If only they'd bought out the UJK Parf Guide System earlier!

I needed a work bench that I could slip into the back of my van when working on site. I came up with this that fits on top of a couple of wooden trestles. It’s a bit shy of a full sheet of board but it’s the biggest I could get in my van and slide between the seats. I drilled a grid of 20mm holes in it to take B&D workmate dogs which turns out to be the same size as the UJK system but when I made it they hadn’t brought the Guide System out. I fitted a couple of stiffeners with piano hinges so they would fold flat when the table top is on its edge and couple of jockey wheels so I can easily man handle it and slide it into the back of my van.

I fitted M6 threaded inserts into the ends of my trestles. This allowed me to secure the top to the trestle using M6 male knobs from Axinster Tools.

Table folded flat.

Table slips between the middle row of seats.

I then wanted a way of doing some repeatable cuts with my plunge saw and track guide so I got some 20mm diameter aluminium stock off eBay in 300mm lengths. I then drilled and tapped both ends and fitted Tee bolts in one end and fitted the head of the bolt into the Tee slot on the underside of the guide. With a quick twist the post is locked onto the guide. This allows me to lift the guide up and down and slide under any new material that needs cutting and with a stop clamped at the other end and with B&D dogs along the side I can do repeatable 90° cuts at a fixed length. Because I set the depth of cut just so it cuts into the surface of the work top I don’t get any breakout on the underside of my work piece and also subsequent cuts will always be in exactly the same place.

When the UJK Parf Guide System came out I made a smaller version of my work top one that I could fit to the side of my van and support across a couple of workmates. I use a couple of the longer Veritas Parf dogs to fix the top into one of the movable jaws of the workmate and just resting on top of the other workmate. This allows me still use the jaws of both workmates.

One day I’ll make a new large work top using the UJK Parf Guide System. I’m very impressed with the accuracy of the drilled holes.

Wow, I’m impressed! Well done. It looks like it is something that a manufacturer might well be interested in taking on board for that sector of the trade - that is someone who needs something on which to work when on site other than the traditional trestles.

Thanks David. Any chippy or competent DIY’er could knock this up but next time I’ll definitely using the UJK Parf Guide System to drill the holes.

It’s just made from 18mm outside plywood. I find it invaluable for any project and not only for wood working. Using Axminster or Festool Guide Rail clamps you can clamp your guide track or anything else, anywhere on the surface of the table.


I use these ratchet ones, they are a bit more expensive but they are quick…

The Parf Guide system is incredibly accurate and allows a super accurate matrix of holes to be made in a pretty big sheet of material, but it’s important to use a good quality mdf such as Medite which has a really compact outer ‘skin’.

I agree the better the worktop material the more accurate the cuts will be but to man handle a sheet of medite would be difficult. Compared to the setup I had available to me before working onsite this is luxury. Even the smaller worktop I put across two workmates has far more use and accurate than just working with them without it.

I have varnished the surfaces of the boards to keep moisture out and less susceptible to warping. In fact I’m quite surprised how much the flip down stiffeners keep the big work top flat.

A goog starting point for this type of setup for me is the accurately drilled holes that the Parf Guide System offers. There’s nothing I know of quite like it.

Great stuff Patrick! :+1:
