Hi I'm Angela Busby I'm a trainer here at Stuller and on this segment of How it Works we're going to show you how to size in wax. On this section of the size in wax we're going to go ahead and size up a ring. We're going to size it up rather than down. Of course the same thing you want to do you want to make sure that you inspect your piece want to make sure that your prongs are there all prongs. This one has a lot of prongs so we make sure that they're there and the shank is complete. And the next thing we're going to do is we're going to go ahead and 

take the sprue off of this piece put it on here and see what size this is. So we're at a seven on this one okay and we want to go to a size nine and a half. So we're going to go to our mark a size and we're going to find two and a half which is the number 10 on the mark a size and again you're going to want to go directly at the bottom of the shank and make sure that you're cutting the piece that you need. And for this when we're adding we're going to use this wax and we're going to add two and a half from this wax to this wax so we're going to need that.  And we're going to measure and make sure what our measurements are.  We're at a 2.19 on this one and the thickness of it is a 1.69 so when you're adding wax blank to it we call it a wax blank you can make these using a plain wedding band. Just make a mold of it and get yourself some injections and make sure you're using a little bit bigger than the wax you need that way you can remove a little bit but it's a little harder to add it on. So we're going to measure this when i make sure that's what we need this is a 2.72 by a 1.99 so this will work out perfect for us.  So we're going to cut this one in half because we will be adding and what I like to do is I like to make sure that both sides of it are completely flushed that way when i add the the wax plug or the blank it's going to match up really nice. So the next one is we're going to go ahead and take our mark a size and we're going to cut out the section that we need to add to the wax. So now I know that i'm going to cut this part and then i'm going to cut this part. The reason to flip that wax over is because this this clippers they're going to give you a tapered a little tapered effect on there which is not what you want. So I want a flat on the flat. Ok so now i'm going to put this on my ring mandrel and i'm going to a nine and a half and it is a lot to add. When we're sizing down we basically just use one of these two waxes but because we're going to so big you really want to add the wax to it so that's what we're gonna do. So you want to make sure that your wax is there and we're going to line it up with the the grooved mandrel it's actually a step mandrel and then we're going to take our blue wax our injection wax and we're going to just fill in the edges.  Once you've filled in your edges let it cool for a second and then you can take it off the mandrel.  Looks pretty good now. Be careful that you don't break it when you're taking it off just kind of work it off slow. Ok now we have a size that's a nine and a half I'm going to go ahead and fill in anything that i didn't get while it was on the mandrel. Work in these little edges. And when you size in wax it's not unlike sizing in the metal. It's a little easier to size in wax but basically it's the same principle you're using your mark a size and you're measuring and instead of solder you're using wax of course but it's a very similar. Alright so we'll do the same thing we're going to go ahead and inspect this piece and I'm going to remove the inside of the excess and I'll use my inside file for that the half round. And then i'm going to go ahead and clean it up with the solvent and the felt stick. Working it back and forth I want to get the scratches in the file worked out.  Okay we're done with that. And i'm going to come in on the file the sides. How a lot of people have trouble filing on a wax because it has a tendency to want to dig into the sides of the wax so another way you can do that as if you're comfortable with with an exacto blade and you just kind of remove the wax with that. Just be careful that you're not cutting too much off but it does work a lot quicker. Right here we're going to remove our excess.  Keep your fingers out of the way. And then we're going to come ahead and finish the rest with this. The object of removing the excess is you want it to look like you didn't size in the first place so when you're done with it and you go to finish the piece you'll never be able 

to tell that the ring was actually sized. And whatever work you don't get done in the wax can easily be done in the metal so it would be best to leave a little excess in the wax and remove it in the metal than to remove too much of the wax and then now you have a piece over done when they get it to the metal. And i'm going to come to this buff stick and we're just going to make sure we get the rest of it.  I try to keep a finger behind the wax to have something for the wax to lay on otherwise it's just gonna start bending and flexing and then you're going to end up with a cracked wax and you'll have to start all over. This is about all i would do to it in the wax we're going to leave just a little bit excess that a way they can get to it and then once we add our sprue back on you'll never even know that you had that that little excess. Now we're going to come back with the q-tip and make sure that all of the texture has been removed.  And that is a size in wax up.
