You can also get commercial jigs with inserts for different standard
hinge sizes.

I had a go with one of these once

http://www.rockler.com/product.cfm?p...er=hinge%20jig

although didn't buy it . It did work quite well though and was quick
to set up. especially if one wanted to repeat on several doors.

I think that there is some value in these jigs for people who have
difficulty using a chisel, although I think that the set up time might
be better invested practicing cutting hinge recesses in scrap material.

Looks like another completely unnecessary bit of kit which
the likes of Axminster and co hope to sell to gullible amateurs -
which applies to about 90% of their catalogue (and every other
catalogue more or less)

Some bits of kit actually make the job harder and screw up your chance
of ever learning how to do it properly (or easily) - chief amongst
these being the honing jig/guide.
