The adjustable one might be worth looking into though.

It's like a T shaped metal thing. One bit goes in ur drill. Attached to the two ends of the T are blades, which can be slid along and tightened with an alan key. The hole is cut by the two blades......(Sorry for a rough description but I can't remember what its called).
I got mine on ebay. It was about £10 if I recall.....I'll see if I can find another one

Edit: this is what I mean....http://cgi.ebay.co.uk/ADJUSTABLE-HOL...QQcmdZViewItem

Trapanning tool.

Isn't trepanning what the Neanderthals used to do to each other's skulls??? Apparently still carried out by certain football fans.....

"Trepanation, also known as trephinning or trepanning, is a form of surgery where a hole is drilled or scraped into the skull, leaving the membrane around the brain intact. It addresses health problems that relate to abnormal intracranial pressure."

It's still called a trapanning tool but if it's a squar ehole then I'm an angle grinder kinda guy but it takes a bit of nerve, If you decide to use a Jigsaw then maje sure you cover the sole plate in masjing tape as well cos den dis don't scratch the surface it ain't cutting!

hey easy peasy

does anybody know where I can get a new set of fingers from ?

Right chaps, didn't our man ask about fitting an Icom 421. Its rectangular if I remember.

When I fitted mine I used a hole saw of the correct ish size to cut the corners - rounded.
Then cut the straight bits with a £10 jigsaw from B&Q with a blade for GRP. The blade was almost as much as the saw.
Looks like a steel blade with no teeth with castor sugar stuck to it. "Diamond blade"?
Worked fine.
Finished off with a file and sandpaper

Sounds like a good idea, I'll have a look and see what they have. But Angle Grinder or Jig Saw, seems like diamond blades are the way to go!

Ello all

I used Axminster Tools for my hole cutter. It cost a few quid for the arbour thing which will then fit any of their hole cuttes. They had sizes from about 15mm up to 150mm.
The cutter i bought was a 105mm and it was only about 7 quid.
I hasten to add that these were axminsters own, but through the same company you can get the bosch hole cutters previously talked about so then you can mix and match. Plus you'll only have sizes you need rather than random 17/16ths hole cutters

Yes i know 17/16th's doesn't exist. it was a joke.

What the fek is a 1/16"?

Don't you know Britian's measurement system was metricated close on 40 years ago!?

And none of them cm's either. Metres and millimeters please, unless your measuring fabric products.

Or distances - or speeds or your own weight or.......

Even my kids are being taught to work in cms at school . Metric is so simple and foolproof if used properly.

Here is an example I have just made a kitchen for a customer who said his cooker was 1010 long . Turns out he meant 1100 and couldn't read his tape in MM . Good job I went round and checked in time .

Yeh, the maths and physics departments didn't bother to read the rules at metrication changeover time. And primary teachers....a centimeter is the limit of their accuracy anyway.

Yup. I truly have difficulty using inches nowadays.

Might seem obvious but check that there is nothing behind the hole you are cutting, wires etc
