My question involves the swivel base assembly on my GIA GEMOLITE MARK V. I have a wiring/switch problem and need to take the rotating plate off to get access. There is an Allan socket screw on top of the base that I removed. Under that was a special washer/spacer with three through holes. It lifted off easily as did the two single-wave washers underneath. Next I see a flat piece of steel with three roll pins sticking up. The spacer with the three holes fit over these pins.
And now I'm stuck. The base still rotates as before, but has no inclination to pull free. Has anyone here had this apart before? Help.

Thought I'd update this. I never got the base apart. I was chasing the the wires as the overhead auxiliary fluorescent lamp had stopped working. I ended up pulling all of the old light out and replaced it with a 12V 15W 94X50mm COB LED Panel Light Natural White DC12V off eBay.

($8.00 eBay) and came with a remote dimmer (that worked 4 times and then gave up the ghost). I have a more standard dimmer coming ($7.00 eBay)

. This thing is bright and needs to be dimmed. I also needed a 12V transformer ($10.00 Amazon) to make it go.
It all works great and I can actually see what I'm wanting to view.

Given it is a Mk V, the base may have been untouched for over 30 years. I have taken several of these apart in the past and it is not uncommon for them to be a little difficult to remove after all the retaining parts have been removed. Soaking in WD 40 has always worked. As a last resort, carefully prying the base off, by using 2 screwdrivers positioned on opposing sides of the base (e.g. at 3 and 9 o'clock positions) so that pressure is apply evenly. When doing this, the base has always come off without having to apply any great force which could break the housing.
