Dog Holes?

[phil p]

Hi,

Still cracking on with my bench and thinking of putting dog holes in the the top and possibly in the legs.

Could I ask what diameter/size they normally are, and also is there in rules as the where you place them, distances etc?

Any other info/advice would be appreciated.

Thanks
Phil

I'd make them match the dogs you are planning to use. Round or square etc
As for pitch maybe 200mm grid. If you will also used them with your vices, then the pitch needs to be just less than the travel of the vice jaws.

For round dog holes, the most common size is probably 3/4" (19mm) diameter, as this will take all of the very useful Veritas bench dogs and holdfasts such as those made by Richard Tomes. Richard Maguire has an excellent method for drilling the holes vertically

I find that several rows of dog holes are useful - I have five rows on my bench top



The spacing between the holes depends on the type of tail vice you are using. Best to have the distance between the holes slightly less than the opening in the vice.

Cheers :wink:

The dog holes in my bench tops are 19mm and at 100mm centres along the bench in two lines, if I make any more benches I will space them no more than 230mm wide across the bench top to use these which are great.

For the holes in my bench legs I use 25mm holes at 100mm centres for supporting large panels and doors.
For your information big Vic from Veritas will be demonstrating at our workshop and tool shop on Wednesday 25th September in the afternoon all welcome.

Thanks for the replies lads.

Sorry I forgot to ask when I posted, which would be the best type of drill bit to use?

Thanks
Phil

That R.Maguire tip is sound, but personally I would use a newly sharpened auger rather than a lip and spur. Augers are not difficult to sharpen, and cut much more cleanly when sharp. If you were being ultra careful, you could clamp something on the underside to prevent any spelch.

I have based some of my benches on the festool mft tables . The top is a torsion box with 20mm holes at 96mm centres. This one is seen attached to a hospital bed to give height adjustability. Holes cut with a router and guide bush.

Hospital bed!... What a great idea! =D>

Can I ask...is it sturdy? Does it wobble?

Its pretty sturdy to be honest and does wobble very slightly in use. It was intended as more of an assembly bench but its possible to handplane on it the biggest advantage to me is being able to move it about and change the height easily.

Theres a thread here showing how it was made http://www.woodworkuk.co.uk/forum/viewt ... f=9&t=9644
