Chris,Sounds like you had a fun day at the lake. The Seaview and the flying saucer are a blast from the past. By the way I have some old RC airplane stuff that is 72Mhz let me know if you know someone interested. I got it at a garage sale and intended to use it in a boat. I think it has been sitting around 5 years & could use a good home. PM me if you know someone interested.Art
Chris,Was just a thought, so... what would have happened had I inappropriately used it for a boat?Art
What, no Frequency Enforcement Swat Team, with Crystal Gale leading it? I guess the big thump could happen if the RC plane user was within a kilometre or two of the boat RC user, the range of RC transmitter would not likely be much more than that, would it Chris? (you know a LOT more about RC than I do, but that's a sub-topic.... sorry bad pun without pun alert)
Crueby:It's a little late now that you've already got the supplies you need for chemical etching, but did you think about electro-etching using salt water, something like this? https://www.youtube.com/watch?v=IAvdEGZTSdQI've seen it used on steel and stainless steel before, both for etching a pattern as you did and also for through etching pulse-jet reed valves out of sheet stainless. I wasn't sure if it would work with non-ferrous metals but from the Google hits that I got when searching electro-etching copper - apparently it does. No nasty chemicals required, just salt water and a little low voltage angry pixie wrangling.Don

I have extra pieces of the design on the transfer paper sheet, going to give it a try - already have a salt, distilled water, container, power supply, so should be good to go. Will report back later!Chris
ChrisNot to be a wet blanket but take care When I was at the iron works they had a chemical they used salt cells to produce chlorine gas , this was then burnt in a hydrogen flame the vapours were condensed into hydrochloric acidThat said please google passing a electric current though a salt solution You would have been fascinated with the gas engines ( waste gas from the blast furnaces ) to stand at the valve end with a 9 foot stroke I will try to find some pics
