Ready Steady Eddy

[EddyCurrent]

Reactive Resins Syntac EPAFD epoxy with Synamin 201-c slow hardener.

This was the starting point using shims to level up the linear rail support beams.



A test piece was made using a 50x50 offcut, epoxy resin, draught excluder moat, http://www.toolstation.com/shop/Iron.../sd2802/p70101

Temperature 17 deg C
Used kitchen digital scales to measure out by weight.
Mixed in a plastic cup, no melting of cup, no heat felt but it was only a very small amount.

Just after pouring, the viscosity was very good for pouring, it seemed to be runnier once the hardener had been added and mixed.



You can see surface bubbles, I dragged a tooth pick/cocktail stick through the epoxy a few times and bubbles dispersed.
Next time I will mix the two parts more slowly so as not to introduce so much air.



The viscosity was such that 2 hours later the remains in the plastic cup could still move like a thick fluid.
Slight leakage occurred at draught excluder butt joints e.g. corners, so I will be using a dab of glue at these points.

Following day about 20 hours after pouring.



Depth of epoxy = 5mm
Draught excluder removed with a chisel no problem but it left a slight sticky residue that cleaned up okay with spirits and the epoxy captured a very small amount of foam in it's outer skin.
A slight meniscus can be seen but this was expected, 'Clive S' describes how best to remove this.
The epoxy is fairly hard but you can tell it has a day or two to go until it's cured.

I would say this test was a success and I have no problem with using this on the machine.
