An Improvement To An MFT Fence System And Hinged Guide Rail Front Pin!

- I knew when I received it that it'd only be a matter of time before the Benchdogs UK under rail support fence got bent. A slight 9x20mm protrusion from the fence proper, on my version, it was attached via connecting bar. Although these under rail pieces are now machined as a one piece, I still think it'd be a weak point. My fence doesn't stay on the bench. It gets stowed when not in use and so more likely to suffer the odd ding.
This is exactly what happened to mine recently, bending my under rail piece slightly. Nearly ruined a whole bunch of drawer bottoms, though thankfully, they were only for me, not a client.
In this video then, I go about making the under rail fence stronger. Plus, as a needs must to maintain cut capacity, I redesigned the front pin for my hinged guide rail too.
Hope you find something to interest you in this vid.

Very well thought out solution mate. Perhaps you should contact benchdogs UK and talk to them about it??
Id ;ove a mafell saw but here in the states, they're twice the price of a fezzy. I prefer their design and rail system but as I only do woodworking part time, I can't justify the expediture.
Thanks mate. Wow. Didn't realise there was quite that much difference in price re Festool and Mafell in the States! I guess it comes down to volume? Mafell being tiny. Thing I actually love most about the Mafell is the ease of blade change, it's micro adjust functions and that it's almost dustless.
Very innovative work as always
Cheers mate👍
Neat solution, definitely a big improvement on the existing rail, but an expensive way of getting there. Might be better to just buy oozenest extrusion and make your own.
I like the way you’ve got 600mm cutting depth on your MFT, the reduced cutting depth is one issue I have with my benchdogs rail. I plan to affix mine to the back of the MFT to give me the wider cut capacity but need to think how I can make it micro-forward/back adjustable along its length to allow for inevitable lack of squareness there will be if I just clamp it straight on.
Cheers. Yeah, i mention briefly at the end you could save a few quid buying your own profile. The fence dogs are neat though. But as I already had the the fence, i worked with that. Always the tricky bit when building your own system is adding in micro adjustment. Good luck though. Worth having a go at, bespoke for your needs/space👍
👍👍 👍. Thank you
Cheers mate 👍
The under-rail support is definitely the weak link in the fence system. I've been using a length of 20/20 and 2 joining brackets (all Ooznest) and it is pretty robust but 20mm is really to high for most sheet goods- the guide rail can't grip the workpiece! For my use I would ideally have a 9mm high under rail support but then I'd need a way to attach to my 40/20 profile that also gives some accuracy. there are very few videos about this so thank you for posting. I'll need to have a think about how I might adapt your solution to fit.
Yeah, that's the problem: trying to keep the under rail low profile. Laying flat and cutting down one end if the 2040 I found the neatest solution, ensuring a perfectly inline fence and 7nder rail. Does mean you have to be prepared to sacrifice a length of profile of it goes wrong but it's quite easy.👍
In Australia we have 2010 (if using 20 series) and 4016 (if using 40 series like yourself) extrusions. One side is solid+flat and the other has the t-slot. If you flip it so the the t-slot is facing down, you can use a joining piece to connect your 4020 to the 4016. The joining piece can be cut to a custom length from my aluminum guy so making it 400mm for example *should* provide enough stiffness. It still leaves it 16mm high though. Using the 20 series would be much easier as that's only 10mm high. I'm guessing routing a 7mm channel in your mft top is out of the question? That'll drop the 16mm down to 9mm from the worktop.
@@feechl that’s a great idea. I did think about a piece of t track but not using it upside down. I can’t help thinking though that it would need quite a long connector bar to stop/ reduce lateral flex?
@@johnparker2636 Remember you can run the connecting bar the entire length of the 4016 piece (I'm guessing roughly 200mm for most people) then the entire length of the 4040 piece if you could get a bar long enough! I think 200mm each side would do or 300-400mm on the 4040 fence side if you wanted to be safe. Remember with your 4040 you have two t-slots so you can use a connector in both. Also, if you find it flexing you might be able to wrap something around the connector bar to stiffen it up (maybe).
@@feechl I didn't know you could get longer connecting bars for 20 profile - thats good to know. Appreciate your advice on this- thanks
I have the same Benchdogs fence system with the under rail support being attached with a connecting bar and ran into exactly the system problem this is a major design flaw and cost me an absolute fortune in wood and ruined projects tying to track down the issue before i eventually found it not to mention the hours of frustration. I also find it hard to believe that the new system that is all one extrusion is any better given how narrow the under rail support is. Great video i may implement the same as i haven't used the Benchdogs fence system since i found the issue.
Sorry to hear that mate. Thought I treated mine with kid gloves but one knock is all it took. I'm more confident it'll hold up as it is now though 👍
