Bench dogs for the 20mm holes - reviews, 3d printed, upgrade and ramblings.

Bench dogs for the 20mm holes
reviews, 3d printed, upgrade and ramblings.

I bought some new dogs for my worktable a few weeks back, some 3D printed plastic and some in precision made aluminium and wanted to make a short review and share some thoughts on this.
Nope it was not Chihuahua…
The plastic version was mainly bought to use for fixture of jigs and other stuff to the table and because I was curious to see them. ;-)

Here they are.
Green 3D printed plastic dogs, from a seller called Yumiland on E-bay UK, price 20GBP for all of them, including the low spacers.
Aluminium dogs and extenders, from the Danish tool company , 44GBP for 4 low dogs, two extenders and two FS track washers that converts the extenders into guide rail dogs.
All dogs are threaded with M8.

Just a closer look, to see the quality.
I screwed the extenders on top of the aluminium dogs here, they can be screwed under also or you can put the nuts you see in the plastic bag and use them to lock a FS track saw track or a Festool fence to the table, for fast and easy removal.
The black dog on the left is one from a workmate type table and the one on right Festools original dogs.

Here some of my early home made fixtures.
20mm aluminium rod with a rubber top.
Jig holder, with plasterboard fixture that goes through the holes.
The most simple one, bolt, washer and wing nut.
The problem with the holds, was they were not centred up with the holes, when I needed that, otherwise they are more than enough.

I'm impressed that you can 3D print this stuff, but not impressed that there were an edge on the top, this made the things you put up against it off centre… Grrrrr, why did they not just do like on the bottom made a little rounding, so the edge would not be a problem…

Ok, it can be fixed easy, just a short piece of 8M rod in the drill press.

A washer and the dog.
Spin it and with sandpaper or a file remove the edge and round it a little.

Like this.

Now we only have the small lines on the sides that stick out a wee, these also have to be filed off, to make sure the dog are flat to the work piece.
Also the part that goes into the bench, otherwise you risk making damage to the holes in the MDF when pulling them out.
So yes a wonderful value for money, but not ready out of the box - I still think the price are so fair, that spending 20 minutes fixing them are well worth it, so I can recommend these.

Here the aluminium dogs, I'm pleased with the quality.
The flat side on the dogs will help you not make marks in the things you put against them, but they can also be the opper side if you bang into the sharp corner… so a matter of taste - with this type you need to make sure they are flat against the workpiece, when using flat side.
The extender can be used in many ways.
(I have a feeling the dogs are a tiny bit too small since they moves almost too easy in the holes… but it's so little that it's almost nothing).

I found a big washer and a M8 finger bolt to match, so I could tighten them down.

This can also be used on the plastic dogs.

Sawing with dogs.
Put the wood on the table against the dogs - a dog with extender on top and one further up the table.

Now the track can be put against the extenders.

Now you will have a perfect 90° cut.
This is fast and functional if you don't have the track mounted on the table or 45° cuts where you position the back extender in the 45° line of the holes.

I quickly found some bigger finger screws, the small were a pain in the some where dark.

That's it, no more ramblings about dogs, big smile.

Hope it can be to some inspiration, wrrrouuuffff.

Best thoughts,



bench dogs, festool bench dogs, rail dogs, mft3 dogs, festool dogs, festool, mft3

COOL work…

Question: Why weren't the 3D Printed dogs designed with the threaded holes so they would not have to be drilled?
Using Fusion 360, the threads could have been included in the 3D model.

Interesting approach…
