Hi

Can anyone describe how you fit cornice in a bay window? 'm having a
serious problem trying to find the correct angles - how is it done?

Internal/external 90 degree corners are fine but the bay is something
like 136 degrees. How do I find the angles?

I could really do with some help on this one.
Thanks

If you cant wait? a metal coat hanger formed into the angle and used as a
template to alter the saw.

Item no 515174 on www.qvcuk.com - £30 + P&P including a "jack xpert saw"

The magicmitre website has comprehensive tips and downloadable
instruction manuals.

I applied coving (can one say 'coved'?) to my bathroom ..
the results weren't bad ... before doing the kitchen I
bought the "Magic Mitre" as demonstrated on QVC ..
I wouldn't be without it ... not many corners are exactly
ninety-degrees but the 'Magic Mitre' makes all mitres
a piece of ...
For joining lengths of coving .. whether it's two or more
metres long .. Magic Mitre recommends scarfing the joints
rather than butt joints .. the scarfed joints are less visible
and easier to smooth down with polyfilla.

and

QVC [1] sells the 'Magic Mitre' box, complete with a jack-saw
that does exactly what you want ... that is transfer an angle
off a wall onto a mitre-box and permit you to cut skirting,
architrave and coving. You can do internal and external corners
with ease ... albeit with a certain head-scratching 'that'll be
an external _right_ so I offer up the work-piece this'a'way'.
The device is manufactured somewhere and huge quantities get
shipped to QVC in batches, these batches tend to get pre-sold.
So get you order in quickly ... see WebPages.
[1] there are other vendors but only QVC include the
(free)jack-saw :) *Remember there is no such thing
as a free lunch!

But does it find the angle of the corner first? :-)

I haven't read all the destructions, but IIRC from watching the demo you
hold the angle apparatus up to the wall and lock it into position, then
take the angle to the cutting bit and cut.

"It" doesn't - "You" (perhaps that should be 'one' for an Earl?) does!

The apparatus includes a plastic hinged angle-finder; this is offered up to
the angle (corner internal/external; banister angle; dado rail; ...
whatever) and pushed against the two defining walls: the angle-thingy is
then locked off and placed over spigots on the arms of the adjustable mitre
box; the mitre box is then locked off - the mitre box has thus been set to
the exact angle required. [Remember the adage; measure twice - cut once].
The angle-of-the-corner isn't so much 'found' as the machine sets the coving
up for an exact meeting/mating joint. { the internal/external settings do
require some head-scratching but the .pdf instruction manual is excellent ].

If a Liverpudlian like me can produce mating coving joints ... then an Earl
(of Derby) should be able to d-i-y his entire mansion ....

Nice retention there, four months...don't you think the coving might be
already measured, cut, installed and painted by now?

Be serious, this is DIY, not GALMI.
