Problem solved!

Like I wrote yesterday, I had a small problem. As soon as I put a clamp on the cheeks of the sawhandle, it would bow the end of the sawblade a little bit. Not enough to really worry about, especially as you never use that bit of the sawblade under the handle. But it bugged me nonetheless. First I thought I had the mortice off kilter, but inspection showed no troubles there. Then I looked very closely at the blade groove, whitout a clamp yet,  and saw this. On one side it was tight against the blade, at the other side there was room. I used an offcut from the blade as a scraper and scraped away a bit of wood, inside the groove. Problem solved!
