    4 PLY , No Problem !!

    If you do another one, see if you could set it up with a hamster and a hamster wheel. Make the hamster's path to the food through the wheel. Maybe have the option to create a 5 ft diameter roll of TP. Oh no! I've slipped over to the dark side. (Please tell me you're not my father!)

    How to properly mix and pour concrete

    Here are two sites saying pretty much what I said:http://www.directcolors.com/product/chopped-concre...http://www.eng-tips.com/viewthread.cfm?qid=195567You can put ordinary fiberglass in your concrete if you want, but you'll have problems.

    If you use fiberglass for added tensile strength, make sure it's alkali resistant. Ordinary fiberglass won't work with cement. It will degrade in time.

  • Make a carbon arc torch for your 220 volt stick welder

    I'm not sure what they used to advance the rods back in the day of motion picture illumination, but here's a video of a more current attempt to create an arc lamp. One of the rods might be advanced by use of a stepper motor driving the frame that holds the rod:https://www.youtube.com/watch?v=u8e_u_xqN30

    Thanks for posting your instructable. I think I want to use your info as a starting point for a project I may build. I'm mulling over building a carbon arc lamp. If I had a way to feed the rods towards each other at the right rate, and had a 100% duty cycle welder, what's your best guess as to how long 12" rods would burn before they were consumed. I'm sure you've never sat and timed this, but any thoughts, musings, or feelings on the matter would be appreciated. Thanks.
