Thats a good idea - a slot ! Not thought of that. The ebony is the problem - I think maple should spring around if dampened and clipped to a curve and let to dry. I am trying it with some ebony @ 2.4 x 0.85.
Maybe the same effect as a slot would be just to clamp a plate 1mm above the flat top of the iron with a metal packer- just need two flat plates of brass staggered 3mm on a curved edge profile ?
Simonm - thats link is dead to me - get the site a but blank frame ( may be a problem with my end - Flash version ) I've not see that video before ?
Sidebender attachment - mk1. Three plates of ally laid up together loose, bolted to lower lug.
( the crack has is an old one - needs pinning sometime )
The trial ebony was 2.4 wide x 1mm. Slot is 1.4mm - needs changing to 1mm or so - and smoothing up on the upper and lower plate edges
Works well !
