I haven’t done any composite design for a long time, but from what I remember… The typical use would be: skin - film adhesive - core (rohacell or aluminium honeycomb) - film adhesive - skin Vacuum bag to consolidate and into the autoclave for curing. The main thing is that the core must do two thing...

Rohacell sheets might be worth a try. Possibly easier (less messy) than expanding foam, and more consistent. But one of its attractions is low mass, which may not be important in a speaker?

Just been to see Jack Johnson at a lovely new venue, on the mount at Wasing. A small natural amphitheatre surrounded by forest. Jack was on top form.

Ethernet connectivity between my laptop and the CNC router is now flaky and dropping out frequently. Lead is fine when I checked it. Had a quick look for industrial rj45 connectors, but am drawing a blank for anything sub £100. As thought I would change the socket on the CNC to something you can sc...

Lubricating oils are designed to work over a certain temperature range, depending on the application.
So with motor oil I would be worried that the viscosity might be too high at room temp.
Slideway oil and fishing reel oil do sound like better candidates

See if you can find an adapter that allows you to fit current production batteries from Ryobi or someone to your Hitachi tool. I am planning to do the same to allow me to use my dewalt tools again, after the aftermarket batteries from Amazon died after a few cycles

I picked up the cable tester from Screwfix (identical model to Nick’s but different branding) Tested end to end (from the powerline all the way to the cabinet in the loft) and #4 was open. Then tested the in-wall cable on its own, and it checked out OK - big relief. Then tested all other cables and ...

I remember the days when graphic equalisers (along with FFT type displays) were common, often built into the system.
Some of them had a bypass or direct switch, and I can’t remember hearing a big difference.
I suppose there are filters - are they passive? Would they introduce phase lag?

Actually, looking at your photos, I reckon you've got that loop pretty small

I've ordered that cable tester. I can't help thinking it's quite a coincidence that a few hours after I hooked up a powerline adapter for the new inverter in the garage, the powerline network stopped working.....and the fault turns out to be a network cable in the house that has been happy for proba...

You can run 100Mbs on two pairs if you can find two pairs that are still ok. Need a cable tester Brian Good idea, thanks Brian I used one of these to check the cable when I wired in the new office here (and just moved the other end last week in advance of getting rid of the old office/shed) https:/...

They were never supposed to work very well on different ring mains, though I never seemed to have much of a problem. Maybe they're better now, or maybe the 17m distance is an issue? That signal actually has to go from the lounge socket to the house consumer unit, through the cable from the house CU...

Aaargh Apologies, false alarm. The ISP router at the front of the house is connected to the middle of the house by a pair of ethernet cables. (I was only able to retro fit in-wall cabling to a couple of places in the house). One of those cables has decided to stop working. It happened to be the cabl...
