Title: Dare I Post by mailee on May 5th, 2004, 1:25am Ok, this will probably start some commotion. I have a set of dado cutters for a saw that uses a 30mm arbour. Does anyone know what saw they would fit?. Ok, yes, I know they are illegal in this country and saws are not made to take them any more but they used to so does anyone know what they might fit? I have a feeling they are from one of the De Walt range of saws but not sure which one? :o |

Title: Re: Dare I Post by WJOHNM on May 5th, 2004, 5:53pm hi there, are you sure your tooling is for a saw?maybe it is from a spindle moulder as 30mm is a standard bore size |

Title: Re: Dare I Post by Dewy on May 5th, 2004, 6:30pm Dado cutters are legal to use providing the table saw has a long enough arbor & has not got a blade brake. This would prevent any saw made in the last few years as all saws must now have blade braking and short arbors. I believe all commercially used table saws had to have brakes by 1st January, making them illegal to use otherwise. This only leaves hobby wodworkers able to use dado cutters if their saw was made before the period when arbors were shortened & brakes includes. Dado blades can be used on a radial arm saw provided it has been made with a long arbor to take them. |

Title: Re: Dare I Post by WJOHNM on May 5th, 2004, 6:37pm hi there dewy, i took it the tooling was for running dado rails is this right? john |

Title: Re: Dare I Post by Dewy on May 5th, 2004, 7:00pm No WJOHNM Stacked dado blades are twin saw blades with chippers in between that allow you to cut dados (housings) in wood at different widths depending on the number of chippers used & the adjustment made to them. You cannot use a saw guard when using them making them unsafe to use. It's DIYers who have used them in the past causing themselves injury that has been responsible for the EU laws on them. Pros have had to stop using them as a result even though they were very useful tools & seldom caused injury because the pros knew better than to be careless with their use. |

I have a DeWalt radial arm saw that I bought about 25 years ago. It is still giving sterling service, one of the best DIY buys I ever invested in. I bought the dado set you refer to - together with a guard which replaces the regular saw guard. I suppose now that I might be using this in a "professional" capacity I am breaking the law? Please note that the dado set is still in the pristine condition it was when I bought it 25 years ago. I never found a use for it. Andrew |

Actually I know a dado head to be a cutter block into which matched pairs of cutters are mounted and held by an allen bolt (a bit like the average planer, but different). Never heard the term raggle head before. Can't remember what the name of my set was when I bought it, but for sure back then there was a dado head for my radial arm saw - and it wasn't this set that I've got! Andrew |

It's an American term. They wouldn't know what a dado is here. The same as they have 'base boards' when we have skirting boards. Same thing. Different countries. They refer to housings as dados & rebates as 'rabbets' Better not tell RR that yanks like cutting rabbets Andrew or he may get worried. ;D;) |

Title: Re: Dare I Post by mailee on May 6th, 2004, 1:19am Ok then a trenching set. I think Handy mac is right it may be for a radial arm saw of which I sold mine, duh!. Well thanks for all the input on it. I have to admit thay are very handy things if used correctly of course. |

Title: Re: Dare I Post by Dewy on May 6th, 2004, 1:59am mailee, a RAS (radial arm saw) is the only machine dado cutters can be used in now. The only other way to produce a trenching cut is with a router & a straight edge. |

Title: Re: Dare I Post by jasonB on May 6th, 2004, 8:00am I have also got an old Dewalt radial arm but would only want to use a dado head (IF i HAD ONE) in cross cut mode for cutting out the waste in halving Joints etc as using a R.A.S. in ripping mode can be very dangerous with a normal blade let alone a dado head. I do have a 150mm wobble saw that I use in my spindle moulder which is great for things like grooves in the styles and rails of shaker type doors or loose tonges, wouldn't be much use for carcase work as you can only get about 30mm from the edge of the timber. Talking of Dewalt, have they taken over Metabo as I saw an advert for their very sexy looking new belt sander which also had a small shot of their "new" random ordit which looked just like a yellow version of my Metabo? ???

Title: Re: Dare I Post by mailee on May 6th, 2004, 9:01am Hi Jason b, I know just what you mean about the radial arm being used for ripping. I had the misfortune to have a peice of timber fly out at a rate of knots on me. and that was even using the anti kickback claws too!. I only ever used it for cross cutting after that. :o Sadly my RAS has gone now and I do miss it but think I shall buy one of the sliding compound mitre saws which should do most of the work that the RAS used to, apart from trenching of course which I now use the router for. |

Title: Re: Dare I Post by johnjin on May 6th, 2004, 9:22am Hi Dewy Quote. You cannot use a saw guard when using them making them unsafe to use. Unquote I see no reason why you can't use a saw guard when using Dado cutters. Surely it just depends on what type of guard you have. Quote. It's DIYers who have used them in the past causing themselves injury that has been responsible for the EU laws on them. Pros have had to stop using them as a result even though they were very useful tools & seldom caused injury because the pros knew better than to be careless with their use. Unquote That seems quite an unfounded attack on the DIYing community. And I would love to know where you get "facts" like that from. If I understand right, you are an amateur woodworker yourself. To try and put the blame for any accidents on to the diy community is a little unfair. If you took the trouble to check these facts I think you will find the opposite is true. As for the EU laws I believe that what happened was the EU brought out regulation to brake saws in a certain amount of time resulting in the loosening of the screw or nut on the end of the arbor. A simple keyed arbor would get around this problem as it does on Milling Machines for example. All the best John |

Title: Re: Dare I Post by Dewy on May 6th, 2004, 3:55pm johnjin, it was not an attack on the DIYers but on the eurocrats who brought the laws in. There are many threads on various forums regarding the use of stacked dado head cutters. My reply was based on a thread some months ago concerning DIYers using tools they are unfamiliar with compared to those in a carpentry shop who have been trained in the safe use of tools and therefore put their own & others safety first. http://www.screwfix.com/talk/thread.jspa?threadID=357&start=0&tstart=0 |
