Thread: Jim's diagonal dots

Hi Toni
nice pens, what angle did you use? I was thinking of going 45 degree or more and figured to get ovals ... but I'm still waiting for parts to fix the bandsaw beast

Colour contrast is good.

Uummmm I stuck it in the drill vice at a what angle I thought looked good. and pressed start...So I have no idea. I did think I would get more oval I was bit dissappointed actually
Toni

Just as a rule of thumb:

30° gives an oval about 1 1/6 times as long as it is wide
45° gives an oval just under 1 1/2 times...
60° gives an oval about 2 times...

Good work Toni.
As the others have indicated the more angle the more oval.

ok back to the drawing board. Thanks for that..ok now another question for you..How do you get the drill to bite in at the beginning of such a steep angle?
Toni

Hi Toni,

Try clamping a block of wood on, that has been cut to the angle you want so that the drill bit has a flat surface to start with

ok thanks Dj for that

A good library can hide an ocean of ignorance... if you know how to use it.

Touche' ...

or 'scorched' ... I guess

BTW, Toni, I find it's easier to cut two of those wedges at the angle you want and clamp one on each side. (I hot-melt glue 'em on and remove 'em in a microwave later, but it's still the same principle.)

That way you don't normally need to change the drill-press table from its' usual position (mines' a right beggar to put back accurately. ) and the bottom wedge protects the blank from tearout when the drill passes all the way through.
