Yes it's on concrete, but only for like 15 minutes to hold the material until the glue got tacky.
2.5 bottles of silicone to bond the top to the mold
0.5 bottle for the low spots
It's still drying in my car.. fumes from the silicone and all!
While that was drying, I started making some terminals. The cheapest price online was like 1.80 for 1. There were bulk deals, but I don't need 100 of them. I made 31 in all- +9/16" inner diameter, 1 7/8" length, flared end. I was bored so I made like 4 kinds. The one on the very right is a mix of the left and middle one. Haha again, I was bored.
Test shows it fits like a glove!
I forgot to mention that I plan on rounding off those corners on the terminals when I drill the holes, but I'm tired now.
