Any tricks for aligning kapex miter cuts?

[agehall]

I went out and got myself a Kapex 120EB last weekend as I was tired of my old Bosch PCM8s which never cut exact. Quite an upgrade, but well worth it.

Now I face a rather annoying problem when I try to cut new pieces that should fit the old ones that were cut with the Bosch saw. Quite a few are 45.x degrees and I find it difficult to align the Kapex exactly to these cuts. When I try to lock the angle by pushing the lever down, the base often moves just a tiny bit and sticks to 45.0 degrees instead.

Are there any tricks for aligning to angles close the fixed ones?

i think there is a detent over ride on the kapex.
if that wont wont you could cut a wedge shape and use that to move the cut away from the detent

I thought the detent lock lever has a half way down lock which locks it between detents?

I have no problems locking the miterscale of my kapex very close to detents, even without holding the detentoverride (the little springloaded lever above the the miterlock lever), maybe holding the springloaded lever fully pressed until the bigger lever is fully locked down would help. (again, on my kapex there's no need for this, I only use the small lever to get it out of a detent-position).
Or maybe there's a problem with the miterlock on your kapex, and it doesn't lock down tight enough for it not to slide into a detent after it's locked down.

Are you holding the thumb button down until the big lever is locked all the way down?

There should be no impetus to find a detent if the thumb button is depressed.

Maybe I'm releasing the small leaver a little. I'll have to play with it some more, but I do find it a bit tricky to handle both of them at the same time, so that could be the cause of my problems. Practice should solve that problem.

Can you use your mating piece as a guide.  Align the mitered edge on the Kapex fence then use the long edge as your fence, set the saw to 90º and then the miters will be perfect.  Of course that is on dependent on how accurately you get the miter aligned.  I've never done this but it works in my head.
