speak to me like im a 2 yr old
Just getting into the semi-serious routing after owning a cheap ozito router and $60 box of 12 el cheapo bits and have heard people talking about larger bits such as panel bits. Can someone briefly explain for me what these are and are there types of bits that i am unaware of as i thought they were all the same.
Thanks

Hi
Whos a good wickle woodworker then??
Sorry couldnt help that bit.
A panel bit is the bit to make raised panels ( or floating panels ), if you look at the piccy of the desk Im making you will see the raised panels.
The outer, or frame is rail and style, again another bit is required funnily enough called, a rail and style bit.

Follow this link to Carbitool a good source of Australian made bits.
http://www.carbitool.com.au/router.pdf
The file is 3meg so it might take a while to load.
I think I paid something like $ 150 for the rail and style bit, but you only get what you pay for.

WISE, Something that should be made clear is that the larger moulding bits such as the panel bits are inherently dangerous and should only be operated in a variable speed router where the speed can be wound way down.
There is a scale for speeds accordingly applied dependant on the size of the bit.
To work outside these guidelines is invite a dangerous work practice.
100mm wide-or 4" 12,000rpm
75mm or 3" 12,000rpm
63mm or 2.1/2" 16,000rpm
57mm or 2.1/4" 16,000rpm
50mm or 2" 18,000rpm
37mm or 1.1/2" 18,000rpm
32mm or 1.1/4" 18,000rpm
25mm or 1" 24,000rpm
19mm or 3/4" 24,000rpm
16mm or 5/8 24,000rpm
12.7mm or 1/2" 24,000rpm
9.5mm or 3/8" 24,000rpm
6.3mm or 1/4" 24,000rpm
These are only a guidline but you can see the larger bits run at a slower speed due to their size and the peripheral speed of the bit on the outer edge.
There is a vast array of large bits available for all manner of shaping/moulding and are not necessarily cheap but fulfil the task admirably providing that it used in conjunction with a fence and the amount of material is slowly removed in a series of successive passes to arrive at the profile you are aiming for.
Good luck

Get your feet off the furniture.
You are going to bed at 8.00 pm whether you like it or not.
Stop slamming the door.
Having got that off my chest.
If you have access to a Timbecon store, the latest issue of Chatterbox, its in-house newsletter, has a one page article on the use of panel raising bits and some good illustrations of them.
Try www.timbecon.com.au You will find the article there under Chatterbox, together with other articles that have been written.
It only takes one drink to get me loaded. Trouble is, I can't remember if it's the thirteenth or fourteenth.

NO!
oops, that's me speaking like a 2 yr old
You should also look at a few sites like Lee Valley for Router bits - I've found Lee Valley a bit easier to navigate than some of the local ones, and they have the special instruction sheets for the bits on-line.
Anyhoo - they have 'vertical panel raising bits' - these look a bit like a demented carrot, but they don't have the speed restriction. You do need a tall fence tho', as the wood goes past standing on an edge instead of lying on the table. McJing has some too, but you'll have to mine for them.
The extra money you pay for a router bit pays for better quality control as well as better carbide, and the quality control realy counts with bit bits.

Thanks for the info,
unfortunately i'm getting flashbacks to my thumb sucking red wooden spoon marked backside days. (just last week actually)
I tried some of the links provided with no luck, i think i'll go to a local store and have a look at some of the bits, its a little easier to understand when youve got them in your hand. Does anyone know of a good retail supplier near Golden Grove SA or on the North/Eastern side of Adelaide.
What i'm looking for is somewhere with a large cross section of bits in the good quality bracket to get an idea of whats out there. From advice i would rather go quality than pull a piece of bit from my arm with a pair of tweezers.
John,
i posted a thread about two weeks ago to decide whether i required variable speed on a router i wish to purchase, the deafening reply was yes, so i'm saving up for a triton. So the safety issue is reduced, although your recommended speeds will come in useful.(i'm also very cautious with things that can severely damage valued parts of my body)I tell my wife, it's not a lie if i believe it's true

just tried the Lee Valley site and seen a large variety of bits, very interesting. I'm still a little confused as to what classifies a certain bit as being from a particular type or group. Straight bits, edge bits, bearing bits etc are quite obvious, but panel bits seem to be just larger versions of other bits unless they are the types that look like "demented carrots" with two or more cutting points.
Definately going to visit a specialist and see the bits in person. ThanksI tell my wife, it's not a lie if i believe it's true

Forgot to mention:
Carb-i-tool import & distribute their own house brand of bits called 'Econo-Cut' - I have quite a few and find they are just the thing for roughing out ply & MDF - available in 1/4 & 1/2 inch sizes, cost varies locally - they started out around $8 but since the Aus$ has gone up so have the prices :confused: - to around $13 or so. At least you have a good local company doing the quality control & you have someone to ring up if you are unhappy. And at that price who cares if they get blunted or chipped with c**p in the board.

28th June 2004, 09:54 AM #12If it didn't go straight out the other side I reckon you'd be digging around with long nose pliers trying to remove the shrapnel
has anyone actually had any experience with a shattering bit, if so, why did it happen and what were the consequences.
I keep hearing of the dangers, am terrified, but haven't heard of it actually happening!
Cheers,
P

Hi Midge
I had a cheap style and rail set that I bought from Timbecon, that went out of balance one day.
I inspected it with a fine tooth comb but couldnt see the problem. I stopped useing it and chucked it in the bin.
Ages later I did the " big clean " and found this green thing, couldnt work out what it was, then I realised it was a carbide from the style set.
It didnt land all that far from the router table.
I recently bought a big panel bit, this thing is 70mm across and because I didnt have a variable speed router I went and bought the Triton.
When I first used it I tryed it at slow speed but it chattered, so I upped the speed.
Guess what speed it stops chattering at, thats right, flat out.
So now I use it flat stick, a bit scarey but it does it ok. :eek:
Cheers, Al

Only failures I know about is from stupidity. Drongo I was once working with pulled his router off the job still running and went to rest it while re-positioning. The bit hit the metal part of the Record vice and myself and another bloke, who was working nearby spent about half an hour with tweezers trying to extract tiny bits of carbide from various parts of our body. Luckily we were all wearing safety glasses. Seem to get through the metal detector at the airport OK these days. Case hardened bearing housings are the worst thing...but thats another blood letting story...Squizzy

Midge,
I've had a bit lose its TC tip, don't know where it went though. It wasn't overly large but I was doing a few hours of cutting in Jarrah so possibly as it got blunt it overheated and the brazing let go. I've had TC tips fall off masonry drill bits when the hammer action was turned off for drilling through tiles. This overheats the brazing so perhaps the same thing happened with the Jarrah doors.
