Here is one of my lures still in progress , thought that one or another user here might be interrested in that rig .
This is how I furnish the line tie on such "old fashioned" crankbaits , that have their diving bills carved right out of their bodies .
I find this method much better than mounting screweyes under a higher angle against the bill plane , especially when employing multiple tow points ;).
First I would drill three small holes(1,5mm dia.)in line at eyelet location , 90° to the plane , of course through center of blank .
Then I'd take a 1,5 or 2,0mm router bit in my "Dremel" and extend those holes to a slot .
Now I bend stainless steel wire(1,0mm dia.)to shape and furnish a groove on the underside of the diving bill with the "Dremel" , at both ends of that groove I drill holes to accommodate the bent-upward tag ends of the wire form .
Bit by bit I fit in the wire form this way .
When desired fit is achieved , I extend the slots at the bill-side a bit in a "funnel"-like fashion with a conical router bit , this is to create a nice "glue plug" when assembling later .
To glue in the wire form , first place little epoxy glue in either end of the bottom groove , set in wire in accurate position and let cure .
Do not allow glue to flow inside the eyelet slot at this stage !
Then mask the bottom slot with some plastic tape(cable insulation tape works fine) , don't press tape into slot , but leave a small "hump" over it .
Now pour in some more glue from the eyelet side to fill up the entire slot and groove , use a toothpick or wire-piece to work in glue thoroughly without airbubbles .
After 24 hrs. curing all excess glue can be removed with the "Dremel" , with a carpet knife and by filing/sanding:).
