How to trim 45 degrees edges with MFK 700

[rallye_racer]

Hi Guys,
I'm new to th NFK 700 and was wondering how to trim 45 degrees edges with it.
I have been able to trim one side of the edge (the pointy side) but not the other side.

See picture

How do we need to setup this to do that ?

Thanks !

That is going to be a bit of a challenge, especially with that much overhang. The horizontal base will not allow for that much height or the angled off-set, at least in one go.
You are likely to need a spacer/shim for the base to follow. The next challenge is the follower bearing. The roller itself is there to run along a square edge. Not only will it not follow an angled edge very well, the adjusting knob will probably interfere.
I have gotten around this problem with a hand-made wooden block with a matching angle. The one I made (seen below) is angled the opposite way, but the idea is the same.
As far as the vertical spacer/shim, it could be simply clamped to the surface of the board, or much smaller and adhered to the bottom of the baseplate.

I would likely use the vertical base and trim in several passes.  Alternatively, you could to all the trimming with a file by hand.

On the next one, If you stick the banding on with most of the overhang on the other side, you could skim off the remaining ~1mm from this edge pretty fast & clean with a plane iron, or something flat with a razor edge. 

Which edge shows more when installed?

Great Idea I might try that for sure ! Thanks !

Thing is that the conturo will not allow to have the bigger overhang on the other edge. It guides the lower part of the edge band to be nearly flush with the pointy end. You can't process the part the other way (pointy end up).

The edge that shows the most is the pointy end so it's the one I'm able to do good with the MFK. I might try to trim most of the overhang on the other side with a knife and try the horizontal base to finsh it.

Also important to specify is that we are a large cabinet making business so speed is important.

Thanks you all for the replies. Didn't thought this forum was that active. Nice

Bye, Jason

I routinely trim edge banding with a vibratory sander and 120 grit sandpaper. The final sanding is a few strokes with a block sander held about 30 degree angle.  Sometimes I do it entirely with the sander.

(I do incorporate some hand sanding in almost every job I do.  It makes me feel like a craftsman.)

I’m going to sand the edge anyway, so not an entirely extra step. Th slight angle hides the edge and it also makes it less likely to catch on something and peel off.

It is nearly fool proof (though my random orbital sander is too aggressive for this, yours may be too).
