00:00:09two-by-fours ready because my 4-foot
00:00:11magnifying lens needs a sturdy frame i
00:00:13hack this out of an old TV in a previous
00:00:15video but it’s too flimsy to use on its
00:00:17own we need something that’s super cheap
00:00:19to make but sturdy and easy to use and
00:00:22I’ve got an idea that just might work
00:00:26[Music]
00:00:39measuring the size of the lens seems
00:00:41like a good place to start so let’s do
00:00:43that and then mark the wood for custom
00:00:45cutting it’s best to use as little wood
00:00:47as possible so I’m going to use this
00:00:49table saw to rip these studs into this
00:00:51shouldn’t compromise the integrity of
00:00:52the frame at all and it will cut the
00:00:54weight in half these two by fours are
00:00:56now two by twos and will need to cut a
00:00:58group right down the middle once I’ve
00:01:00got the centre lined up I’ll lower the
00:01:02blade down to about three-quarters of an
00:01:03inch
00:01:04and get the saw spinning as the beam
00:01:06glides over the blade I’m happy to see
00:01:08that it cut the clean 3/16 inch groove
00:01:10this is the groove that our lens will
00:01:12fit into and sliding the pieces together
00:01:14into place proves that the cuts were
00:01:15good the edges match up and the frame
00:01:18looks functional but before we secure it
00:01:20we’ll need to drill some holes right in
00:01:22the center to accommodate this three
00:01:23inch bolt I’ve added a rubber washer to
00:01:25the bolt and pushed it through the hole
00:01:27then when this piece goes back in place
00:01:29we can still access the threads whoops I
00:01:31almost forgot I wanted to add a more
00:01:33finished look to this frame so I’ll add
00:01:35a half inch a per bit to my router and
00:01:37trim the outer edges
00:01:38I built this router right into my
00:01:40workbench so I have a lot of room for
00:01:41bigger projects look for how to build
00:01:44this router table in a different project
00:01:45these simple cuts are quickly giving the
00:01:48frame a more professional look okay
00:01:50those are done so now I can retract my
00:01:52router bit and lay these support blocks
00:01:54down the lens goes over top and these
00:01:56blocks are helping prevent the lens from
00:01:58warping when we’ve got one of the
00:02:00corners lined up we can drill a pilot
00:02:01hole and add a three-inch wood screw
00:02:03that’s holding well so let’s repeat that
00:02:05on the other three corners drilling
00:02:07these holes first helps prevent the wood
00:02:09from splitting when the screws go in the
00:02:11scorcher lens is framed and we can put
00:02:13that off to the side and get to work on
00:02:15making a collapsible a-frame this time
00:02:17we’ll need to cut to 5 foot lengths of
00:02:192×4 and rip them into two by twos the
00:02:21same as the others
00:02:22I want to make a hinged frame but before
00:02:24we do let’s router these edges as well
00:02:26and save some of the sawdust for a
00:02:28future charcoal making project all right
00:02:31my table is clean again and I’m going to
00:02:32try an idea for a modified hinge with
00:02:34these eye screws these screws were six
00:02:36for a buck and will only need four holes
00:02:39are drilled in the center of the
00:02:40chamfered edge and then these screws are
00:02:42tightened to where they line up nicely
00:02:43with each other they stay together
00:02:45closed and fully open so I’m hopeful
00:02:47this is going to work it’s time to join
00:02:50the a frame with the scorcher lens a
00:02:52washer and nut go on the bolt and now
00:02:54I’m cutting this barbed sprinkler line
00:02:56coupling to act as a spacer the barbed
00:02:58is on with a washer on either end and
00:03:00the eye screws are added next followed
00:03:02by a washer barbed washer and secure it
00:03:06in place with a wing nut everything is
00:03:08duplicated on the other side and these
00:03:10frame legs pivot just the way I was
00:03:11hoping next we’ll need to measure the
00:03:13distance between the legs and cut four
00:03:15more pieces of wood to act as support
00:03:17braces when those are roughed in place
00:03:19let’s measure about 10 inches from the
00:03:21scorcher frame and make some marks when
00:03:23we’ve drilled the holes and added the
00:03:25screws the frame is pretty much done the
00:03:27scorcher lens rotates a full 360 degrees
00:03:30and seems relatively sturdy one more
00:03:33thing I want to try is adding an
00:03:34adjustable tensioner so I’m cutting a
00:03:36scrap piece of 8-inch cardboard into a
00:03:38strip about two inches wide and 18
00:03:40inches long then I’ll adjust the saw to
00:03:42cut a groove in the center stopping
00:03:44about one and a half inches from the
00:03:45ends a hole is drilled in the frame ten
00:03:48inches from the top and the band is
00:03:49connected to the frame with a three inch
00:03:51bolt and some wide metal washers a wing
00:03:54nut will hold that together loosely then
00:03:55this other end of the strap connects to
00:03:57the side of the pivoting frame about
00:03:59five inches from the fulcrum loop steps
00:04:01a little too tight so I’ll back it off a
00:04:02touch and give it a test
00:04:04I can still rotate the lens nearly 360
00:04:07degrees but now I have the benefit of
00:04:08being able to position and
00:04:10securely at any angle I want the frame
00:04:13looks great and totally exceeds my
00:04:15expectations for functionality and
00:04:16practical use the best part is we made
00:04:19the whole thing custom for about eight
00:04:20dollars that’s it for now if you like
00:04:23this project perhaps you’ll like some of
00:04:24my others check them out at the king of
