Well done Kirk, that's turned out well. I look forward to seeing what it looks like when polished up :thumbup: Tim |

I've been wondering what a "paddle duck engine" was ever since I first wandered across the reference, and I have to say, having seen it, you are making a serious job out of it, and your's is looking great. Your tubing bender picture is an improvement on the one I was going to make for the tubing for my radial engine, so I think I'll use your design and get better results. I was once a certified micro miniature electronics repairman, while serving in the Marine Corps, and was taught the secret to soldering is 95% cleaning, and the remainder careful workmanship. When soldering for strength as opposed to electrical work, tinning the whole site which you want solder sticking to, is the best preparation, both the bar, with its hole tinned, and the ends of the tubing. Once this is done, you will never have an inclusion or break in the soldering job. Chalk can be used to limit where the solder runs to, including the sticks sold for marking out steel or rusty metal. This works with pretty much any kind of solder including "hard" silver solder as well as soft. That's a great looking engine, I can't wait to see and hear it run!! :ddb: mad jack |
