Boys and Girls,

Since I bought my TSO Power-Loc Dogs around 6 months ago, I have been spruiking them and may have portrayed misinformation of them.

Personally, I look upon them as a ”profileless clamp” to hold jigs

and other paraphernalia

to MFT style benches/tabletops.
They are not the “traditional” type of a bench dog.

Nevertheless you can convert them into a bench dog by drilling a 20mm hole in a block of wood, chamfer it and use the TSO dogs,

to anchor them to your bench. They can simply be inserted into a dog hole, however, I recommend that they be tightened with an allen key… or using a cordless drill on the lowest torque setting,

(another tip and this one’s a freebie).

They can then be used as a dog stop,

and for thicker benchtops recess the chamfer deeper,

to compensate.

Unfortunately if you want two dogs (no joke intended), unless you are meticulous with your measurements and subsequent execution, you could sacrifice the MFT style feature of your bench due to incorrect centering of the dog in the timber.

I have managed to find a workaround for this… the downside is that for 100% (+/- 0.05% mm) accuracy, you’ll need access to a laser… a CNC may suffice, however, the potential tearout/cleanup may jeopardise accuracy.

I have designed and cut out these collars from 6mm MDF.

That can now now be substituted for “normal dogs”

using the TSO Dogs and the drill,

You can stack the collars according to requirements and the thickness of the benchtop

Because of the accuracy of the laser, you can be guaranteed that on any spot of the collar perimeter, you’ll be exactly 15mm from the centre of the dog hole.

With such precission, you can maintain the integrity of the MDF style concept of your table top. This perfect 90° corner fits precisely against the dogs,

Now I appreciate that MDF can throw wobblies when subjected to humidity changes, however, all the collars being identical in size, should be equally affected creating a proportionate margin for error that will retain integrity.

For the faint hearted, I have created a set of collars out of acrylic

that will not be affected by even spilled vino… you may cuss at the loss of the savoury brew but not on its moisture affect on the dog collars.
To compensate for the laser kerf, the OD was 30.3mm and the ID was 19.8mm to yield a 30mm OD and 20mm ID respectively, collar… as can be identified by the engraving on the collars.

I have also made a set of 25mm collars


to fit the TSO dogs that can be used instead of the supplier’s recommended Veritas dogs for use with the UJK Parf System Mk.I


the one on the left is the recommended Veritas dog... or if you just want a 25mm dia. dog if you are kinky.

As I’ve mentioned in the past, don’t be threatened by the mention of lasers… laser cutting per se, can be relatively cheap as the majority of the costs is in the design and setup. If you provide the specs and material, I am advised it’d probably be cheaper than the petrol used to drive to the service centre… and if you have access to a laser, then you’ve got no bloody excuse!

I have made another of my impromptu videos and all the files I used can be plagiarised using this link.

Don’t let the original ”collarless” limitation deprive you of extending the versatility of your clamping horizons using these dog clamps. You can now have a bench dog that bites (clamps)... and barks (“dogs”).

Keep safe, jocks... and your jocks, safe!

And thank you for introducing me to the word “spruiking.”

Never knock what you haven’t tried… that’s why I only just make snide whispers about the Bos¢h sander lately.

That’s like the 300 Spartans who said they don’t need a Pfeifer-Zeliska . 600 Nitro Express Revolver and chose swords and spears instead… but if they had a couple of those “little” babies… even just one…. they could’ve reversed the tables on Xerxes, and all the middle east would be speaking Greek.
