Making an air filter cutout

[owlscastle]

I am sure this has been covered before, but I cant find the answer.

 

What is the best tool to make a filter cutout with in an ally bonnet?

 

Any other tips appreciated, or assistance for that matter, near Horsham ( Beer provided)

If it were me then I would definitely use a dremel, you need close control for obvious reasons. When I fitted my powerspeed 4.2.1 I used a dremel and just took my time plus plenty of masking tape on surrounding areas!!

9" Angle grinder, why pussy foot around with a dremmel, have you not got better things to do with your time ??? 😬

 

 

I used tin snips to finish of and wet and dry paper on a wooden block to smooth around the edges.

2nd for Dremel, worked well for my 4-1 exhaust

Ok, ignoring the angle grinder, what is the best to actually cut the hole before fininshing with the dremmel?

Ok, if speed is what you need then you can always use acetelene gas. 😳

 

Drill some pilot holes first, then a junior hacksaw, use masking tape around the marked edge,

Die grinder, the only professional tool to use. Just make sure you use the correct burrs.

 

If you are in striking distance, drive over and I'll do it for you... if you favour a dremel, ask your dentist to do it for you!

Ok, I used a dremel to cut my exhaust cutout. It works fine if you are careful...HOWEVER, it is easy to slip or have the blade catch and then you run the risk of cutting where you did not intend to. ☹️

 

After this experience I used a pair of aviation tin snips to make the bonnet cut out. This works well and is easy to control. However...the shears leave a small crease in the ali. This is not really a big deal and I have some piping over the edge that covers this.

 

SO, if I was to do either of these again, I'd get a nibbler. There are drill powered ones that folks say work well and there are airpowered versions, but these cost a bit more.

I have one of the hand nibblers similar to http://www.frost.co.uk/item_Detail.asp?productID=8008 . Its ok but can leave the edges of the cut a bit distorted. I'd be inclined to go with the drill powered one instead

Drill holes, rough out with junior hacksaw blade then finish off with flexible drive and flapwheel

One of these here will give a finish which needs next to no dressing.

Mr Locust: Exactly what I have......bl00dy good they are too You'll probably still need to finish it off with a fine file as it's very hard to get perfectly smooth curves straight off.

 

Getting there....

I have a cheapo 'Dremel'. It cost £12 from local supermarket and is very good for such jobs. As previously stated, plenty of masking tape to mark the hole onto and cardboard round the outer area in casethe cutter 'grabs' and sets off on its own. Tight grip. Both hands 😳 😳

 

its only a game.........
