This might be a little off topic, but I thought it might be worth a mention. Many years ago, I saw a good trick for marking a pipe/tube at an angle, the tube in question being 8or 9 inches/ What he did was to spread a handful of soot on the surface of a barrel of water and having marked the pipe both sides, where it need to meet a flat plate, he lowered it into the water until both marks met the surface, then took it out. The result was a clear black line, showing exactly where to cut. So simple ! Haha. Brilliant. Maybe those old guys did know a trick or two after all! Another trick to mark pipes square that old boilermakers used was the previously mentioned wrapping a bit of paper around the pipe, but using a readily available strip of emery tape as the piece of paper. The 2" wide stuff works well for full sized pipework diameters. Edited By Hopper on 21/12/2020 09:38:31 |

2805 forum posts 219 photos | The technique illustrated in my picture is aimed more at avoiding burrs than squareness although this should follow: I have not included the accompanying text from Cliff Bowers' "Book of the Lathe" since the method seems self-explanatory. The off-cut would, of course, be retained on the leading toolbar. Edited By ega on 21/12/2020 10:33:48 |

![]() 406 forum posts 56 photos | The reason for not using a pipe cutter is that they dent the end of the pipe, Fine for inserting in plumbing fittings but no good to go round a boiler end plate. OK if the end plate is external though, although that raises the obvious question. So for an internal end plate the bung method is best.

Woody. Non- ferrous on a grinding wheel? - shame on you! |
