Here is the link to my facebook page. http://www.facebook.com/video/video.php?v=10150179367021001&saved#!/video/?id=693001000
if the link doesn't work go to facebook and look up Shawn Cote. My picture is of the exorcist :D
Its the only way I was able to get my video uploaded.
The pump is made using a hand diaphram pump purchased from Princess Auto ($60)
I used a 1HP 120v treadmill motor (princess auto $50)
The motor only turns at 1750 rpms so I built the plywood box to house two axles. On the drive shaft of the motor I used a 1-1/2" pulley and that drove an 8" pulley on the first axle. This reduced the speed of the first axle to 328 rpms [(1.5" / 8") x 1750 rpms]. On the first axle next to the 8" pulley i installed another 1-1/2" pulley. This pulley drove a 7" pulley on a second axle. This reduced the speed of the second axle to 70 rpms [(1.5" / 7") x 328 rpms]. I welded a piece of steel on the end of the second axle with a bolt welded half of the stroke of the pump away from the center line of the axle. (sorry its a mouthful and kind of hard to explain). I made a vertical shaft to connect the pump to the now rotating bolt.
After trying the pump out, I realized that the check valves inside the pump were not strong enough to overcome the suction and pressure that was being produced so I added 1-1/4" spring loaded check valves. Now I was ready to start testing with water and thats when I tore my first diaphragm :mad:. At that time I was using 1/2" suction and 5/16" discharge - bad Idea. After putting 1/2" line on the discharge things were working well, and producing a constant 15" hg.
Feeling like I just conqured the Maple Gods, I ran all my lines outside and hooked up my new born sap puller. It only took about 3 minutes to realize that I had a problem, the v belts were slipping :mad:. Trying to remain calm, I ran over to Canadian Tire and picked up some belt dressing spray. This was a fantastic band-aid to my pumps injury, so I thought. Of course the belts starting slipping again. This is were the hight blood pressure starts :). After picking up all the pieces of my pump and nursing my now sore foot I reasembled the pump but this time using chain and sprockets. Now shes a TANK.
I have 500 feet of 1/2" mainline and close to 500 feet of laterals/drops etc.. for 62 taps. At the furthest tap on my line I have a constant 10" hg. Not to bad for my first year of sugaring. OH, I forgot to mention that the chain fell off the first day so I changed the discharge line to 1" and she works great now.
If anyone else wants to try to build one, think big and think strong. 10" hg can cause a lot of straing on parts.
