How do you know which way to feed the thing onto the cutter?

From one or two builds I've seen, Judith Edge stuff is top drawer.

I shall be interested in this build for if they ever release 97650 in 7mm.

Lovely.

It's models like yours that give others inspiration.

I reckon this would make a good thread/discussion on the main board. I'd like to see what you've done, certainly.

Hi biffo.

I too wonder about the missing bass in model loco sounds.

Years ago I used to work from a book called "More about Loudspeakers" by G A Briggs, who was the design engineer for Wharfedale speakers BEFORE they were sold to Rank. And became Rank!

There were quite a few tricks to "fool" a little speaker into making more bass, including;

1. Reflex enclosures, where the speaker sits at the front, but the air BEHIND it is in a zig-zag path. The longer the path, the bigger the enclosure "appears" to be.

2. Filling LOOSELY, or partially, loosely , the enclosure with a sort of wooly foam. The sides were lagged with it and any hard surface.

3. Venting the enclosure: it needs a vent so it can move air, the more the better. Completely sealing it will just stop any air moving and add to the tinny sounds..

Can I suggest Googling loudspeaker design?

It's very errrrrrrrrrrr, steep?

Sounds quite good.

Have you ever been to the Gainsborough Model Railway Society's layout?

An "O" gauge version of the above, VERY interesting.

Superb. I keep forgetting to look at this since it became a blog, but it continues to excel.
