Kitty liter is clay and a great insulator
The reason to toss it into the kitty litter is that way the Cast iron does not become brittle ( which it will do if chilled too fast)

Kitty litter or sand will give you the slow cooling desired

I am going to brazed in some brass rod where a tooth is missing. Since I don't have any metal working equipment I am going to hand file the profile. Any suggestions would be great! This is my first post. Tom It's a bit of a job but doable ! two suggestions 1/Drill a vertical hole in the gear and pu...

When making side cuts into a workpiece how deep can/should a cut go relative to the diameter of the end mill? ................... ........................................................................... What would a reasonable DOC have been? ..... The "rule" is no more DOC than 25 % of...

Short answer is No, It's one thing to burn through 1/2 " of steel , but the 30 degrees means the cut will vary in thickness from 1/2" to 1" and then back again that means the torch has to handle variations in thickness while moving (Variable heat requirements) and that usually means &...

Two different animals here. The Part is vertical, but is it loose for drilling, or is it mounted already Is the 33 degree angle from vertical or horizontal ? Or even Horizontal but at a 33 degree side angle ? Makes a HUGE difference IMHO Rich One good method involves a ball endmill (4 flute) but I w...

, well if the pins are 1 " , then you will gain .0028" Soak time is just needed to get the part to 550 and that depends on method of heating Hot air is slow- compared to contact or direct conduction. Put a steel plate in the oven ahead of time and when you set the wheel on the steel, it wi...

Pollysdad When bending metal, you follow the centere of the sheet , which is called "The Neutral Axis" in the bend, the inside of the material compresses and the outside stretches so a lot depends on the radius of the bend when doing forming. So do not use the outside or inside dimensions ...

I need to make a 12mm wide slot on the inside of a mild steel collar with a 40mm bore. .......................... The slot is a bit of a wide one; should I make a chisel the full width of the slot, or use a narrow one and work the slot wider a bit at a time? If the chisel is full width, should it b...
