I’ve been in composites for 22 years and have, many times, needed to create a temporary radius during prototyping or indeed when producing tooling and parts. Generally we’d use wax fillets where on an early, cold winters morning it can be a pain to apply even when the shop reaches temperature. Another pain staking effort in the use of plasticine/clay has also been applied, but using this material it’s evident that more time is spent creating good blends to the parent surface.
I’ve recently come across, to me, a new product. A bar of soft wax!
Now using this stuff the edges of the fillet are smooth unlike that of clay or plasticine and the rads are smooth. It can easily be applied in the coldest of temperature just by warming it up in your hands. I just can’t believe I’ve never come across such a product before. I’m sure many of you have used something similar before though.
