Mounting the new lugs is quite simple after the first few when you’ve found your knack, but you do have to stretch the fabric out with the back of your fingers a bit more than you would expect it to stretch whilst at the same time avoiding snagging the fabric with the screw. Honestly I didn’t break this frame either! Once the screw is in place you can hold the screw head tight enough with your finger to then screw on the new lug by hand.

The maximum length screw without damaging the fabric on insertion is 20mm. At least it is with the MS150s.

I wanted as smaller head as possible that would hold and not go through the hole or be seen touching the fabric (from the front).  These when in situ still have a couple of mm space away from the fabric. Enough to put a thin sticky back felt pad over the screw head if you wanted.

Time to fix those frames. I trialed various plastics and picked up some at my local Hobby shop called plastic building card, I used size 80B which is 2mm thick, it came in A4 sheets. It has a subtle flex to it whilst still being rigid and pretty lightweight. It actually turned out that each section of frame needed different size pieces cut. So it was a nice bonus to find these plastic cards cut easily with scissors. To glue them in I used a sheet of acetate under the area so not to allow glue to drip through to the fabrics, I could do without those tears later on!! I was pretty pleased with the result and none of the fixes could be seen from the front. However I just didn’t feel glue was enough.

I chose some star lock washers which worked extremely well on this, this worked well even on the lug that had completely broken away. Not a tool you want anywhere near your fragile frames, but all the same out came ‘delicate’ Cow Hammer!! Using a socket to get a nice even pressure worked a treat. Making sure to pack inbetween the fabric and frame so not to damage the fabric (for this procedure). I wanted 14mm star lock washers but the nearest my stockist had was 7/32” (13.5mm) it meant I had to slightly bend up each tab a little, there was slight variation anyway in the diameter of the lug stumps. I still think 14mm would have been better but I was on a roll and couldn’t wait for postage!

At this point I am very pleased now they are all done, the fact that they are not black like the originals no longer bothers me as they are all the same. One down, five more to go and then I might get around to my own!

The only thing I think is missing from Beoworld is more pictures of dogs and B&O, who’s with me?

A nice and original solution for this problem.  Well done and thanks for sharing.
Lovely dogs too :-)

Hi Jason

Great job and thanks for posting it. Do you have any tips how to remove the aluminium edging to enable the speaker cloth to be renewed please?

Thanks

Tim

Hi Tim,

I have removed the aluminum strips on a few of those. You have to careful and gentle of course. There will be an open seam to start with. Find it and start prying it out. The aluminum strip is just pressed into the plastic mold. The important thing to remember in prying out the aluminum is not to bend it out too far. Only pull the strip out just barely enough to clear the frame. If you try to bend the aluminum flat you will most certainly break the bend connections.
