gliders

Yip,some think adding say 2 grams topcoat is like adding 2 grams lead !,it ain't. If you were to take say a metal spoon or lead jig and keep adding layers of epoxy ,it would gradually make its sink slower due to decreasing weight to volume.

Copper foil tape under epoxy after 18 months, no change. Foil can be a lot smoother over smooth surface,this one shows woodgrain and was made in a hurry for a particular trip but shows foil as shiny as day it was done.

copper tape I use is much like venture tape but slightly heavier, have it on glider pattern that has been used for year and a half. Copper still shiny as day it was made, will post picture of finish if useful when I get chance.

Fishon son,i use copper tape sold for guitar pick ups with no problem at all, fix to lure,wipe with alcohol, coat epoxy,no issues with tarnishing or adhesion and fairly easy to use. Bit heavier than aluminium and not tried on small lures ,but nice effect and user friendly.

Got to be blank expanding in heat surely.

Jon, paint a blank white and epoxy over, practice on that then wipe clean to use again.

There you have it jon, both types of construction work well if done properly, it may come down to whatever building process and material you are using . Try using both to build a few lures to completion including painting and top coat. You'll get a better idea what to go with - I.e - time, effort, cost, pro's and cons for rest of build. Oh, and test for strength yourself for peace of mind! Regarding dales thunderstick, certain types of builds can obviously sometime dictate what you use, for example making the tail section of a thunderstick would pretty much demand through wire, would be silly to use anything else, however you asked are screw eyes strong enough- yes! Would through wire be better in resin? Build some and see.

Yip travis and mark,I use 40mm screw eyes, sometimes twisted wire, epoxied in,never pulling out. I've also seen screw eye's loosen slightly due to torque/fish twisting when unhooking at side of boat or in net, only a few times and not with my lures I might add.I have experimented with flattening or grinding flats on screw eyes, and it makes them very resistant to twisting, but a bit of a pain to do and integrity of metal shank a worry. If made that way it could be an improvement though.

Always thought screw eye's should have flattened shank to resist torque.

Jon, if you paint first with pearlescent base colour then transparent colours, you can get nice deep effects.
