routing a groove on a fire door for an intumescent strip

[tawraste]

hi,
can you help? i'm looking for a router suited to the task of cutting a groove on a fire door edge so that i can fit an intumescent strip.
i have a plunge router, but it is quite large and i have doubts about the safety of using such a large tool on such a small surface area.
any advice, links or ideas would be gratefully appreciated !
many thanks !

The router should be ok

The only problem is at the start and finish of the cut

To get over this problem cramp a lengh of timber to the edge of the
door so that it overhangs the ends by 200mm, this will stop the router
from dipping on the start and finish of the cut and also give you a wider
surface for the router to sit on

thanks a lot dude,
that's a simple solution, and will save me some bucks.

sorry to put anyone down, a fire door is not a fire door if it's not done by a certified body. even a simple job as putting in a glass panel. once you tamper with the door it's no longer a fire door. be carefull if you need to certify it for councils of landlords. some companys such as merchants and joiners shops may be certified to do this.

So how come i fitted strips to several doors in a very bespoke premise's in london after a visit by the local fire officer ? i also asked their advice on the locks i fitted and followed all their guidelines and they were completely happy with the work carried out ?

Also, you can get a router bit that cuts a 'slot' so the base of the router runs on the face of the door rather than on the edge. £40-50 I think.

To be fair to jp, I guess that's his point - that any changes to a fire door need to be certified according to their guidelines.
