| Powder Keg:
I tried to get the con rods made up. I ended up donating 2 of them to the scrap bin. The .3125" reamer chattered really bad. I had my mill going as slow as it would go? Maybe I'll have to learn about D reamers? |
| Rob.Wilson:
Hi Wes Looking good mate :thumbup:, sorry to here about the con rods ,we all have days like that Regards Rob |
| Powder Keg:
Im going to try and make me a couple D bit reamers\o/ I'll do it tomorrow or the next day. |
| Powder Keg:
I have a good start on my D bit reamers. I just need to grind the end relief on it. I don't think I'll even heat treat them? I'm just cutting brass. :wave: :wave: :wave: |

Hi Powderkeg, I just wanted to say, for a "D" bit type reamer for brass or bronze, one can merely cut off a piece of drill rod at an acute angle, stone the angled face to a nice finish, and harden it, or do the same with a piece of cold rolled, and case harden it, and you will get a good working reamer that will ream a very nice tight hole. If depth is a problem, you can cut off most of the sharp tip, just don't cut off behind where the full diameter is, and it will work quite well. These also work well in aluminum with good lubrication, and on a one or two time basis on steel. They have a tendency to gall in steel so lots of cutting oil, and don't temper at all, leave glass hard, and stone with the finest stone you have. This is also known as a "watch maker's reamer" or so my grand dad told me. mad jack |
