Rebates In the Beads for Brush Seals

The beads also take the brush seals so a rebate is needed to take the carriers.

The TS Tb and BS Bb are 2mm deeper than the carrier so the pile of the brushes don't get crushed flat when the sashes are shut.

All the side bead rebates are are as deep as the carrier, I'm aiming for 2mm clearance each side between the sash and frame.

CUT the BS Bb, TS Tb and TS Bb to width using the width stick from earlier.

Then rebate the ends of these.

Note: Don't be a dummy a second time. Cut the rebate on the TS Bb on side opposite the brush groove. (not shown in picture)

You can see here I've made a 90 degree angle block to do these rather than have to set up the cross slide.
