Hi,
I am building a Pentz Cyclone with the Sheldon Fan and the Leeson
Motor...I am TRYING to attach the Sheldon fan to the Leeson motor
shaft but it is not working that well...
Is this correct?
1. I reattached the JA 7/8" compression fitting to the bladed side of the fan,
just so perhaps 1mm of the compression fitting stuck into the fan and pushed
this onto the 7/8" Leeson shaft making sure the key slots lined up.
Then I tighten the 3 allen head bolts so that it pulled everything together.
Then I inserted the "key", and tightened the allen set bolt.
Now the compression fitting is "in" the fan perhaps 5mm (0.5cm), looking
from a side view with the compression fitting being a "T" resting upon
the fan, the distance between the bottom edge of the top of the "T" and the
fan is 1cm or about 3/8". Does this seem correct? It seems like
a really tight fit---but I wouldn't want the fan to fall off.....
2. The Sheldon fan is made from steel plate which is welded. While
the workmanship is as good as can be expected, the bottom of the fan,
the "disc" is not "perfectly" flat. Now the fan is on the shaft, there are six
segments on the fan (between the blades) and the distance between the
bottom of the fan and the blower motor plate vary
slightly-31mm, 31mm, 30mm, 31mm, 32mm, 31mm. When I turned the
fan on--WOW its very powerful!, it seemed OK-no wobble that I
could tell.
3. I made the blower according to Pentz' plans with MDF top and bottom
and sheet metal sides and long bolts holding it together. IF the fan
fell off while running, would this "blower" keep the fan inside it? Or would
the fan break though the blower and perhaps harm me???? Would the
Echols blower unit be a much better option for this reason? Is the fan coming off a real concern?
4. Mounting...what works better:
A. Attaching from the motor base?
B. Attaching from the motor plate?
C. Making a frame and supporting the "waist" of the cyclone?
D. Other?
Thanks so much--any help would be appreciated!
