Chris, Even if the flycutter works for the tool post, will you be able to get in to do the holders with the fly cutter? Nick |
| raynerd:
Tiz a good point Nick. I`ve just seen Stews post on his gauge he is making and he used a boring bar style tool in effect to fly cut the material out. If you look back to the original post that Darren got his inspiration from, after taking out the main channel with a end mill he then took the entire dovetail cut with the dovetail cutter. I appreciate they are delicate but I have seen them used progressively to take the entire cut. No doubt if you removed some of the material first with a profiled fly cutter they would save the life of the dovetail cutter but I`m sure it should be able to do the entire cut. Think I need to use more coolant and a slower feed..... :scratch: |

...also reading the other thread on QCTP`s and I wish I`d read Darrens advice earlier regarding doing the dovetails first - If I mess these up then the whole thing is scrapped and I`ve since spent much more time boring out the centre :bang: |
| NickG:
It'll be ok, just take a step back and be patient. The amount of parts I ruin because I get over confident and take bigger cuts to hurry things up ... I'm getting better though. Nick |

I envy you fellows with shapers. Not having one, I made a dovetail cutter with a carbide insert and it works pretty well. You still have to go fairly slow but we have lots of time in the home shop, right? It's made from (what we call over here in the states) 4140 pre-hard. |
