    I have plans to make my wiper arm tomorrow. I was thinking that I would make it 3 inches hole to hole, meaning that it woudl be 6 inches from farthest point to point, So top and bottom.

    Are there suggestions out there on this? I assume that a longer arm would equate to slower reaction but longer movement.

    What is the experienced aproach to this?

    Longer arm -> faster movement -> less power.

    Don't expect an exact answer because we have no idea. Make the arm longer and drill more holes in it at 1/2 steps. Then start playing with it and figure out which hole works the best with your geometry.

    Thanks frakk, think i mixed up the length to speed piece. Yeh im planning on welding bolts on my arms, i'll step them out at 1/2 inch increments, thanks. didnt know if there was a general length folks shot for.

    be careful - if you weld bolts all along the arm, they may reduce the range of movement, and will certainly stop the motor from rotating completely (the bar joining your arm to the frame will have a bolt on either side which will foul it as the motor arm spins)

    you would be better to drill holes as frakk suggests and use a bolt through the arm until you find a setting that works... then weld it ;)

    thanks Tim but I have big cruising for a while! =) I went with the original motor arm, I find it fits the screw head the best and it gives me good range of motion, you dont really need to go that far to get the right feeling. I have about 4 1/2 inchces of travel, maybe a little more. tahts works well for me!
