Default Advancements regarding this "sequel' of the project

Hand-sanded the iron parts and finally, have it painted professionally. This time, they left some wax in the box, so the paint isn't that flush at the linings as at the other speaker's transformer boxie.

Default screws...

I wanted to throw out these, but realised that this is different thread size than Metric, so cleaned them thoroughly. Hot water and vinegar can do wonders. This time, these bolts were coated with something to keep them from corrosion. The other speaker's wasn't.
I will now use a little oil to avoid corrosion.

Default Bass panel's dustcover frames

This was the most annoying and tiring part yet. I do not have the right place to do it with the least hassle, so I done it with my raw physical strength and with some sandpapers.

I tried out my mahagony mordant on it to lessen the wood's natural bright yellow color. I think, I will use it on all the 6 frames later.

Default treble panel

I cleaned the panel with white cement (removed the insulating tape this time as it was sooo old) and 70% alcohol, removed the wiring completely, and soldered some reused but good quality wires from an another treble panel.
The dust cover is just on it temporary, as I will use my mahagony on it.

Default little work on the frame

I know, it is useless, but done some cosmetical work on the frames (lovely to do a work on something that is not even on display, ha-ha, but anyway)
First, I cut a bit off from these protruding supporting pins as they were too long that the treble panel rather sat on those pins than the wood support itself. I used my sandpaper again to remove the zig-zags from these hardwood supports.

Before I would use a good drip free spray paint and then into the oven at low heat for a few hours. Now my metal work and welding projects get a spray paint and hang out in the hot Thailand sun a few hours and it's a better finish than the oven. Glad that you are taking your time to do it right.

Yes, I would gladly did the same, but the paint job by a powder coating company was relatively cheap and hassle free so I opted for that. I really do not have the right accessories for this quality of work on iron based materials however the wooden frame was painted by me at the other speaker, and I am pleased with the result.
