Angle grinder on doorframes

[Kathy2]

Hello, we are about to lay engineered wood throughout house. Wood suppliers say to angle grind bottom of doorframes so wood fits snug in rather than trying to cut wood.  Has anyone done this, and any tips on the best way to go about it ie without sparks damaging walls etc.

Hi @proxyau, sorry but I don't think I ever posted the video. I'll try remember to make one next time I do this job.

You really need to use a disc like this. Sorry but I don't think they're available at Bunnings but they'll no doubt have their own brand.

 

First and most important benefit of these is SAFETY as they won't snap like a standard cutting disc. Do NOT use a standard cutting disc.

Beyond that, these solid discs cut cleaner and more efficiently which reduces the heat build up and therefore reduces the impact on the paint on the frame.

Where are you located?

Thanks for the advice! Given we've never actually used an angle grinder before, we were a little concerned about the discs shattering. We'll definitely chase down this disc or see if we can find an equivalent in Bunnings. 

We're located in Lynwood (5 minutes from Carousel shops).

Hello @proxyau

Just to add to the excellent advice given by @ProjectPete you can also use the Flexovit 125mm Diamond Multi Blade. It can be used on a wide variety of surfaces: mild steel, cast iron, timber with nails, plastic, PVC, fibreglass, reinforced concrete and rubber. 

If you need further assistance, please let us know.

Hi ProjectPete.
I read on some sites that metal door frames might be part of the structural integrity of the house in Western Australia.
It does not sound right to me, but was wondering, is there any truth to it, should I worry about anything before undercutting the door frames to install the floor?

Hello @BigB 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your questions regarding your steel door frame.

Let me tag @ProjectPete to make them aware of your question. In regards to your door's structure there could be a number of reasons you have a steel frame. It could be a fire safety requirement in your area. It could also have been a building requirement at the time during the build, then there is also the possibility that it is a structural support for the wall itself. I propose doing a bit of an investigation in regards to the possible reason for a steel frame. 

I suggest starting with the fire safety aspect and checking your local council's rules and regulations regarding door structures, especially if you are are near a fire zone. I then recommend speaking to a builder in regards to the structural support. They should be able to determine if the frame is supporting the wall itself. Your builder should also be able to give you advice in regards to its modification if you are planning on cutting it.

If you need further assistance, please let us know.
