Here's a video of the second log I've cut up. I had to do a little adjustment at the beginning, and now it's working beyond my expectations. A little bit more practice and I'll be running it a lot more efficiently.
Very nice, consistent cutting. I've always been skeptical about using tires for bandwheels, but you've shown how well it works. I kept waiting for you to cut into the clamp. Guess I'll have to wait a little longer.
I wasn't sure if using those big 27'' tires would work. Those wheels are 50 pounds each. I figure the weight of those heavy wheels would give inertia for cutting,which I believe it has.The video shows the blade cutting the wood like hot knife through butter. Also what I like about using tires is I don't need to have water running on the blade to cut.
Went up into the woods Sunday and cut down a popular along the side of the road that was in the way, and not a very good tree. Here is a video of one of the logs from that tree on the mill. It was about 36'' wide at the widest part of the log.
The only thing that jumps out to me, and Im not sure Im seeng clearly in the video, is it looks like your bunks may be very light and I would fear over time they are just not going to hold up. But again, may be seeing incorrectly in the video.
In my experience rolling logs on a mill over time is absolutely brutal. Members twice as robust as you would normally think will be bent and distorted in just a short time of sawing.
Nice though all in all. Likely a very rewarding project.
The task at hand now is working on the "sawyer" part. Learning to read your logs, cut tension out of a log, and get the best possible boards you can out of each log because home built mill or not, if you apply $5/hour to your time, these will be some of the most expensive boards you will ever lay your hands on. So better make sure they are as nice as possible.
When you see board springing off the cant as your sawing them you know they are going to get worse each minute that passes.
I go along with beefing up the cross members, maybe using square tubing. The main thing I see is that the cut appears to be smooth and straight. You sawed it exactly the way I would have, which is the curve flat on the track, and leaving both edges natural. I looks like that piece might have been from a branch-- or from a very crooked tree. Either way, it would have a lot of stress. When you get cutting straight logs, you'll be amazed at how much more satisfied you'll be with the mill. Those slabs have good potential for a counter top, bench, or table.
I agree the cross members are a little weak,but they were what was laying around so I used them. I'll more then likely replace them with something stronger. Someone wanted to see a better video of how I built the bandsaw mill,so I hope this video helps. If not I'll make another one on what I didn't explain in this one very well.

WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.

Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.

Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
