Just wondering so I can plan ahead. I’m going to be building a workbench in the coming months and I’m collecting parts and pieces now. I was watching Woodsmith Shop’s episode on Benches today, for the umpteenth time, and the units they were using on their bench used 3/4” holes. Also, the square, flat faced dogs, is there a set size for those also or is it something I would buy and build the bench holes specifically for them?

I think bench dog are 3/4” in north america and 20 mm in europe. I have some from France and they are 20 mm (a little bit over 3/4”). My home made are 11/16”, I cannot say what is the standard but they fit perfectly in a 3/4” hole.

There’s no standard size in either round or flat. But the veritas dogs are 3/4
I have the gramercy holdfasts… excellent, also 3/4, but I have a woodcraft holdfast for my old bench and it was smaller. if you are going round, then 3/4 would be safe in the USA and Canada, if you are not then I’m not sure.

Square come in all sizes as most are home made. I have seen square dogs for sale, so you would have to do your own research, but you are correct to get it all together b4 you build. Good luck a good bench is a big asset. My old bench can not compare to my new bench. A solid bench adds a lot to the precision of what you build.

And please see:

Thanks You for the replies. Very Much appreciated.

Good info on the video, I hadn’t really given it much thought but the design I’m working on would take care of all that. I’m planning on actually having a stretcher at eh bottom and the middle. The bottom one is because I’ve found that when I’m standing at the tables, I like to have a step up, similar to the idea behind the foot bar at saloon bars. Also, by design, I’ll have a mid-height stretcher that will support a shelf

Have your say...
