Hello everyone welcome back to PJ Chen Design. Today we gonna model a clock and
actually prototype through laser-cut and construct it together. So I will show
you all my process of getting these things from the computer model to
actually prototype. Let's get started!
first of all you need to get your parts. I Bought my on the Amazon. I just type it
"clock parts" and then so it comes in all different kinds. What I'm looking at here
is the hands. What is hour hands and the minutes hand, and if you want to have
a second hands. So the mechanics in the back is pretty much the same. It's just
you want to pick up the hand that you like. The one that I got is this one. It is
31 mm long shelf, and I didn't know how much is the
material that I wanted to start with, so I bought this one, but it end up a little
bit too long so you probably want to have your design ready, and then get your
part from the Amazon or other places that you can get local or online. Once you
have the part, and I will suggest you actually to model the parts. so what we
wanted to do is measure overall the box and also the hand length, so when you do
the design this will be the guide line. And most importantly, we need to measure
the diameter of the shaft there, so we know that how big of a hole we need
to punch on our design. So once you model it. They don't have to be super
elaborated. It's just for us to do the model to build something on that. so once
you have it, you will just lock it, and into to our design. First of all, we're
gonna throw a circle, and then we will know like how big is the hole that we
need to cut out. I'm starting with the oval command, and I'm gonna start at
something right here for my first one. I'm going to use the command that's
called Polar Array. In the center, just type "0", and I need eight of them
doing 360 degree, and I got something like that. Okay so then
next step, I'm going to make something a little bit bigger by copying this one
first. Make it a little bit bigger, and let's moving a little bit, and also
rotated 22.5 degree.So they will locate it right in the middle. If you like the
location, let's go ahead to do the polar array one more time, and we want to do
eight of them as well. So after you have done that, we are going to move one out a
little bit. Make a copy, so it's kind of repetition form.
So what we are going to do with this is I want them to be twist a little bit. The
command is called "Maelstrom" and then what it does is we can set it up this
Center and then tell it like where do you want it to start to twist, so I
want to twist in between here, so I can do something like this. Okay and depends
on the area you set it up. Let's say if I
set it up in between here and all the way here, so most of the thing within
this area well be twisted. so that's how I get this form, and then you're just creating
the outline after that. so once I finish what I like, and I just need to copy into
the smaller or bigger to get three different size. and I wanted to have my
clock as twelve by twelve (inch) so this is the line that we are ready to send for the
laser cut. Let's take a look on the laser cut process.
okay after laser cut, we will need to spray paint. You might need to have
several coats on that, and this is the entire package that we're going to put
it together. If you model it correct the hole and everything is really accurate,
then you shouldn't have problem assembly. and then they should come out really
well. so follow the instruction that you have a washer tight it up. You might need
to get a wrench to tight it. so you put the hour hand first, and then you put the minute
hands. Some of it coming into the 13 so this is the prototype process for this
laser cut clock. I hope you enjoy it. Please like and comment and let me know
what other things you would like to see. I'll try to do my best to make the videos.
Thank you and I'll see you next!
