Dovetail Cutter...Failed...
kvom:
If you can clamp the work vertically, then lifting on the return stroke wouldn't matter, I believe.
Darren:
I've been thinking about this one all day since I read it earlier......I'm not sure, would it make a difference?
Darren:
I decided to have another go at this tonight....practise make perfect as they say.....well making these things certainly doesn't faze me now..... :)
Do ya think this is a bit big for my lathe?
Only kidding, I'm going to cut a bit off the end for a bit of stock.....after visiting the miller for a bit of prep it was looking like this. No idea what grade of steel this is but it didn't leave as good a finish as the last piece I was using. But good enough for now.
I decided to stick my milling vice on the shaper to see if it would improve over the pillar drill vice I was using.....not 'alf, much more rigid and the workpiece never jumped out once... :lol: The vice looks a bit oversized in the pictures but in reality it was perfect. If/when I get a new vice for the mill this one has at least found a new home...
Close-up of the cutter. This time I locked the clapper and what an improvement. No more damage to the dovetail by having the clapper lifting on the return stroke. What's more this cutting tip cut on both forward and return strokes quite nicely.
Ended up with a nice smooth dovetail and a good fit...... :)
A bit more meat on this holder so I can machine a slot for the parting tool shank and secure with grub screws. I might reduce the parting tools shank from 25mm sq to a more reasonable 20mm to make life easier.
websterz:
Is that blood I see on top of the new toolholder block? :bugeye:
Darren:
Oh yes indeedy, it bit me....savage little Blighter that one.......
Well spotted........ :lol:
