Ugglellama Posted March 17, 2015 Report Share Posted March 17, 2015 I have a bunch of dados to cut for some up coming projects. What would be a good way to find a quality dado stack set that would fit a table saw that currently has 315 x 3.0 blades. I can find 10-12in set in the states but they have at most a 1" arbor hole which won't quite fit a 3.0 cm arbor. Currently in Southwest Germany, but can have people bring it with them from the states as far as shipping goes. I really don't want to have to use the router to cut all of the grooves needed again.

wtnhighlander Posted March 17, 2015 Report Share Posted March 17, 2015 From what I understand, dado blades are not legal to use in most of Europe, for production shops st least. Might be hard or impossible to locate one to fit your saw. Might consider having the 1" arbor hole bored to 3 cm at a machine shop. Quote Link to comment Share on other sites More sharing options...
knotscott Posted March 17, 2015 Report Share Posted March 17, 2015 A router might be your best bet. Quote Link to comment Share on other sites More sharing options...

dwacker Posted March 17, 2015 Report Share Posted March 17, 2015 Pretty much all major manufacturers make 30mm bore dado sets. Check with Forrest to see if they will ship to Germany. Quote Link to comment Share on other sites More sharing options...
Immortan D Posted March 17, 2015 Report Share Posted March 17, 2015 I have a Bosch 10j (European jobsite table saw) here at the workplace and even though the blade (which came with the saw) has a 30mm opening, the arbor is 16mm or 5/8''. There is a bushing for the 30mm blade to sit in the arbor. A 3/8'' width dado should fit there (and maybe also a 1/2''), but I guess extra bushings will be required. I'm posting some pictures of the saw: The 16mm to 30mm bushing: Bushing and 30mm blade: The arbor: A 5/8'' blade in the arbor (this is a skil saw blade), without any bushings, just to demonstrate the fit: Quote Link to comment Share on other sites More sharing options...
Immortan D Posted March 17, 2015 Report Share Posted March 17, 2015 I don't have a dado set to try in this saw, but maybe other members with dado sets can be of assistance based on the pictures I posted. Quote Link to comment Share on other sites More sharing options...
Trip Posted March 17, 2015 Report Share Posted March 17, 2015 I’ve no experience with the Bosch 10j so my experiences are generalized. Usually job site saws lack the power to spin dado stacks… Even a ½” is quite a bit of steel… On the Euro saws that I’ve used, you use purpose-made tablesaw grooving cutters… They are usually available in the standard sheet good sizes and in adjustable insert models… These are 'dado cutters', but the D-word is taboo in the EU, so look for 'grooving cutters'... The thing is, I don’t believe job site arbor diameters and configurations are compatible with grooving cutters --- and I would think using an adapter is a really bad idea… Quote Link to comment Share on other sites More sharing options...
Immortan D Posted March 17, 2015 Report Share Posted March 17, 2015 Power should not be a problem for a 1/2'' dado set since they house a 5hp "peak" motor. The question is: will a dado set like Freud's sit in that arbor? Looking at the pictures I took, I see there's a gap at the left end of the thread, that could be a serious obstacle.

dwacker Posted March 17, 2015 Report Share Posted March 17, 2015 I don't think the OP is talking about a job site saw. If i'm reading it right he uses 315mm blade which is closer to the US equivalent of a 12" saw. 30mm arbor dado sets are very easy to come by as are groovers. Groovers are just not all that popular in the US because dado stacks are much cheaper to get a variety of widths. Groovers are more of a thing for commercial shops that make the same sized grooves day in and day out. I much prefer groovers to dado sets especially with plywood. Groovers and dado blade fall under the same regulation in Europe. Its not the "dado" stack that is the issue its the no guard and riving knife when they are used.

Trip Posted March 17, 2015 Report Share Posted March 17, 2015 Sorry about the jobsite saw, I confabed posts... ==>Its not the "dado" stack that is the issue its the no guard and riving knife when they are used Agree with that... But I can order Felder adjustable grooving cutter for sheet goods --- it's a stock part... I must be missing something.... Are these not sold in the EU? If not, why not just reverse-import them under the radar? Quote Link to comment Share on other sites More sharing options...

If not, why not just reverse-import them under the radar? My guess is they are just like here in the US. They, being the government don't care what hobby people do in their garages. We even have rules regarding dado blades, well sort of but more so saws in general. When running dado stacks or groovers you still have to have a guard.

TerryMcK Posted March 17, 2015 Report Share Posted March 17, 2015 PB and WTN are correct. Though dado blades are not permitted in production shops nobody is bothered what you do in a home shop. Quote Link to comment Share on other sites More sharing options...
Immortan D Posted March 17, 2015 Report Share Posted March 17, 2015 PB I didn't mean to hijack the thread, I just assumed the OP had a similar problem, because when you look at the 10j's technical specs, states that the saw has a 30mm arbor, which is not true.

Trip Posted March 17, 2015 Report Share Posted March 17, 2015 ==>Though dado blades are not permitted in production shops nobody is bothered what you do in a home shop I think I get now, but saying that I get it means that I'm confused by the OP... If the OP can get adjustable grooving cutters for EU arbors in the EU, why bother trying to import a stack? IT can't be a price thing -- the adjustable cutters are pretty close to a Dado King... Unless the OP's trying to save a $100US, then I could almost see the point -- but not really -- the adjustable cutters leave a better cut than a $200 dado stack...

dwacker Posted March 17, 2015 Report Share Posted March 17, 2015 ==> IT can't be a price thing -- the adjustable cutters are pretty close to a Dado King... Probably closer to $600 to $800 for a 16mm set. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted March 17, 2015 Report Share Posted March 17, 2015 But can you actually buy dado stacks or groovers anywhere in Europe? Is it just a continental thing, or does the UK have the same restrictions. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted March 17, 2015 Report Share Posted March 17, 2015 Yes you can buy them from uk Amazon. They are 5/8" bore and most EU table saws come with short stub 30mm diameter arbors. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted March 17, 2015 Report Share Posted March 17, 2015 Although I am aware of some TS with 5/8" arbors with reducing bushes fitted in 30mm bore blades. The problem isn't the diameter of the bore as I have also just found a 30mm bore dado set on Amazon UK http://www.amazon.co.uk/8-inch-Stacked-DADO-HEAD/dp/B00FIPAE3U. The actual problem is the short stub length of the arbor that won't let anything wider than 1/8" onto the arbor. You can of course have a long stub made at your local machine shop.

Trip Posted March 17, 2015 Report Share Posted March 17, 2015 $600-$800 -- Wow... I had a leitz 'thrown-in', which is an OK, but not a top whack cutter... Quote Link to comment Share on other sites More sharing options...

Ya scoring type cutters are expensive but they outperform standard blades in every way. You can get thick kerf blades for much less but they are not much good in plywood. Dados and rabbets from scoring cutters are much nicer than anything you can get with carbide tips or even router bits. Quote Link to comment Share on other sites More sharing options...
