Heh heh, neither had I until Ratbag used it. Google is our friend:

Of course it's always wise to check, Brett, but I reckon it's one of those great words that just sounds like what it means...
Cheers,

Had a couple of hours today and started making a simple jig to drill my dog holes. Basically it's a bushing to guide a forstner bit and will locate the holes at 96mm centres using a thick aluminium rules which will have holes drilled every 96mm and 5mm locating pins. May work. May not. We'll see.20160820_175323.jpg20160820_174501.jpg

Milled up the 32mm spaced holes in a thick aluminium straightedge this morning. Tried a few shallow holes (didn't want to blunt forstner on plywood glue) and seems to work ok. Give it a try on the workbench soon. Just need to work out a good accurate way to ensure perpendicularity and parallelism of all rows of holes. Maybe another two straightedges with holes at the right distance and using pythagoras.

I think your clamps and hole drilling jig look awesome. I also have some dogs just like the first lot you made and I use them every time I'm at my work bench. I use a Festool table so those dogs and clamps are ideal.

My dad made my dogs for me, and I will show him pics of your clamps in the hope something similar will magically appear soon.

Haha. It's funny that so far my metalworking machines have only magically made jigs and tools related to woodworking!

So i started to drill some holes. All good so far. Although my forstner bit does not like going through MDF. Its taking a while.

Also, ive so far left 192mm between holes. Should i drill the in-between holes and go with 96mm or is 192mm apart likely to be close enough. 192mm doesnt seem like too far between holes... but who knows. It'll be easier for me to drill more now than to come back to it.

Advice appreciated.

Your jig looks excellent DomAU.

I think I have a similar spacing for dog holes on my main workbench. The idea was probably to space them according to the the adjusting on my twin screw vice?

Winding the vice in and out can get tedious so I often just use a board to take up most of the space.

You might find that you are using one part of the bench more often and you will add the additional holes to that area.

Some good ideas here.

The maximum spacing of you're holes shouldn't need to be any closer than the distance of you're open and closed dimension between the jaws of you're vice that is clamping against them. I love you're jig set up very well sorted.
Regards Rod.

Thanks guys. I drilled out the holes this weekend. Worked out well. Holes are inline, parallel and perpendicular within a small fraction of a mm (aside from one stray hole haha).

May add more holes along the length if i feel i need it.

Probably the most frustrating part was the carbitool forstner bit. I like their router bits and have found them to be of high quality however i was disappointed with their forstner bit. I even had to re-mill the hex so that the bit would run concentrically.
