Building a sliding mount for my in car radio - Part 5

Just had lots of fun running the 12v supply from the engine bay of my car to a point just under my dashboard. Modern cars really know how to squeeze every last inch of space. After an hours hard work and some cut hands I finally got the cable to the correct location. I was happy to see my rig powering up and quickly grabbed a SWR meter to test the antenna. With an output of 50 Watts I have a near 1:1 SWR across the repeater and main transmission frequencies. A quick audio check confirmed I could contact Kent from the Danbury repeater. My next test is to try out the rig whilst mobile, probably on my way to work. The rig sits nicely on its slide mount and can be easily fitted and removed. I’ll probably run a short length of coax so that when I fix the mag mount I won’t have trailing leads in the foot well. Let me know if you plan to make your own slide mount and need any advice.

Now that I have my car back after its accident, I was able to attach the fixed plate that makes up the mounting point for my slide mount. I may trim the screws so that they fit flush but they don’t get in the way at the moment. The plate fits well giving a sturdy base to slide the radio onto. When the radio is in position it is very accessible and doesn’t interfere with my driving position or getting in and out of the car. The next  job is to run the power lead from the battery through the bulkhead. The end of the lead will then be stored in the dropdown tray behind the radio. I will then do something similar with the antenna lead so that it is always available at the radio end and easy for me to connect the lead from the mag-mount at the other.

I have now soldered the two channels onto the brass base. I held the channels in place with some bent paperclips which actually did a very good job. I cleaned the brass and applied some flux before heating it. The solder ran smoothly between the parts and made good clean joints. The top part of the mount slides smoothly in the channels and should hold the radio securely to the underside of my dashboard. The next job is to clean up the brass and remove any flux and excess solder.

The main part of the bracket has now been drilled and the holes countersunk. I cut down four screws and will be using both flat and crinkle washers. The preformed channels have had one end folded over and silver soldered. The next job is to clean up the brass and position the first channel ready for soldering. I plan to hold the channel in place with some bent paper clips. Hopefully this will do the job without the parts moving about. Once the first one has been soldered in position I’ll arrange the second channel so that the top part of the bracket slides in without binding. After both have been soldered I’ll have the fun of cleaning it all up.
