Topic tags/keywords: moulding knife cutters

I am in the process of reworking over 30 pairs of double hung windows to fit new jam liners. I am wondering if a set of custom moulding knives would simplify the process of re-cutting the window stiles but I am concerned about safety. Because I am working on complete windows they are not really easy to guide on more than one side and the bottom.

Currently I have been making a dado cut (0.165” deep x 0.664” wide) in the stile and then routing a 30 chamffer on the sides of the dado like the drawing below.

Does anyone have ideas on a safe and simpler way for me to make these cuts?

I decided a safer way to make the profile cut was a customer router bit and power feeder on my router table to help process the large windows. Expensive router bit it works great…still cheaper than buying all new windows.

Have your say...
