Tagged: wedge; mortise; tenon
Am crafting some through tenons in softwood which I intend to wedge, and was interested in advice around how much to ‘dovetail’ the mortise.
The tenons are 1″ thick, 3″ through and 2.5″ wide, and I’m thinking:
(a) Two saw kerfs, about 1/2″ in from ends, going about 2/3 of the through length of the tenon, angled 1:7 or so ‘inwards’, with 1/8″ or so stop-holes;
(b) Wedges in hardwood, about 1/3 length of through tenon, and about 1/4″ thick at wide end
Each kerf will be about 1/16″, I was thinking of about another 1/16″ for the ‘dovetailing’ or widening of the outer half or so of the mortise, giving me about 1/8″ to ‘fill’ plus the compaction of the tenon (as it’s softwood) making the 1/4″ wedge about right?
Does this sound right to people?
Thanks.
