11. CHOOSE A TENSION STYLE
1.
Choose one of the standard tension styles and then follow the illustrations and instructions shown
below to set up your Flatiron wheel.
2.
To fine-tune drive band tension, spin the thumb wheel on the MOA tension control (installed in Step
4.6) to move the flyer assembly out relative to the drive wheel, which increases the strength of the take-
up, or to move the flyer assembly in, which lessens the strength of the take-up.

12. ADJUSTING / REPLACING THE DRIVE BAND
1.
Removing or replacing the drive band on your Flatiron is easy. Remove the 10-24 x 1.25" machine
screws, axle washer, 3/8-16 thin lock nut, and front axle bearing (see Figures 12.1–12.4 on page 16).
2.
To remove a band:
Pulling from inside of the front frame, take the drive band down from around
the drive wheel and towards the treadles. When the drive band stops, roll it off the edge of the axle and
remove it.
3.
To install a band:
Starting from the inside of the front frame, feed the new drive band into the oval-
shaped hole where the axle rests, looping up and over the axle and back to the inside of the front frame.
