I have no idea which expert to ask, the question relates to a bench I am making, it is based almost exactly on the bench in Lon Scheining’s book “The Workbench” pages 158 to 161, using the same vices.
The difference is that I am adding a tool tray in the center of about 7 inches wide plus I will be using thicker stock – so in effect i will have 2 sections, each being six flat sawn boards 4×2 inch American Hard Maple 66 inches long laminated to give me slabs 12inches wide x 4inches thick x 66inches long (after Routing dog holes etc).
The above will then be assembled with End Caps (End Caps will be attached with long mortise & tenons plus 2 bolt, 1 nornmal & 1 slotted for each slab plus Front & Rear face “skirts” of the same stock but 6 inches deep, I will as in the book be using Half Blind dovetails.
The tool tray will have “ramps” on each end, probably attached to the End Caps & will be around 1/2 inch wider than the tool tray, the main slabs will be inlet to overlap the “ramps” to allow the main slabs as described in paragrapgh 2 to movement passed the “ramps”, the base of the tool tray will a slide out affair as per the “Veritas” bench.
I will be using a normal cold glue with a relatively long drying time to laminate the 2 main slabs ( to give me time to get it all correct before clamping), the slabs will be correctly clamped with enough clamps & caulks to sink the Titanic.
Question 1) Should I also use countersunk through bolts on the individual slabs – say 4 bolts accross the 66inch lengths as used on the Marlof bench?
Question 2) Should the through bolts also go through the front & rear 6 inch “skirts”?
Question 3) Should I simply do nothing & trust the adhesive?
Obviously, i would not tighten the the through bolts to death but simply snug them up after clamping & applying some kind of Locktight to keep the nuts in place.
We have dry winters with virtually no rain for 3 months & moderatly wet (around 300 inches of rain) throghout the 9 months summer in Johannesburg, South Africa.
I waited over 11 months for REAL American Hard Maple for my bench & would hate to have it delaminate after a few years.
