  1. You don't need to go that far with it Chaz. You just need to get the pressure down a bit so the resin sits all the way down into the mold properly you could probably get the pressure down enough by sucking it out yourself without needing a pump. If you fit a plastic pipe, when that starts to collapse as you suck that will probably do it. You only need to get it down to around 10 lbs or so and it only needs to be for as long as it takes the resin to set. Getting anywhere near a hard vacuum would take serious engineering. A heavy blanket isn't a bad idea though. Safety first and all that. In fact you would get better casts just by vibrating the air out of it instead and it would be a whole lot safer, all you would need is a bit of board, four rubber feet and a multi tool and you have a vibrating plate. It don't need to be pretty it justs needs to vibrate when you touch the multi tool to it. Just stick the mold box to it with blue tack and shake it down for 30 seconds or so and your casting will improve. Regards Lez.
  2. Best thing to do would be to make vacuum chamber Jamie. It's not that hard to do if you think about it. It don't need to be a total vacuum a partial one is enough. Get a big glass jar, a carboy type of thing and cut off the bottom. Now find something to make a seal and fix that down to a base then get a big cork to go in the hole at the top with some sort of pipe in attach a pump and pump out the air. It don't have to be fancy and don't have to be pretty all it needs to do is lower the air pressure a bit and you will get much better casts and you will get better molds if you do them in there as well. Regards Lez.
  3. Green is so the right colour for that 21. It is a 21 and not a 29 is it not? Two tone looks really odd on them but plane green is fab. I also liked your solution for the roof. Very nice mate. You could also have made it from a turned solid if you have access to a lathe or a Christmas tree ornament. Regards Lez.
  4. Anthony, that's just fabulous! I agree that the brick arches need that edge coloured but that's no big deal. Well done mate it is indeed outstanding. Regards Lez.
  5. Oh well the answer to that is easy Les. You lay the tape first then fit the diagonals. Regards Lez.
  6. Hi Gordon. I have a 1/16 scale Tiger 1 that shoots airsoft plastic balls. It shoots them very very hard. The ammunition comes in plastic, steel and paintball. Won't kill the thieving bird but it will give it a nasty fright. Available on ebay for not very much money and available in different models if you don't fancy a German tank. I don't have a heron problem, I don't think they can land on my patio and I've hidden my pond under a parasol so they can't see it. All they can see is workshop roof, parasol and flat. I do have a seagull problem but I have a net frame I lower when no one is outside and at night. I also have two cats who don't fish but do bird! The cats and the fish interact with each other too which is quite fun to watch. One of the cats has big webbed feet and loves water but they see the fish as part of the family not food. They see birds as food and will go for them but mainly bigger ones not little birds like robins or wrens. They get interested around blackbird and starling size and and will go for bigger birds like magpies and crows, they look on big birds as a challenge. My Koi are getting too big for my pond but it's an above ground job and I've just ordered a bigger one so I have to rebuild the net frame and get a bigger parasol. Regards Lez.
  7. The way to go with diagonals is to drill them with a big hole hole cutting saw. The same way you would when reliving weight. Just pop 5 or 6 40mm holes in each one before you fit them and the jobs a good un. Downside, it's a pain in the backside. Upside, it saves weight and makes wiring up easier. Regards Lez.
  8. Yes Jonathan. The plinth is not 4 sided. on some of the coal houses and a track ran through the "bridge" or even if that's wrong there was track either side of it for sure. They loaded the tubs at ground level and lifted them up with the hoist and into the tenders or bunkers and then picked the empties up with the other hoist and lowered them onto the track on the other side of the platform and then filled them from the coal wagons the other end of the building. Even if that isn't quite right it was something very similar or the whole concept is unworkable. In LMS engine sheds volume 2 there are enough pictures of that type of coal house to be able to piece together how they worked them. If you do it this way you can run the whole operation with just 4 tubs but you can figure out how many they used in any given coal house by the number of "bays" the buildings have each side of the hoist. Buxton had two bays each side of the hoist platform as can be scene from lots of pictures of Buxton shed. It is very similar to the one at St Albans shed. The only real difference is Buxton is built from stone and St Albans is built from brick, both from the most abundant local building materials. St Albans is only around 15 miles south of one of the largest blue clay deposits in the UK and Buxton is right in the middle of some of the largest limestone quarries in the UK. I'll have a look over the weekend and see if I can find this drawing for you. Regards Lez.
  9. That's quite an elegant solution your "door/swinging cupboard"- whatever you want to call it thingy. Very nice mate. Regards Lez.
  10. I do like the coal house Jonathan. You have definitely captured the essence of that style of midland coaling facilities. Are you going to add the narrow gauge track and coal tubs? I do believe I have drawing of the tubs somewhere. It's in one of the midland records I have or in midland style I'll have a look for you. If I don't then Dave Hunt has either got one or access to one. Regards Lez.
  11. Nice work on the 120 Jamie. The work for the 124 is inspiring, the conversion kit has been in my watch list on ebay ever since it first appeared, but you do know that as soon as you finish it Bachmann will announce it as their next big dmu project don't you? It's been on the big wish list in the sky for years now. I have plans to scratch build a DF Kirtley and I know as soon as I start cutting metal London road will bring out a kit for it. It's been rumored for 20+ years now and if they can do the Midland railmotor they might just finally do it and save me a lot of work. I know there are two options but neither of them are good options, The K's kit isn't that awful but the prices they are achieving are a joke! The Jidenco/Falcon kit is not only dreadful but it is also about as common as rocking horse poo so it to is making ridiculous money at auction. My only real hope was picking one up at a bring and buy stall at an exhibition but the effing plague put an end to that happening. Oh well never mind. Keep up the good work mate. Regards Lez.
  12. Nice Al, very, Very Nice! Regards Lez.
  13. It looks fab Al. Well worth the effort mate. Regards Lez.
  14. Nice mate. Regards Lez.
  15. Yeh it looks nice Bob. However you will need to think about the locking room entrance for the rods and wires it ain't doing no good where it is up in the air, it needs to be at track level. Regards Lez.
