M2 ASSEMBLY GUIDE
Warning: We recommend wearing safety goggles and having a friend help mount the sled to
the frame. The chain can snap back causing damage to self and surroundings.
STEP 1:
Hold M2 sled against the Wasteboard near the spring and hold it against the frame with your
body weight.
STEP 2:
Take the loose end of one chain and thread through hole in the Roller Bearing Carriage built
in Step 1 of Mounting Sled Brackets.
Insert cotter pin to attach chain to M2 into second to last chain link.
5. ATTACH M2 TO FRAME
STEP 3:
Move M2 to center of Wasteboard and have a friend pull the tension on the opposite chain
to a length of 20” or less (from the nail to the spring). You can pull the chain away from the
spring and lock onto the top of the motor for the tension to hold.
When you have enough slack in the chain, thread through the opposite Carriage Mount and
attach with a cotter pin.
Let go of the sled and it should rest against plywood or MDF. Your M2 is ready to calibrate!
Warning: Beware of chain tension! We recommend a friend help connect the spring and
each person wear safety goggles during stretching. The chain can snap back causing
damage to self and surroundings.
