Epoxy pouring advice

[cncJim]

From my experience, epoxy won't stick the the non sticky side of duct tape. I think it will definitely stick to the sticky side. I wrap duct tape around wooden blocks and use them when clamping epoxy glue-ups, so they don't get stuck to the work.

Thanks for the tip! Odd thing is the guy in the video uses the blue tape with the sticky side against the epoxy. The way he describes it in the video makes me think this is also true for duct tape?

Good video Jim.
I think he means blue masking tape. The priming idea looks to be worthwhile, I would most likely have used that method, I don't think it would have reduced the meniscus but anyway in practice it is so easily removed it's not worth fretting over.

I think I will use the priming idea when I come to it, seems like a good way to avoid leakages. I guess if the width of the epoxy is large enough it doesn't matter if the meniscus is removed or not?

Epoxy doesn't stick to the non sticky side of cellotape. Line any channel walls with that.

Thanks Charles, good to know

Nope it sticks to duct tape. Well mine did at least.

And you would want to remove it. After you take the tape off you can be left with some seriously sharp edges. Just get a sanding disk on a drill and go around all edges. Took me about an hour for about 18 meters worth of edge

Jim, it's easy to do a small test first, you could use different tapes to find the best one, pvc electrical tape might be another option ?

That is true but honestly it only takes a few minutes to level it off with a good file, having said that I've had a lot of practice with a file.

Good idea, I will give this a go before attempting the rails.

Well, you make it sound easy enough, I will need to buy a file first!!!
