--> MadNeck It's too cold around here to do something in the workshop, the last knop I did on my ball-tools was steenless steel and it was going well - no fooling around because of the balls - I think my biggest problem is, that I tried to implement a "diamond-cutting"-arrangement, and I did not get the right angle in the first place, so now I have to make a new "tower" for mounting the bit. If you do a ball in alu or brass it should be no problem I think. I will not at all cancel my "ball-bearing"-arrangement in my tools, but try to make a better arrangement for placing the cutting bit enabling adjustment up/down for better performance ... but it's too cold these days, so I'm doing "in-door-hot-coffee"-thinking :med: ..... and driving my wife mad ! |

Thanks Fellas, Time for a rethink, I mean, whats the point of reinventing the wheel? Nick |

Following our E-mail discussion last evening, you have a boring head but with an unknown taper shank. In other words, you have most of the tool which will kake balls and whatever- if only you could get rid or find a solution for the spiindle/shank. All that you need now is three things 1. a decent tool to do the cutting 2. a spindle 3. a holder of sorts which takes the new spindle but at lathe centre height |

There is a member on Hobby-Machinist that used a flycutter as part of his ball turner. It does allow some adjustment and tool possibilities. You may have to be a member to see the photos though. http://www.hobby-machinist.com/showthread.php/4570-Another-version-of-a-ball-turner?highlight=ball Joe |

Nick, Sorry to hear it's not performing to expectations.... I know you may be thinking of the boring head version but I can assure you that this version will work if you take a direct copy of Steve Bedairs design (turret mounting etc) and my tip adaptations. No bearings to have play in and you can make the turret to fit the recess in the base. So no need to panic over accuracy of dials etc. (I know that my dials are no where near as good as they should/could be according to the books!) Scream all you like carbide bashers of the world....(I'm getting fed up of people telling Newbies that carbide is useless!) I have many photo's and videos that prove that these things work perfectly well with carbide tips! Feel free to check my videos on youtube. eature=mhee Every single thing on the lathe created with mainly carbide tooling... My only HSS tools are a micro parting tool (used for grooving only) and a small boring bar. I've no issue with HSS in general.... I just don't use it on my lathe that much. The issue with HSS tips for these tools is re-creating the exact tip when it needs sharpening/changing..... you have to re-calibrate the tool (lapping and setting to exact length etc) and could possibly lose hours trying to get it accurate again! Apologies for the micro rant Nick.... I just think you have more than enough talent to make a working tool the way you are going. :thumbup: Ralph. |
