It's been awhile but I used JRHopkins method. Once you fan out the brush fibers, I applied painters tape to the fanned out portion of the fin or tail to hold it all in position then I used epoxy to glue the base together. Let cure. Then later epoxy the fin/tail into a slot in the lure. Let cure. Trim to shape.
I have mine in a room… door always closed and window always open…
I have read a lot about temps… but I never had to worry about it…
Once I found my optimal settings, I have been getting the same results in the winter (even printing at night) and in the summer…
I always use anycubic standard in grey.
I've only done one, so I'm nowhere near an expert. I used the brush for fins, not the tail on this one, but I'd assume it's a similar process. I used an old paintbrush and used superglue to install it. I trimmed mine after installation.
I think The engineered angler has a really good technique. He takes an old paint brush spreads it out covers both sides with masking take, cuts it to shape then glues it in. I plan on experimenting with these types of tails soon and that’s what I am going to follow.
