I'm definitely not criticising here, since I've watched most of your videos and would love to have had you as my teacher at school, but some of you might not know that there are metals that expand when they cool.
Bismuth and Antimony (elements) do it, as do a number of alloys containing them, like Babbitt, Britannia and Pewter. They are useful for things like letter sets in printing presses, because they melt reasonably low and pick up the fine details on the characters as they fill the voids.
Have just watched your 10 part video on constructing the 21/2 x 25/8" wobbler.
You are indeed a boon to model makers.
It is also refreshing to hear that I'm not the only one dismayed about the cheap chinese import crap we have to put up with. A wornout Bridgeport or Atlas is still lots better quality and more accurate than a chinese grizzly and such.
as a matter of fact, on engine blocks there are two different plugs - core and freeze. it's just a common misconception to call core plugs freeze plugs. core plugs are indeed installed where core was used for casting, but freeze plugs are expandable plugs on the block that prevent block from cracking if the coolant freezes. they just pop out
Northern Wisconsin -- that's like Canadians with Green Cards! LOL! Keep up the good work on the vids -- I'm thinking about adding machining to my woodworking and welding skills, and your videos are helping sooo much in figuring it all out.

Very informative videos! You said you're from Illinois, but your accent sounds like Eastern Canadian (maybe Nova Scotia). Am I close?
