@Raizer had the brilliant idea of chopping screws and sharpening them into a point and using that to mark out the holes. So simple and easy.

I chopped the heads off and wangled them in the drill for a turn on the sander

Funnily enough that works and shit lines up and can be bolted up. M3 suff is tiny and fiddly to use but it's what I had in stock. My aliexpress package hasn't arrived yet with my other fasteners 

I was thinking about a dose of clear coat on the face plate, but the shiny weld and grind marks would show up. I don't have any black paint in stock. I had a quick search and found one video about finishing steel with oil. I have a mapp torch and some used engine oil so figured I'd give it a try. From what little info I found it's similar to seasoning a cast iron pan

Dunno why but I really like hex head fasteners

Gave the top plate a wire brush, degrease and a squirt of clear and sat it on the box for visual motivation

And sat the tubes in for the same reason

I'll need to re make the mounting bracket for the plate and drill and mount the switches and power socket. Then I can wire it all up

A few essential aliexpress parcels arrived today. Most importantly my rivnuts and fasteners. 

Primed the rear plate and put some holes then rivnuts in it

Made a new bracket as the other one was too small

Wanged some holes and rivnuts in. Also ckraranced it for the copper mounting bolts

Sat the top plate on so I could mark out the holes for the screws.

I'm torn between mounting the switches for setting the time on the top plate or if I chuck them on the back. Back is easier as it's thin steel and my chinesium drill bits don't like the thick plate, being on the back will be a pain to set the time though. 

I'll reread the destructions and see what I need to do wiring wise

what about mounting the switches on one of the sides?

that way the timber is easy to work with and you can stack stuff on top of the box

hmm, I'll have to have a measure of what switches I have and see if any are long enough to reach through.

The clock is smarter than me and will remember the settings/time after its set so I only really need one switch somewhere which makes it easier

Did some soldering yesterday, I'll need to flip 4 of the holders as they are numbered and I've put them in upside down

Got sick of soldering so played with the amp stuff I got off aliexpress/ebay last year. safety second. I thought I had a dud but turns out my rca cable was broken. I chopped it and soldered a new plug on it and everything works now

Also got confused af trying to read up on sub box design and all that crap. Found a useful website and ended up with some useful instructions

1x trade me special hunk of MDF

Cut it into squares and balance everything together

yCKWz2L.jpg

barry up some internal brackets, then glue and screw it together

The port timber isnt square at all. and the face plate I must have cut at the same time as its also on the piss. I might get away with a trim of them both but will re cut them tomorrow

Chopped the crooked face plate onto the port and cut a new face plate 

Marked out the appropriate circle with a bit of cardboard with a hole in the appropriate place

I don't have a jigsaw or router so barried my way through

Found a tin of half set urethane in the shed, added a splash or three of thinners and used a brush missing 90% of its bristles and sealed the box

Made up a plate for the sub wiring. Yes there's filler etc visible but it's going to get upholstered

I ordered some super cheap foam backed stuff two weeks ago and the couriers finally delivered it.
Made a start on the first wrap, there are a few cuts that aren't perfect but this is just the first layer. When I get my hands on a sewing machine it'll look less bad

Glued the last piece down and chopped out the speaker hole. I'll borrow a sewing machine for the final covering or layer. It won't be less bright than this one

I was looking for a box to fit my nixie clock in as leaving the circuitry bare was a bit dangerous. 

So I found a box. Plan is to fit it in where the radio frequency tuner was behind the glass. 
Then add a blue tooth amp board with modern speakers.

Nice! 

 

I've picked up a old valve radio that I'm planning putting a Bluetooth amp in with some magic eye tubes

Cheers, 

Yeah it’s got a magic eye tube in that little top left window. Plugged it in and got it running but I don’t think the tube lights up properly as it didn’t change when tuning the frequency.
