cutting a staineless steel cooker hood

[Jupiter01]

hi,

I've got a hood which is around 4cm too high. I can't lower it any further as I've got a granite splashback.

a few questions please:
- can I cut the hood to fit as it has two pieces that slot into each other

- it has a few vents at the top and some of these will disappear inside the outer piece once cut and fit. What are these used for and do they have any use when the hood is ducted externally?

- finally how do I cut the hood so it doesn't bend or damage?

thanks in advance

is it sqaure in section ,and can you dispense with the outer and just have the one piece with the "vents". if so clamp it against solid timber and cut with a large hacksaw .use a new blade with the most teeth per inch ( 24 ,or more if you can get one ) cut from the bottom not the end with vents ,as that usually sits behind a raised portion of the hood.

Vents are for recirculation mode.

Use a grinder and SS disc (very thin) for cutting.

I tried using a grinder and it tends to 'blue' the steel so be careful. I used a hacksaw in the end and it was a nightmare to cut. This was the vertical chimney part of the hood.

Tinsnips may work if it's really think stainless.

You're not cutting blocks . Tickle it

Trust me, the hacksaw was a last resort. Problem with some items is they can waft about and there is little to prevent the cutter from slipping initially. There is no easy way unfortunately.

Clamp a a timber guide on

I used a Dremmel with the thin cutting disks. It didn't take too long but watch the cut edge - it's very sharp!

why do I care about the neatness of the cut if t will slide inside the outer piece?

 

[cjard]

If it slides inside the inner piece, why not slide it down 4cm?

If you're saying that, fully slid together the two bits plus the hood are 4cm too high for the gap between splash back and ceiling then sure, cut 4cm off the part of the inner that will be hidden

Next, where your vents are, line everything up, stick a sharpie through the hole in the outer and draw on the inner where it's blocked the hole up, then remove inner and use your grinder to cut a neat rectangle out of the inner that goes around all the holes drawn

As woody said, use a grinder (20 quid) and a thin (2mm) metal cutting disc. It'll go through it like butter, if you go slowly it won't discolour, and in any case it's hidden...

There is no easy way unfortunately.

There are always many ways to do anything, and the easiest possible way to do something is surely "the easy way", no?

There are less difficult ways yes. All are a bit convoluted, so there is no simple or easy way.

It's just not a nice product to have to cut.

if you go slowly it won't discolour

Wanna bet?
I tried cooling and even thought about trying to hold the item on wetted grass.

@cjard you are correct, when slid in together, the unit is 4cm too high. I think you agree that if I cut the inner section, the neatness of the cut isnt do important?

I don't follow your point oj the vents. The vents will mainly fall behind the outer piece with some showing. I though I established from an earlier response that vents are only required for circulation mode. I have a duct which terminates outside.

can you please clarify. Thanks
