Good Luck Guy

Matt gave a lot of excellent advice here.
And for free too!

The only place I would offer a differing opinion is the mixing pumps.
I've used them and come to not trust them.

I think they are too wasteful - besides being too expensive.

Instead, I'd suggest the use of syringes.

I buy mine at Tractor Supply, but almost any farm supply or Vet store
will have them.

For West Fast (5:1 ratio), I use a 60cc for resin (pulled to the 50
line) and a 10cc for catalist.

For West Slow or Epiglass (3:1) a 60 and 20 - and just count (OUT LOUD)
the shots.

FWIW...

You were doing great until you gave the wrong ratio for "West Slow".
West System has different hardners for different uses, (including one
called SLOW) and they all mix 5:1. West specifically warns aginst
varying the ratio to try and modify the cure times, as it also
negatively affects the final product properties and quality.

You can play with temperature changes to some degree to hasten or
retard the cure rate.

Sorry, Dog, I got confused.
That happens sometimes before coffee takes effect.

207 and 209 are 3:1, the rest, including 206 Slow are 5:1

It's 99 to 105 outside in the shop.
206 seems to gell in 10 minutes.

I'm using 209 and trying to get done in 15 - 20 minutes.
'Cuz after that, it's not gonna go...
