Slow progress over the last few months with other domestic distractions.
I’m using 5mm thick closed cell foam as a track underlay but was concerned about the edges being vulnerable where it meets the baseboard edge. I failed to find any 5mm thick strip wood at any of the local DIY sheds but then found in my timber stash that I had 20 metres of 5 x 20mm tulip wood and walnut strip that had been abandoned here by kitchen fitters a few years ago. This was perfect for the job and strips were cut and glued around the baseboard edges and then the space within was covered with sheets of closed cell foam glued down with a latex adhesive.
I made a couple of fiddle yard cassettes using ply and aluminium angle. A kit of parts.
This is the connecting/adaptor piece with chiselled rebates for the aluminium plug and socket joining. The design is based on a
@Ian@StEnochs design on the S7 website (Members Only area - sorry!)
The completed adaptor piece. A couple of holes drilled in error visible! The ‘plug’ is at the top, the ‘socket’ at the bottom.
The matching cassette with identical attachments.
The cassette and adaptor joined together. Both ends of the cassette have the same attachment configuration.
The other end engaged.
Although they worked well, found that they I they were tedious to make with a lot of cutting, chiselling, filing, drilling, riveting and screwing. The power transfer to the cassette would be OK though via the snug plug/socket design.
