Bespoke Parts On A Rapman 3.1

By David Lewis

BESPOKE: a : custom-made <a bespoke suit>  b : dealing in or producing custom-made articles.

The crew at the DCS Labs have produced the first genuinely bespoke item for the team. While this may seem simple, it is a neat step forward from modding existing designs or making small giveaways. Over the summer I picked up a vintage Mattel Vac-u-Form machine.

The Vac-u-Form lets you create molds by heating a sheet of plastic and then drawing the heated over a model via vacuum. I have wanted one of these since I was 11.

Dead mint and apparently never used

The plastic sheet is heated in a clamping frame and then when pliable, flipped over the mold and vacuum applied to make the mold or part.

A key suggested mod for these is a “cover” that helps speed heating of the plastic & frame. I cut a cover out of sock and tried it out.

I found that the cover got too hot to handle easily, so I asked one of the students (Travis) to design a handle so my fingers would be less blistered.

After a measurement or two, Travis presented me with a design and wanted to try it out on the Rapman. As always, the Rapman, which has been with us for two years now, demonstrated its workhorse capabilities and gave us a decent handle.

I marked the cover, drilled two holes and now have a bespoke enhancement for the lab systems!
