Cord groove

All the way down each side of both sashes the cord groove is routered.

Although the cord will only go about 200 down the sides the groove goes all the way. This can help stop water being driven on to the brush seals.

To make this a little steadier to cut, as its on the full glued up sashes, I knocked up another large fence. I'm sure it'll come in handy for other jobs.

I also need to widen the groove at the top to allow the pulley to pass. I'll wait until the hardware arrives to figure out the dimensions.
