Fly cutter

Any one have a cunning idea how to mount the cutter to this, I made it but can't decide the best way to go about it, thought maybe through the edge at an angle with a flat milled on one edge of the cutter and held in with a grub screw, any good ideas out there.

Cut a notch and screw the insert onto the face.

Or this

Brill Al' will do that put one at each side.

I'd probably do a single, unless you can position them both to within 0.001" you will find one does all the cutting. Maybe just notch the other side to balance the disc.

Thanks Jason that's a great idea will try to do something this weekend.

Finally got round to fitting the cutter to the fly cutter only thing is I snapped the tap in the hole and theres no way to get it out, but not to worried because I was going to mill out the same amount the opposite side to try and keep it balanced, does any one know of a long slender tap holder that will hold M3 M4 size taps.

Regards Al.

drill a hole in a bit of rod and loctite the tap into that, bit of gentle heat will get it out again

[Alan .204Participant @alan-204]

That sounds like a very good idea thanks Jason.

My blue nose will get it out!

Hi,

I've thought about making one of these. What I planned to do was to cut a blind slot in the "cutting" face and Loc-tite in an insert.

Mark,

That would probably work OK

… Best to use 638, I would think.

… But please do bear in mind that Loctite degrades at about 200°C, so don't let the tool overheat.

Alan,

Did you use a blank end arbor to make the flycutter and if so how did you affix the disc to the arbor?

Thanks,

Mark

[mickParticipant @mick65121]

Just out of interest, what kind of speed were you thinking about running it at and how are your spindle bearings?

[Alan .204Participant @alan-204]

Hello Mark managed to get the steel disc from a friend of mine and the arbour from RDG I think. machined the disc and bored out the centre smaller then the arbour, then turned down the arbour so I had a real good fit, I made a recess on both sides of the arbour and welded it both sides then put back in the lathe and machined it true, used a stick welder, I think the mill would break in half before the fly cutter would.
