Well, today I bit the bullet and joined the deck to the hull on my Carbon Micro Magic and thanks to a couple of tips from the chaps here it went very well indeed, though I did use a different method of gluing most of the deck. I'm putting this in here just in case anyone else wants to try the method when it comes to doing this somewhat nasty job. It was my first time with ABS so I was a bit nervous about it.
...
I took a very slow route to do everything and it seems to have paid off, procedure was as follows, after I covered the aft end transom areas adjacent to where they are to be joined together, with masking tape to avoid glue marks on the boat.
1. ... Initially I glued in the rudder post to the bottom of the hull with UHU acrylit which makes it easy to locate the aft end when gluing. left that to set
2. ... Next using the UHU Acrylit I joined the hull and deck at the King Plank and top of the fin box only.... left that to set with rubber bands holding everything in place....
3. ... When that was dry I lifted up the aft end of the deck gently, put some UHU Acrylit around the rudder tube, where it is to join the deck, then put a fairly thick and slow cyanoacrylate glue just around the transom area and then positioned it all correctly and then held that area together till it had glued. The rest of this area being protected by the masking tape so no marks on the carbon effect. ... had a cuppa.....
4 . .. When dry .. went round the Deck/Hull join and at every couple of inches tacked them together using a fine brush and tiny amounts of EMA Plastic Weld at the join. put rubber bands around the lot and let it set again ... more tea..
5. ... Now that every thing was just about solid, it was a simple matter to just go round the whole hull/deck join with the small brush and EMA Plastic Weld, letting the capillary action complete the final weld around the whole of the hull.. replaced the elastic bands and had a large Malt Whisky.
Even taking into account the whisky, I now seem to have a completely joined hull and deck and without any nasty glue marks on the nice carbon effect, now that I've removed the masking tape. Thanks for all the advice chaps, working out this method took a bit of time but enabled me to take every step slowly, thus enabling a nice clean job. I know there are numerous ways to do it, as attested by some great boats out there, but this way worked for me.... I like slow......
