MFT dogs with FS cutting guides

[Alan m]

judging by the math s ,id say yes they should. i bought qwas dogs  and they are the same measurement  and fit fine

So far about 10 sets have been claimed, about 1/2 paid/shipped. I am really looking forward to getting some feedback. I have notified anyone I could find a PM from, but I am getting concerned that I may have overlooked some messages. So far these are the only people that (I believe) had expressed interest but I have not reached out to directly.

redbird
Woodworkingnut
John Stevens
RonWen
Kevcoleman
Daniel Doe (2 sets)
WoodWreck
hawhite330

Anyone else on my original list should have received a PM from me.

I am having a real challenge managing the response (my own fault) because I am getting PM's + email at my personal address and the one I set up for this purpose. If you are on this list please send me a PM or email only to ripdogs@live.com and let me know if you are still interested and if so, in what. The options are:

Full set - $100
Knobs/washers = $8
Postage - USA $5
Postage - International $10

Make sure you provide your PayPal account email address and I will send an invoice, this is helps me keep track of things.

Thanks,

RMW

Dont know how I missed this entire thread its massive!!  I must of just kept looking past it thinking it was the old thread a while ago still going on.

I love the friction fit bits which attach to the side of the MFT they look really handy.  I havent gone through this entire thread yet alot to read and catch up I just quickly checked out the videos! I see their has been orders made.   Is their still orders form them bits which slide and fix to the side of the MFT?

I can see them beeing LOADS better than my current MFT set up with the guide rail hinged at the rear and the angle back which you attach!  It makes the MFT much heavier to carry about and awkward so you constantly have to remove them from job to job and then set it up and makes the MFT unable to be close to a wall to save room. So I never bother using it really was waist of money .    RMW set up looks like something I would use not much to carry and I can still use the full size of the MFT by pushing the pins down out the way brilliant! Idea!

JMB - I felt the same way about the hardware that came with the MFT, i.e. it worked okay but it was always in my way when I was not using the MFT for cutting. That is exactly why I started this in the first place. In my current situation I don't have enough room to have the fence protractor sticking off the back of the MFT, it is too close to the wall, as you mentioned this is a common problem.

The dogs are working great for me so far, especially since I figured out how to attach the MFT fence with the flag stop to them. Doing that is as simple as making a small block of wood with one hole to attach to the fence T-slot and another for an M8 knob to screw down into the small dogs. As long as the fence it tight to the dogs it will be perfectly aligned. If I end up making another batch of these I will probably add those blocks to the mix.

I am having an issue with the pins that mount to the MFT rail, even when the mounting block it screwed down tight it is still possible to twist it side-to-side if enough pressure is applied. If the pin is banged into it will tilt slightly to either side and it is just enough to throw off the cut a MM or so. I have not had the time to figure out how to prevent this, I am thinking maybe another t-nut/screw into the t-slot on the bottom of the MFT rail would fix the issue.

Stay tuned, if the feedback is good I will probably make another batch, including those brackets, if I can fix the problem noted above. Thanks for your input.

I have almost no internet access so this is a very delayed report

As I had to come to Thailand before the pin dogs were ready I got 2 sets of "screwed" dogs

With some SS tube and 8mm studding and a few nuts the setup is working well

Ready to cut

I recall you saying you always used 1" sacrificial foam under your cuts. That does pose challenges to using the dogs but it looks like you have worked around them. Glad they still seem to be working out for you.

Without the foam the minimum material width is much less, I suppose only 96mm, the distance center-to-center of 2 MFT holes.

RMW,

Got my set today.  Super fast turnaround;can't wait to use them tomorrow. [big grin]

Those friction slide clamp dogs, and the narrow cut extensions/clips look very cool as well.  Wonder if the fence could be attached to the friction slide clamps, so the flag stop could be used, but still have the full table width to work with? Just a thought.

You have some great ideas!

Thanks,

James

I think there is a bit of a misunderstanding. "minimum material width" is tiny 2mm could be done. My pics are for minimum length. I haven't tried having the dogs on the "off the rail" cut side but will give it a try and report when I can.

I received mine this afternoon.

I have an older MFT (6 yrs old) and the holes are smaller than the pins. So the pins didn't fit. This really wasn't a surprise to me as some of my Festool accessories fit very tightly. So, I took a Microplane round "rasp" and barely cleaned up the holes and now the pins fit fine. It hardly took any time or effort. Any slack will be taken up by the screws from underneath the MFT.

The dogs and the guides seem very well constructed and machined and (now) fit exactly as expected. The guides fit nice and snuggly in the slot on the rails.

I was in the middle of something else but expect to use the dogs tomorrow.

 

[RONWEN]

My MFT's are the new ones and the dogs fit very nicely.  The set is very nicely done and will be a great tool to use.

Quite a long time ago I spent some time figuring what various angles could be achieved using the MFT hole combinations.  As I recall 45 degrees was about the only one that came out even & standard but who's to say with this convenient set some of those other "odd" angles might be useful.
The obvious great purpose of the set will be true 90 degree cuts.

Nice job!  [thumbs up]

 

[moody]

Any progress with those parallel guide rail bracket? Would love a pair of those!

 

[rmwarren]

No however I believe another FOG member may be coming out with a similar product soon which may negate the need for me to pursue it further.

Rookie,

Glad they showed up quickly, looking forward to your feedback on them.

I like your idea of using attaching the fence to the MFT rail/extrusion to get the extra cutting capacity, I have played with a similar idea but my MFT rail is about 0.030" out of parallel with the holes in the MFT over its length. To keep the fence parallel to the holes I would either need to shim it or figure out a way to make the brackets somehow adjustable.

Hope you like the dogs.

Glad they fit your MFT correctly, I was unsure how big of an issue this was going to be.

I agree that the angles available using only the MFT holes are pretty limited. Laying in bed just now unable to sleep (almost 2 AM here) I just came up with a way to use a variation of the little block I posted a while ago to attach the MFT fence to the dogs and also make one end adjustable. Stay tuned.

Thanks,

RMW

Hey - I turned BLUE and became a "Retailer"... (I think "Tinkerer" may be more accuate).  [big grin]

+/- 8 sets have gone unclaimed and I did my best to notify everyone who had expressed interest early on, I will give it a couple more days and then offer whatever is left on a first-come basis. One of the things I underestimated going in was the time that would be consumed in managing orders and shipping, I will probably default to offering the remaining sets on eBay to leverage their selling tools. I won't be able to do this until early next week and will post an update once I have.

I've played with using the frame extrusions also however it seems the precision of the hole grids stops with the hole grids -- it could work to scribe layout lines on the work piece cut line and use that to align to the guide rail.  It doesn't provide for creating a true 90 degree edge as with using locating dogs but would get the job done.

Just wait until Shane starts sending you the Festool commission checks for being a retailer -- you'll be in the "pink" again.   [big grin]

Hey - I turned BLUE ...  [big grin]

What do you mean? Turned blue? I don't see any blue Bosch products in your video.

As far as I can see from those drills/impact drivers you have turned YELLOW [big grin]

Have a nice weekend.

I'll take another set of the unclaimed ones

I need input from one of the mathematically oriented FOG members, I think I stumbled onto the mother of all sine bars. I think, based on my untested understanding of how a sine bar works, you can use 2 dogs to align the MFT fence to any angle just by calculating the sine angle (I am probably mis-stating this) and cutting the proper length of sine block?

These dogs are 24mm diameter and (in this example) 288mm on center (96mm X 3).

[attachthumb=#]

Am I correct that offsetting one end of the fence from the dog by the calculated amount will give an accurate angle, or am I missing something?

Where this is relevant is that I am trying to come up with a simple method to use the dogs with the fence at any angle and this would be a simple solution that anyone could implement without a bunch more hardware. These photos show a simple block in use at one end of the fence that holds it tight to the MFT and dog.

[attachthumb=#]

[attachthumb=#]

I tested this cutting a 45 degree angle and it came out perfect but I want to be able to set any angle.

Little help anybody...  ??? ???
