Square cut window for fillets

I currently mark up the back of the mount board and use the wall mounted board cutter to make the cuts by eye. I find it easier to see the start/stop lines with the wall cutter than with the non-bevel blade on the mount cutter.

What do others do?

Can't you just do a reverse bevel?

I cut a reverse bevel, looks better and allows for a bit of adjustment.

That does not sound like an easy way to do it. Doesn't your mountcutter have stops for start and finish of cut?

Even if it does it's not so easy for the 90 degree blade and nor is the use of the margin guide/squaring arm. Maybe Chris thinks a 90 degree cut is best for mount fillets, I don't think it is because just the slightest bit of play will reveal the core of the board, reverse bevel is the way to go .... unless you like the look of a normal bevel, some do.

I cut a bevel with the sheet faced down on the CMC. On my machine it seems to be better than doing a reverse bevel but that may just be the way it is set up.

On our machine the reverse bevel is as good as the normal bevel and in fact if we are cutting volume mounts in black, we always cut with the board upside down to avoid curling. Only happens on black though.

For fillets we use straight cut and have no problems, although I can see an advantage in reverse bevel as Robo says, to get a tighter fillet up to the board.

I agree cutting with a reverse would be better for cutting black. The only reason why mine doesn't cut well on the reverse bevels is that over the years i have adjusted the settings only for the cuts i use and not for the reverse bevel as i never use it. :giggle:

we just do it reverse bevel cut from the front as well. seems the simplest and tidiest finish as robo says above.
I haven't actually bothered calibrating anything to cut from the back on this one.
they are usually one-offs and not overly in demand here.

on white boards they look pretty good with an ordinary bevel, a matter of taste I suppose. Customers never botherd when we used to do them that way round. personally I'd prefer the look of not seeing the bevel if I was a customer and given the choice seeing one next to the other.

People seem to be asking for them a bit more than they used to, so I suppose its worth keeping in practice with them. One of my lads has got very good at doing them (obviously the youngest one with the best eyes, as me and tom actually read (see) the morso scale a mm different each way :-/ ) Might be time for one of Keith's gadgets if we get enough in regularly...
