Given all the discussion about how to fit "tightly fit" a 3/4" post into the MM sized MFT table top holes is Festool likely to provide a product? ???
 
We have been hoping Festool would make some bench dogs or something to fit the holes. So far, no luck.

This might a good thread to convince them to start. I'm willing to buy 4 bench dogs right now.
 
Actually, Festool does market such a bench dog !!
That's the fixed part of the flat fast clamp which you can buy as a spare part,
or better buy as part of the complete  flat fast clamp.

The simpler solution I mentionned is also meant for other purposes
as discussed in the related threads.
 
Mohrab,

Any reason the clamping elements or other solutions offered don't work for you? I'd like to learn more about what exactly you need and what you need it for.
If it is only a piece of plastic, there are probably solutions out there already. If you have ideas on how to add beneficial features to a benchdog, I am all ears.

Thanks

Christian
 
This is what I am attempting to tool up to manufacture...

Don't know if this is what others have in mind, but with a bolt thru the bottom and a cam clamp on top, I will be able to affix jigs made from 3/4" material (and drilled to match the MFT's holes) readily to the MFTs top.  My prototype of metal and rubber washers works great for what it is, but when I get these parts made, I will be a happy camper.  

If you would like to discuss this directly, do feel free to call.  I would be more than happy to assist in the design of this (or any) part if Festool USA would like to offer such.  And for no charge.
 
As has been said, the stationary part of the the clamping elements is an excellent bench dog. However, it would be great to have a lower profile version for thinner stock.

Corwin, your design looks very good. The only improvement I'd like to see is a generous flat area for holding softer pieces.
 
Good point. For those interested in using the 20mm PVC pipe, there is an easy and cheap
way to add a flat part of the width you want.

Take a small square/rectangle made from anything suitable scrap, MDF, plastic, whatever,
width of of your workpiece, and copy yet another 20mm MFT hole in it.
Then plug a PVC pipe across its hole and a MFT hole. Done.

Can also cut the rectangle in two equal parts, along a hole diameter.
so you get two pieces, each with half a hole.

Probably worth to make a number of these animals at once.
Copy a region of your MFT hole pattern on a wood rectangle,
then cut this reactange into smaller  pieces.

Pretty easy and cheap isn'itPr
 
Actually, this is just what I drew up using SketchUp late last night -- only the second try at using that software, so this drawing was just a quickie.  

I am also interested in pieces with a flat mounting element to them, but this was to be my first cam clamp part, along with a shorter version, that I will use in conjunction with Incra's brackets for their Incremental Track.  This has been my focus since I have been able to get around better...  I've played a lot with mockups and have attempted to begin a machining station with the purchase of a metal mini lathe -- should be working, but support is lacking and after a full month now I still have a 'new' tool that is not completely functional.  And people complain about Festool???  My experiences with both Festool and McFeelys has been the best customer service I have ever experienced -- from anyone -- ever.  Back when, my father ran his business like this, and many clients changed from obtaining bids to just giving us a call.  I do enjoy working people when my experiences are such, as over time I have also elected to not do further business with companies that just don't care.  Sorry for the excursion, so I'll move on...

The cam clamp is similar to Ned's MFT: Cam clamps, only using two or three rubber washers for the expanding element.  I feel that this or similar units need to have an portion above and below these rubber washers to best locate within the hole in the MFT itself -- additional height above the MFT's surface would accommodate the thickness of any fixture one would attach.  The portion above that can have flats for further mounting purposes.  Yep, we are probably on the same page by now...  Well, at least I hope so.

I'm open to suggestions, as always.  My interests are simply that, in that this is something I am personally interested in and will work towards anyway -- but, I do like the company   :D

Have a nice weekend,
Corwin
 
I just needed a flat part for one of my PVC dogs, so I made it as described.

These pipes are also handy to store pencils, a caliper, clamp bolts, etc ...
