Woodruff key question

Does anyone make a woodruff key that uses a 3/16 lower half that engages into the crank but a 1/4" width where it goes into the balancer?


I have a balancer that came off of a callies crank that uses a 1/4" key slot, but switched cranks to a winberg that uses a 3/16 key slot.

Option A is to use a staggered key, option B is to replace the balancer. Obviously the key would be cheaper.

Can you have one machined?

Thats weird, I know they make a 1/4 x3/16 key but is opposite of what you want, 1/4 normally goes in the crank.. I guess you could flip it upside down. Summit has them, you might check with Specialty fasteners too.
I just got a Winberg crank and its 1/4 key but I specified duel 1/4 key.

Since you said balancer I assume you are talking the straight key and not the 1/2 moon key for the crank gear

Woodruff key is the half moon key. But I bet you could machine or possibly buy one of either type.
