Trimming bottom of door

You could probably do it with a multi-tool, working from both sides. Making a neat job of it would take care and skill, though. Far easier to remove the door and use a circular saw.

No.

I have an oak door some 2.25" thick and 36" wide that needs about 5mm

The carpet fitters we used in Norfolk somehow did this but I wasn't there to see how. I asked when I went in to pay the bill but the bugger just said it was their trade secret. I've often wondered how they did it. It was obvious from the undamaged paint on the hinge screws they hadn't taken the door off.

I bet it wasn't 2.25" oak!

This machine:

You can hire a 'Door Trimmer' but at that thickness you may need to attack it from both sides.

Go to about 4:40 to see it being used to trim a ceiling close to the wall. The blade is very close to the edge of the machine and could be used without the rip fence being used in the video.

I'm sure there must be other circular saws with similar capabilities

That door trimming saw is a new one on me, my only concern is that you need a pretty flat and level floor when the door is wide open and the threshold likewise. After years of hand-balling doors to plane them to size my weapo n of choice these days is the router, you do not get the splintering associ ated with saws and a sacrificial timber at the end of the run prevents spli ntering on the edge. Electric planes are fine on the long edges but for me a complete no-no on the top and bottom edges.

Ab solutely not, and if you do take it off be very very careful it does not split. It is also going to be mega heavy and hard work.

Sorry bad experience in my youth! Brian

Maybe they took the floor up then? Otherwise I've never seen it done. Brian

But not the sort of thing you might want to buy for a single door? Brian

Thanks for the replies and the reference to the hire shop. I had a recollection that there was a saw used by carpet fitters.

Yes, Brian, it is a very heavy double glazed door, however having seen the saw and instructions I think I shall take the door off but only with assistance.

Cut the bottom six inches off the door with a jig saw, plane 5mm off it, then glue it back on.

Actually, seriously, I wonder if you could do this with an angle grinder with a very thin wheel fitted. It would make a lot of smoke but it would probably work OK.

Alternatively, how about doing it the way you cut the bottom off door frames when fitting laminate flooring: use a reciprocating saw with a long flexible blade.

Bear in mind that this is an oak door 2.25" thick, and much wider than usual. To take it off its hinges and rehang it will take *many* people. Well, several. Or am I just a wimp? :)

It is going to weigh about 75kgs. That is about the same weight as each leaf of a pair of gates I am likely to need to buy soon. The manufacturers say the weight means it needs a two person delivery.

Agree about planes. For the bottom, a sharp circular saw *with a sawboard* should be OK.
