What voltage drill do you think I should use for heavy Duty legs ted to t/a van? Have used a 24v drill but that is heavy and a bit of an overkill.Want to purchase one to keep in the van.Any suggestions/recomendations welcome.
A decent 12 volt would be fine just for legs, my 12v Bosch has never had a problem. Bought a cheapo 18v to leave in the van and that was useless so back to the Bosch.
I think I used 10 batteries (10 x 1.2v = 12v) but make sure you get the ones with solder tags on. I cut around the base of the battery pack, which incidently had only AA60mWh Nicads 1.2v, stacked and soldered the new cells in series the same as the existing and laced them together with cable ties. The old case was far too small so as a temporary measure I used the end of a plastic milk container which was almost the same size but a lot deeper. Plenty of black tape around to hold it together and it has stayed like it ever since.
The charging time goes up quite a lot andI have left it over 24 hours.
The price of the batteries seems to have gone up since I did mine but you can get them from CPC order no BT01300 - part no GP200SCK1A1P
Just had a quick look at mine and I'm really not sure how many cells I have used, it looks like there are only eight but I can't be sure. If you cut/screw open your battery pack and just replicate the number used inside you should be OK. I would think that this will only apply to the cheaper brands and I don't know what they use inside the dearer brands.
Niclel Cadmium cells (NiCads) are 1.2v each so divide the voltage of your drill (not the charger) by 1.2 to get the number of cells. 6v/1.2=5, 7.2v/2=6 etc. however a most manufacturers used various "non-standard" sizes of cell - see the Maplin website and you'll see that not only do they have, D, C, AA and AAA sizes but they also have, sub-C, 4/5 C 2/3 etc. So you'll probably have to cut the casing apart to get the correct cell size if you want to make it like new
As mentioned already, voltage is not important, but power, so go for a drill with a 2 speed function. Use the low speed, which will be fast enough for putting down the legs, that is what I use and it works just great. I think the voltage on that drill is about 14.2 volts.
