John Morris Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) That sure is weird isn't it James? Seems like the opposite would happen, if it is crowned it would ride down and off the wheel. If it was concave it would stay in the center, but as Larry says, the blade tracks to the center of the wheel with a crown. Crown is better.

Larry Buskirk Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) James, It helps to keep the blade centered on the tire. Tracking still has to be adjusted. The blade tends to climb the angle of the crown due to the centrifugal force of the wheel spinning.

John Morris Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Larry, your a genius man. For those that don't know it, don't let the beard and easy going attitude that Larry has fool you. He helped me rewire a drill press motor over the chat feature here on TPW, and it was successful!

James Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Yeah, you said it John. That sure is weird. It made me think again and again. Good thing Larry is here to help me. Thanks again Larry! www.bandsawblog.com Edited November 12, 2018 by Larry Buskirk Quote Link to comment Share on other sites More sharing options...
Charles Nicholls Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) I need to figure out why I keep breaking blades. usually about once a month I will break a blade and I'm not sure if it's because the blade is placed wrong or if its too tight or whatever. It can't be too loose or it would just fall off or not cut well. the blade usually comes to rest on the forward edge of the tire. That seems to be where it just likes to be. I'm still using the old 3 wheel Craftsman saw that Ron sent me a year or so ago. http://www.etsy.com/shop/nichollswoodworks Edited November 12, 2018 by Larry Buskirk Quote Link to comment Share on other sites More sharing options...
Ron Dudelston Posted September 14, 2012 Author Report Share Posted September 14, 2012 (edited) I always have to bow in humility at Larry's machine knowledge. Edited November 12, 2018 by Larry Buskirk Quote Link to comment Share on other sites More sharing options...
Larry Buskirk Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Charles, Do you have a model number for the saw? I'll try looking up the manual to see if I might be able to help figure out why it tracks to the forward edge of the tire.

James Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Charles, My online supplier for band saw blades told me that there are at least 22 variables that influence a band saw blade life: (Below apply to working with woods, metals, plastics etc.) 1. The Operators, The operator knows the machine best. 2. The number of teeth in the band should have 3 minimum, 6-12 optimum, 24 maximum. 3. Tooth style, Choose the tooth style that best meets your cutting requirements. 4. Tooth set, Regular, Wavy, Every Tooth Set, or Modified Raker 5. Band Tension, Proper tension should be applied. 6. Band Speed, Start with the manufacturer's recommendation. 7. Break-In procedure, Reduce normal feed rate by 1/2 for every new blade. 8. Feed Rate, Set rate by square inches per minute suggested by manufacturer. 9. Band Quality, Carbon vs Bimetal or Carbide Tipped, one brand vs. another. 10. Machine Type, Different makes and models, hp of motor 11. Wheels, Check alignment, bearings, flanges. 12. Machine condition, Old, new, well-maintained. 13. Proper Vises, To hold the work firmly. 14. Guides, Should support the band, roller guides should barely turn by hand 15. Guide Arms, Should be as close to the work as possible for support. 16. Brushes, Aid in the cleaning of chips from the gullet of the band. 17.Production Requirements, Continuous vs. Intermittent Use. ( Below apply to working with metals) 18. Coolant, Should wash, cool and lubricate. 19. Material Machinability, The toughness of a metal can reduce tool life. 20. Material Hardness, Rc of 40 has a machinability approaching 0 21. Material Shape, Structural and small solids tend to be harder on the band. 22. Room temperature, Affects hydraulic fluids in the machine. Hope this helps! www.bandsawblog.com Edited November 12, 2018 by Larry Buskirk Quote Link to comment Share on other sites More sharing options...
John Morris Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Charles, Can you snap a pic of your saw and post it here, or better yet start a new discussion about your bandsaw issues, I'd like to delve into this deeper and address the issues.

James Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) I agree, John. And I also feel the same. Let's talk about it deeper in a thread addressed mainly for it. www.bandsawblog.com Edited November 12, 2018 by Larry Buskirk Quote Link to comment Share on other sites More sharing options...

Charles Nicholls Posted September 14, 2012 Report Share Posted September 14, 2012 (edited) Ok guys, here is that discussion which includes blade size, tooth configuration, as well as model number.
