Spotlights

[Jamiemfc]

Good evening

Looking for a few tips on the best way to open out cut outs for spotlights that are already there, got a job on tomorrow and the customers already bought the lights but the fittings theyve bought need a 10mm bigger cut out than the existing spot lights! Any tips greatly appreciated(im sure therell be little gadget out there someone knows of)and before anyone asks yes im a qualified spark just used to a more industrial setting(steelworks)!

Thanks

Jamie

I use a steel rule, in your case line it up 5mm either side of the cut out, make a few marks around the circumferance and then connect the dots. Cut it outwith a padsaw, job done. Thats how i do it anyway, but if there is an easier way i would love to know it

Padsaw was the first thing that came to mind but didnt know if there was perhaps a neater way to do it but if all else fails itll do the job thanks.

If you are quite steady handed with a drill you could use a holesaw on an angle until the hole is started then slowly square it up. Easy to muck up the ceiling this way

I usually use a holesaw within a holesaw, so if you have a 50mm hole and you need a 60mm get a 60mm holesaw and screw a 50mm holesaw inside it for your guide.

or a bloody big cone cutter.

Get a bit of foot square mdf or similiar and drill your appropriate sized hole through it then hold this over the old downlight hole and use as a guide

just make sure you apply ehough pressure on the wood so it doesnt slip and go slow with the drill at first

I like that one mate, that would probably work a treat!

Pad saw. Or if you want it perfect , get a small sheet of wood and cut a stencil with your required hole size. Screw it to the cieling to hold it in place and cut. Repair screw holes later.

Some excellent ideas gents thanks just what i was looking for got 10 to change so might gove all the ideas a try see what works best and feedback my results!

Pad saw, only cut up (as in pushing the blade up) or bits of plaster, paint etc will fly everywhere and ruin your holes

Second this works a treat

To use the two-holesaws method, you need one of these to replace the 'drill bit' arbor. Nice and neat, and works a treat. Loads neater than the padsaw method.

Try it without making the hole bigger. Might be a chance it'll work

I've done this quote a few times. Works well
