Barney’s Handle

Barney’s Handle

Barney’s, a local brewery residing at the Summerhall wanted an original beer tap handle to celebrate the launch of a new product.
Barney wanted to do something interesting with a miniature of his truck. The idea of a beer handle sounded fun.

The weight of the resin combined with the way such items are handled generates a lot of stress at its anchor point therefor more suitable for decoration rather than functionality. If there was a redo, would machine a much wider threaded base with a rode going through the whole handle. An other idea would have been to make a badge (found in front of the tap) with the miniature, perhaps splitted in half, instead of the handle for a more functional approach.

Casting like this can be challenging to be bubble free.
First, inject whatever you are going to cast with the resin so that no air can get trapped on the model when pouring.
Second, vacuum degassing is paramount. Ideally, you want a relatively long “pot”* time so that you can fully degases the mix before pouring. It can take some time depending of the viscosity, should ideally over 45min.

* The term “pot time” (or “pot life”) refers to the amount of time a mixed material, like resin, remains workable before it starts to harden. After mixing, resins (like epoxy or polyurethane) undergo a chemical reaction that gradually makes them more viscous. During the pot time, the material can be easily poured, applied, or shaped.
