yes good afternoon YouTube's I am running my drill press today drilling some holes through
some mild steel and what I wanted to do was see what kind of power and inverter current
that load takes and so here's my kilowatt meter I'm reading the power coming out of the inverter
going into my shop and I've got the inverter DC current that's 12 volt inverter right now
of the charge controllers putting about eight amps into the batteries I've been running the
drill for a while so I just wanted to see what kind of power and current it takes while under
load so I figured I'd run the video and we'll both find out together so I'll try this and I'll
do a little drilling and then I'll come back and make a little change I'm drilling about
a fourteen millimeter 9/16 inch hole in some mild steel so what I want to do is also check the yeah
why don't we were checking the volt HAMP's so I just want to see how that compares to the Watts
okay so that was running the volt amps now what I want to do is try the power factor there so what
we can do is check the power factor when it's running okay so that was the power factor and
then what I want to do is I'll do the same test but over here yeah so here I'm going to plug in
this is a there we go get in the frame there 30 micro farad run capacitor so I want to see how
that affects power factor and current so I'll plug that in now so I'm going to run the drill again
okay and let's go up here we'll try the will do the volt amps so I'll kind of go back through
the same settings okay that was that test and now let's run I'll run the watts okay so that's
the last test I want to run and actually I notice there I stalled the drill out and I didn't trip
the inverter sometimes it'll trip if I don't have the power factor capacitor in there that kind of
want to run this test to see if it makes sense to look into some power factor correction for
that drill you know it's just your basic AC motor on there so just see what the numbers look like
here okay so let's take a look at the numbers I recorded off the video what I did was I picked a
similar DC current into the AC power inverter to take my various measurements at so I used about
80 amps on the DC meter and then at that point I measured 785 AC Watts 890 volt amps and 0.78 power
factor and if you calculate the AC amps but I get seven point four two amps and if I take those
numbers and I plug the Watts the amps 120 volt 60 Hertz in hit the calculate button that gives
me a correction capacitor of seventy-seven micro farad so that's what I've put over here I don't
have a 77 micro farad capacitor but I plugged in my thirty micro farad and you can see in that
case the DC amps dropped down to about 66 amps the AC Watts at that same current was about 768
so I picked an AC power that was about the same as what I had before you can see the AC power is
a little bit lower but the DC current is quite a bit lower over 13 amps less the AC volt amps
has gone down our factor has come up and my AC current is now six point six seven a amps and if
I plug those same numbers in over here it tells me I would need about forty one microfarad additional
capacitance and that's just a good sanity check because if I add forty one plus the thirty that
I plugged in that gives me seventy one which is pretty close to the seventy-seven calculated
there so that's about the size of a correction capacitor I would need to run on my drill press
and you can see you get pretty dramatic decrease in the DC current by just adding a little bit of
capacitance there so let's go back and take a look at what I was working on with the drill
press kasa just to show you what I'm doing here I've got four pieces of 3/8 inch steel so inch and
a half thick and this is the last of eight 9/16 inch or fourteen millimeter holes I'm drilling
girls pretty good that's all off of solar power and I think it works a little better with that
run capacitors yeah so this is where it gets interesting this is a 18 millimeter bit just shy
of 3/4 inch and drilling down through the inch and a half of Steel so let's see how that goes
that is solar power you just think about it's coming from the Sun down to the panels up on
the roof through the charge controller through the inverter and through this cord back here yes I've
got all my holes drilled we've got 14 millimeter 18 millimeter and those are all drilled in inch
and a half stacks of Steel drilled eight of them at 14 millimeters and then I read rolled five
holes at 18 millimeter it was all done on solar power now my batteries are catching up at pulled
oh one or two percent out of the battery bank because it looks like the drill takes probably
five to seven hundred watts when it's running under load and with 40 amp charge controller
and it's a little later in the afternoon so I'm only getting like 25 or maybe 30 amps of solar
input right now because I'm also running running DC lights I've probably got 15 amps of DC load so
I'm pretty much maxing my solar panels out but the charge controller can't quite keep up with
the inverter running the drill press okay we got the pair of shekels completed have the greasable
bolts in there these are 4100 four-wheel drive pick up a half inch over stock and we have the
anti-rotation tabs that hold the head of the bolt keep it from spinning got the spring eye
bushings for the rear and for the front greasable bolts for the front bushing and ungraceful on the
other shackle shackle hanger bushing so this is a full rebuild kit for rear springs of change
out the bring I bushings and then the shock anger bushings in the frame this is the top and bottom
greasable bolts all around that guy should have a brand new rear spring setup when he gets done
it's time to get this packed up and off to the shipper yeah these were all drilled the holes and
the shackles were drilled with solar power didn't use solar on the lathe I'm not sure if I can run
my lathe off the inverter but everything else was done with solar pretty much just to show you what
I was making when I was doing my drilling tests the other day and this is the completed product
