Hi Chris,
Thats interesting and outrageous that it would cost so much to do something permanent for a head frame. Sounds like a smart idea with the portable headframe and I think it will fit it quite nicely wth your current display. Quite fitting for getting the beginnings of a prospector shaft. Make sure to post an update when you have it completed! The Mancha is a great little machine and thank you for the lin drawing. It gives ideas and ill look deeper into seeing if there are any drawings of it around.
Best,
Ethan
We have witnessed valley
and plain and crest,
Canon and pass we've scanned;
We have seen the best
of the glorious West,
by the trail of the Rio Grande
