How To Make Your Own Gobo

By | 08/08/2022

How-do-you-do anybody! As promised, Here is the article on how to make your own gobos (a gobo? what the heck is that?)

Well hither’s what we’ll exist edifice in a youtube video:

Recipie for 2 Gobos:

cost:

about $xl per gobo

note:


Each step covers what to exercise for one gobo. You lot need to do the instructions from step 3 – 12 twice to complete both gobos.


Ingredients
:

  • 16 feet of 1×12 lumber
  • 12 feet of 2×4 lumber
  • two – handles (I used cabinet handles)
  • Box of ii” wood screws
  • Fiberglass insulation
  • 2 – 2′ x 2′ pieces of 1/four” plywood
  • A encompass for the absorbent side of the gobo


I used pegboard for my absorptive side. I evens out the frequency response a bit, if y’all’re non sure what that means, my advice is to use pegboard. If you
want
your gobo to absorb lots of high frequencies the you can staple canvas around the open up side of the gobo instead.

You tin as well make encounter through gobo’southward past removing the plywood, fiberglass, and absorptive side cover from the list. Use 2 – 2′ x two’ pieces of plexiglas on both sides instead of plywood and an absorbent embrace.

See through gobos are useful when y’all need several gobos to block the sound and y’all want to stack them without breaking the musician’s eye contact.

Tools:

  • Round Saw
  • Drill (with a 3/32″ bit; A screwdriver bit would also be useful)
  • Measuring Tape
  • Screwdrivers
  • Pencils
  • T – Square
  • Boxcutter

Step 1: Cut the pieces yous’ll need

I labeled the dimensions of each slice equally I cut it:

  • (2x) 2×2 ane/4″ plywood
  • (2x) 2×2 pegboard
  • (4x) 2′ long 1×12
  • (4x) 1′ nine” long 1×12
  • (4x) 2′ long 2×4
  • (4x) 8″ long 2×4

Step 2: Mark the 2′ long 1×12’s ii.5″ from each end. These marks evidence y’all where to drill later on on.

Pace 3: Fix the 4 sides of the box on a apartment surface and tape them together. The two’ long sides are shown on the left and right in the picture, and the one’ix” sides are shown on the elevation and bottom in the picture beneath.

Stride 4: Drill at the places you marked, and try to make sure that the yous get the bit centered past the width of the 1’nine” pieces. Yous should cease up with 8 holes (2 on each corner). Put a screw in each hole.

The four pieces should make a perfect square with 90 degree corners. Use the T – Square to cheque this is the case every bit you lot go.

Pace 5: Put the 2′ 10 ii’ piece of plywood over information technology (it should line up with the edges of the box you lot’ve built so far). I didn’t need to drill holes before putting in these screws, but if y’all’re worries near it, or using really fatty/long screws, it may be a good thought.

Pace 6: Now that the box is strong and stable, you tin can pull off the tape we put on in Pace three

Footstep 7: Attach the handle. You want to center the handle so that it’ll fit nice afterward on. The terminate goal is to have information technology fit between the feet of the gobo above information technology so that they can exist stacked easily.

In this moving-picture show, the long 2×4’s on either side of the center row (the one with the handle and the shorter 2×4’south) represent the positions of the anxiety of another gobo. Don’t attach these long pieces, they’re only to help yous understand.

Before yous attach the handle marking where the holes need to exist drilled by putting the handle on information technology’due south side. Drill from meridian to bottom through the marks you lot merely made. And then it’s a piece of cake to attach the handle using the screws that come with it (all the handles at Loews came with screws)

Step 8: Cutting the fiberglass insulation into 22″ segments. If y’all used fifteen” wide RC-13 like me, you’ll demand six segments per gobo.

Cut 2 of the half-dozen segments in half (as pictured).
Only cutting ii of them in half.

Here’s what all your cutting fiberglass should look like:

Footstep 9: Put the fiberglass segments in the gobo facing out (each layer facing out, though it doesn’t matter a whole lot which way the individual pieces are facing).

Footstep 10: Adhere your embrace. I used pegboard because of information technology’due south flatter frequency response. Yous tin can apply sheet if you’d like to tame those higher frequencies, or if y’all but desire to block audio with minimal absorption simply put plywood on this side equally well.

note: in that location is no insulation in the movie. This is just considering I’one thousand dumb and took the motion-picture show at the wrong time ;).
Don’t have the fiberglass dorsum out of the box.

Footstep xi: Attach the feet. The anxiety are necessary to make the gobo’s stackable. Once again, I didn’t need to drill before putting in these screws. Yet I did demand to put the screw in, take it out halfway, and put it in over again (to get a tighter fit).

Whatever yous do, simply brand sure yous put the screws in far plenty that they’re somewhat inset into the 2×4. Yous don’t desire the screw sticking out, or else it’ll be wobbly and besides scratch wood and tile floors.

Proceed in mind that these need to exist all the way to the edges, because the handle and alignment 2×4’due south need to fit in betwixt them.

Step 12: Attach the alignment 2×4’s on the meridian.

Sorry to utilise the same moving-picture show twice, simply this one is the best shot to illustrate the bespeak. You desire to attach these alignment 2×4’south so that they’re in line with the handle with space for the feet of the next gobo, which would exist on top of it.

Steps thirteen – xv: Admire your handiwork!


I hope you lot found this howto guide useful! I’ve also created an instructable of this guide.
