Whenever Ive made sliding box sash windows, I always have the same issue.
The problem is what tolerance to give on the parting bead groove.
Generally I machine the groove to 8.8mm for an 8mm bead - but the tightness of the bead varies - from slack Alice to Tommy tight.
I spray 1 primer coat and 2 top coats with waterbased joinery paint
Anybody find the same issues?
I believe Mumford and Wood do tapered groove and tapered parting bead - which is an option I guess
