      I can work on these next. Should be ready in a week or so (time permitting). I will send out an email to all members when they are ready.

    Really impressed with your construction of the dunk tank. Looking to build something similar on a missions trip in Nicaragua. Would love to get a hold of these as soon as they are available. Thank you

    Been studying and collecting parts for awhile. Can use all the help i can get. Your design is awesome! Help. Truth is can’t afford materials to finish my home! Family is living on a job sit. Have land with alot of lumber to select from. Your saw mill is the best logical option I have.

      I will do my best to release a set within the next day or 2. Even if it is missing a few details, I will release anyway and if you have questions I will answer and update the plans as we go…

    I downloaded the sawmill plans today and everything looks great… except after page 32 they are blank. I tried downloading them a second time and the same thing?

    Thank you so much. Plans are great!
    Really looking forward to the blade guide chapter… wondering about pully size? What r.p.m. am i shooting for? Only have a 8hp motor. Will that be enough power? Would a higher r.p.m help it cut better? Would that heat up the blade? Water drip system to cool blade? Carriage is complete, attempting to mount the tensioner, and wheel bearings after work today. It is a very nice thing you have done releasing these plans to the public. Thank you again!

      I will be covering pulley sizing in the plans, but until I get them ready you can use this info. You are aiming for 4500-5000 SFPM (surface Feet Per Minute) of the Blade. Your engine will be rotating at around 3200 rpm . Use the calculator on this page http://vintagemachinery.org/math/sfpm.aspx to calculate your pulley diameters. one example that works would be: engine pulley dia = 3″ Drive pulley = 12″ Bandwheel / dummy tire Dia = 24″ final SFPM of blade = 5,000 you will need to measure your tires dia and then play with the calculator from there. There are many combinations that will work. One limiting factor may be what dia pulley you can source for your drive pulley as it is the larger one.

    Thinking 6-7000 sfpm would cut faster. The only real downfall i can see, with a higher speed, is heat….. water cooling the blade could fix that. What would be the downfall of a higher sfpm? I only have a 8hp engin..guess im trying to compensate in some way for that.. thoughts? Strait, fast, and accurate is my goal..thank you.

      It wouldn’t hurt to give it a try… If it doesn’t cut the way you expected you can always change out a pulley to adjust the speed. Let us know how you make out.

    How long untill the blade guide, a drive axel/drive pully chapters are complete? Super eager to study them! These plans are awesome! My teenage boys are really starting to get into the build too!

      I am just about done, but have had other things on the go the past couple days. The last part I have to detail is the bunks for the logs to sit on and the clamping system for the logs. I will release by Monday with or without the bunks, and clamping.

    For your upright posts you used 3 1/2″ tube. I have access to 2 1/2″ for free… do you think it will be heavy enough?

      Hi Marc, I think it will be strong enough, but I would definitely add gussets to strengthen the attachment points on the feet and top cross brace. Especially at the feet as there is a lot of stress at this point.

      Sorry, I’ve been on vacation and have had limited access to Wi-Fi. I do see your email, and your build looks great so far! I am impressed with your creativity to work with what you have found for materials. I will reply to your email with more details when I get back home.

    I have heard that a 1″ drive shaft is not heavy enough… what is your experience on this?

    • jrush331

      August 18, 2016 #30 Author

      I would not be concerned at all with a 1″ drive shaft for this application. The main thing would be that it is supported properly. I would make sure to add the outboard support bearing/block as outlined in the plans.

    Could you leave the CV joint on the axle and cut the opposite end (transmission end) to add a pulley? This would be easier than welding a shaft perfectly straight.

      August 23, 2016 #32 Author

      you could do that, but you would need to add an extra support bearing so that the shaft would be held from flopping around…. This would mean you would have 2 pillow blocks. 1 right after the CV joint and 1 as in the plans already right before the pulley.

    I tried that at first on my build. Smallest shaft I had was still too long for any design simulator. Would make the whole thing out of balance. Sure it would work out fine though, if you changed a few things. If you use it that way, please post pics. Would be awesome to see how you made it work? Hard to imagine any kind of support for the axle, that would stand the test of time, like the bearing block. Wouldn’t be able to use one, if you went with the full shaft. Unless there is some kind of spilt ring kind of bearing out there….
