon in the toolbar for notifications, right next to the 'messages' icon. I believe that this is where that slider sends notifications of replies to.
  15. Managed to get the first two layers of fiberglass done last night, but had to stop because TechShop was closing for the night. Went back for a few hours today and got 2 more layers added on, for a total of 4. Im honestly considering doing a 5th and even 6th layer when I get back in the shop next. XD I want this mold to be very, very sturdy. The first two layers I just used the resin on its own. Then for the 3rd I added black pigment, and then yellow pigment for the 4th layer. This is just to make it easier to distinguish the layers and see any spots I may have missed.

      Looking for the close up photo of the portable graphic equaliser deck that Nick Briggs use's with his Moog MF102. Somewhere out there, I have seen this photo of him sitting at a table with the graphic equaliser, to fine tune in the sound of the Moog. Could be used as a reference photo if allowed on the Forum.

      I finally received the Workshop Manuel today! Now all I have to do is study it. Hopefully I'll start a build diary by the summer.
