Parf Dogs

[grbmds]

Hi -

The Parf dogs actually complement the Veritas set. The main difference between the two is that the Veritas MFT set was designed for work-holding, where the Parf dogs (the tall ones) are intended as a complement to track saw (and similar)operations - more about positioning. Certainly the small SS dogs have a lot of functional overlap with the small dogs in the Veritas set.

OK I get that. Would it be safe to say that a combination of the Veritas set plus the tall Parf Dogs would be a good mix? It would seem that 2 tall Parf Dogs with the Veritas set would be sufficient to make the MFT table more flexible and a little easier to square up with the fence and hold work down for assembly, etc.

any chance that some Perf dogs have a opening on top that is threaded for adding jigs ??  

Hi -

The small SS dogs will have an M8 tapped through hole.... The tall Parf dogs just have the tapped hole on the bottom...

Now We/re Talkin'  [eek]

That is a HUGH +  selling point , over other "DoGs" on the market  IMO !
that opens up making a jig that could have 2 dogs attached like on a angle bar OR even some of the 8020 rails that would make for some quick-set-up fences   [tongue]
edit
this makes making side rails on my newly to be designed/made extended type of Ho'made MFT top very easy with these dogs attracted to some 8020 rails

that would be square & parallel to each other ,
opens up endless types of cutting jigs , clamping jigs , low profile router clamping jigs

^^^^ I plan on buying a replacement MFT top & use it as a template jig to make my own long table top that way making the 20mm holes spacing would be exact & precise
Using Peter's process of copying the top one could just walk the jig across a 4 x 8 sheet of MDF & precisely cut all the holes  in minutes .
The MFT tables are just too small for my use .
I'd keep the MFT top as jig over with all my other saved jigs .  
So the Parf dogs are on the next to buy list of mine  ;D

Hi Slappy, one of the things I have on my list to do is to make a slightly larger mobile bench with the MFT pattern of holes done the way you suggest. The holes make jig work, work holding and, of course, sawing using the Parf Dogs, so easy. My bench will be on heavy duty castors, have some storage underneath and be able to support most of an 8x4 sheet if required. At a guess (I have not designed it yet) it might be 800 x 1600 mm (about 2/3 of an 8x4 in each direction.

May be something like this?

Yes , but have the top be able to be taken off & placed on a panel cart for storage , I can't have a stationary table like that , it has to be broke down at times . I'd also run sets of the holes closer to the edges to use them as rail supports with the parf dogs in the edge holes

my suggestion was mainly for Peter as he suggested he needed, wheels hole grid, and storage with a larger area than the MFT. And mine has all those points.

Jerome , your table is VERY nice , Nice job on that  [tongue]

I wish I had that much room to build one like yours , I could use all those drawers for sure !

does anyone ever laminate the tops with something like Formica  ?  ?  Seems that would make the MDF last longer ?  ?

Nice bench Jerome - with some of my new super castors it would fly around the workshop. Please would you empty out all of those odds and ends before you ship it to me !

Cheers.

Can someone point out to me what is the difference between the Parf Dogs and regular bench dogs besides that the Parf ones are taller?  No offense to the inventor, but I watched the video and wonder what am I not getting?

Thanks,
Rob

Thanks for the complement, No problem except you would need to pay the shipping, air package from Thailand and my guess is that it is somewhere about 70kg mark. [jawdrop]

There are some construction pics and detail of the construction at.

FWIW it can be easly be taken apart for transport, and both the boxes of draws have their own wheels for easy movement.

I think that we will see a growth in the building of custom benches as it is easy make some 20mm holes, where needed (and no more), for the dogs and produce perfect right angle cuts every time.

Thanks for the pictures Jerome.

There are a few more on the making of the template I used and a few more items using the 96mm grid.

Template and a few items

Without meaning to hijack the thread...

I've just had an 8' x 4' sheet of MR 18mm MDF cut out by a local CNC company, about 220 holes at 20mm. Whilst I was at it I figured a template might be handy for the future, so taken from someone else's idea I had a half sheet made up with registration holes for 20mm dogs in the four corners (for repetition) and then the rest of the holes spaced correctly using a 30mm hole for my guide bush to conveniently drop straight into allowing the use of a 20mm straight cutter.

£100 all in. Was quite happy with that considering I haven't had to spend any time on it other than dropping the sheets off and picking up after. Looking forward to using the template to sneakily convert my Wife's Ikea step-up (featured in another thread) into a handy clamping stand for use indoors and also to pop some holes into my CT26 custom made top - idea also stolen from another thread.

Getting a top done using a CNC seems to me to be the only way to get complete accuracy. The Festool tops are expensive but accurate. Doing it even with a template seems risky. If any holes aren't exactly drilled right accuracy will suffer. I think we all like the concept of finding a way to create jigs and these Festool tops on our own, but I'll stick with Festool's tops for now. The dogs and clamping kits are a great idea though and, especially the clamping kit would make securement of parts easier and faster, especially for assembly but cutting also.

Lol I can imagine someone sneaking around drill mft holes in any flat surface they can without getting caught.

I myself have been able to accurately duplicate many high tolerance needed templates over onto another board very successfully ,
It's all about getting  solid stable reference points , with a new MFT top & these parf dogs (or any pair of the other threaded dogs bolted from the top then the underside ) as long as there at least two reference points it can be drilled OR use of a good high tolerance trim cut router bit .
I like the trim cut bits (1" deep ones) as the cut is precisely perpendicular to the top surface .  I myself have been very satisfied that I can repeat this all day long on production work , Yes I have to predrill a hole that allows the bit & bearing  to enter but the way it cuts the risk of a plunge bit not staying in reference is gone .
this is where a non-plunge router is useful , I have one Porter Cable 890 router that is it's only function , the use of the trim cut-off bits at just over a $100.oo for the PC on sale it's a no brainer single use tool  , with 3  flute cut-off  bits  , I end up with a very  fine cut surface . I'm not saying this is the best way but I have been able to duplicate a template to where you can't tell which piece is the template when I'm done
Everyone has their own processes that they are comfortable with  & If you feel you can't do as I do that's great go the CNC route .  It's a what works for you is the best method .

Hi -

These are now in stock, and available for shipment!

http://www.leevalley.com/US/wood/page.aspx?p=71185&cat=51&ap=1

Have to give Kudos to our development and manufacturing staff...in fewer than 7 days, we went from initial agreement with Peter, through a re-design phase, Engineering and QC, to stock on the shelf....write-ups, pricing, and web treatment too! Even have orders headed for export (UK and Australia, so far).

We have never come close to being that fast before!

Cheers -

Rob

When you say "trim cut bit" is that the generic name under which they are sold? Are they sold in 20 mm diameter? Will a spiral upcut bit do the same job? I suppose the spiral bit might not be available in that size.
