I've got an idea for a project where I want to drill some holes like this at a 45-degree angle
using this square jig drill two of those in fact so the problem is I'd need to somehow raise this
up on some raised platform or I could just hold it like that and then it's easy enough to move
the fence to position those two holes so I need some kind of 45 degrees support that I can mount
and clamp the piece of 2x4 to and I figure I'll make it out of this plywood I haven't
really got much of a plan for this though I think I can trust this to be square now now
I just need to cut this at exactly 45 degrees I was using this little scrap as a hold down like
so and it's tilted downwards and then when I clamp against here that wants to pivot down even further
which presses the clamp down on here you know I know this forms a square with them like that
but let's test a 45 degree nature of this by flipping this around and that will reverse the
error on this one essentially doubling my total error oh not good you see that I'm open by about
a millimeter up here hmm so now I need to take a tiny bit off of this side here and then I'll
test again so I've got the same angle error here and if I trimmed it like that they would
add up to 90 degrees but I want to trim half as much because I need to correct half the error on
each triangle so let's see if I put that like that okay that is too much spacer so with it like this
so this is still perfectly square and this okay I still have a tiny
bit of error here I think I'll try to fix that with a belt sander
no I think that's close enough yeah good enough
these notches are so that I'll be able to clone up through here these two holes are for clamping
it to a table and then this one is for clamping it together while I'm gluing it and I made these
holes relatively small because I've got these key slot clamps that sit in here I didn't pay
for these these were sent to me for free by micro jig I did however pay for this Festool clamp I
think he cost about the same as these ones here so micro jigs are quite expensive that can also
be used and the cheaper alternative is this thing which is for sacrificial fences or I could have
just made the hole a little bit bigger and then these clamps would fit in there I always think
it might be good idea to leave the glue sitting on the end great for a minute before clamping
it so that I can soak in a bit better and not starve the glue joint after I clamp it together
oh I think this might be long enough now so I'm attaching this with flaps only for now
I just realized this thing also needs a bottom down here because otherwise if I drop it say on
to this corner here that'll just bust that right off whereas if I have a bottom in here that'll
stiffen it up but these holes are too close to the edge so I need to cut out a bit of a
notch two of them into here to provide room for the clamps I'll try that on the bandsaw
I have from time to time meld into some of my jigs by accent which is
why I am reinforcing it with Donald's nut screws
but for the bottom it doesn't really matter so I'm using screws there I realized I need a fence
on this thing and I want that to be removable so I have to use screws on the top after all
you got my jig clamped down with our workpiece on it and it's taking a bit of fiddling around
to line up this fence so that I get two holes that are consistently spaced from the edges
pushing into a drill like that makes me appreciate a drill threatened war
this could use some more roundish edges
I made this jig for drilling 45-degree holes in the ends of these pieces of wood to try out a
table leg apron joint like this so this is the leg that's the apron and I might add another
piece in here just for extra reinforcement but this is not without a snag because it turns out
the holes in here are a little bit crooked you can see here it's not at a right angle and if I did I
mess up with my jig but I think what's happening is as the drill digs in here it probably digs in
more on the top side where the grain is kind of coming into the drill then on the bottom side
we should force the drill overall to wander to the left and that is indeed the direction
that it wandered in it went this way that's a challenge with drilling in at an angle is the
wood grain can mess with your drill so the next time in addition to shoving your drill really
hard this way you have to make sure it doesn't go this way on the front so a more logical thing
would be to have a fence on the front or just flip this whole thing around put the
45 degree jig on this side and then the turning of the drill will push it against the fence here
