Hey Barb!

..... can you tell what it is yet?

Just an early test, still a month or two away from production.

Progress in polyurethane!

The biggest limitation I've faced with moulding polyurethane components has been bubbles of gas trapped in the finished components. This has meant quite a high reject rate, itself a big issue with a labour intensive process using expensive materials, while other products which couldn't be successfully moulded at all.

Once the polymers are mixed, they need to be placed under a high vacuum to extract gas from the mix, before it starts to cure. A recent upgrades to a larger vacuum pump has allowed me to cast parts which I had previously considered impossible.

The seat block moulds were made last year, but initial testing was unsuccessful and they were put aside. Looks like they're now a viable product......
