Using Legacy Sonar for Live Sonar

[Rojo]

Worked on the 2D Transducer pole today to get it complete enough for a water test. I will make a video of the results with my GoPro so a condensed version can be posted.



I install a Nylon Thumb Tensioning Screw in all the Transducer Poles I fabricate. It works fantastic but they are just a touch short so I grind a flat spot on the Pivot after drilling a 3/8in hole for the Thumb Screw to go thru. TIG welding the nuts are a bit of a pain due to the Mass differences between the 2 pieces. Once the aluminum nut is welded on I pass a Tap thru the threads using Aluminum Tap Magic so the Thumb Screw turns easily.



I burned up a couple of these Motion Detectors before figuring out the TIG light was too bright for them. Now I place a ball cap over it while welding.



I just use the welding machine ground to hold the Pivot while I weld the Base Stanchion to the Pivot and the Base to the Stanchion. Transfer Punches are the Bomb to perfectly laying out the hole pattern of the RAM Ball Base on the Pivot Mtg Base. I pre-drill everything I can before welding.



After welding is complete I sand the inside of the Pivot with long straight scratches. The scratches help the Aluminum hold the grease I use. This time I didn't add a grease fitting since I have never needed to grease any of the others once assembled.



After cutting the Transducer wire exit hole and de-burring it I mounted the Transducer to the adapter, ran the Transducer wire up the pole and out the hole. First I armored just the Transducer Wire with 3/8in Convoluted Tubing then doubled it with 1/2in Convoluted Tubing at the exit hole.



I will fabricate the handle after the water test. I can use the Exit Hole for aiming for now. I need to come up with a folding handle.
