gotta love that 80/20 stuff  [tongue]

What's the length?
cut & paste from the Ebay site
One Lot (2pcs) of 80/20 Inc 10 Series 1" x 2" T-Slot Aluminum Extrusions, Part #1020.

The 1020 features one open T-slot on each of the 1" sides and two open T-slots on each of the 2" sides.

Content includes the following:

   1 pc @ 50.7"
   1 pc @ 51.75"
these come up all the time for sale on 80/20 site
I just ordered
2 each 96.5 " 1 x 3 track
2 each 48 "  1 x 3 track
4 each  1x1 48" tracks
for my up coming Ho'made MFT

The shipping is high.
as with other Ebay vendors you put multiples into your cart & they give a estimate of shipping , then you "  Commit to Buy " BUT don't pay them at that moment & ask for a adjusted shipping rate
it is heavy AL products  I ordered about $300.oo in rails & the estimate adjusted the listed  shipping  rate down by 75% ,I committed to buy & asked for a adjusted rate , which should lower some more & save on taxes .
they haven't got back at me yet as I placed it this morning
there is a link on each auction page that takes you to how to buy multiples
here's that link http://stores.ebay.com/8020-Inc-Garage-Sale/BUYING.html
if you want to win a auction & have "buy it now" items as well ,then you just wait till the auction win & it's added to your cart
BUT then pay for everything at once when you done winning auctions & "buy-it-now"
I've been a Ebay seller/buyer for years , so I have experience in how to use the Ebay invoicing system to save on shipping  any questions just PM me
I Am Not a 80/20 employee &/or in any way aligned with them , just a hobbyist  [embarassed]
but back on Topic !
Peter the new  Vid on the planer is Very well done  as all ways  [big grin]
I plan on adding the smaller  Parf dogs from LV to the rails I just bought to make a few drop in fences
this a great thread !
 
Just ordered my Parf dogs and table dogs from Lee Valley, even though I have Qwas dogs and rail dogs.

If I got 1 pair of each, and 4 knobs, the shipping was $8.95.

So I checked to see what the shipping would be if I doubled the order....er...$9.95.

No brainer.

Double order it is.

;)
 
One observation I have about the Parf dogs is that if you are cross-cutting 19mm thick material, the guide rail is not raised quite high enough for the body of the TS55R motor (motor housing) to clear the top of the dogs. I had not anticipated this lack of clearance and was puzzled when the saw met resistance and then tilted over cutting into the splinter guard a mm or so (and the wood also). This does appear to limit the length of cut you can achieve on material of this thickness as you would have to start the cut with the motor housing forward of the top of the Parf dog. You could extend the maximum length of cut by plunging the saw into the end of the stock rather than starting with it already plunged. There are of course other solutions such as placing a board under the one to be cut but that would require Parf dogs rather than short dogs to be used for aligning the stock. Alternatively, the board could be rotated through 90 degrees but that may not be convenient for long boards if the MFT is up against a wall and it would mean a shorter length of the board was used for alignment (as there are fewer holes along the short side of the MFT).

I think it would be good to have different heights of Parf dog so that when cutting thinner (but very common) thicknesses of material such as this 19mm mdf, the saw can pass over the dogs. Alternatively, maybe it would be possible to have a shorter Parf dog with an 8mm threaded hole with extensions that can be inserted when required?

Peter addressed this issue in his video.

I don't follow you.

The video shows cuts with the Parf dogs.

the Parf Dogs can be used to achieve dead accurate crosscuts on the MFT/3 table without the use of the fence. There are other uses but the crosscutting feature sells me on them.

Dave
 
If the Parf Dogs are placed in such that the saw has to pass one or both then a small spacer (parallel narrow strip of wood) is used between the fence and the Parf Dogs to move the saw (and fence) to the right. Ideally the Parf Dogs should be located in the first and 7th rows which not only avoids the use of the parallel spacer but also makes the cut even more accurate.

Peter
 
Peter, I can see how using a spacer between the back of the guide rail and the Parf dogs would solve the problem. When you say "fence" are you meaning the back of the guide rail? (I thought the idea was to avoid having to use a fence).  I was already using holes in rows one and seven but the piece I was cutting was at the limits of what could be cut with this arrangement.

I didn't see this issue being addressed in the video - I watched this one:



I would be grateful if someone could tell me if this was the correct video and where it is mentioned (I skipped over the parts involving trammels and replicating MFTs as I didn't imagine they would cover the basics).

You need to use the low profile dog.

if that is too low then add a short length of 8mm threaded rod and a sleeve.

RMW has dogs that are virtually the same as the short Parf dog. I made a little demonstration of some uses of them about 20months ago

short threaded dog ideas

The quality isn't very good but you can get the general idea. The main point was as a demonstration of using the dogs as a hold-down not a short top post but you can see one at the end of the batten.

I seldom use them as hold-downs and if I did I would use something better than the temporary section of MFT surface the purpose was as an example of what different things can be done with a piece of 8mm studding and a threaded dog. .
 
I have been having problems posting...

To answer Cliff's point I have created 4 diagrams but I cannot upload them at the moment - Shane is helping.

In 95% of cuts (for me) there is no issue with the saw touching the Parf Dogs.

The pictures will demonstrate once I can do the upload.

The new video will cover this in detail.

Peter

Thanks to Shane for sorting out my nonsense with the diagrams.

The first and second diagram show how the saw may hit a Parf Dog depending on depth of cut and exact positioning.

The third diagram shows the setup for 95% of all of the cuts that I do - the Parf Dogs do not get in the way at all.

In the final diagram I show the spacer setup which is what I use for the 5% of other cuts.

Hi Peter & Rob,

Just received my first 4 Parf Dogs (and 4 small dogs), and they're great, in fact (sorry, can't restrain myself) they're "Parfect".

[thanks] Dick
 
Well, I have just received my Parf Dogs and Bench Dogs from Lee Valley - Rob and his team have made an excellent job. They are every bit up to the standard that we would expect under the Veritas name and I am still pinching myself that I have had something to do with all of this.

I am going to go flat out to produce the new video and when it is up I will delete the old one - I am sorry if that produces some missing links here and there.

In the new video you will see how the Parf Dogs can be used to make perfect right angle cuts. You will see them in use with the MFT3, TS55 and guide rail. I will show how those perfect cuts can be made without the MFT3 and even without the guide rail. I will show how you can take a pair of Parf Dogs to a job site and create an impromptu cutting bench for perfect right angled cuts using any circular saw, even without guide rails with no MFT3 in sight.

Peter
 
I received a set of parfdogs this week. Tried them out for a little bit today. Peter would you touch on the use of another board of the same thickness as the piece you are cutting so the guiderail stays flat during the cut, on your video.

Hi Ivan,

Yes, I will.

If there are any other areas that need to be covered just add the requests to this thread - it would help to have these within the next 24 hours (most of the running order has been mapped out). I cannot promise to do everything but I will try.

Hi -

These are now in stock, and available for shipment!

...... Even have orders headed for export (UK and Australia, so far).

Rob

Hi Rob.. Do you have a shipment on its way to a reseller in Australia or is it that individuals have bought some? I am at the stage of spending some money (Birthday money is a wonderful thing) and am wondering if I should order from Canada or if there will be someone a bit closer to purchase from?

I tried doing a quick search to make sure this has not come up in topic to no avail so I am hoping this has not been answered previously.

cheers

Andrew

Hi Andrew -

Carbatec has ordered them, and will be stocking them - so probably best to wait for them to arrive there....

Cheers -

Er.... ya ain't done yet?

[laughing]
 
Peter, do you have a recommendation of what to use as a spacer? Would the MFT/3 fence be suitable? If wood, which type, bearing in mind the tendency of some to warp, be soft or have other issues?
