What ARE you waffling on about Eric?? There are only small amounts of Araldite involved and I detect hardly any smell at all. Are you sure you haven't got your head to close to your arse again??

Yahoo, Whoopee, clap hands, dancing on the ceiling - I found it!!! The magic temperature is 185 C. I heated the thing up in the oven for an hour and pulled it out - the epoxy had turned into some sort of semi liquid goo about the consistency of thick honey - carefully pulled back at each corner of the frames and they slid along the brass tubes - got two off before the temp dropped and the goo solidified - not the usual colour of epoxy - sort of a burnt honey brown colour. It held the joins although I would not want to use it like that - AFTER it's been heated - in a high stress joint.

So now I know how to undo metal to metal joins that have been epoxied. Note that I did not use the term Araldite because I don't know what brand/ formula is in use. Eric suggests that Araldite stinks when heated/burnt and this stuff has no discernable odour so this might not be that brand but it's working for me. Next step - back in the oven and hopefully get the other frames off as well.

Well done Mick, perseverence seems to pay off

Thinking about it heating is the recommended way of softening epoxy. Its called the T_g point. It is lowest for room temperature cured epoxies and can be as low as 75 degrees C.

Awwwww Klippy - I didn't call you a liar mate - I just suggested that if you were a marksman you couldn't hit the side of a barn at point blank range with a bloody bulldozer.

Well - I've finally got the damn think apart. Now all I have to do is clean it thoroughly, build a jig so I can get it all aligned properly and go from there. At the current rate of progress, and bearing in mind that I have to make several parts that are missing - which means not only making a mould but working out what the missing part is from photos and then trying to duplicate it!! I think this model will be finished about the time hell freezes over - or - perhaps - with a little luck - slightly before!!!


When it's all disassembled it doesn't look like much does it??

If your going to put it together why did you make such a fuss and pull it apart are you a perfectionist or what,and an electric motor as well,softy

I pulled it apart Stephen because the person who part built it made a bloody mess of the construction, he got about half way through and gave up. The bits sat in a box for I don't know how long - but as usually happens parts went missing, were lost or broken. I bought it very cheaply to see if I could meet the challenge of restoring it. IF I install an electric motor it will only be to turn the prop/engine for demo purposes - This is NOT a flying model.

Its an interesting diversion.A lot of my clubs elder members build models that can fly but they never fly anything.When we go to the Blackbushe show,they arrive with ther beautiful models in pristine condition and hog the front of our display and us that do fly see models everywher that have never seen our flying site,.

Interesting comment Stephen but I don't know I would classify it as a diversion but rather a separate branch of the hobby where scale accuracy and detail is the primary aim. To build a flying scale model requires diversions from scale that disqualify the model from actually every being a scale miniature replica of the full size aircraft although many scale modelers come close with the outside appearance. Conversely if you want to replicate the full scale details and even materials of the original it is highly unlikely the model will be capable of radio controlled flight.

Yes there normally to heavy arent they.
