A little problem drilling...

[LCHIEN]

This is part of the project I'm working on...
I think its jatoba - Brazilian Cherry.

This piece didn't want to drill too well - sort of shattered when the 2nd hole drilling intersected the first hole. THis was the 2nd or third piece I drilled.

Was holding the piece in a angled machinists vise clamped to my drill press table with a MLCS brad point drill bit. Used the depth stop on the DP.
Hole in the side grain is 5/8" at a 8.5° angle off vertical. Hole in the end grain is vertical (0 degrees).

Slowed down the feed rate in the rest of them, when I knew I'd be intersecting the first hole.

Good thing i cut a few extras... as usual.

Anyone want to guess what this is part of?

Are they parts of the Marble Race from Dec/Jan 2012 Woodcraft Magazine?

Really bumpy wheels?

I can fix that. Some Titebond and some filler, it will be good as new. Worst case scenario, wrap it in some duck tape.

Marbles and Blocks set.
The Lee Valley description handily gives many of the dimensions you need to build the pieces.
