Engel U177 Type IX D2 Contruction question

Postby P Webster » Mon Dec 31, 2012 8:08 pm

I am up to the stage of installing the electronic internals of the sub and I see that Engel say to remove all electronic components prior to gluing the middle deck (AKA, the wtc cover) in position.
Can someone explain why this is required.

Some adhesives can destroy electronic components.
Kind regards,
Giovanni

Giovanni,
Thanks for your quick reply. I thought this may have been the case but the adhesive I am using is "Great Planes" 90min epoxy resin and have been using this for years on my aircraft and train models with no effects on any circuits.
Maybe I've been lucky but I will heed your advice and not re-install any gear for 24 hours ( stated curing time), after application, as this will be a fairly heavy application around the middle deck.
Once again thanks

Is that what Engel recommend you use.

I haven't got that kit, but I'm pretty sure it's a polyester hull, and if so ideally you should bond the two halves together with polyester resin and some cloth reinforcement.

The two types of glues I have are Great Planes , as previously mentioned, and "Bob Smith Industries" glue, both 30min. to 90min. setting time.
I am mainly wanting to use these to glue support plates for things such as the radio gear, lead ballast, dive tubes and allied switch circuits. I have looked on both bottles and there is no mention of what type of glue it is. I guess you learn as you go along.
Can any Aussie members assist in telling me where I can get some polyester adhesive. I will buy it from overseas if need be.
Sorry to be a pest but I just want to get it right

Being the Uk I can't recommend any supply places down under, but a quick google brought up a number of options. This site looked quite good, and do everything you need-

You will only need a small quantity of resin 0.5 litre should be more than adequate.

Here in Oz yacht chandlers invariably carry a good range of polyester materials, good quality epoxy. For bonding acrylic, I go to a local sign fabricator who will sell you a tin of what you need.....

Me again guys,
After having another a more thorough read of the building instruction book I see that Engel mention that you can use either epoxy or polyester resins on all but the installation of the middle deck i.e. the water tight section.
To glue this they state that this "should be glued in with the Polyester Laminating Resin" and advising that it should be thickened using micro-balloons.
I have found this laminating resin at our local Paint Stop store, so it looks like this problem is solved but no doubt there will be many more to come so I will just have to, as my Dad use to say, make haste slowly.
Thanks for everyone's help.
