1. Hold the M2 sled against the wasteboard
near the right chain. Hold it against the frame
with your body weight or have a friend help
by holding it for you. Take the loose end of
one chain and thread up through the hole in
the roller bearing carriage.
2. Insert the
cotter pin
, with the flat side on
the right, into the second to last chain link to
attach.
3. Manually move the M2 to the center of the Wasteboard and have a friend pull the tension
on the opposite chain to around 20in from the nail to the spring. You can pull the chain
away from the motor sprocket, pull for more length, and set it back for the tension to hold,
and beware of it snapping. When you have enough slack in the chain, thread through the
opposite roller bearing carriage and attach with the other cotter pin into the second to last
chain link. Let go of the sled and it will rest against the canvas.
Drew’s Note: We recommend wearing safety goggles and having a friend help mount the sled to
the frame. The chain can slip off the sprockets, causing the spring to snap and hurt people, pets,
and surroundings. It’s also important to insert the cotter pin into the second to last link, for extra
safety of the chain attachment, as shown below.
Drew’s Note: Your M2 is ready to
calibrate! (Also, don’t forget to
securely attach your bricks with the
Velcro straps, if you waited until it was
mounted).
