Hello fellow modellers, I have been dying to ask this question but haven't got many answers. I want to attempt a custom wideobody on a 1/24 scale car. It is virtually impossible to get tamiya 2 part epoxy putty in the uk from my experience. If you know anywhere that sells it please let me know. I have looked around and milliput seems to be coming up a lot. Which type of milliput would be the best for my purpose as there is the standard, turquoise, black, white etc. If not milliput what else could I use that would work well. I have heard about greenstuff but it seems to have mixed reviews.
Hello A new problem: I now need to connect styrene to a moderately waxy plastic (probably PE polyethylene or possibly PP polypropylene - I'm not 100% sure). All my experiments with plastic friendly epoxy glues & CA so far all say "won't work with PP or PE" ! One option would be to insert a couple of metal pins. But even then, aside of going for a good tight push fit, so far I cant find anything to actually bond to PE or PP. Any suggestions? Many thanks P.S. What about this: Starloc's "The 100% UNIVERSAL BONDING PACK" Which claims to bond: "TEFLON, PTFE, DELRIN, PVC, POLYETHYLENE, POLYPROPYLENE, SILICONE" http://www.shop4glue.com/universal-glue-bond-adhesive-repair-pack-metal-all-plastics-ptfe-polyethylene-polypropylene-silicone-81-p.asp The whole site looks extremely dodgy (!) and could well be a scam. But anyone here tried any of their stuff?
Hello I am building a model with an pretty strong spring in it, and I am extremely disappointed with Plastic Fusion ! (from Super Glue corp) On the upside, my Plasticard / HIPS styrene is mechanically stronger that I thought it would be an is fine. Bonding using EMA Plastic Weld cement is okay, but not brilliant. The problem I have is that any joint is nothing like as strong as the virgin material and thing can always be snapped off again at the original join. BUT after the rave review in this video by CustomsByZ ("Tutorial: The Basics of Working With Styrene" on YouTube)... I am extremely disappointed with Plastic Fusion from Super Glue corp! Even waiting a full 24 hour later the joint is just too weak. I have tried thee times now. - Yes I am mixing it up very thoroughly. - Yes I am doing so at a reasonable temperature (19deg) - Yes I am mixing it on card and using a the wooden spatula provided - Yes I am being careful and think I am getting the proportions about right - Yes I am working with clean (freshly filed) surfaces. However the resulting bond is little better than EMA Plastic Weld solvent - which is particularly irritating after all that time spent mixing the glue. Moreover and the setting time is also longer than expected. It says sets in "5-10 minutes" but that's a massive exaggeration, as in 10 minutes it's still pretty gooey and sticky. After 25 minutes it's pretty much a solid, although even after an hour I can still sink a fingernail into it. But either way it never, EVER gets as strong as solid the styrene itself! Not even close. Although I don't expect them to be as strong as an epoxy resin, I have now order some Tamiya Extra Thin cement and some Mr Cement S to see if either create something stronger than EMA Plastic Weld. Background I am layering up my 1mm Plasticard sheets using EMA Plastic Weld produce solids of 3-4mm and I am then joining those solids together at 90 degrees. To get clear, I am looking for joints of high mechanical strength, in order to resist the springs I am working with. The base styrene is strong enough for my purposes, although I had ordered up some ABS in case it wasn't. But I am now concerned that it's harder to glue ABS than styrene so that may prove to be a mistake. Of course what is so nice is that some sort of bond happens in c.10 seconds, but anyone know how long I should give the styrene to dry in order to achieve say 95% of maximum strength? Back to epoxies, I don't mind mixing up epoxy glues for say 30 seconds, even 1 minute (if I have to), but I do mind waiting for much longer than say 2 hours or so. Waiting for glues to dry is a serious problem for me as it interferes with the prototyping process itself. - What is the strongest glue for styrene that also sets fast - i.e. within 2 to 4 hours? Many thanks P.S. I am now wondering if maybe I have a bad batch of Plastic Fusion. What was worrying is that the very first thing to come out of one of the tubes was a transparent oily substance. So this may have been the problem with my first attempt. Fwiw, my attempts have all been using about pea-sized volumes of epoxy glue, and the epoxy looks what I assume is 'normal' (not streaked etc). I cant find any expiry date on the packaging... I got it off an eBay merchant "Motorway Hessle LTD" who have a good rating on eBay (99.8% after 71,162 feedbacks) :^( The Plastic Fusion glue I bought: http://www.ebay.co.uk/itm/Super-Glue-Epoxy-10-Minute-Plastic-Fusion-2-Part-Bond-Plastics-Glass-Rubber-/261508621516?
