Making Dog Holes

>Seems like your holdfasts will loose a possible bearing point if all the holes fall on a reach pattern. I might have them 2x width, you can always add extra holes latter.

Also one thing I do is place them where I want them Like I want one to hold a piece for mortising over a leg of the bench. If I just do a geometric pattern I would be pretty upset if none of them where exactly where i wanted them. I can always put a gobar anywhere so I don't put many holes in my bench.

That's probably a good idea, and good reasoning.

What's a gobar?

T.O.

One other alternative

>It's a relatively small bit of wood that you brace against the ceilling. If you are going to use this a lot it's nice to have a board of wood mirroring the surface of your bench, on the ceilling. You trim the stick so it bends as straight as you can get i and still have a lot of down thrust, maybe a 10% bend. I put the top on the ceiling above the point I want to hold down, and I push the middle away and push the middle away while supporting the bottom above the board until I am over my point. In some case it will get in your way, but you can also put it right in the middle of something huge, even use a bunch of them to laminate.might be a softwood stick about 5/8" x 1.25".

>That's how some brace guitars, as you know. The bigger gobars will hold your slab of wood for planing and wacking on, very cool technique. The holdown pressure is at least as good as hold downs.

space them for 45� ?

>alternatively you could space the rows of dog hole so that the holdfast pads meet at 45� rather than 90�

Why not?

>make up a plywood template with four holes in it. Mark and drill the first pair, insert dogs in them, mark and drill the second pair, move the dogs up the bench, and so on. BTW, I did ask a dog question in my last email.
