I doubt it would get all that much use. Most of the working out, setting out and cutting is on the ground and much now offsite. The onsite work is more leggo assembly stuff (or for blokes my age meccano!

). But who knows what might interest younger workers in the industry. The other issue for me is that I've always treated roof or any high work with great respect - I've seen too many accidents happen from the most simple little errors of judgement and minor temporary distraction with major consequences. Maybe it's just cautious old me - and I've had two close calls through no real fault of mine or lack of care or attention.

I still have and use the brass guides and my roofing square given to me by my Dad when I was about 12 - and the roofing table book too.

But I am all for new and fast so love the calculators - and the reduced errors (although get it wrong with a computer and you tend to have errors on a larger scale!). 'Skilsaw' shows your age too - maybe they are still going in NZ, but they haven't made (or sold I think) a product in Oz for yonks!

See this little bit of history http://www.thetoolwebsite.com/FAQs/Circularsaws.pdf and still selling in the USA - http://www.skil.com/

old aye? im only 25

maybe new zealands a little oldschool

the reason i like using a circular saw and roofing square is because you don't have to move the rafter very far, and when you've got long lengths thats great

So do you use the roofing square to set out the compound cuts for the roof? Or simply to guide the saw? I was taught to se the roofing square to set out the compound cuts, but I am not sure that skill is still taught (let alone used) as computers do it much better!

i just set the roofing square up to the desired degree then mark out the plumb cut and the seat cut, then cut it off with the skillie- theres a little jig thing ive made that goes with the roofing sqaure- im not sure how comon this is? ive never seen one for sale

sorry for the late reply ive been away working in some horrid small town

I mentioned the roofing square stops my Dad gave me. They look like the attached pic - mine are no longer shiny of course!

hmm interesting, they look like they do the same sorta thing

heres a better picture of my one, i made it from some left over jarrah the owners were using as a thermal brake in a concrete floor. [such a wast]

its just got slots cut down it for the roofing square to fit into and some others for some wing nuts to tighten once its set up.
