First time out this year, silver, and an excal fix

[teklord]

After being out of commission since January with a torn retina and the new full time job of " Mr. Mom " I finally got out for 2 whole hours on Saturday. My wife and I went out to Cocoa with the baby to visit a friend who has a condo on the beach. It felt great to get out if only for a short spin. Found 51 cents, 2 pull tabs, and a .925 spinner ring in the wet sand. The plastic shaft on my Excal where the coil attaches slipped out of the metal shaft. I think it is only glued in. I drilled a hole and added a bolt which should fix the problem permanently. The conditions were good and I wish I had time to go deep in the water, the waves were low and the tide was going out. Next time...

That's a great ring. With all the jewelry I recover, I have yet to get a spinner ring. Keep it comin.

the bolt may be to close to the coil? there are usually plastc rivits near where your bolt is. that bolt might be interfering with/decreasing your coils sensetivity?

 

[JRich98150]

I agree with Seeker. You certainly need to make a trip to the local hardware store and get a few plastic bolts and nuts (never hurts to have an extra or two.) I would not use a metal bolt and nut so close to your coil. I would think the metal nut and bolt would certainly have some effect on the coil. Go with the nylon or plastic hardware down there.

You might replace that aluminum bolt and wingnut with the plastic kind....Your coil will pick that up, way to close. HH John

I think the bolt may be far enough away, but if I have any problems I'll switch it out with a nylon bolt like the one that attaches the coil at the bottom.

Hey teklord,
I had the same problem earlyer this year I called minelab and they gave me the number to a place that repairs them here in Michigan I talked to him and he told me to use JB weld it's what he uses so I tried it haven't had a problem since it's been 4 months. The only draw back is you have to let it cure and dry for 14 hours. I would loose the bolt though the reason I say this is not only because of the sens. issue but I would be afraid of the fiberglass cracking after awhile.

Thank you all for the input. When I move an aluminium bar past the area where the bolt is I get a solid reading which fades out about 4-5 inches above. I will definitely switch to nylon. Why does the aluminum shaft itself not cause a problem in this area?

Have to put in my nickel's worth ...

I know that metal near the coil which is stationary has only an electrical properties effect. For example if you tape a penny to the coil it will have an effect on the coil properties (the coil wires are metal too) but not picked up in the motion mode.

I wonder if metal like that might not have a positive effect too? Hmm Maybe an interesting project to try?

PS: please correct me if I am totally off base here.

 

[digum smacks]

just epoxy it back in there no more worries

 

[scrounger d detector collector]

u might think a 1200 dollar machine could be engineered

so as not to have such problems in the first place

 

[Treasure_Hunter]

I used epoxy like Snookson suggests ( ) on mine 3 years ago, hasn't had a problem since.......

DREWAN........YES!! we need the number to the repair center that you were refering to!!!!!!!!!!!!

TEKLORD.............. i used waterproof marine epoxy and its still holding!!!!

TEKLORD..................... your lower shaft should be fiberglass not aluminum.

 

[time4me]

That lower shaft should be fiberglass, not aluminum.

Mine fell apart exactly as you describe, and I just used epoxy to bond it back together. Been fine ever since.

Good luck!

The bolt will not effect the coil as it does not move. Nautilus detectors come with a stainless bolt to hold the coil on. Some of the deepest detectors out there.

I got out again yesterday for 3 hours, 76 cents and a junque ear ring.

The stainless steel bolt worked fine. 99 % of the time I am running with discrimination on. In pinpoint you get a slight reading but none at all with disc on. Against the majority of advice here I am going with the hardware over the glue. I am more concerned about the damn thing falling apart than anything else.

lots of people at the beach yesterday.
