That works great!! For the under side of where the screen is strips of wood screwed to the frame would support the wire mesh! This by far is the best design I have seen for DIY sifter! Simple inexpensive and does the job. I am adding a drive way and I need to use the dirt from the where the new drive way will be poured. The soil we have will be clumpy but with few rocks. Thanks for the feedback on the saw blade issue. I have some cold rolled flat stock that I will make as a blade substitute. The blades are brittle due to being heat treated. One thing you could do is anneal the blade prior to drilling the hole by heating blade to cherry red and letting it cool slowly. Don’t quench but keep the blade hot and move the flame father away from the blade over time. 😁🛫
The blades are only made for longitudinal stress But in your case the sifter can move left and right which puts bending forces on to the blade. They are hardened and tempered so they break. Restrict side movement of the sifter frame to the axle, natural to the sawblade. E.g. by adding gliding Aides in the left and right top side so the frame cant go there anymore.
Thanks for the video. I like that set up. I have been trying to figure out what to use as the agitator when I build my sifter and your idea is perfect.
You probably dont give a shit but if you guys are bored like me during the covid times you can watch pretty much all of the new movies on instaflixxer. Have been streaming with my gf recently =)
I made a similar sift of a reciprocating saw several years ago, but not suspended. Just had some 2x4 on top of saw horses on some pvc pipe rollers. Had it slanted so the larger material fell off one end. Cobbled it together from scraps to get through a pile of rocks trash and dirt. Got the job done but those blades kept breaking and the rollers kept sliding off, but it was just temporary.
Blades break. You are allowing them to take resistance force. Remedy the force by mounting to heavy duty rubber, and attach the rubber to the frame. That will limit the force visited onto you blade.
This is a really good idea! The dual stage filter is an idea I'll steal! Maybe a motor with a wheel and offset crank would be more reliable (like a piston engine). Using a washing machine motor would be really cheap.
The blade breaks because it is hardened high carbon steel, you have to soften it by heating it to glowing red and then cool it slowly, in a bucket of perlite or sand or dirt.
what if you had a rope viced into the sawzaw and attached to the screen frame? A bungee cord or spring on the opposite side to keep the rope taught. That would get rid of the blade breaking issue. The rope could go through a pulley too to change direction of the pull if needed.
A bees dick I have to remember that one! Sort of like the R CH and the B Ch!🤣 someone explained to me the other day how insignificant a subject was that was being discussed as a tick turd! 🤣🛫
