Introduction: How to Cut Hard Microcrystalline Wax
I did this at TechShop Menlo Park. http://www.techshop.com
A large chunk of microcrystalline wax is not easily cut or broken. We had to get creative with the solution.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Tried Using a Saw
And it gummed up the blade right away.
Step 2: Introduce Electrical Heat
We figured we would use a car battery charger to introduce heat to the blade.
Step 3: Charged Saw
It worked for a second but didn't get too far. Maybe because the blade surface being too big to send an even charge.
Step 4: Wire Cutter
Using conductive copper wire and two sticks of wood we created a cutter. It didn't work by itself but charging it helped.
Step 5: Cut
Electricity provided heat for the wire which cut through the wax nicely and easily!
Step 6: Chunks of Wax
The smaller chunks of wax are much easier to work with. I am using them for lost wax casting.
