want to build a personal mill this summer. have decided to use rubber tire wheels and two post style with a winch to raise and lower the head. my question is - do you personally know of catastrophic or systemic failures of a particular feature or style that could be avoided by a design improvement. as an example i recently saw a picture posted of a sheared wheel shaft that i'm assuming was the result of undersizing the shaft.

most guys use rear car axles--with a bearing on them--but def get large enough ones--thats a LOT of sideload on that shaft--

2 post mill
Rubber tires, 2 post and a hand winch can be a very good design if properly construsted
What size logs and what horse power do you expect to use. I have many pictures in my coumpter if I can find them.

probably 10-30 inch spruce, balsam with some hardwood for flooring. at present I have a ten hp tecumsah that i plan to try at least until i get the bugs worked out. i do think that it should be sufficient. since the original post i have found a commercial rubber tire mill , TURNER, that lists its driveshaft as a 1.5 inch. i have also read on the forum site two opinions on cable lifts, one for and one against but no observational reasoning. opinions are interesting but i prefer case studies.

10 hp engine
A 10 hp Tecumseh engine is ok, Older brother and I have built and sold many mills with 10 hp engines, more hp. is better but 10 hp will work, before you spend any money take a look at my pictures, I will have one of my boys to find and send to you, I can and will give you all the information that you want just don't want to bore anyone unneeded information.

picture type
details are always good. do head slides need bearings? should guide bearings be pushing the band down slightly? will the head remain level with one central cable holding it?
i have more questions but that will get me started. i look forward to the pictures. thanks again.

band mill
the slides dont need bearings
use 2 cables
push guide bearings 1/2 to 5/8 in, keep in mind useing rubber tires, with low hp. and slow 4000 ft. band speed you use less band tension, band breaking is not a problem

Grampa, for us blokes still in the thinking/designing stage your pictures could just save us a whole heap of trouble farther down the track. I, for one, would love to see some pictures of your mills.
Cheers mate,
Dennis.

have also revisited a site called diy bandmill . sorry but i don't know how to do a link in this post. i had to slog through a lot of photos because the builds are for two post, four post, rubber tire, steel or cast big and small with some built from mostly scrap and some all new steel. different ones had brand new motors bought specifically for the job but others were like me and are using what they have or could come up with. one builder even had the complete base, motor and gearbox of a riding lawn tractor on his saw. double cool. well worth the visit and time to learn their way of storing photos.
still looking forward to the pictures from gene(grampa). he is the only person i have read about who has made more than one of these and i'm assuming for fun because from the work involved it would be hard to scrounge one and make money.

Alaskan Bandsaw mill pictures
This is a few pictures of Ooolder Brother and my 13 hp. mill that will cut a 24 in log 16 ft. long, the frame is 6 in. x 2 in. rectangular tubing 20 ft long.
We also build a 6.5 hp. mill that cuts 18 in. and a mill that will cut 30 in.
I have more pictures of different parts , that I need to sort out , that I will post later. I also have a 18 in. mill in the shop that will be finished in a few days that I can make pictures of that will be more organized.
