bunchlox 16 Posted February 11, 2016 I'm trying to fill a hole in the bonnet of a FAV. I've done loads of repairs on Tamiya hard bodies before, but i now realise that the FAV bonnet is the same material as the chassis (which i think is ABS). Also, i think the driver figure is too, so i'll need some appropriate glue for that as well... Firstly, I'm trying to glue a plate to the back of the hole on the bonnet. I've sanded the back and the plate but the glues I've tried won't stick it. Maybe i'm expecting too strong a bond, but i don't want it falling off once I've painted it. I've tried Plasticweld (i realise that's more for styrene bodies etc), and I've just bought some Unibond ABS (and other plastics) epoxy glue and that's not held either. Ideally i'd like a glue/method of melting the two pieces together, so before i get me soldering iron out, are there any secrets i can be privvy to? Thanks for any help.

ChrisRx718 4470 Posted February 11, 2016 I've done similar on a Blackfoot body - is that ABS? Anyways, I used CA glue but an 'oversized' section of styrene plate to ensure I got good contact, since CA is very thin. I'm guessing you're covering up the hole where the mounted machine gun should be? Could you just put a nut and bolt in the hole and then proceed to fill it? It's quite a deep hole and it's got a shape to it as well, it may not even need a backing plate... Share this post Link to post Share on other sites

It's quite a deep hole and it's got a shape to it as well, it may not even need a backing plate... It did have a shape to the back but i've cut that off to get the plate to stick. Also, i tried your method first, but as the hole was too deep the filler just started to sink and melt the plastic anyway, so that's why i cut the back off. I'm now left with a 8mm diameter hole to fill, but it's now only the thickness of the bonnet. So, once i've found a glue suitable for the plate on the back, filling it will be easy... i hope.

Tamiyabigstuff 832 Posted February 11, 2016 I think waste pipe adhesive might be good for ABS ??? Try a plumbers merchant or a DIY store. Share this post Link to post Share on other sites
mastino 1085 Posted February 11, 2016 I've used TANGIT to fix ABS/ABS and ABS/forex (and, of course PVC/PVC) Share this post Link to post Share on other sites
Jeepy2013 575 Posted February 11, 2016 This is what I used, it works great, Testors 3502 liquid plastic cement, http://www.modeltrainstuff.com/Testors-Plastic-Cement-1-oz-p/rus-3502.htm I used it when building my 6x6 with a Bullhead cab, bonds styrene and ABS with no problem, kinda melts it together.

mr crispy 2293 Posted February 11, 2016 I had a similar problem gluing the rear window panel into a BF3 ABS body, I ended up using an epoxy glue called Super Steel I had from my motor bike days. http://www.ebay.co.uk/ulk/itm/291497582901 Mix equal amounts together and it ends up a useful dark metallic gun metal that sticks to virtually anything and doesn't shift once it's cures. I used it to fix a loose mirror on my courier bike, got knocked off the following day and even though the bike landed on the mirror it didn't move at all! Good stuff. That BF3 panel never did come out again 😜 I now use it for Tamiya chassis repairs. Share this post Link to post Share on other sites
shenlonco 1156 Posted February 12, 2016 Hi what plastruct did you use this one is way stronger than the white labeled bottle. also you ever use goop glue that stuff when dry holds most everything together! Sets in minutes Used for bonding Plastruct ABS, Styrene, Butyrate or Acrylic to each other, or in combination. http://www.ebay.com/itm/PLS00002-Plastiweld-ONE-BOTTLE-Aircraft-RC-Hobbies-/400889365177?hash=item5d56de42b9:g:F2kAAOSwrklVDdOe Share this post Link to post Share on other sites
stu22 12 Posted February 13, 2016 One of the tricks you use in bonding ABS parts that you make on a 3d printer is to melt some filament in acetone and use the paste as a glue. Essentially you are melting the two parts together but chemically instead of with heat. The paste also works pretty good to fill in gaps. To fill something like a body hole I tape some aluminum foil on the back side and fill it in with the stuff and wait for it to dry. Share this post Link to post Share on other sites
