d00m Posted September 13, 2021 Share Posted September 13, 2021 (edited) Does anyone know what size (gauge) wire pick up springs are made from? I should say it's for OO gauge (dcc concepts make them). 0.3, 0.4 or 0.5 mm etc.? Edited September 14, 2021 by d00m missed a bit Link to post Share on other sites More sharing options...
d00m Posted September 17, 2021 Author Share Posted September 17, 2021 No one replied to this, but, if you are interested, I ordered a 40m roll of 0.4mm brass wire @£5.00. It easily wraps around an axle as a pickup and works really well. (It might be slightly better using 0.3mm). Well worth doing as it saves ££££'s. 3 Link to post Share on other sites More sharing options...

I normally add a coil to mine which allows for plenty f relative movement on a compensated chassis. I normally rest them onto the flange. The images illustrate it best.

d00m Posted September 18, 2021 Author Share Posted September 18, 2021 That chassis looks amazing! Hadn't thought of using it like that on locos... it may be time for me to look at some troublesome pickups on one of my 14xx. I was looking at coach lighting and the springs DCC concepts sell - low friction axle pickups - hand winding onto an axle is remarkably easy and extremely effective, but I will try 0.3mm on the next set.

Sir TophamHatt Posted September 20, 2021 Share Posted September 20, 2021 (edited) I ordered some 2mm springs, which from the DCC Concepts page, suggests they're good for OO gauge. Ordered mine from Coastal DCC - superb service every time! Not sure what this measurement refers to though.

Hand winding 0.3mm brass wire on to axles is dead easy and saves having to take insulated wheel off to get springs on. Also, as you are making them yourself, you can leave a longer 'tail' on the spring... 1 Link to post Share on other sites More sharing options...

Perhaps at some point I'll convert them. 1 Link to post Share on other sites More sharing options...
