Ideas for a counter balance


I am looking at ways to replace the weight of the batteries in a cordless drill (the batteries leaked, and they are not sold to my knowledge anywhere in THIS country); after wiring in a power supply (making it corded).  

Any suggestions?   I have thought of a few but nothing seems overly viable at the moment.

How about a bunch of rocks?
Goodhart (author)  jeff-o5 years ago
I'd have to take a trip out into the countryside to pick up some rocks. I have to get over this blue funk I'm in again and get to it....with SOMETHING....I have an idea what I could use but I need to rig a double boiler for heating the plastic "stuff" to make a crude container for the weights I put in.

If I'd been young again, I could have gone trick or treating in a Charlie Brown ghost sheet with lots of holes in it and gotten a bag of rocks..... :-)

i think lead will be your best bet

to make a mold all you have to do is shape some clay or plasticine then make a mold of it using plaster, do it as a 2 part mold.

then melt your lead and pour it in the mold, i would make a battery size mold then you can just add as many as you need in the same place as the battery. and with the 2 part mold you can get the lead out easy.

Yes, as I have a lump of lead already that is around the proper weight, this is kind of what I was thinking of.

Stacks of metal washers, wrapped in paper (like rolls of quarters)?

Cement, moulded into the desired shape?

Hmm, the nice thing about the washers is I could regulate the weight fairly easily, and substitute more or less of the plastic "stuff" I mentioned to Ninzerbean, since I have that on hand already. Thank you.

If the plastic "stuff" you're referring to isn't Sugru, I might consider that stuff. Its pretty much the coolest DIY stuff out there. In fact one of their examples is a drill handle. http://www.thinkgeek.com/gadgets/tools/e976/
Goodhart (author)  aRKayy5 years ago
Well, I would need quite a quantity of it, and so that is not so cost effictive. No, the "stuff" I refer to is little granules that get heated on a double boiler, and at near the boiling point of water, it melts. I don't expect I will be using the drill in weather that is hotter than that, so I have no fear of it softening again after application :-)

Wet sand?
Goodhart (author)  Ninzerbean5 years ago
Hmm, well I'd have to seal it somehow for it to remain wet, but that would work...I have to plastic molding "stuff" that could be used as a container (melts in a double boiler and you pour it into a mold). thanks
