Cheapass dovetail cutting - fly cutting style

<< < (2/3) > >>

NeoTech:
Nah not really a good reason.. more than i have alot of HSS blanks now a days.. and ive made a small grinding jig for setting angles and so on..
But i do think that carbide tip on a proper toolshank is a better solution actually..

TCG, no idea what that is..

i have been experimenting with holding a small carbide insert tool in my fly cutters as well but i tend to break the tips more than once.

tool cutter grinder
Try that one on google  picture search - least looking all those different forms of TCGs keeps me entertained for hours.

I have good chunk of iron on MT3 and I put there baddest russian carbide bit I had (Somewhat bigger and thicker than CCMT09 with really BIG r) and never had a trouble.

The slender holder has been machined out of round rod (was easier to get angles right to something....that was long ago I forgot for what :lol:).

The attached holder is a funny one....I needed to cut on recess, therefore I need small diameter flycutter. I got my boring bar later. Maybe this explains something.

NeoTech:
Hmm, that actually looked quite doable.. I gotta make a try.. This gave me some water on the mill.. (ooh swedish expression badly translated) ;D

Jonny:
Assume its a 60 degree dovetail not a Picatinny or Weaver? Or both?
Done it in my early years and do have a handmade MDS the dovetails were cut exactly that way. Steel breach block held at an angle using conventional milling tools.

60 degree and 45 degree decent dovetail cutters are quite cheap. 3/8" from around £11 from J&L far from the cheapest place around. 1/2" price goes up, need to get some more.

NeoTech:
For the sight rails i guess its a 45 degree, but i wanna give a try at making picatinnys as well for accessories.. =)
