Makes you feel old when you out lived the life of your tools.....

Anyway how close do you think you are coming to the water jacket in the block going .010" deeper than the insert thickness? Does anyone know how much room we have here to the water.....Hate to find out the hard way, maybe someone else has??? Probably plenty of room but that nagging little question always arises anyway.......

Forgot to mention I used to use liquid Nitrogen (boils of at -320 DegF at sea level) to chill the inserts and they would drop in mostly on their own. Liquid carbon dioxide would probably work and is not as cold about -80 DegF so is a little safer to handle.....But either one will immediately cause frost bite or freeze your eyeball....wear a face shield Bubba.....
