Great job, Mike! I can't wait to see this progress and am glad to see you back at the bench. I guess we are all SOL in 7-weeks when you girlfriend returns from Italy (unless she finds some Italian Stallion over there: whoa better not let your mind start thinking about that...forget what I just said, LOL).
I think you are right on the money with the soldering tips. I've found that what works for me is to get the basic frame together. Then start soldering and adding bits and pieces as you progress and try working to where the joints farthest away from each other are done first. That way when you solder parts that are closer together, you have a structure around it so that the joints may heat and cool and not really move.
Others have discussed using varying melting point solders using the highest melting solder to do the first items and then work your way down to the lower melting point solder. I haven't personally tried this approach, but since these are some accomplished folkds, I assume this approach does work.
Another approach is to use heatsinks. You would obviously have to be careful as heat sinks will draw heat from the part and if it draws it away from the area you need to get to too much, it could pose some problems.
Finally, from time-to-time, I use a product that I purchased from Small Pats, Inc., called "Heat Shielding Compound". It is a paste that you can mold somewhat like clay. As the heat gets to it, I don't think it as much dissipates the heat as much I noticed it hardens and believe that it holds the parts in place such that when the solder loosens, it holds the two parts in place. Again, I don't know how the technology of this product works, but do know that it has helped me in many applications. Anyone interested can look it up on their website, but when I went to copy the link, I noticed they are out of stock. I need to do a search on-line to see if anyone else carries this or a similar product (should have stocked up when I had a chance) http://www.smallparts.com/s?searchNodeID=1...p;Action=submit
