    cutting stainless steel tube

    lol sorry gcol - assumed you were psychic for some reason. well in the end used an abrasive disc in a drop saw and got used to the angle of drift in the cut, so I could adjust my cut to take it into account. got squareish cuts but appalling burrs - these i removed with a file on the outside...

    cutting stainless steel tube

    thanks for the replies. I have got about a hundred to cut, and cant finish them on a lathe as the tube is rolled to a curve - in some cases a 4metre radius curve. the problem is that i have to cut them exactly on the radial of the tubes curve - so a hand tool is no way accurate enough. so far...

    perspex

    sanding clear perspex never gives a uniform translucency, the scratches always show. the process that would be equivalent to etching it is to apply a solvent, ideally you would use ether as a solvent but it is very hard to get hold of nowadays, cellulose thinners works, but again it is not...

    soldering mats ....what do you use .....

    That isnt such a bad idea. ALL silicon is heat resistant beyond the melting point of solder, even the clear stuff that you use for glazing and to seal baths. so I suppose in theory you could smear a thickish layer on something (like old fibreglass curtain fabric) and make yourself a soldering...

    Compound Mitre Saw vs. Flip Over Saw

    I've had a dewalt 743 flipover saw for at least ten years (well ok it was made by elu then, but dewalt rebadged it) and it has always done everything ive asked of it (including converting 6" oak to planks, along the grain in two cuts). I got it because the cabinetmakers where i worked had it as...

    Bolts

    could always resin anchor in some good old threaded rod. that way you'll only have to drill holes the size of the stud. m10 at a guess.

    most used tool

    was going to say my estwing hammer, a gift from an old friend, had it years and It feels like an extension of my hand. but thinking about it - the most used tool is my toolbox, the small portable one that goes everywhere. and to be quite honest it is bolleux, a broken catch, a nasty bit of...

    overhead fixings to cast reinforced concrete

    I need to support a series of steel frames to the ceiling of a multi-storey car park and have been told that the reinforced concrete that the slabs are cast from are quite a lot harder than usual, and that most existing fixings have needed diamond core drills. As all the work will be...

    Dormer window woe

    when i was a student, behind with my rent, my landlord said he would let me off the debt if i agreed to paint the outside of the house, if not I would be evicted. no brainer really. a few days later this guy turned up with some rusty old scaffolding and put it up in the sliver of front garden...

    near misses

    Not sure if these count as near misses, but none of them have affected me that I know of yet. As a kid I used to like to taste things, one of my favourites was to pick the fibres from the decayed asbestos roof of the shed and chew them. then a while later my sister got a job as a radiographer...

    potty 80 CH failure question (number 9000)

    Well i went and bought a diverter valve, the whole assembly (just the wax capsule end wasn't significantly cheaper to cost the extra time it'd take to get one). and guess what - it is like having a new boiler, it heats up quicker than ever before and is quieter. for the record I only fitted...

    Hot Cup = Heat Stain (in Ducal Top) = Dog House

    not sure what you mean by 'ducal' but i do know a way of getting heat rings out of varnished or french polished wood. mix some cigar ash with water to a thick paste and smear it on the ring, it works a bit like a stain - will make it almost invisible. then if the polish is damaged use a...
