Chain drilling.
I took Marv's suggestion.
What could go wrong?
(Okay, maybe it wasn't really his suggestion. But he did mention it!)
I spotted first. I don't know if I had to but it gave me some security.
Then drilled every other hole.
You can see the problem I was going to run up against.
Then went back around.
Seems to me doing every other hole was better than when I chain drilled the slot.
Seems like there's a little more meat to keep the drill bit 'straight'. When I chain drilled the slot you could tell the drill bit wanted to shy away.
As you can see, because of the holes I'd drilled for clamping I couldn't get all the way around.
So I put an end mill on, came into the big hole, and knocked off the remaining parts.
I think it went well.
Now I've started milling around to get to size.
You can tell by the outline I have a way to go. I probably could have gotten closer to the outline with the chain drilling. But better safe than sorry.
Once done I'll put a clamp through it, remove the little clamp I made for the other one (it's behind the bigger clamp to the left), and have a go at it.
But I've been called to dinner.
Russian Vegetable Pie!
One of my favorites and she knows it's an easy way to get me to stop what I'm doing.
She has several tricks like that.
Fooey.
Delicious. Well worth the fun in a day or two due to the cabbage.
