Re: Resistance soldering
Great video David. Not just a masterclass on the RSU, but a masterclass on how to do a great presentation as well! I have one of the original Bernard Weller units from the early 90s - I use it all the time, but I’ve picked up a lot of new ideas here especially with alternative support for the work a...

Re: Little & Large - The Socially-Distanced Challenge
Wonderful stuff Guy - so many different skills at work! Many years ago I made some printed circuit boards (PCBs) by scanning and laser printing onto silicone release paper, then laminating with a domestic iron onto copper-clad sheet before etching with ferric chloride. It worked well for PCBs but wa...

Re: Brimsdown-The last grand project.
Thanks very much Tony, much appreciated. As usual for this thread, an elegant solution!
I didn’t realise you were using a DPDT momentary to initiate the 555 reset but all now makes sense. Having the component values for the control circuit is very helpful.
Regards,
David

Re: Brimsdown-The last grand project.
Thanks Keith, that does seem extremely good value.
I was interested in the implementation of the 555 timer circuit and reset function via relay 11.

Maybe a demo at Scaleforum, just needs a few tubes of acrylic - and a willing 4 year old.

Re: Protofour W iron units
I’ve used this system too, building about two dozen wagons more than 30 years ago using ordinary rubber band strips and MJT W irons. It does seem to work fairly reliably providing the same care is taken to ensure the units are aligned carefuly and secured squarely, as applies to any system. At the t...

Re: best insulation material in loco?

Re: 1970s street scenes in colour - full of modelling detail
An interesting topic! Colour rendering in film emulsions and it's variation is a complex subject, made more difficult by our own colour perception. Kodachrome was a fairly consistent emulsion by the 1970s but even so there was variation between batches - large users for commercial purpose (such as N...

Re: Working with cutting machines
Very encouraging results, Ralph. I took delivery of the Emblaser 2 about a year ago and was quite impressed with my initial experience, using MDF, despite the clunky Laserweb package. I have downloaded Lightburn but due to office space contraints have yet to get very far with it, however it looks to...

Doug, BCS Auto paints in Sydney can supply automotive paint in smaller quantities and can ship 35mL bottles (for small repairs) by ordinary post, larger quantities (500mL or more) by road.
