Thank you for sharing the process. I've loved following your growth as well. I don't want to seem intrusive. Just take note.
One of the easiest ways of prototyping is 3d printing. You can find lots of free sources for downloading. If you have free time you can easily learn how to model easy things yourself. The FreeCad program can be useful for beginners.

Hi folks,
while having some tough times, I recently got myself back to the donkey project. Not much, but one step further... Hopefuly I'll stick to it during the next weeks as times and moods allow.

Re: An homemade steam donkey
Two days ago I had the chance to see Gerd's steam donkey in real life.
It looks perfect and runs like a clockwork!
I'm looking forward to see it in steam
Cheers
Tom

Re: An homemade steam donkey
Very nice! I'm not a donkey expert, but it looks exactly like I would expect one to look.

Re: An homemade steam donkey
Thanks for the feedback
My steam donkey is a freelanced hybrid, combining the Dolbeer design for boiler and engine with typical two drum arrangement of a wide fase donkey.
Such two drum donkey usualy had two cylinder engines, which were mounted left and right to the boiler along the frame, just as represented by the Harris-Donkey.
Never the less, my steam donkey conbines parts and designs used by Orr & Sembower, so it can be described as plausible engine, maybe created from existing components, of build on sepcial order.
Anyhow, I can't wait to learn how to operate such an engine in logging duties. Reading books about the topic is onw thing, but trying yourself on crotch-line-loading or highlead yarding systems will become very interesting.
I look forward to get some timbers tomorrow, to start with the sled.

Cool!
The next level of difficulty is to move the donkey under its own power across a river while suspended by a cable strung over a river.
