Re: Info on nitinol wire loop?

Thanks, Pete. I'll check into the crimp connectors. I wasn't sure you could treat nitinol like regular copper wire - titanium being such a peculiar metal, & since the wire will be constantly flexing around 2 pulley wheels. Someone else suggested heat shrink tubing - which might give the splice sligh...

Re: ADVICE on unsealed alcohol lamp?

I think you must be right. I had not considered the vapor venting thru the wick. I also live in a small town (pop about 2300) in southern Florida. But that's about where the similarities end. It's mostly hot & sticky 9 months out of the year. This locale is as flat as yours is mountainous & the clos...

Re: Info on nitinol wire loop?

Sorry, cbstirling2. I'm really lousy w/computers. Don't know how to do the "cut & paste" thing. Hey - try this one: "www.google.com/search?q=nitinol+engine&rlz" & take your pick. Or type in "heatmobile" or "thermobile" or "nitinol wire engine" into your search engine, then select "images" or "videos...

Info on nitinol wire loop?

Anyone have any info/advice on easiest way to connect ends of a straight nitinol wire - w/o welding - to form a loop? I want to make a simple nitinol heat engine similar to the heatmobile/thermomobile designs I see on Amazon/u-tube/ebay. Being a tightwad by nature - I don't want to pay the ridiculou...

Re: ADVICE on unsealed alcohol lamp?

I have located a metal spirit lamp(I think it's made of some lower grade of stainless steel or tin - it's not magnetic) short enough for my purposes, but it also has an aluminum wick holder - which is pressed/sealed into the lid of the lamp. I have ordered a fiberglass wick to use w/this lamp, since...

Re: ADVICE on unsealed alcohol lamp?

Thanks Ian S C - I will check into finding a ceramic lamp cap/wick holder - sounds like a good idea. My cap is metal (maybe "pot metal" or aluminum?),so I'm not sure a different metal cap will solve my problem. Using a metal wick also sounds like a possible solution. I could switch to a metal lamp w...

ADVICE on unsealed alcohol lamp?

SETUP: I have a stirling engine bolted onto a metal plate. I use a 33 mm tall, 5 ml glass alcohol lamp heat source because it's the only one I have small enough to fit in the space beneath the power piston. I don't like candles because of the sooty residue. I prefer a glass lamp because I can see th...
