TSO 20mm Workholding Accessories Review

[kitui]

I would like to buy the TSO Dog rail combo pack (dogs and clips) but now that I read about a shorter version that does not interfere with the TS55REQ motor, should I wait? I do not see the stubby dogs on the web site yet. Please advise. Thanks

to all: re Stubby Dog
we will announce availability details via the TSO INSIDER newsletter. Expect approx 60 days from now for availability

I really cannot wait that long. I will hung in there with the long dogs.

Just cut them shorter with a hacksaw (angle grinder if stainless steel).

Hans,

What about the close tolerance dogs?

Thanks
Jack

Hans.

Will those of use who receive your news letter be notified when the close tolerance dogs are added to your website? I would like to get a couple of them.

Thanks
Jack

All:
CT-Dogs, the newest addition to our workholding line-up, will be available to order and ship sometime next week after 1-31-2018. We will also notify all PARF GUIDE SYSTEM Purchasers via the TSO INSIDER newsletter of the availability of free exchange CT-Dogs.

So can I swap my tall rail dogs out for the stubby version

[member=65062]DynaGlide[/member]  - give us an opportunity to get Stubby Dogs produced, in stock and up on the website sometime in March. We'll figure out the best ways to serve customers who have other versions of Dogs and also want Stubby DOgs.

The TSO INSIDER will have more as we get them in stock.

[member=59331]TSO Products[/member] Sounds like you need to ask festool for the GD&T call out for the MFT holes. Knowing the tolerance they hold the table to, you could then accurately understand what to make the corresponding holes in your tools to. I doubt they would give up the manufacturing tolerances though...

Hi, I was wondering if these TSO dogs fit Peter Parfitt's Parf Guide System for drilling MFT top holes without slop?

[member=14783]jonathan-m[/member]- we have been working this Dog dimension and tolerances issue ever since we designed the TSO 18" Triangles: MTR-18 and PTR-18.
What we learned was that worktop hole patterns and tolerances vary considerably - even on original FESTOOL MFT tops. Not huge - but measurable. Machining our Triangles and the 20mm registration holes in them accurately with very close tolerances is no problem with our Precision CNC Milling Machines, - BUT - ensuring that the customer who uses these Triangles can get them to connect to his or her worktop is another matter.
After evaluation every conceivable Dog on the market and on the advice of some very seasoned Pro's on this very forum we settled on clearance tolerances for our general purpose line of Dogs. We recommend using them with knobs - ours or anyone else's - to help center the Dog by pulling the collar of the Dog snug against the worksurface ensuring a perpendicular alignment.

But there is more to this:
thanks to our friend Peter Parfitt and AXMINSTER's precision machining on the Parf Guide System it is possible for any woodworker to make their own very accurate hole diameter and hole pattern worktop.

To achieve the optimal accuracy the Parf Guide System is capable of, requires a very close tolerance diameter Dog.
We have just begun shipping these new Close Tolerance Dogs. To distinguish them from our general purpose Dogs, we have added a concentric groove in the top of each Close Tolerance Dog.
Because we see the need for both general purpose tolerance Dogs and Close Tolerance Dogs for use with Parf Guide System we will shortly offer teh Close Tolerance Dogs as the Small-CT Dog.

We have worked very closely with Axminster's engineering staff and talked with Peter Parfitt to help us choose practical tolerances for each application. We have more work to do to communicate with our customers on these points.

Keep the comments and suggestions coming - along with your orders, too  [wink]

good idea but, like you, I doubt Festool would give up their manufacturing tolerances. In any event, you still have woodworkers out there with various other sources of 20mm worktop patterns.

I have not seen any evidence that Festool claims the MFT hole pattern to be anything more than openings for clamps.

FWIW: the extremely precise and close tolerance Super Parf Dogs do not fit equally well in all the holes in our brand new MFT/3 top. Some go in easy, others I have to push hard and they are hard to pull out - evidence of variations in hole diameters.

Our CNC machined MTR-18 and PTR-18 Triangles with very precisely spaced Dog hole locations have Super Parf Dogs encountering various degrees of ease or difficulty in getting them to align with the MFT holes.

ALl this are reasons why we have gone to two Dog dimensions and tolerances:
One general purpose for everyday practical use - with SpeedKnobs from below where needed
One CT-Dog version dimensioned for the very close tolerances of the ParfGuideSystem and tops made with it.

Hope that helps.

I believe Hans has hit on a key point in the 20mm-fit debate, i.e. that while really very consistent the holes in a stock MFT were not intended to be precise to thousandths of an inch as they were only meant for clamping.  Our ability to use dogs and precisely line up stock & guide rails is just a happy side effect from CNC manufacturing.

As always, I could be all wet.

Hans, can you comment on the fit of either of the dogs in a Fastcap Paulk workbench? The holes are cut by CNC so I'm guessing the "close fit" would work, but would appreciate first hand input if anyone knows!

Thanks!
