Danny, I am looking forward to this. I may not be able to participate but will cheer the teams on.


Thanks Stan! It is amazing how pronounced the difference in sound is in person but not at all in the vids.


This really is getting fun. Some really out of the box stuff.

Or, just send it to me. I will start it about 3 AM. Within 2 minutes I will be able to tell you what time it is, what's wrong with me, where I can stuff the bike, and how loud it is. :giggle:

LOL Denny! I bet.

I had actually thought or wondered what you would come up with based on some of your works. Wood sprockets/ gear box? (sitting here thinking about that, would be self lubricating if oil or grease soaked and could put metal on the contact points,,,,hmmm)

One of the most amazing MB concepts I have seen is a builder named "Fishguts" His entry is a steam powered Happy Time! The boiler is mounted aft and is uber cool looking. The thing is just incredible! Really looks like some thing from 1870. :eek:

Well, don't have anything too outlandish in mind I guess. Am thinking about a kinda sorta recumbent thing. Mostly want to try that because it looks easier to put some kind of fairing ala rain protection on it. That one is still in the thinking-part scrounging stage.

I did build a kinda sorta stretch with a Titan and home brew drive train that has been very dependable. Right now I am trying to come up with a charging system to keep the lights brighter (dark all the time here) and of course for the heated cup holder to keep my coffee hot. So far I have tried PM motors, scooter motors, a belt driven alternator, and a few other things. Didn't like any of them for one reason or another. My latest thing is peltier modules. Thinking, why not use heat that is being wasted anyways to generate the electricity. Also it should be lighter.......and no moving parts to wear out. Spose I could build an enclosed recumbent using an engine that just warms up a Peltier module to charge the batteries to run a couple hubmotors.

Would electric longjohns qualify for the contest?
 
Stopped by PC just to do a quick email check. Read your post in a bit of a rush and ya'd never guess where I thought you were going with "cup warmer"

Insert Alaska is cold joke here, snork

Always thought exhaust heat was waisted. Even a passive heat exchanger sort of thing... dunno.

Speaking of exhaustion, finally got the Thump-Thump muffler sound I was going for! The rubber works as sort of boost bottle and thumps the vibration back threw the real muffler! Is very cool sounding. At least in the shop/garage with the doors closed. Gives it an almost brutish, old world engine sound over the tinny well muffled sound.

(Edit; Had blow bag switch off so the "cool thump-thump" sound was real muffler alone. me slow) Still sounds cool and going to test at WOT)

"Would electric longjohns qualify for the contest?" Not sure, but exhaust warmed long-johns sure would, lol
