Malanka Posted October 26, 2017 Share Posted October 26, 2017 Tim me old mucka don't forget five cuts is five slices the thickness of the blade to be subtracted from the length. Otherwise your last bit will be short..LOL And oh high panjandrum and font of wisdom... This aint America hunny its maths.......... Let's leave "bustin some moves" and that's a "ballin" car and stop "flossing" to our cousins across the water please. FYI Flossing does not refer to teeth...

But I'm a historian so in English its Math. (with the full stop), not until 1911 did mathS with the added 'S' start to be used. I got my first mathematic wrong so when I ended up with two mathematics I was in trouble...now my plurals have gone wonky...I've caught pluracy! 2 minutes ago, grendel said: Tim - I once made a Plainer sled, it was just two runners on a sheet of ply - it worked well when the snow was deep enough.

Paul Posted October 26, 2017 Share Posted October 26, 2017 11 hours ago, HakunaMatata said: so far I know, after having done the five cuts and did your calculation, it has to be devided by 4, the 5th cut is just to get your peace to measure the alignmend. such is my understanding of the five cut method, you divide by four being the number of edges you have cut from, discounting the first cut which is only done to create the first edge, so the fifth cut is made from the fourth edge hence creating four multiples of your variance. You then measure the variance and divide by four. At least that's how my father taught me, he was a Master Carpenter. I know I haven't exactly explained it very well. I used that calculation when I built my wall mounted panel saw, and found the result to be quite accurate, but eventually invested in a dial indicator which I don't think is any more accurate but much quicker.

Buy a decent vernier and measure as you go. What material are the tolerances being measured on? Richard ......it's a caliper!!!! Quote Link to comment Share on other sites More sharing options...
BroadAmbition Posted October 26, 2017 Share Posted October 26, 2017 When I'm cutting wall / floor tiles be they of a man made material or provided by mother nature, I work to a tolerance widely known as a 'Gnats Knacker Sack' Whether this is more accurate than 'Gnats Cock' is open to debate Griff 2 Quote Link to comment Share on other sites More sharing options...
Wyndham Posted October 26, 2017 Share Posted October 26, 2017 We had 2 standard references for the inaccuracies of our work, one was a frazmo, if it didn't fit take a fraz off and it'll be fine. For finer work it could be a traumalasence out. This would require a traumour to be removed to correct the problem. I should add these ISO standards are for metal not wood or tiles as sawdust and tile slurry both compromise accurate measurement. Quote Link to comment Share on other sites More sharing options...

Having never measured the ******** of a Nematocera I'm not sure quite what the exact size is. If I ever said to my father "that's close enough" he would say measure it again. Once it was exact his reply was "that's close enough". 1 Quote Link to comment Share on other sites More sharing options...

KaptinKev Posted October 27, 2017 Share Posted October 27, 2017 There seem to be a few intelligent boffins on this site. Lucky for me in my job it's basic math of add, subtract, divide, measure twice and cut once and check the bank balance to make sure the money has gone in. 1 2 Quote Link to comment Share on other sites More sharing options...
