Excal Coil Mod..

[mtpockets]

Can someone who "Owns" a E Trac Or SE measure their coil bolt. and tell me what size
it is..

I sold My SE otherwise I'd be able to do it myself..

I mainly water hunt now. and have 2 Excals.

But, I'm tired of the Sloppy loose coil syndrome... I put new Tear drops in every couple of hunts and it's getting old.

****ALSO****

I'm looking to see if I can drill the holes on the Coil itself just a little bigger to accommodate the SE Coil Bolts.. The holes in the Excal shaft are 9/32 and I'm hoping the bolts to the SE are the same..

Has anyone made their coil holes larger? I don't think that by doing so will jeopardize the

the coil any..


As it stands, the Standard coil Bolt and coil holes for the Excal is 1/4" ..

The Excal shaft is 9/32" so I'm wanting to drill the coil 9/32"

LOL.. I hope I wrote this in a way for everyone to understand.

The Whites have a much bigger bolt than the Minelabs, which seems odd since Minelab coils tend to be heavier. I think I ended up using a 1/4" nylon bolt and nut on my custom GT shaft with Whites lower rod. It fits the Minelab coils without drilling, but is smaller than the normal Whites bolt. You could drill out your coil holes to use a larger bolt but I see no need for that. As for washers, go to Home Depot and look in the sink repair section. They sell rubber washers that will fit fine, though you'll need to drill out the washer's hole a bit. I'm using two of those along with two Whites rubber washers to span the wider gap that a GT coil has than my White's lower Tall Man rod.

Works fine, although bumping it with my foot will cause the coil to wiggle for a split second as the rubber flexes. Probably be a better idea to put a plastic washer beside the stock Whites rubber ones. Less rubber to flex, but it's still very stiff as is and I think of it as a "shock absorber" in case I hit a rock or something. Better to have the shock absorbed at the rubber than transmitted up the shaft. Coil is still stiff and rigid regardless.

You can find these nylon bolts and nuts at hobby stores. Many RC plane builders use them to attach wings to the fuse. They'll even boil the bolts in hot water to make them more brittle. That way when you wreck the wing bolts will snap instead of the mounts being ripped out of the wing or body.
