 I ordered the 36? Incra incremental track http://incra.com/product_jfc_tracks.htm
from a French distributor, which was simpler for me.  This dimension perfectly
fits the MFT 1080 in its long direction, as you can see it in the thread pointed by Steve (Qwas).
My supplier sold me a package made of track and the shop stop which appears on the web page above.

The 52? track could also be used. It was not available from my suppler, but I'm planning to order
it from Woodpecker so I can build a longer similar fence across my two joined MFTs

No problem to install that track on any side of the MFT. You just have  to adjust the base accordingly.

What I like the most in my setup is the guaranteed squaring and the accuracy of course, but
also the handy tool storage it offers. using the holes to insert clamps, caliper, combination
square, pencils, dogs, etc ..  I ended up making  more holes in the base j using the following
hole pattern

                 O   O   O   O  O  O  O          <--- used to register the fence on the table, or tool storage
                    O   O   O   O  O  O            <--  extra holes for tool storage
              -----   incra track ------

 I forgot to say that this is the only track I tried, and it did very well.

The very nice thing about it is that the elongated holes available on the track
 are nicely located and exactly match the MFT side extrusion upper T-track.
(see the pics in my post).

I just had to use longer bolts than those coming the Incra standard
package, since they have to go across both the track and the base.
I reused the Incra provided elongated nuts, shown in the pics.

Thank you for the explanation, did you just use wood screws to hold the Incra track in place on the MDF?
I assume you used a router to cut out the 20 mm holes on the MDF fence support piece.
Why is the 20 mm pvc pipe so hard to get?

I'm planning to make cuts down the long side of my MFT, so my fence will just hang off the left edge...shouldn't be an issue, correct?

How are you planning to get addresses and money from everyone who ordered the 20 mm pvc pipes?

Thanks!

Most of your questions can be answered by reading his thread, MFT guide rail alignment & Incra tracks.

The 20 mm pipe is hard to come by because the USA uses 3/4 inch or 1 inch pipe, not metric.

After the pipe arrives to me, a Private Message will be sent asking for payment. If you pay with PayPal, I will be supplied with the shipping info through PayPal. (PayPal will allow you to pay with a credit card. You will need to have an existing PayPal account for this to work.) If you pay with a personal check or money order, you will need to provide that information to me with your payment.

I'm not sure what I can at the moment. Let me get the pvc here and distributed. If some is left, I will get back with you. I will try my best to see what I can get for you.

I would like to buy about 5 feet.  The specific short lengths and total lengths I will leave up to you to facilitate easy shipping.

Please let me know the total price and methods of payment.

I have been following this thread for  a few weeks now, but since I don t have a MFT I was not much interested.  Just for kicks I was browsing my favorite industrial supplier McMaster.  Guess what McMaster has the 20 mm PVC pipe available.  McMaster p/n is 45435K91 costs $ 10.80 for a 8 foot length.  Dont know if the tolerance on the OD is good enough, but another option for those that have not taken up Steve on his generous offer.

Thanks Vijay.

Nice research there. It's good to know we have a another source. I don't know what they will charge for shipping, or if you can pick it up from their warehouse.

As an update, I'm expecting the pipes to arrive any day this week.

Shipping is usually quite cheap at McMaster.  If your company does any amount of business with McMaster, shipping is overnight and almost free.  Even otherwise they are very reasonable.

When you get your French pipes could you measure the OD and report your results here.  Thanks

 OD = 20.03 mm
 ID  =  17.30 mm

 I filled some of these with foam, so they resist stronger to cross diameter compression,
 for instance when using those pegs to make a reference square
 corner (2 vertical , 2 horizontal) for clamping instead of makingf/using
 the wooden arms as suggested by Jerry Work.

Our pipe has arrived. The OD is 20 mm, .79 inches, or just a hair over 25/32 inch. ID is 17 mm, .66 inches, or just a hair over 21/32 inch. I'm using a caliper so if you want something more exact, use mhch's numbers above.

I will send a PM this afternoon/evening to those who have signed up concerning paying and shipping.

If anyone is looking for items that fit inside of the 20 mm PVC pipe, try "ClosetMaid" closet rod caps, and closet rod connectors. Should be carried in most DIY stores.

I have tried these on some pipe still sitting here. It fits some pipes a little loose and others very tight. Worse case, you might glue them on with some epoxy.

The Caps have an outside diameter of 1 1/4 inches, the Connectors can join 2 pipes.

Hi all,

I ordered two pieces of 20mm from McMaster-Carr early this week.  They came yesterday.  They are marked 20 x 1.9mm but actually measure about 0.2mm larger in diameter than that so are a tight fit in the 20mm holes in my MFTs and MFT3s.  Can't yet say how useful they will be or if the 1.9 wall is stiff enough to use for jigs.  Cost was $10.05 each plus $14 shipping to 97531.  Part number is 45435K91.  More later if and as I get time to do some experimenting.

For some reason sometimes McMaster has 2 part numbers (maybe due to change of suppliers).  The p/n 45435K91 is the same as 45435K1.

Maybe this is what Dave was implying.

In all my years of ordering at McMaster, having one correct p/n or description will result in your getting the right product. You can always call them they are quite efficient.

Also the return policy is very liberal.  Just ship the product back to them with the paperwork that came with the order--they will credit your account.  No RMA, no reason necessary.

Our pipe slides in the holes. I've been testing a few pieces on the holes and there is some variance. Some fit quite snug while others try to slide right through with only their own weight (2 foot long pieces).

Our walls are quite thin also, 1.5 mm, and may be an issue. My earlier post with ClosetMaid connectors should give you the extra strength you might need. A package with 2 connectors is about $3. These connectors slide into the pipe about 1 inch.

It is true that PVC pipes tend to flatten if compressed across their diameter.
There are two ways to deal with this,

 1) Do not compress the pipe directly, but a small MDF rectangle in which the
  pipe is inserted (in a 20mm hole copied from the MFT)  That way, pressure
  is applied in a more uniform way around  the pipe and keeps it circular
  This is the approach used by the home made fence I described.

  2) inject some foam or whatever plastic product to fill the pipe.

      Qwas.    The pound signs were for emphasis, so that people would not buy the wrong stuff.
 
  But Jerry Work proved that at least one person at McMaster-Carr (Jesse) doesn't know his stock.

  So, now that we know the "20mm" pipe is available all we have to do is find a dependable inner

  liner. Perhaps the " closet maid"  will be good looking enough to help.

That did not happen with any of my two MFTs with the same kind of pipes,.
I tried many holes. Now the question is where is the variance, the pipes
or the holes, or both ?

Some quick checking yesterday with the 20mm (nominal) plastic pipe from McMaster-Carr shows that it is too tight a fit in the holes on the MFT or MFT3.  It takes a hammer to insert and lots of cuss words to retract - not the stuff from which jigs to dream about are made.  The 1.9mm wall thickness also seems too soft and will deform easily with just a squeeze from pliers.  That likely makes it too soft for secure positioning as well.  But, and it is a big but, these are just very preliminary observations.

Hey Steve,

Just wanted to say thanks a bunch for doing this for all of us. The order arrived just fine and I promptly "stored" it in the bottom of my tool bag. But yesterday I was cleaning and organizing and I decided to try modifying my MFT3 in a way that PER suggested by side mounting the fence. It allowed me to have the bench closer to the wall which is great in my small shop. The problem was that I lost the ability to mount the second fence support. A quick trip to the miter saw and two 2" 20mm bench dogs were in place and supporting the fence. Thanks, Bill

You're the first one I've known to use the bench dogs with the MFT/3. That's a pretty ingenious use for the dogs! I love it.
