So I got side tracked again. I have been making a bunch of new Beogram frames for people around the world lately. Some people were getting frustrated that they had to reuse their original metal fixtures. So I decided to manufacture some new ones.
The idea behind it was that I know there are people out there that don’t want to buy a new frame as they would have to destroy their original frame to reuse the metal fixtures. And other people wanted to be able to swap their frames out with different timbers. As such, I remade the metal fixtures with a few slight differences from the originals.
First of all, they are in one piece instead of two. This was a necessity if I were to be able to have ‘swappable’ frames.
Second, the metal fixtures have little flanges on the outside which match with corresponding notches on the timber frame. This allows for alignment, as well as to stop the weight of the dust hood pressing down on the timber to dislodge the frame.Lastly, I removed the little tabs at the ends of the metal fixture. This was a bit of a cost/benefit analysis and the extra complexity didn’t justify the cost. Most people’s original fixtures don’t even use these tabs to hold the ends of the frame close to the chassis.
It is worth noting that the swappable frames sit in place on the flanges and are held close to the metal fixture with small magnets. As such, this isn’t permanent and the frame will move if you pull it forward, lift it up etc. However, in day to day use, you generally don’t touch the timber frame so it isn’t an issue. I have been using my swappable frame for a month now with no issues.
It is also possible to glue the frame to the metal fixture. An added benefit over the original frames are the little flanges which will counteract the force of the dust hood pressing on the timber frame when closed.
Anyway, I made a little website for those who are interested.

Here are some photos.
Close-up detail of the door and the carcass. If you look carefully, you can see the spline joint in the mitre.
On the left side of the cabinet I added wire dividers for the records and the magazines/books. I drilled several holes so that I can add/remove/reposition the dividers where needed. I have a USB C cable in here as well so I can charge my devices out of sight.
On the right side of the cabinet I have my liquor and glasses.
I didn’t end up taking any good photos of the cabinet fully finished, but here is a photo of it in the background whilst we were photographing a bunch of Beogram 400X frames I’ve been making.
Now that it’s at home I can finally spin some records again and try out a MMC20CL stylus I bought a while back!
In the below photo you can see a door after milling on the CNC. There’s a lot that goes into just making a door!
Next up was milling up the timber for the carcass.
I route a little finger joint along the length of the timber boards. There are two reasons for this. Firstly, it helps with alignment when gluing the boards together, and secondly, it essentially doubles the glue surface area creating a stronger joint.
Once the panels are glued up, they are sanded flat through the wide-belt sander. Then lots of programming on the CNC before milling. There is a distinct lack of progress photos from here on out. However, here are a couple.
This photo shows one of the side doors and how it meets the carcass. It also shows a carcass panel with a mitre and spline joint.
The centre panel is joined on the top and bottom to the carcass with a sliding dovetail joint. This allows me to glue together the outside panels of the carcass and then slide the centre panel in after the fact. It’s also a cool joint 😉
Details for the adjustable shelf pins.
Test assembling. I opted for ‘push to open’ doors for a clean look, as well as wanting to avoid catching our cloths on a door knob due when walking past the cabinet (our apartment is small). There is a small 2mm shadow line between the door and the carcass edge detail.
The base is made with 6mm thick aluminium angle along the length of the base, with slender round aluminium legs. The legs have been notched to accept the angle, and then will be bolted on. The base will be powder coated matte black to match the Beogram chassis.
Thanks, guys!
It has been a while since my last update. I got a little sidetracked. I have had my working Beogram 4002 packed away as we got a puppy late last year and needed to pack away the speakers as well they were just calling out to be chewed. Molly (the best and most beautiful dog in the world 😉 haha) is now beyond her chewing phase and I pray to the dog gods that she won’t find interest in the Kvadrat cover of my Beosound A9.
This got me thinking… I have a beautiful record player that is tucked away around a corner, but should in fact have a place front and centre in our little apartment. As such, I decided to take a break from restoring the trashed 4002 and make a record player cabinet. Some of the requirements were:
– oak timber to match the dog
– big enough to house my small but growing record collection
– room for magazines
– room for my liquor collection and glasses
– hidden cable management
– USB cable accessible internally to have my iPad/MacBook out of sight and charging
– the base needs to be tall enough to allow the robot vacuum/mop to clean underneath
– similar aesthetic to the Beogram
– adjustable shelves
So I went about drawing up a minimalist cabinet and then set out to make it.
The carcass is made from solid oak. The front edge will be 6mm to reference the Beogram frame. The idea is that it would look minimalist and delicate. To achieve this I would have to bevel the inside of the carcass and subsequently the doors as well. As such, the doors would have chamfered edges to fit. Solid timber doors are not very stable as wood moves considerably with humidity. I started the build by resawing solid oak into ~3mm veneers on the bandsaw. These got ‘stitched’ together into a veneer leaf. The substrate of the doors is chipboard to provide dimensional stability. However, as the edges of the doors need to be chamfered, this required ~20mm thick edging. I laminated the borders on then laminated the veneer to the substrate.
Some images: Cutting the thick veneers on the band saw.

The veneers get ‘stitched’ into a leaf.
Here you can see the wide edges laminated to the chipboard substrate and the veneer leafs off to the side.
The veneer is then laminated onto the substrate using a vacuum press.
So I managed to do a good print today! The photos are a bit blurry but in real life it turned out quite crisp.
Just a quick update. The restoration has been on hold for a while as I waited for a screen printing screen to arrive. I am going to try to screen print the writing on the chassis and aluminium strip on the lid. I’ve never done it before but I thought I’d give it a crack. From my understanding, the Beograms that have been officially restored have the writing on the underside of the chassis replaced by stickers. To me, for such an expensive upgrade, it looks kind of cheap. So I am going the ‘overkill’ route and trying to screen print it.
As a reminder, this is what it looked like when I got it.
This is what the chassis looks like after sandblasting and painting.
I made up an image with all the various text that I am planning on restoring at some point and popped it all on the one screen. Ideally, I will make a screen which has all the writing laid out properly so I don’t have to realign and print the various text in stages but can do it all in one go. But this is essentially a bit of a trial run.
I didn’t have a squeegee so I whipped one up.
The first try worked really well. But when I tried printing the second ‘play – transport’ text it smudged so I will have to start again. I will give it a try again tomorrow.
I will post some photos as soon as I manage to pull off a good print. And then I can start the reassembling process.
Here are some photos of the 4000c style plinths I have been making for people. Each plinth is made from one length of timber so that the grain matches and flows around the whole plinth. From what I have seen of the plinths on the 4000c from B&O, I would say that my quality is as good, if not better than theirs. There is a lot of attention to detail on these. All joints are tight, edges crisp etc.
Here are some photos of the 4000c style plinths. The joint itself is slightly different, as well as the addition of splines. The joints are so tiny.
I have received a great reception to offering the new plinths for sale. Over the past few weeks I have been busy making and shipping them off to people in the US, Denmark, UK, France and Germany. As such my restoration has been taken a back seat for a little bit. Here are a few photos.
I had the chassis and back parts sand blasted to remove all the old paint. The surface finish was quite rough on the inside so I had it wet blasted to bring back some shine. I then primed and painted it black. I used a spray can which was quite difficult to get a good finish but I got there in the end. On my next restoration I will use a proper spray gun as it will be way easier and get a better result.
This is a detail diagram of the classic joint.
And this is the 4000c joinery. Note, this joint has an extra rebate as well as splines.
After a few people have shown interest in the timber plinths, I’ve decided to make them available to others to buy.
I spent some time researching and working out a way to send such a fragile piece, and I think I have found a good solution. I will custom make the boxes which should be able to withstand international shipping. The aim was to make a box that doesn’t compress or twist and which weighs less than 1kg in total to make shipping more affordable.
The plinths will be made to order, in solid timber, and come with 3M industrial strength double sided adhesive tape, instructions on how to fix the plinth to the metal fixtures, and a spare sachet of hardwax oil finish for future maintenance.
I currently have access to oak, walnut, ash, maple and cherry, but depending on demand, I could possibly source mahogany, teak and potentially rosewood (Brazilian rosewood seems almost impossible to get, but Indian rosewood might be an acceptable alternative).
I will offer two different joints; the classic joinery as per the original plinths, or the Beogram 4000c joinery which is slightly different and has splines.
Currently I will use Osmo hardwax oil to finish the timber, but am open to UV stable lacquer, soaped finish, and other finishes if requested.
