Hi all
I'm curious about the walking beam design.
I'm currently gathering my parts for a huge model built from
a 55 gallon drum and perhaps 4 inch piston, then later perhaps out of a larger huger drum. This should be fun.
My flywheel and linkage will be a standard bicycle, but must be hard linked not freewheel type like a 10 speed is.The one speed type bike will be best that can peddle in both directions;and not like a ten speed which peddles in one direction only.
Anyhow my question is about the displacer:
What portion / % of the displacer requires the heat and the cooling ?
Is it better to just heat only the bottom of the displacer ? or should the heat be the bottom half or bottom 1/4 of the entire drum?
Same question for the coolant portion ?
Should the upper whole half be cooled ? or should only the top 1/4 or only the very top be cooled ?
Which is best
Please advise
Thanks
