Working With Metal Continued
I'll be using three hinges to hang this gate, which
should work pretty good. These hinges are meant to be welded on but this
won't work for my application because I need one side to have holes for
some
screws.
|
|
 |
I used my milling machine to put three
holes on one side of all the hinges, which was easy to do.
|
|
 |
I made the chamfers larger enough to use some #12 screws because those
will be going into some wood. I wanted to make sure the gate was
fastened really well because it's pretty heavy.
|
|
 |
|
I placed the gate at an angle so I could weld the other
side of the hinges. This worked out well, and to make sure the gate
didn't move I used those same Kant-Twist clamps on the saw horses to
keep everything in place.
|
|
 |
Here is one of the hinges tack welded and is now ready to be nailed in
place.

My son-in-law is going to use a large magnetic lock to
keep this gate closed. That means he'll need a place for the mag-lock to
make contact so I'm going to make a piece for that. This is 1/4" thick X
5" wide cold rolled steel that should work great for this. And I'll be
making two other pieces as well.
|
|
 |
|
The piece for the mag-lock is on the right and is 8"
long. I drilled six 3/16" diameter holes on one side because this will
be screwed to the square tubing using 10-32 screws and will be placed in
the center of the gate. The other two pieces will be placed above and below the
center of the gate and will act as 'stops' so people can't flex said
gate. And again these two pieces will be screwed in place.
|
|
 |
The machined area is for the mag-lock. A machined surface holds a
magnet better than the 'scale' of the cold rolled steel surface. This is a
clean-up cut and is only .020" deep.

Here is the opening where the gate will go. My son-in-law built the
walls that you see here. And if you look close, you can see the floor is
actually round. 12 foot in diameter to be exact. Let me explain: this
room was used as a magician act for about 1 1/2 years, but after the act
closed down at the end of 2024, this space was just sitting. So the kids
decided to use it for this new game.
I mentioned that the floor is round. Well the magician
act had his audience sitting on benches in this round area and as he was
performing, he would stop, turn the floor 90 degrees and then do another
act. This went on for all four positions and then when the act was
finished, the audience would exit the room.

Back to the gate installation. At this point, the gate is installed and I'm getting ready to
mount the plate for the mag-lock. While the plate is clamped in place,
I'm using a transfer punch to produce a small center punch on the frame of
the gate. This would give me the location of the six holes. Next I drilled and tapped for six 10-32 screws. I also mounted
the two other smaller plates, one was six inches from the top and the
other was six inches from the bottom of the gate.
