Yep that video is a bad exemplar as the rail has to be suspended, but as I said the topic pic was taken with rail completely flat on the work surface and it still cut like that.
Another small example here, again the rail isn’t fully supported by stock but do have another piece further down (this is the one I measured with calipers above). I just don’t have thick and wide pieces of lumber to test with unfortunately.
Just had a quick look at the two videos you posted - this is the sort of setup I would do if I needed to do a rough cut and couldn't be bothered to get the proper tool for the job. I hear what you're saying that even when the rail is fully supported it does the same thing, but a video of that would be good... because what you've shown is a 14cm rail which has two non-slip strips - being supported by the first 2cm or so of the rail with just one non-slip strip touching the wood - I'd expect rough cuts using the saw like that.
The MT55 is a panel saw... if you can't get the rail completely on the material - you are already out of the limits of what it was designed for. Don't get me wrong, I do the same sort of thing sometimes - maybe forgotten to bring the right tool to the job, etc., but seeing the rail flexing around on two after-market posts with just the edge of the rail hanging on to the wood for dear life... well put it this way - the cuts aren't too bad considering!
with regards to raising rails with dogs… I suppose any twist in table top from an uneven floor, diy hand drilled mft holes (not this situation) etc. will only exaggerate any dog angles (between each other, above plane) the higher the rail is stilted, which transfers twist to bolted rail.
Ok got saw back at weekend. They couldn't find anything wrong with it, except to say that with the 52 tooth blade they did see some angling of cuts when doing rip cuts, but not with the 32 blade they recommended.
I immediately cut some 30mm wood and it was straight so was pleased. But yesterday cut my good 25mm oak stock I had been planning to make into a panel, and later on noticed many cuts that were angular.
I am beginning to conclude based on comments here that the saw was not as forgiving with cuts as I had believed it to be, likely as most of my cuts were on quite thin, wide stock. Also the oak I was cutting was warping, and I was not able to clamp it down fully so that may have contributed to the errors.
Additionally I had some confusion over the guide dogs. When I first got them I used them horizontally (as in, both horizontal to each other in the left and right under slot) and after the accident this no longer worked, the bolt lookedf slightly bent. However new bolts didn't help, and I am now thinking that I actually forced these guides in as the distance between rails is further than the 96mm of the holes.
So I was trying to alter between horizontal positional further along (which can skew rail I now see) and vertical placement festool style, which isn't really as good as rail can more easily tip to one side. Anyway this is latest setup pic for cut, this is my only good saw as well.
Take a piece of paper and line it up with each edge of your work bench on the photo on your screen... it's straight, now do the same with the rail - it's not straight. I checked this as I could see a great bulge in the rail...
Your rail needs to be flat, you can't hope to get a perfect cut with a less than perfect set up.
Asides from that major point... you are over complicating your setup.
Let's say you have some 75mm x 25mm wood you want to rip... lay 2 next to each other and the rail will neatly lay on top of them. It's 50mm wide?.. put 3x next to each other and you will have proper support for the rail... the wood's not even or the same thickness?.. run it through a thicknesser - you can't expect the rail to sit correctly on uneven wood.
Try working on your technique - get the rail flat and stop messing around with dogs!.. you will thank yourself in the long run if ever you need to do a 45 degree rip with a setup like that. Feel free to ask if you have any questions.
Thanks for tips, have been getting some more clamps as well. Also might get some quick release rail clamps like these I posted in another thread as sometimes too lazy to bother with Mafell due to screw head:
abdon: I stand corrected , the angle fence is only attaches with F -Tracks , what confused me was , that the Timberwolf site mentioned it will work with the NFU machine, yes it will work but only I guess when you use the Ftrack , with other tracks Like the KSS L.

glynnco: Did you order from GereedschapPro? I see them as in stock but I'm located in the US and am not sure if they ship here. I sent them an email asking about shipping but it was returned undeliverable...

jonathan: I've purchased a lot of stuff from our neighbours @ GereedschapPro.nl As far as I know they are one of the larger Mafell dealers in the EU. I can recommend them, they usually respond quickly.

lasse: Thanks for the tip! I have own a mafell rail which is 160 cm and one that is 80 cm. Will it work just as well or will I need to buy rail that is 110 cm?
