UJK Parf Guide MKII - What kind of tolerances in the hardware?

[Crazyraceguy]

Mine is the original, I suppose you would call it MKl? Though that name would never exist, without a ll.
I was under the impression that the ll was an improvement? I have never had any issues with the OG.
The original table I made with it was 49" x 97" It is as perfect as anyone could want. I have a pic with one of the TSO MTR squares. You can place that thing anywhere on the table, put dos in every hole, pull it out, flip it over and every dog will go right back in.
I later made a crosscut table, with way fewer holes. It could cut just over 30" across, as perfect as I could measure too.
I don't cut on the assembly table, though that may change now, at home. I might do the removable strip, like the "10-minute workshop" example, since I don't have space for a side table now.

Nice! That's exactly what I want to do.
- 2 holes on Y to position the guide rail on the dogs for the crosscut
- 4-6 holes on X for the fence dogs (or some other kind of fence).
And like yours, the ability to crosscut up to 30, maybe 36 inches.

I was under the impression that the ll was an improvement? I have never had any issues with the OG.

Peter Parfitt has a video comparing the OG to the MK II. The 3mm drill bit changed, along with the shape of the pins. There are also added holes in the rulers for 32 and 48mm offset holes. I don't remember what else changed.

Thanks guys for the feedback!

@edwarmr When I mentioned my pins are snug, I was referring to the shoulder. In order to seat the pins, I have to give a bit of a push and twist. It's a nice friction fit and the rulers are very secure. However, the pins are also snug when pressed into the drilled holes.

With the drill guides, they drop in with no need to twist for them to be seated.

In this video, you can see at 0:34 how he has to press and twist the drill guide into the rulers. I'm guessing that's how @thudchkr guides function.



The green top looks great! Actually, your entire miter station looks really cool.

It’s interesting that your pins are only 0.01mm bigger than your drill guide shoulder but one is tight and one is sloppy. 0.01mm is 0.0004” or 4 ten thousandths of an inch. I believe my parts measure similar to yours but I would have to double check.

And thanks for the kind words on the miter station It was a really fun project. Inside it is a Sys-Port when you open the cabinet doors so it serves multiple functions.

Did you figure out what the issue was? Hardware vs technique.. I received my kit recently and was a little sad that I didn’t have the “snug fit issue” they give tips to overcome. It made me wonder how things would go when I expanded from a small test board to a full size sheet of mdf.

I have the same slop you are showing. I got sent a second set of rulers and it was pretty much the same. I get the slop with the pins and 3mm drill guide as well as the locking pin for the 6, 8, 10 triangle. It is very, very minor movement though. You said the 3mm pins are tight? Is this after you drill the 3mm hole and stick the pin through the ruler into the 3mm hole in your worktop? Because I have found the pins fit super tight in the 3mm hole but the 6mm shoulder where it sits in the ruler has a very small amount of play if I am not placing the pin through the worktop. I’m guessing this small movement is needed so the parts don’t bind.

For what it’s worth my tops turned out good even though I’m not really worried about them being dead square.

That extrusion setup is almost exactly what I'm doing with my setup (haven't gotten the topper yet for some colour).

As to the Parf MkII, my first attempt had some user-error related issues, but subsequent work was all spot on for the table itself.
