Beogram 4000: Installation of New Dust Cover and Aluminum Trim

The customer of a Beogram 4000 that I restored in January-February 2025 recently let me know that the new DKsoundparts hood that I installed during the restoration broke off one of the hinges. He included this sad picture:

I decided to replace the cover under warranty since it cannot be ruled out that this was caused by mounting screws that were tightened a bit too hard.

He sent me the hinge. And I installed a new hood and aluminum trim. See here if you are interested in this service. This shows the parts before installation:

First I improved the design of the plexiglass cover by installing small 3D printed plastic bits into the top ends of the 'channels' they designed into the side areas where the aluminum trim is supposed to adhere: 

These channels make it difficult to achieve a perfectly sharp bend with the trim, since it is not supported when it is bent, causing a more rounded corner.

The next step was to check whether there is any interference between the metal back and the plexiglass part when the hinges bend. The new hoods seem generally a bit tighter than the original ones and bent metal hinges can cause interference between metal and plexiglass. The resulting stress can crack the hinge areas of the plexiglass cover. I bolted the metal back onto the hood and checked if the metal would touch the plastic in any way during bending the hinge. On both sides I saw a minimum 1 mm spacing between the parts, i.e. this was a pass:

I removed the metal back again and centered the aluminum trim using my alignment pieces:

I usually use a strip of blue tape to make a pencil mark between strip and the hood:

Then it was time to bolt the metal back in. I put some white wood glue on the threads of the holes in the hinges:

This holds the bolts in place even if they are not tightened very hard.

The final step was applying the aluminum trim

and bending it down on both sides:

Nice precise corners due to my little plastic inserts! Beolovely! Here an impression of the entire dust cover assembly:

Time to send it back to Australia!
