Parf Dogs

[Claimdude]

Rob,

Any chance Lee Valley will have a presence at the upcoming WoodWorking show in Dallas, TX?

Thanks
Jack

The big brown truck dropped off my Parfs this afternoon -- nice job Peter and Rob!
They will be a nice match with my clamp blocks:

Do those Bessey hold downs need the knob tightened underneath to work?  Or can you get by just dropping them in place?

They do secure the work piece just dropping them into the hole but I wouldn't consider it good regular practice. 
Same when using the Kreg clamps:

Wouldn't continued use like that degrade the hole size after awhile ??  MDF isn't that stable to support repeated/continued stress is it not ?
I felt that's why the laminated tops last longer due to the added support the formica surface added OR is that flawed thinking  ?  ?
If one uses the tops as a cut surface & has kerfs laminates are useless
Just throwing that out there for comment  [huh]

The laminate might help a bit if it was on the bottom of the table as well as the top. The srtess will be on the back of the hole on the top and the front of the hole on the bottom.

I ask as I'm putting together a design for a extended MFT & was thinking of laminating both top/bottom of the surface , this would not be cut into with kerfs as I'd use a sacrificial piece for any cutting 

 

[stvrowe]

Must resist!  Must resist!   [eek] - Resistance is futile.  Ordered a set of these along with the MFT Clamping set.

I agree by only laminating the top then all the damage would just increase on the bottom of the holes .

I'd myself would be in the market for threaded Parf dogs without a collar so one could make a fence that was flush with the top surface ,

to take the Parf even further then Why not the below  ,

even some delirium Parf ones to make some inexpensive dogs that would /could be used in making some sacrificial wood cut rails   , I could then use a nylon bolt in them so not to damage any saw blades .
Just a thought  [cool]

I received the 2 Parf dogs and two small dogs today. They were very nicely packed and are beautifully made (as one would expect from Lee Valley). I tried setting up a cut to see how square the guide rail was to the long edge of the workpiece and it was absolutely perfect! I checked the diameters and they were all 19.90mm. There was a bit of wobble in the dogs which I thought might be an issue with the Parf (ie taller) dogs particularly if thicker wood was being cut so I used the knobs on the clamping elements to tighten them down - this got rid of the wobble completely. I can't imagine there would be any significant error with these dogs as they are machined to such tight tolerances and therefore the pair responsible for alignment in each plane are perfectly matched (indeed all four are perfectly matched). I think the diameters are probably just right as they would be difficult to insert if they were any larger.

I don't recommend importing to the UK as it is too expensive. The dogs themselves are a bargain at 35 dollars (2 Parf, 2 normal) but reasonably quick postage to the UK (3 working days) is another 35 dollars (UPS) and duty and brokerage fees adds a massive £20.65 bringing the total cost in sterling to £65!

I have been in touch with Axminster to find out how much they will charge and they said £17.75 for a pair of Parf dogs and £13.20 for a pair of small dogs - both prices including VAT.  They have now placed their order and expect stock to be available within 6 weeks (this just based on past experience).

I think this represents a bargain.

That is excellent information - I asked Axminster yesterday and they did not know prices - I suspect I was not talking to the right person. Lee Valley did well to get yours to you so soon. I am waiting for mine to arrive and I will then make the new video.

When you are making the new video could you please cover how you would use the parf dogs & guiderail to cut very small pieces - say 50 mm x 50 mm x 6 mm?

At the moment I struggle with the small workpiece moving when the blade starts the cut as the guide rail is not holding it down sufficiently.

Thanks in anticipation.

Charlie

PS Well done on getting your product to market with a reliable manufacturer and retailer.

Hi Charlie

I have been following the 'thin strip' cutting thread and a lot of what I have seen looks dangerous. It is one thing to cut thin strips off a reasonable sized piece of stock but cutting thin pieces from already narrow stock can get a bit hairy. That is one reason many of use a table saw. If I am wrong about what you propose then please put me right and I will include it in the video. I am happy to look at other suggestions for the video  - but nothing naughty !

The new life of the Parf Dog is entirely down to the vision of Rob Lee. He approached me, we exchanged some emails and design ideas and the rest is down to him and his team producing what look to be the definitive design of Parf Dog. I see myself as the Daddy with a small and exciting part at the beginning and plenty of time now to enjoy the creation and many happy reflections along the way. Rob and his team have had the pain, the hard work and taken all of the risks. I am very proud of my small part in all of this.

Just a quick question for Peter and Rob Lee.

I already have Qwas dogs and rail dogs, and I'm about to order a couple of sets of Parf dogs and table dogs, and the knobs, but I'm a bit curious.

On the Parf dogs, has anyone considered flats on one side of the 25mm boss, to provide a consistant surface along the entire height,

for suporting the entire side of thicker stock, rather than just the very bottom edge?

I hope I worded that correctly.

Thanks for those images Ron. I have been trying to figure out how one would attach a fence to the parf dogs. Those knuckle clamps look perfect

 

[Stone Message]

Thanks for that Ron - those fences look outstanding - I am tempted !

do you have a part # for the track?  Is it the Super Track? Will these http://www.festoolproducts.com/Tool-Improvements-Lock-Fence-Dogs-with-8-mm-Thumb-p/lock-fence-dogs-pair.htm work with the track?

 

[Slappy]

this stuff would make a more useful fence & give more options for other uses
cheaper as well

That happens to be the clamp track from my drill press table:

Has anyone found a way of "converting" or probably better worded, modifying the Qwas rail dogs to perform the same function? Surely getting the correct thread and using something bolted into the dog and flipping it upside down? Or am I missing something vital. The more I think about it, the more I probably am missing something vital.

Time to add some stuff to my Axminster cart (when they eventually turn up there (I always wait until I have enough stuff in there for free delivery, sometimes it takes months, sometimes days)).
