Re: [EVGRAY] What is this?

Body

GeorgeThe big 5/16" torx drive screws which are either 4" or 8" long can be driven all day on a charge usually.The gun goes into impact mode going through a knot, or tough wood.The battery is a clunker which charges in less than 15 minutes at the end of the day. Look up Dewalt 20 volt drivers and lithium batteries.I don't know if you have the square Robertson headed screws where you are, since they were a Canadian invention, but they are perfect for # 6,8, and 10 screws, working very well using prepared deck screws on1 1/8" pine barn wood planks, onto the posts and beams.I hate working with Philips headed screws.Cheers Warren

 Warren,
Tell me more about the Dewalt impact driver and the battery.  What is the rating on the battery and the model number of the impact driver?  I might buy a couple of them as ours are nearly ready to be replaced.  I'm also amazed at how much work they can do, but it all depends on the size and capacity of the battery.

You know on the multi tap transformer I used to step the voltage down on the series capacitor run circuit of the RV?There was that test I did using my Rene charger using the 20 volt winding at the same time which oddly enough did not raise the load amps to the little 5 amp battery running the whole works including the outboard motor.I still have everything, more or less, scattered about various farm buildings, from that experiment.I didn't consider the results so surprising, and feel that the entire setup can be looped in several different ways, using batteries.Rebuilding these barns, using a Dewalt 20 volt  brushless screw gun, and lithium batteries, driving four inch timberlock screws all day, has enlightened me a bit regarding what one can do with batteries.Those tools are magic technology.My steel gusset brackets, and the 20'x6"×6" lodgepole pine beams are super quick, and adaptable for framing. The Stihl chainsaw is my friend in this game.Toiling away on the ground, with tons of stone on the property, the old used Catepillar excavator, that I made hydraulic stone grabber lower jaws for, has paid for itself twenty times over. We just use it for everything heavy now, and a lot of stuff around here is heavy, like the 8"×8"x20' posts which it lifts and puts in place easy as can be.The Dewalt cordless is still king with that battery that outdoes the Everready bunny, I used to make those commercials for.The charger seems to take less than 15 minutes to charge the battery. The brushless motor in that tool is unbelievably powerful going from straight drive into impact as the torque demands it. There has been some serious design thought going into these tools.All carpenters are using them now.I might try to run the big Kromery with the drill.We still have the awkward battery charge swapping and changing battery issue to deal with, but I am pretty sure there is another way to loop in there.Industry is creeping up on us when we aren't looking.We should take full advantage of the good ideas.Cheers Warren

HI KONE  ,I have a RV motor set up to play w/and have not seen that new RV circuit..OR MAYBE I HAVE & DID'NT NOTICE!!Could you maybe send it ?

     Hi Warren
I assume that extra HV DC from the bridge shoves itself back into lead acid battery powering the invertor that feeds AC intootor to run it as you know you can hat away when using big lead acids with running HV DC into them to charge them.
So sort of like amps comes from series transformer and voltage comes from HV FWBR and they coheree when paralleled into lead acid battery as the "recceptacle" of each.
There might be something going on when that output from series transformer and the HV DC combine togetherr in parallel looping back to DC source of the lead.acid battery that is not realized until the experiment is done on bench
Hector has put up this "new" RV circuit 20 times at least and still nobody with an RV motor to play with has tried it!
No big problem if start up needs a cut out switch during stsrtup.maybe it doesnt...
I see where an invertor that simply alternates low voltage or higher voltage DC into AC by swapping polarity flow everyyother pulse could be looped back.into the RV motor and caps could be.used insread.of a battery. ( maybe electrets!)
Also that HV DC could be fed into a 2nd Dc type motor, such as treadmill or universal ACDC washing machine motorr and belted to shaft of RV motor to give.more torque, maybe make stand alone looper like that
