BP1064 Slitting and Drifting
by Uri Hofi
The chisel.
Mark the bar with the chisel.
Pour some of the lube into the mark.
Hit the chisel with the hammer only 2-3 times.
Pour more lube into the hole. Repeat with the hammering and lube but DO NOT go all the way through the metal.
Turn the steel over and repeat the same process from the other side.
As the chisel will go through the metal this time, use a cutting plate to protect the face of the anvil.
Mark the metal with the chisel, pour lube into the mark and hit the chisel with the hammer 2-3 times.
You can see the fire that comes out from the slot because of the coke burning.
Hammer the chisle into the steel and add more lube until you complete the slot
.
The finished slot.
Drifting
Align your drift into the hole.
Place the metal and drift over a prichel hole so the drift can go through the metal.
Hit the drift with the hammer 2-3 times.
Remove the drift from the hole.
Pour more lubricant into the hole. This allows the drift to slide through the metal easier.
Hit it 2-3 more times and add more lube. DO NOT go all the way through the metal.
Turn the metal over and now pour in lube and drift from the other side.
The finished hole.
