I really wanna build a homemade mill from the junk scrap at the scrapyard next door. I've been asking myself this question a lot thank you for this video!
Great video. Am building a home made Bandsaw Mill after half a lifetime of using Circle and Swingblade mills. This is invaluble information. Thanks so much.
Thanks! I've watched all the videos in this series so far and this one is the best yet. Very informative and dispels a few incorrect assumptions that I had (and probably other sawyers have).
that really makes sense and I now see why the build up on the blade it needs to get bigger dust by either pushing a bit faster or a combo of sharper and faster cutting
So you speak of travel speed at 8ft per min, this would obviously depend on log diameter. I have a custom-built sawmill and I am running at 4500 ft per min 1.5in blade and log diameter ranging from 30in - 55in so what kind of travel speed should I be looking for? I have followed your videos and set up the guides and wheel as you teach but still get a lot of climb and dive. Do I need to go to a wider blade? Thanks for all the great videos, I am learning a lot from you!
This is a very interesting video, but I am left scratching my head as to how one would actually measure/verify speed. Perhaps it's because I have a Fisher-Price sawmill (Harbor Freight), but I'm clueless how I would determine even RPM, let alone FPM.
There’s probably more than one way to figure it out but here is one: Multiply your band wheel diameter by pi then divide that sum by 12 and that will give you the feet per revolution. Example: 26” x 3.14(pi) = 81 ÷ 12 = 6.80 ft. per revolution Next you’ll need to figure your pulley ratios by taking the diameter of your blade drive pulley (the pulley that powers your blade band wheel or drive wheel) and divide it by your engine pulley. Example: 16” ÷ 3.83” = 4.17 ratio. Next take your engine rpm and divide it by the pulley ratio you got in order to get the rpm at the drive pulley. Example: 3400rpm ÷ 4.17 = 815 rpm (this will be what your drive band wheel is turning) Lastly, multiply the drive wheel pulley rpm by the revolutions per ft. Example: 6.80 x 815 = 5,542 ft per minute. Hope that helps.
HA! I am so glad people like you paid attention in math class! If it was up to me, we'd still be in the stone age :) I was hoping more for an answer like: "Buy THIS widget and it will tell you". Short of that, I think I'll just have to be happy not knowing.
I'm assuming he could have just told the rpm speed he used to achieve the feet per minute speed with those sizes, which is what 90% of people are looking for. But hey, he hit that magic 10 minute mark. I'm just starting my build but here's my pledge.. as soon as I find the rpm to wheel ratio that results in the correct bfpm, I'm going to leave the calculation in every comment section of these kinds of videos.

Tighten your blade more

lol, if we can help you figure anything out shoot us an email at sales@cookssaw.com
take care

@@josephclark6695 still waiting for those calculations mate
5280 ft/min is 60 mph
