PCB Etching

I needed a few small PCBs but did not want to get too complicated with laser printers and light sources etc. My cupboards of shame have far too many unused tools in them. The board is rectangular with a gap along the centre of the long side and 4 holes. 241 Tender PCB P4 Single.PNG This is easy to m...

Re: Thin-walled brass tube

On a 5' 6" boiler using 12' (0.3mm) brass the boiler measurements are shown in the attachment with the main boiler shown in red. There is almost a 2 mm difference between the outer and inner circumferences.

Re: Who would want a form tool for re-profiling wheels?

Terry,
I have a pile of AG wheels that are EM. If I can reprofile these to P4 it would save me more than the proposed cost of the tool.

I also wonder if the 3D wheel printing enthusiasts could use this for sizes not available fro our few sources of wheels.

Heat Shrink Sleeve to cover the tags


Just a thought, but I use heat shrink sleeve over the motor tags, these help to stabilise the position of the wire as well as insulating the bare ends. Use the tip of a soldering iron, cose but not touching, wavinving it over the joint area until the sleeve has shrunk.

Re: Brass preparation for painting

I find that the use of Cif (formerly Cilit Bang I think) always reacts with the solder on a model, leaving a dark surface layer that can be rubbed off with a finger. Once I have cleaned using this I always take a fibre glass brush over these surfaces to remove this residue. I think the only solution...

Re: Drill for rivets.

If the rivets are 1.1 mm (check them first) then I would suggest a slightly smaller drill hole, 1.0 or 1.05 mm. This way, when you turn over the track base to apply the trusty sprung centre punch, they will not fall out. I would suggest that drilling 1.1 mm through what is a thin ply will always cre...
