31°F and clear skies this morning, going up to 48° today.
Having a cruddy day at work so far today. I've had one guy trying to justify that we cannot seem to drill a round hole, but it's OK, even after the customer had just complained about the holes not being round (how on earth do you drill a triangular hole with a round drill bit in a drill press?!). Another guy is telling me that the parts our customer just rejected are fine. A machine operator is trying to convince me that our best welder should just "make do" with the cruddy parts he made for him. What the ...?!?!?! What are these people smoking today?!
Gaaaah!!! Need to make a fresh cup of hot green tea, close my office door, and listen to some nice, relaxing classical music.
Irregular shaped holes in thin parts are frustrating. Some call it bell mouthing. Seems in every piece of metal, there is a lurking force called chatter, that is begging to show it's ugly head if you don't have the right tooling. Drills walking around trying to find their sweet spot is one case. Try ordering a set of screw machine (stub drills). Split point is usually better for starting with no punch or centerdrilled spot, but can not be resharpened unless you have a major high dollar grinder to do it super accurately. Mfgs offer 118° - 135° drills. this can have an effect. I find that the best drill for thin sheet metals are the stepped drills that can drill from about 1/8 up to 1/2" incrementally. They actually chamfer the hole too if you are careful with the depth.

Ed, you are a very good man. I hope your boy has a great birthday.
BEF, more prayers to "git" over what's ailing you.
PJS, sorry about your week of losing people you know.
I'm an old rocker, and not a huge fan of the classical stuff. I used to have a co-worker who would play it quietly in the background while we programmed for the CNC machines. Different strokes for different folks. I do love hearing Diane Bish rock the halls of old stone churches in Europe.

It is cold and raining here. Miserable. Don, I might just have to ante up and build a fire today too. My wife and I took our daughter to the doc to draw blood today. They are going to somehow check for possible food allergies. I think it it more horror-mones as she is 10 now.
RNG, I don't miss traffic jams for 1 second. Hope you keep making progress on your restoration.
I love to look at the newatlas.com website for innovative stuff. They cover a wide array of interesting subjects. Lots of good "click bait". The other day, they had a 50hp yanmar turbo diesel Outboard engine (made by Steyr motor group in Austria). It was really neat with twin counter rotating crankshafts for only a twin cylinder engine to put it into perfect primary balance. You have to see the video for yourself Picture is worth 10,000 words, video is a couple orders of magnitude more.
