Need to shave off 2 - 3mm off my cooker hood chimney. How?

sjw64 · 30 Jan 2015

Hi

Im trying to squeeze in my new kitchen extractor hood chimney in place but I need to shave off about 2 - 3mm in order for it to fit in.

Does anyone know a way to do this? I have various Dremmel type tools but when a try it leaves a burn mark as it heats up.

See phots

It also wobbles like mad!

Thanks

Is the hood too tight to fit between the cupboards?
I can't really see where you are trying to cut, but would an angle grinder with a 1mm cutting disc help, do you think?
There's always going to be heat generated, I'm afraid.

Or if the material is thin enough, snips like these

You're going to get some distortion though I'd have thought. Don't cut to the very tp of the blades if you do try that way.

Aye, good call Dave.
Wondering if those cupboards could be 'bumped' along!

First thing I thought when I saw the question was that I'd rather mod the cupboards in some way, than cut the stainless. If they can be "bumped" over a bit even better!

I assumed the SS chimney was too tall not that the cupboards were to close together.

You're right.

Even more tricky as it's going to show unless it's cut from the top and some sort of trim put round it.

Thanks for the replys. Yes its the chimney that is too long (top - bottom)

If the chimney was the exact size required, its would slide in on top of the extractor unit and then drop down 2 - 3mm but I just cant slide it in.

Im thinking a file might be the only answer.

Im not too worried about how rough the 'cut' will look as it will be hidden when it drops down 2 - 3mm into the unit.

It sounds easier to lower the hood 5mm than to shave a bit of the chimney.

Eventually the penny dropped

If you can clamp the thing down on your workmate, the slitting disc will work if you can stand the din - and finish off with a file.
I have a similar one.....rather disappointed with the quality of the stainless, and it's a swine to clean (says SWMBO)

I always use an angle grinder then finish with a file (although 2mm I could probably do with a bastard file alone). Dremel doesn't have the power. Work needs decent support, though

You need to lower the hood as suggested, chimneys are usually two part so you can get an exact fit.

Thanks all.

I cant lower the hood at all because its allready below the min requirement from the cooker hob and its all tiled up.

Im going to clamp it down hard and file away later on

Always use an angle grinder for this with slitting disc, tin snip will work but can distort the thin metal.

I had similar problem and was faced with miriad of conflicting innterweb advice on best way to cut stainless steel.

This is a one-shot job with an expensive downside, so in the end I found a local sheet metal fabricators, a small family business, whose palm I crossed with modest amounts of silver (well, paper actually) to do it for me.

'We do these all they time', said Mr X, the proprietor, cheerfully pocketing the agreed sum in cash in exchange for an oustandingdly good job and not troubling me with such encumberances as an invoice!

They did a far better job than I ever could have done wielding a grinder or snips! - the edge was dead straight no distortion or oxide colouring from overheating and they debuured it beautifully smooth! Money well spent!
