I need to mortise out a door to accept a Baldwin mortise lock.
I know that the tolerances are really tight (with errors being pretty
disasterous) and that locksmiths typically use a router with a fancy
mortising jig.

However, I have not been able to find the jig in the local tool rental
shops, so I was wondering whether there are any reliable alternative
approaches or sources for a good jig?

Thanks

I've always just done them by hand with a chisel and then drill out the hole
for the bolt. If you're bent on using a router (which makes sense if
you've got a bunch to do), there are templates available but you can easily
make one with a small piece of ply. Just cut the template taking into
account the bearing on your router and voila! you've got a template.
Cheers,
