Thanks Rick and Dan, your encouragement helps greatly.
Dan, I have a question. I have read of two methods for scoring a fold. First, very gently cut about 1/3 of the way through and fold with the cut on the outside if the bend. The other is to take a blunted blade such as a table knife or #11 blade that has been ground blunt and emboss a score line on what would be the inside of the fold. The first cuts the paper fibers that have to stretch longer around the outside of the curve, the other way actually stretches them without breaking the paper surface. Which do you prefer for glue tabs as opposed to straight folds across a part?
I think I found some of why my first assembly twisted. Has to do with using photo paper. White glue on a 90 degree joint will form a fillet sloping between the two pieces. The glue doesn't soak into the paper due to the coating, however it does shrink some while drying as is the way of white glue. This causes the fillet to pull the two pieces joined at a right angle to an angle less than 90 deg. On un-coated paper, the glue tends to soak in somewhat and not form much of a fillet, so there isn't much of a pull as the glue dries.
On my current build there are three bulkheads rising at right angles from the floor board. The middle has a slot in the floor matching a very thin bit of bulkhead fitting into the slot. That was easy enough to deal with by making sure there was a tiny fillet of glue on each side of the bulkhead. The pull from each fillet cancelled out and the bulkhead dried at right angles.
The bulkheads at each end of the floor board attach so that there can only be one fillet which will pull the front bulkhead back over the floor board and pull the rear bulkhead forward over the floor board. It is only a couple of degrees, but serves to mess up the fit of the skins as they are applied over the dried bulkheads and floor board. On the first attempt I kept adjusting the set of the front and rear bulkheads as they dried, but the glue still pulled them in. I'm not talking a large visible fillet of glue, rather what is left behind after wiping off the excess hardly visible, but since it is on coated paper, it doesn't soak in and so it exerts a pull. In the case of the front and rear bulkheads, I found a sparing application of CA was able to affix the bulkhead to the floor board at 90 deg and keep it there.
This may sound like a lot of fuss and bother to glue a couple bits of paper together, but it is just learning curve on the different properties of the media, both glues and papers. We have all learned not to use styrene glue on resin and we all keep CA well away from clear parts which haven't been coated in Future.
