I got the plans and it looks ok so a few of us local guys chipped in and bought the material. We are going to start building it today and any help with changes or trials and tribulations that you have encounterd would be helpful. Thank's in advance

If you use .5 inch materials you are going to add reenforcments. Don't stick weld the disk to the selector rod. It warps and screws it up. Make it air tight so you get accurate readings. Repeatability in the readings is important. Don't wet flow with it. I'm still working on mine so you might shortly learn more than me. Visit the dyno/flowbench forum if you have the address. Those guys have real world experience that I can't supply. When Bruce gets the archives up you will have more info than you need. Also, one of the sharp edge orifaces is wrong. Don't remember which. I plan on making about 4 oriface plates calibrated to the flows I want and will bolt them into the upper plenum as I need them.

FYI the SF600 and another popular brand is basically the same setup except that they cost thousands and are really pretty.

Thanks for the plans and info. Thought the same, about making a few orfice plates for better range and more accurate results. We live in a dairy area so it is easy to have someone calibrate each orfice with a vacuume and flow meter used on milker pumps. Useing 16 ga for the orfice plate, I'll just tig weld it then. We got along way on it today and will have the motors and relays tomorrow from granger. Bought 8 motors, should be plenty for tractor stuff. Lots of intrest from everyone that I have told about it. I will post a picture when completed if I get the computer and camera figured out

I should have tig welded. I had a disc cut on a CNC VMC but screwed it up welding. Locate someone with a superflow and have them calibrated that way after it is finished. I might have free access to the SF600 equilivent late this spring so you could ship me your plate and get it done for free provided everything works out.

I have read that you can get false reading if the oriface is directly under the adaptor plate that sits on the top of your counter. There should be some sort of offset to correct this.

Visit>Link
which>Link will redirect you to the new board. You will get all the answers you ever wanted there plus formulas for converting the numbers. Also better designs and the one incorrect flow number on one of the orifaces. Maybe Bruce will have the archives up soon.

may just send you a plate or to, will keep in touch, probably be makeing the plenum's and mounting motors tonight and plate should get machined today, will offset it a little to one side and the test hole to the other side just slightley.

The ultra copper holds really well. Put some weight on them and let them sit overnight.

Glue every joint and use long screws. After you get it working, weather you nail down an actual certified flow number you can still see improvements, shoot me and emial and I'll send you some articles.

Think about making a velocity probe, (3rd manometer attached to a tube attached to your u tube probe. Also the string on the end of a welding rod (or whatever) to introduce into the port to see where the air is flowing laminar/turbulent. Also a round bead on the end of a welding rod (stainless is better if you can locate something thin) then watch your inclined manometer. Steel your kids playdough or get some modeling clay. You will have to make an entrance to the port weather it is a head or intake. Search Brazenski (spelling?) adaptors and look at their plexi glass adaptors. A rounded edge prevent the air entering the port from shearing and causing turbulance. (sorry about all the spelling)
