I heard him about halfway done making
the hoops for my raised beds that I'm
going to put some rope cover over this
legs already been done and you can see
it works out pretty nicely
and these hoops are made out of
half-inch conduit and they fit right
into the beds I just custom-made the
bend on there and that's why I'm going
to show you how to do today and I did it
for free with some scrap material so the
first thing was my beds are about 46
inches from the inside to the inside
walls there so when you make your jig
for this it's 1/2 inch conduit so
there's a half inch given up on each
side so you actually want the inside of
the curve to be a 45 inch curve which
means a 22 and a half inch radius of
curvature for the bed I also have about
six inches of straight tubing down at
the bottom there where it's going to go
into the ground so the curve starts even
with the top of the bed and as you can
see it turned out pretty well all the
hoops are fairly uniform and look clean
so this fabric is working quite well
keeps the dogs out and idear out and the
kids and the bugs and the wind from
destroying my garden so I'm hoping to
finish out last few hoops down here and
I'll show you how I did it okay so
here's the jig for bending the half inch
conduit for my hoops and I put down a
nail in the middle here for my pivot
point tied a string to it I cut the
string already we put a pencil on it and
then just measured out from here all the
way to the first nail this one to be my
distance that I want for my radius since
I want it to be about 45 all the way
across for the inside of my curve so I
took half that for 22 and a half inches
to this first nail I put it about two
inches or so away from the end same with
the the pivot point here I put about a
couple inches on the end and then I did
all the way over here take your string
and then just swing a big arc all the
way across the top there and pencil it
out then I just took a bunch of wood
screws a couple inches long just drill
them right through this old piece of sub
that I had laying around made an arc out
of the screws left them about an inch
tall or so and then on the starting side
here I screw down a 2x4 and I had an
extend about six inches from here to
here to give me the straight part for my
hoops that will go on the ground so to
use it basically just stick the piece of
conduit in to about here so that lines
up just down the tunnel and then grab
the end and then just start bending it
around the curve until you come out to
this side and then if you have any extra
over here just cut it off at about six
inches I did have a piece of wood over
on this side but it was kind of a pain
to get to lock in there and had to fight
the metal the screws do get bent up a
little bit and I would recommend having
a lot of screws at the beginning because
it takes a good bit of the force and
they do kind of get bent up it doesn't
work very well with three-quarter inch
or inch conduit it's justice to hard to
bend it'll Bend and screws over from
what I've tried so it works with
half-inch but not with the thicker stuff
that I've tried
