>>938798 the regulations have specified that spinning blades must come to a full and complete stop within 10 seconds of the power to the blade being shut off if the blade is readily accessible to the operator's body.
Large fab shops and equipment used industrially have retractable blade guards, or heavier duty engine brakes to comply with the regulations.
>>938798 This is illegal? Maybe in a civilised country. I live in Europe and I use them, don't have any special permit for them, just had to look for them a bit longer since the local shop didn't carry them
In Germany every professional has to be a member of the Berufsgenossenschaft (BG). The BG provides insurance for work related accidents, but demands that all members adhere to strict safety standards, such as only using BG certified tools and techniques.
Dado blades are not BG certified and as such no professional woodworker uses them to build stuff. A Private person can use any tool they want, but because there is no professional market for not certified tools, dado blades are scarce and expensive.
You can get dado blades and use dado blades in the UK. They just don't sell contractor saws with arbors suited to their use so you have to either fuck with it yourself or get cabinet saw suited to their use.
>>938892 but then how do they cut grooves and dadoes in a production environment? dado blades exist because they're fast and easy. do they all just use chisel and router plane, or do lots of passes on a regular table saw blade?
>>938970 I made some simple crosses with a carpenter buddie of mine, he made the dados by making two cuts left and right and then slid the piece from side to side between the two cuts, slowly moving forward after each pass.
I'm not sure if that's BG certified in case of a fuck up.
>>938963 Not as fast or as easy as a router. This might be open to opinion and interpretation but I really don't think setting up a dado stack perfectly is as quick as using router and set size cutter.
>>938999 I don't use the dado stack unless I have to batch out many odd-shaped dados. But the advantage is, you only have to fiddle and experiment with the shims once. Once you confirm the width of the dado with calipers, you write down the shims used. The blade itself is a monstrously efficient cutting machine, and something about it....the eery silence when it spins, and how my particular set channels 100% of dust into my dust collector (more so than any cutting tool I've seen) makes it so much fun to use. Shame you guys don't have these.
But yes putting in the stack itself is a pain in the ass and I always fear banging the carbides together and and ruining my investment, so in practice I just use a router table.
Europe is pretty small and each country is like a state in the USA. A lot of places simply don't have trees that are being timbered. Most everything is imported and expensive. Woodworking is a highly regulated trade skill.
Asking about wood working tools in Europe is like asking about snow plows in Florida.
>>938963 In Europe the ol' wobble blade is more common than dados. Its basically a single table saw blade that mounts at an angle. It doesn't go as fast as a dado and it leaves a concave bottom but it meats all the regulations.
>>939219 PowerShop 1400? Mah brothah. I've got one too. Came with the factory cabinet and a ton of blades. Got in on CL for free because the power switch was broken (dude thought it was a blown motor) and left it for the next tenant to deal with. New tenant didn't want it so he gave it up for free.
>>939223 Aww, thought it might've been cause someone cut their arm off or something. >>939225 It's a 1511 actually! Damn good job getting it for free though brah. I got mine for 81 bucks, just picked it up yesterday and rebuilt the cabinets over the fridge in my new house already. Had to raise them for when I replace the disgusting carpet in the kitchen with hardwood cause I had a grand total of an 1/8 of an inch.
I also got pic related, 3 finish blades, and a bunch of pipe clamps for 20 bucks.
Have you built a table for yours? My only complaint is the tables pretty out of whack now, puts a little bezel on everything I cut, not huge though.
>>939242 Radial arm saws are tricky to get zeroed in. DeWalts are good though. Once zeroed in they hold it very well. Craftsman brand RAS of the era and later were basically garbage and gave the radial arm saw a bad name. Check out vintagemachinery.org and dig up a manual for your machine. It will have instructions on how to get it zeroed in properly.
This picture is from vintage machinery. Its a Powershop 1400 with the same setup as mine. It seems the 1400 was the model that followed the 1511 in the mid 1960s.
