I finally got some wood, of the right size, and found a bit of time from all that working from home rubbish.

(I used to think that if I worked from home I could do all sorts of modelling. Turns out the opposite is true!)

 

Anyway, two cabinets side done in two days!

I wonder if Any G (uax6) recognises the pattern of holes?

 

;)

I do! And I like the letters underneath them too!

I spent way too many hours today making just one connector block - and it's not finished yet!

However I am very pleased with it, not only because of the dimensions, but also the proportions look good too.

As a plus It is also very strong, but I will need to Counter-Sink the two free holes and source some SS M2 x 4mm screws.

Then I can mount it the right way up and have it fully populated with the correct number of screws.

 

For this Instrument I'll need to make 14 long block (as shown above) and 2 square blocks.

I'll make them out of Nickel Silver instead of brass though. (I only had brass to hand this morning.)

 

This is just part of, (like every part of this build), a feasibility study for when I make some "good" block Instruments later.

A day of CAD, one and a half days of breaking mills and drills, learning and making scrap - I finally made, (after a further 8 hours of machining!!!), what I wanted.

 

CAD with CNC - just make anything at a press of a button - yeah, right!

 

So, the CAD - easy enough.

Then the CAM to specify toolpaths, cutting speeds and depths - a bit of a ball ache!

Then the machining - a right ba$£@rd!!!

(Ping goes another bit or the job becomes loose.)

I finally settled upon (got away with) 0.33mm/s feed, a 0.25mm cut depth, and at 24000rpm!!!

 

The result (on the fifth attempt) - I'm pleased with.

(The four previous attempts are on the right but I might be able to salvage something from amongst the scrap.)

 

Next, I need to drill out the smaller holes to 1.6mm and then Tap them. The larger holes need to be counter-sunk.

After that, I can cut out the individual blocks and tidy them up before electroplating them with Tin. (Distilled vinegar and pure Tin is already on its way)

(I'll use the scrap pieces to setup on first.)

My go at a block instrument. As you will note, my interest is much more in simulating operations (timetabling, shunting, signalling etc) rather than in model making.

My model railway track is 00 gauge, sharing space above my work bench. The track consists of a terminus/ station/ goods yard with a run around loop on the right. On the left is a fiddle yard with 3 tracks. Connecting the two is a short single track line. The engines and most of the stock is GWR, bought some time ago. The ends of the track fold up to save space.

The details of how I have done it - and more importantly the things that haven't worked are in the next post.
