How to best mortice out a door jamb / frame ... ?

[GrinAndBearIt]

Hey ... just bought a really great bit of kit to help me fit loads of locks - basically a jig that clamps to the door and allows you to use a power drill to rout out a perfectly centred mortice which will accept the lock and face plate.

However ... the jig is too narrow to enable one to then fit it to a door jamb or door frame. I have looked high and low on the internet to see how joiners normally go about the routing on a door frame, and just can't find ANYTHING! Is this some sort of dark secret art? Or is it just a case of drilling out with a wide flat bit, and then chiselling out everything else by hand?

Any tips/ideas/secrets would be very gratefully received ...

wouldve thought within the kit you would have the jig to enable the cutouts on the frames/linings?

look on ebay for lock jigs etc.

or if you can do it ,make up a couple of home made jigs.

you say you can use an ordinary drill, instead of a router?

have you got a link?

you normally use the keep as a guide to chisel out the shape a job not really suited to a jig ??

It does work very well ... but as I say, it can only cope with doors up to 55mm thick.

gregers - I think you're right, I'll have to make my own jig up and use a router rather than the DBB morticer. Just find the whole chisel & mallet thing very time consuming, and love the cleanliness of something routed!

Just use a drill to make mortice and clean up with a chisel, matter of minutes.
Thumb plane helps sink any plates.

Thanks - I'll look at a thumb plane, hadn't heard of that before.

Well - now done three with just drill & chisel - actually, you're right, doesn't take too long, and is quite flexible in a way.
