You don't usually need threadlock, though I have used it in the past when securing a loose stud into a wire coil repair. Just make sure after it's cured you remove every trace of liquid threadlock from the coil or you'll threadlock the bolt into the coil when you install it. That stuff doesn't...
Other way round. A slower wheel is more open and cooler cutting/faster wearing than the same wheel turned faster.
ID wheels are spun fast to keep the sfm up and avoid excessive wear/give a better finish.
I'd consult an expert. You cannot put a pressure washer anywhere near my house as the bricks are too soft, it does nothing initially then gouges the surface.
Get some quotes from professionals and that will give you a good idea of what process can and cannot be used.
Except when set screw is used as an alternative way to describe grub screw.
There's a lot of truth in this. I would not ever take a M20 fully threaded construction steel fastener and call it a screw. Similarly I would not take a parallel-shank shouldered threaded fastener for screwing plastic...
The metallurgy of aluminium can change dramatically through welding. Several times I have had a piece of perfectly machinable ally, done some welding on it then tried to machine it afterwards and it was all but impossible to work with. Went from nice chips/swarf to horrid gummy metal which tore...
I have my clamp on the end of the bench and just sit work on the bench itself but you do get the odd arc burn especially if the part is sitting on a narrow corner or something with minimal contact. For the most part it makes no odds but if your work needs to be aesthetically pleasing then you...
Yep, the way our physics teacher explained it: if you put your hand over a pipe and then put a vacuum in the pipe, there's nothing in the pipe. You can't pull against nothing so it's the something on the outside that's pushing, not the nothing on the inside that's pulling.
Apply for a log book, they will send a letter to the current registered keeper. If the letter goes unanswered they will send you a new log book in your name.
They are slow, noisy, create a ton of dust and only take off millimeters. Once you're through the fat of the concrete they are very slow going. Fine if you want to key a floor for paint or remove just the fatty surface from a too-wet pour and float but not much use otherwise.
GEt a 5" grinder. You can put 4.5" discs on them but you can't do it the other way round. Even the cheapo Aldi ones are capable enough if you don't horse them.
