Radio Knob Mold - Silicone Mold Making - Squirreland

Today I made a simple silicone mold of a vintage radio knob. Some molds that I make are odd shapes and it would be very difficult to measure the exact amount of silicone needed to mix so I can complete that particular mold. When I pour silicone for a project in my shop, I generally have one or two smaller molds nearby in which to pour any excess silicone. Silicone is expensive and there is no reason to waste any because I mixed too much. Since it is already mixed with the hardener and is going to eventually cure, I might as well have some smaller useful molds on standby. This is one of those molds.

Can you do a video on how to install the knob insert (bushing) and set screw?

[@squirreland]

I make Halloween decorations, not radio replicas.

[@stephenpascoe1148]

What did you use for insert (brass/moulding?) to attach to splined shaft?

[@squirreland]

It's just meant to be a decoration, it's not meant to be functional or a replacement for an actual radio knob.

[@ThisIsJessPaul]

Perfect!

[@n9amiwavelengthradio]

What about the back???

[@squirreland]

It's only meant to be decorative for prop builds.

What kind of resine did you use? 😊

[@squirreland]

West System 105 Epoxy Resin with the 206 Slow Hardener and black resin pigment from the hardware store.

Another question, did you use vaseline to do the molde?

[@squirreland]

Don't touch that dial, because we'll be right back after these messages!
