    Unusual Uses for Vaseline

    While PJ seems to have "been around forever", like any/most lubricant it can be used on "high friction (rubbing) areas on; drawers, doors, windows, etc. However, I believe PattyS mentioned about jewelry - in which we used PJ on Opal rings & pendants to "cover the Opal stone" & wipe off excess - to be absorbed. It protects the Opals from excessive damage to changes in heat. Like coming in from winter and removing a pie from the oven. The cold vs oven heat can make them shatter or explode. Keeps them safe & intact.

    Quick Made Hand Cranked Compost Shredder

    Many years ago a company that made a gas powered "chipper/shredder" - that DID NOT use spinning blades. They had 3-6 shafts each having multiple hammers (flails) to smash the small pieces of wood by spinning on their shafts. Very old mowers used this concept - and even today most state highway departments use heavy-duty flail mowers along highways. The number of "flails" correlates to the size of the debris. Some universities use this apparatus to separate "seeds" as well.

    $50 Plastic Shredder / Grinder / Recycler

    There are older shredders that can eat 3-ring binders! But, paper shredders are designed to shred paper. Maybe a "blender" could shred your plastics small enough to - then use a crosscut shredder. Your savings in; time, money, and electrical usage, will be reduced considerably. OR 3-4 shredders of varyin shred size & power, and reduce your plastic in "stages" vs burning up shredders.

  • Bottle Cutting With a Soldering Iron

    Maybe you could make a "jig/rig" to hold the soldering iron tip - against the scoring line, and simply rotate bottle - while adjusting "in" soldering iron tip ?

    Plastic Repairs (Gas Tank Example)

    I'm curious about 2 things. Was there a reason why you didn't put a "patch" on the inside of the tank "prior" to your outside patch ? Secondly, I don't remember any suggestion regarding gloves - for dealing with hot objects ? Was there No reason for protecting fingers/fingertips ?

    Very nice & informative idea. Believe it may fare better (for voting) - without the antics though.

    12" Disc Sander

    Very nice workmanship and attention to detail ! Wondering how well your dust collector worked or would a "shroud" around disk perimeter work better ? Did you glue & screw the threaded flange on rear of disk or just screws ?

    8 Pool Noodle Life Hacks & Diy's

    I've used pool noodles on my Jon boat to protect edges & keep boat quiet when fishing close to rocks, trees, other obstacles. Similar to boat fenders.

    I'm wondering - If your "cut can" had maybe 2 end-holes (for needle-nose pliers), then you could heat sharp edge of opposite end and use to cut the noodle ? Has anyone tried this ?
