Thank you so much for this detailed reply.
I’ll cut 7/10cm(2 and 1/2 ” to 3 and 1/4 “) wide of two slab glue end together edge to edge to get a representative length (slabs are around 40 cm wide/ 15 inch and 3/4) and give it a shot.
I see many opportunity to scr*w this pretty hard, but trainning on scrap sure is the way to go.
I intend to work with chestnut, any particular recommandation you would dare to add?
Thank you so much again.
I’ll post photo to track the mess 😀 (hopefully not :D)
