Questions
- What is the rationale for a circular saw instead of a bandsaw?
- Both have strength and weaknesses. Circular saws are simpler to drive - they can be connected directly to a hydraulic motor though a belt might be required to increase the speed. Circular saws are repairable (see below) and easier to fabricate. OTOH, bandsaws have a deeper cut which means that bigger logs can be processed. Most commercial portable saw mills are based on a bandsaw.
- Can new teeth be attached to a regular circular saw blade through brazing?
- Yes, but it is a technique that requires some skill. They can also be welded back in place. You need a fine point welder to do this and care must be taken to avoid warping the blade. Blacksmiths used to forge-weld teeth onto broken circular saw blades.
- How should the saws be attached to the vertical posts?
- Maybe with square tubing.
- How sturdy do the saw assembly, posts, and cage need to be?
- The saws should be about 80 lbs, and with the posts and cage about 255 total.
- What forces are going to be acting upon the frame?
- Try doing a Finite Element Analysis test.
- What is the industry standard for rollers/bearings on sawmills? How should the bearings be made?
