Thanks for the endmill explanation Mr. DKM. And nice work as always Mr. Bogs. |

--- Quote ---I wish someone would come up with a tool that does backwards countersinking. --- End quote --- Something like this perhaps? This is shaped to round over the ends of boiler stays but I have seen similar for studs. Starting to look like an engine now, keep it up. Jason |
| Bogstandard:
That is it Jason, but with say a 90 deg angle instead of being rounded. Many thanks for the picture, that shows me exactly what needs doing. A bit difficult at this time, but still attempting to get two hours a day in. John |
| NickG:
Very nice John, Nearly there now. I will be trying to get back in the shop / garage tonight after my month and a bit sabatical, starting with a good old clean up! Nick |

Very nicely done in all regards, John, like so many others, the ways and means you use are quite often new ideas for doing things, and will be faithfully carried on. As an aside, I've noticed on some of my cheaper, read "chinese" center cutting end mills, they get rather a lot of angle on the end cutting flutes, and if centered on a short stud or such, could be used to clean up the end. I hadn't thought of it myself, but I believe it would be rather easy to take a stone and increase that angle, and add some curve to it, making it cut much like you describe. I hate the look and blood of unfinished studs and cut off screws, and usually bevel them with a belt sander, or if they've been cut off in situ, as yours, carefully with a small file, although that seldom gives as good an end result. I want my stud end square, the threads ended with about a thirty degree angle, and the "tail end" of that last thread chased with a file right down to the smooth flat end. Easy to do with rod and a belt sander, a bit of work with file and not leaving scars on finished surroundings. All in all, a very fine looking engine, and that touch with the crank counterweight is a "crowning touch". :beer: You do very fine and artful work, Jack |
