I make and open face silicone mold to cast some rubber feet for my Subwoofer.
I cover how to make the open face mold and then use urethane resin to make squishy rubber feet in the mold.

Every time I watch silicone being degassed it amazes me. I would have never thought that much air gets trapped inside.

Another great video showing the process Eric. Glad to see our ColorFlex CF-80AM is working out well for your molded parts. We love the range of colors you can achieve with that system and it even does well in applications with UV exposure. We have parts outside for almost a year and they are still working well.

Of all your videos I have viewed this would be my favorite. You took a real world problem, and solved it using your skill and your tools. The same thing I love to do every day. It doesn’t have to be a big complicated problem or a big complicated solution, it just has to work at the end of the day.

I use a small Bluetooth speaker that has a sub facing down and it was constantly rattling everything in my shop, I made a "disk" of silicone to put under the speaker and it helped in a very similar way. Great video as always Eric!

After pouring resin and hardner in mold, does this mixed need to be heated to dry? I mean exactly that it wouldent dry by itself in home temperature and pressure? Thanks indeed

@EricStrebel 3 ай бұрын

It's a chemical reaction heat only assists in the curing

3 days ago I made a small casting using Alumilite Flex 80, with a 1:1 ratio based on weight. It never cured. It remained gooey for > 24 hours. Could it have been affected by the frigid temps of my workspace? After I exposed it to a space heater for several hours, it firmed up a little, but stil crumbled in my fingers when I tried to demold.

Nicee. What do you use to color the urethane?

@EricStrebel 2 жыл бұрын

Black pigment, so the part is opaque, as opposed to a dye that is translucent

Sorry to sound so stupid but I am very new to casting, when you refer to "PVA glue" in all your videos you mean the Elmer's right? (What you put on the bottom of the plastic foot to stick to the cup)

@@padel24x7 For example, the elasticity depends on temperature. You'd also need to print it with a fairly high infill, as it would otherwise collapse from the weight. And you can't really recreate the same dampening characteristics with 3D printing, unless you go for 100% infill, and even then it is probably going to be too stiff to do a good job decoupling the speaker from the floor.

That’s a lot a faffing about to ruin a perfectly good subwoofer!

@baudgaud 2 жыл бұрын

I had a similar thought. Not sure what rubber feet will do that setting it on a rug will not do, except that setting it on a rug is undo-able for when your wife is out of the house and you want to remember what it was like to have a great subwoofer.

@baudgaud 2 жыл бұрын

@@officialWWM Perhaps your experience is much different than mine, but it is quite difficult to find a woman who I can put up with who can also put up with me. Everybody has their quirks. My point is mostly that, while it is very cool that the presenter shows how to make a mold from an existing part (complete with naming the products involved) and then using that to cast a new part the same size and shape (again with the full materials list), I do not believe swapping plastic for rubber feet would have ANY dampening effect on a subwoofer! I can believe that the hard-plastic feet rattle on the floor every time the bass hits, and that should wreck the quality of the woofer sound for an audiophile as much as for an annoyed SO... and we can see at the end that he does set the box on a hard tiled floor. If that were the case, why did the presenter blame his wife?! So I can not understand "the bass is too loud" being corrected by changing the feet. It seems as sensible as getting a haircut in response to a broken bone.
