Introducing the UJK Parf Fence - a must for MFT3 or custom benches

[fritter63]

@ Peter,

I just went to see about ordering a UJK fence from TSO, and they list it as "This product is no longer available online. Unfortunately we are unlikely to receive any more stock."

I'm unable to find it online anywhere else. What's the deal? Do have another link where I can purchase it?

Thanks.

Axminster are showing it as unlikely to be manufactured any more.

I bought two a while ago, and to be honest they aren't worth the price. (They were also poorly finished)

Two dogs and a straight edge achieve the same effect for very little cost.

Hi Everyone

When I created the Parf family of products I assumed that they would be used together and not with products from other manufacturers. Axminster have had about 3 or 4  instances where the Parf Fences have not fitted the tops produced by other manufacturers - the Festool MFT3 is a good example. So, manufacturing was stopped and a new product will be released very soon. Existing users of the original Parf Fence will not be at a disadvantage but owners of 3rd party tops that have not been created to the accuracy that should be achieved using the PGS will be able to buy a product to suit their needs.

I have no more information right now and will make sure that I post a thread on the FOG as soon as I can.

Thanks for responding quickly and clarifying that Peter. I have the fence that a friend of mine purchased recently and it looks very high quality to me. I look forward to seeing your new offering.

I'm about to CNC a custom Vario style top for him to use it on. I may just give it a try making one out of some leftover Corian while I wait!

Well that was short lived.

All you need is one or two round (anchor) holes and one elongated hole on the opposite end. This will accommodate various grid sizes or discrepancies. I personally prefer 100x100 mm grid.

Well, I FINALLY got the CNC finished (had my hands full expanding it to be 4 x 12.5 feet long!). It's now square, level and trammed. So here was my first test run at boring 20mm holes with the Festool bit from the LR32 kit, and then chamfering with a standard 45 degree bit.

I found that the UJK fence fits perfectly in the CNC laid out holes (96mm on center).

Tomorrow I'll make the full sized Vario inspired table top (36" x 72") - apologies for mixing my measurement systems. I usually program in metric, but my friend specified the dimensions in imperial.

Will start a new thread under projects when this is done

Just FYI, for anyone that was interested in these and then disappointed when they were pulled: Axminster has the updated version available now.

It is always interesting to see a 'young' product evolve thru the generations of updates. Too bad nowadays a lot of products depend on cosmetic changes instead of innovations.

I have been eying the UJK FENCE AND LENGTH STOP FOR GUIDE RAIL SAWS 107068 but at present it is out of stock at Axminster. It looks like a good fence and reasonably priced. Does anyone here have one? Since the dogs are adjustable along the fence it could be used along the 45 degree line of holes too and even the 60 and 30. Unless anyone can find fault with this unit my intention is to purchase one when it comes back in stock.

I received my Parf Guide this week and am very happy with its quality and both rule hole alignments are dead on when laid atop one another. Right now where i live there is a shortage of 3/4 MDF so i am waiting for stock replacement.

But I'll agree to disagree on the math.  1 megabyte is 1,000,000kb.

You can disagree with the math, but you would still be wrong.  One megabyte is 1,000kB, where "kB" is kilobyte, or one thousand bytes.  One gigabyte is 1,000,000kB.

Correction: A megabyte is 1,024kB

Wikipedia:

The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix mega is a multiplier of 1000000 (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities.

However, in the computer and information technology fields, two other definitions are used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as 1048576 bytes (220 B), a measurement that conveniently expresses the binary multiples inherent in digital computer memory architectures. However, most standards bodies have deprecated this usage in favor of a set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB).

Thirty years ago, the working definition of a megabyte was 1024 kilobytes, which were each 1024 bytes. When it was officially standardized in 2009, they chose to use the metric denominations instead for consistency with other units, and created the "kibibyte" and "mebibyte" to refer to the old definition based on powers of two. Bit of a jarring change for those of us who were working with computers in the 80s and 90s, when the powers-of-two definition was the common one, and it's why there's still so much confusion around it today.

I noticed Axminster now have the 1000mm long fences. I like the idea of a longer fence or two shorter fences especially with the stops.

I was considering getting the benchdogs uk fence as it has the measurement scale on it. Do users of the parf fence find measuring with a tape etc then lining up the cut accurate enough?

Cheers

I ended up ordering the parf fence (600mm) and it arrived yesterday. Can someone please confirm whether the middle dog hole and one side of the fence have elongated dog holes as per the picture below.

I’ve checked photos online and they seem to have just the standard 20mm holes.

Thanks

 

[hdv]

Yes, this is as intended. To quote Axminster/UJK:

The fence features three sets of holes along its length. Each set comprises 4 chamfered holes (to ensure the dogs sit flush with the top). The first set of holes are a precise 20mm; the others are fractionally oval to overcome any minor variations in the bench top.

Seehttps://www.axminstertools.com/ujk-parf-system-fence-stop-kit-1-000mm-107462

I think I saw a recent video by Peter Parfitt explaining the reasoning behind it. But in essence it is to allow for differences in the spacing of the dog holes arising from different production processes.

Hi [member=66485]hdv[/member]

Yes, it is to allow for cutting stations and MFT3 tops that are not created with the Parf Guide System (PGS). The PGS gives a very accurate layout of holes but many CNC produced tops can be a dash off. The very worst tops are created with small jigs which have to be used many times across the length and depth of the top and the accumulated error produces dreadful results.

Makes sense thanks for the replies
