Make your own machinable wax

wax

No matter how easy it is to throw a piece of metal or plastic onto a tool and start making chips, the price of materials does add up. [rawkstar320] has been using machinable wax – a very hard wax that is up to the task of being cut with tools spinning at thousands of RPM – to reduce his material cost, simply remelting every part with a mistake. This wax can be made at home, it turns out, and [rawkstar] is glad to walk us through the process.

The creation of machinable wax begins by melting a few pounds of paraffin wax in a home deep fryer. Machining pure paraffin would gum up the works of just about any machine, so [rawkstar] throws a few plastic polyethylene bags into the already melted wax.

After casting and cooling, these blocks of wax are ready to be surfaced with a tool and milled into any part [rawkstar]’s workshop is capable of. As a bonus, all of the chips produced from this wax can be recycled and melted down again making for a somewhat renewable material that is perfect for prototyping or casting.

Laser based night light


[the4est] put together this quick how to for making a laser based light bulb night light. First, you need to break out the black glass base of the bulb and remove the filament. Scrub the inside of the bulb and pour in the paraffin. Once it sets, you can break the glass, leaving a solid wax bulb. Hollow out the inside, insert a laser pointer, and you’ll have fine glowing night light.
