Super Parf dogs.

[woodbrains]

Hello,

Just come across these,
http://www.axminster.co.uk/ujk-technolo ... 1_superdog

Look like they would add increased precision to this set up. They would also solve the problem of dissimilar thicknesses of material letting the track butt up to the parf dogs at a different point due to the collars. Seems like a good development to me.

they do look interesting
and used with the dog rail clips would make a very accurate system
not cheap but I guess machined components never are

I watched it, I have no idea what I watched or what they are for.

Do you really need all that expense to make a square cut?

Am I missing something?

Am I just a luddite?

 

[SteveF]

hi Naz

what do you use to make a square cut?
open to other options
if you have a tracksaw and mft this does make sense IMHO

[NazNomad]

what do you use to make a square cut?

A square, a pencil and a handsaw, in that order.

If it's really thick stuff, I'd use my SCMS

Hello,

This system is for cutting sheet goods in the main. It is an inexpensive substitute for a panel saw, or a portable site solution for high end fitting. It is remarkable that a tracksaw, a bit of MDF and a couple of dogs can enable a craftsman to cut sheet goods veneered MDF etc. That can come close to the precision and accuracy and repeatability of a £10000+ sliding carriage panel saw with scribe. I regularly break down 8 by 4 sheets of cabinet grade veneered boards with accurate, splinter free cuts that require no further work with perhaps 500 quid worth of tracksaw. The parf dogs would increase productivity and accuracy further.

Mike.

do you use the standard parf dogs on your mft?

Looks like another expensive & unnecessary gadget!
Sheet material - use a saw board and hand held circular saw. Costs next to nothing and very accurate. No place for dogs at all.
On my bench I have one dog at the left hand end for planing. It's a 1" square length of hardwood which you hammer up from underneath. If I wanted any more I'd clamp something and/or just wang in a nail, screw, etc. No point in having holes all over your bench and a drawer full of gadgets, just on the offchance!

 

[MikeG.]

I completely agree Jacob. The old school bench I work on has some square dog holes, and I got a couple of steel dogs with it when it was given to me. They've gone rusty with disuse. The holes can be useful, though......somewhere to say drive a nail or screw through a piece of wood without attaching your work to the bench, or drill through something without drilling your work surface. I guess if you have a tail vice you'd need dogs, but I don't. And what's the idea of using a circular saw on your bench all about? That's what saw horses are for.

I’m not entirely sure either of you understand what they’re for.
Still, good job on communicating with smoke signals rather than one of those new-fangled computer gadgets!

 

[MikeG.]

Well what they claimed they are for is aligning sheet material for cutting with a circular saw running on a track. I say that is an inappropriate thing to be doing on a bench, and can be done much cheaper and easier with far less kit. However, if used for the precise location of stock on the bed of a CNC set up, then I can see they might have a point.

Oh, and the little snide comment......leave those out, thanks.

 

[cowfoot]

Fair enough, get in touch with Festool and tell them they’re encouraging people to be inappropriate.

 

[NazNomad]

In the guitarists world, there's a thing called GAS. I can see it might apply to these gadgets too.

Edit: CTAS... more appropriately applied to woodworking tools.

<engage rant>
So the kitchen fitter I worked alongside on a £2 million refit in Highbury was working inappropriately by using an MFT on site?
The (as close at it gets to) perfect 150mm mitres I cut for the base of a cabinet yesterday would have been easier on a traditional workbench? It’d be cheaper, but then again I know a guy in Zambia who can knock up most of the stuff I see posted here for a couple of quid and he makes his own tools. All of them.
That aside, what I don’t understand is the compulsion to butt in to nearly every topic involving new technology with a copy & paste dismissive comment about it being pointless/a waste of money. Now that’s snide - nobody heads over to the hand tools section and starts shouting the odds about it being old fashioned.

What are they for then? You haven't said.
Not all modern gadgets are useless, only 99% of them. :lol:

NB with a saw-board you get the accuracy by setting the board to marks (tape measure etc) and holding with clamps. You don't need a MFT but it would help. You don't need a track saw at all. They are much more accurate than you might think.

 

[MikeG.]

Thanks. That helps with the judgement of who to take notice of around here. It's probably also spoiling the enjoyment of the forum for others, but no, never mind that, rant on........

I use a Festool MFT table and a full size 2440 x 1220 sheet of MRMDF full of 20mm holes that I had done by a guy with a CNC machine. Cutting up all manner of sheet material, including MDF, Plywood, MFC, Corian and sheets of Acrylic, it is spot on square every time. By using these types of dogs, it is so accurate with a Tracksaw & rails and the correct blade for the material being cut.

Throwing sheet material on a couple of sawhorses is fine for rough breaking down of sheets, but if you need the accuracy and clean cuts that I require, the dogs & MFT type top are a real help and time saver.

Dont knock it until you have tried it......!

No, your Mum.

Watch the first few minutes of this to see how they are used.

Below is a real bargain to get you started.

I am currently building a large bench using 3 MFT tops, gives you loads of clamping options also.

You don't have to make the cuts on the bench I do most of mine over the edge so I am not cutting into bench. It's quick and easy to make spot on 90 degree cuts in sheet materials for carcasses etc, much cheaper then a sliding panel saw.

OK for a specialised regular use they could be useful, I see that.
