Help - Reinforcing and Detailing my scratchbuild

Post by Munty »

Hi guys, I've been away a long time (as always) but a friend of mine is now encouraging me to return to my tank building project before I take on another one! He's right, but as always there's a reason I stopped in the first place... I now have a plasticard body in it's final shape and form, all 4 gearboxes mounted, one sprocket/axle thingy finished and 2 of the 4 tracks built.

Trouble is, there's not a great deal of this stuff that I would deem 'acceptable' in final terms and I can't really think of how to recitify this myself. So I thought I would come here and ask some of you fine people in the hope that someone can direct me in the right direction and get this build back on track!

Following are a few pics of what I have so far for those who aren't familiar with the project. Remember this is a fantasy vehicle from a computer game so it may all look rather odd to most of you! That said, it's a 1990's soviet design so the building techniques and such are absolutely terrestrial...

First up, my biggest concern is strengthening and smoothing the hull. It will remain highly angular so nothing needs to BE smooth per se but all of the visible joins need filling and reinforcing at the same time. The turret is already pretty solid so can forego extra work for now but will still need the edges filling... The biggest structural issue is going to be the internal joints in the hull which, although quite firm already, will see a lot of action eventually! I'm thinking some kind of glass fibre tape or something could work here but really need advice from people who know better than me so send it in please!

The other problem which is less structural but still very important is the track armour which plays a part in holding the drive sprockets, bogey wheels and probably suspension too. It has far fewer pieces than the rest of the build but fewer angles in this case tend to make it much weaker, especially the very long side pieces... My first job now I'm back on the build is to reinforce the joins between the hull and track housings which I already have a series of small bolts for. Currently they're glued as best I can but without much more than that I'd be asking for trouble. But what about all the other joins that are so vulnerable? I really want a great deal more strength in these pieces but just don't know how best to do it...

The other issue before I can detail anything (the whole thing will have armour plating added later which should make a BIG difference as the surfaces are huge right now) is the filling of all the external joins. As I said, they don't need smoothing, just filling, but I'm not sure what product to use. I build with 3mm plasticard so was thinking just normal model filler may work but I'd guess I have many many meters of filling ahead of me and I'm wondering if there may be a better, stronger, more enduring way of doing it...

Anyone who can advise me on these issues please do as there's not too much I can do without this vital reinforcement. As a final note, I still need someone to help me out by making some barrels for this build. Anyone interested should give me a shout!

Munty,

Is this the tank from Command and Conquer series of PC games ? I think I actually have a 1/72 scale or there about plastic model of it. I will have to look but would that help you out as well ?

Hi I build with plastacard as well I have found that for filling halfords do a plastic bumper repair filler that flex's and adhere's well It depends on the amount of filling you have, but for me fillings small gaps in seams and also if left to dry it can be worked into small fittings. It has not caused me any problems and works well.

Hi Michael, it is indeed! Is this the model you have?

Found the image on google back in the early days of the build and I'm pretty sure it's based off the C&C : Renegade version of the tank which is where I got the dimensions and details for my own. I've only ever seen the one good image of this model, I think they're pretty hard to come by, so would love to see more if you come across yours at some point! The build thread for my Mk.1 Mammoth is here on the site if you're interested! http://www.rctankwarfare.co.uk/forums/v ... =23&t=7270

Denzil, that sounds pretty promising! Got a Halfords not too far from here too so may swing by and see what they have. I imagine this would only be suitable for my filling issue and not so much for additional strength would it? I'm really hoping someone can tell me about fibre tape, there are some good videos that show it being used to repair RC car bodies and such but not sure if it would be suitable in this case...

Thanks for the quick replies folks, please keep them coming! T

Hi I have used Fastglass fibreglass repair kit on plastic before, it gives good strenght but if the item flexes it some looses adhesion and pops off. As an idea try the plastic bumper repair filler and tease some fibre glass strands into it, this may give you the best of two worlds ie . good adhesion to plastic and the strands some strenght. When I built my 7ft submarine the hull use to flex on that and I screwed tiny screws (m1.5 X 5mm ) into the hull near the bulkheads and then fibre glassed over them, this gave me strenght and the protuding screw heads gave me a good achor
hopes this helps.

Sub sounds cool! Thanks for more tips, that's the sort of product I'm thinking may work here but I guess still no closer to finding a perfect solution with those limitations... To be fair though, I don't WANT the body to flex when it's finished so maybe it would be ok?

Anyone come across the repair tape you can get for cricket bats and hockey sticks and such? Even fishing rods have products for them I think and none of them require any third party solution to complete the repair. Is there something like this that could work???
