ROSS KELLY: So now, this is a stepped drill bit. Here, want to get a look at it? That let’s you do bigger holes than that what a regular drill bit would do. It steps up in size. It’s not going to be the first drill bit I’m going to use, but that’s how I’ll get the bigger holes.

So, when you used the stepped drill bit, you want to step up first before you get to this big one. You want to start with a pilot hole that will make it so that you can get the other one in there without total mayhem. I’m going to use this fairly large one, but I should rather control this one pretty easily.

So first I’m going to drill the bigger holes.

You get it drilled on right away.

And now my drill battery seems to be dying slightly too but I have another battery with us.

[ROSS KELLY DRILLING HOLES ON THE BACK PANEL OF THE SEQUENTIAL CIRCUITS PROPHET 5]

So there’s our two initial pilot holes for the jacks. Now we’re going to try to step it up.

[ROSS KELLY DRILLING HOLES ON THE BACK PANEL OF THE SEQUENTIAL CIRCUITS PROPHET 5]

So, see how that’s stepping through size by size. You can make the hole bigger. Check that out. This is your initial size hole. This is stepping up in size. Let me just switch my battery and do it the hard way here. Okay. So, we have a 5/8 size hole. Look at this, it tells you what sizes you have, two from the top.

So now we are at --

[ROSS KELLY DRILLING HOLES ON THE BACK PANEL OF THE SEQUENTIAL CIRCUITS PROPHET 5]

All right. There is hole number 1. Let me just go downstairs and grab one of the jacks and make sure it fits.

[ROSS KELLY WORKING HIS WAY DOWNSTAIRS TO FETCH A MIDI JACK]

Lo and behold, and it fits. And then of course I want to make sure that my markings for the other holes are correct. I’m going to drill this hole first so I make sure that everything is cool here.

BILL HOLLAND: Yeah.

ROSS KELLY: Make sure the jacks don’t hit each other. If they do, I’ll drill them out like this if they don’t match up.

[ROSS KELLY DRILLING HOLES ON THE BACK PANEL OF THE SEQUENTIAL CIRCUITS PROPHET 5]

All right. It should be, you know, both holes. Oh, it looks like it’s all working out very well. Today is my lucky day all of the sudden. This should be a metalworking video.

Marking the holes for the next set of holes, which are going to be smaller and hopefully the right size for the hardware. This is the hardware along with these spectacular Dime-O label included with the kit.

BILL HOLLAND: Oh, that’s cute.

ROSS KELLY: I can fortunately fold it in half along the way somewhere. These kind of jacks, these old like sort of style MIDI, 5-pin DIN MIDI jacks, the fixture inside of them is black plastic that’s always loose so even if you screw these jacks in super tight, it always feels like the MIDI cables are going to fall out of them but that’s just the style of these old-school things, and this MIDI kit comes with things that would have what you would have gotten in 1982, 1983, or 1983 from Sequential Circuits.

This is a forceful way of getting the screw up, so even if I screwed it up through a general, not really. All right, we need a slightly bigger drill. I’m going to have to go back downstairs and get what we need here.
