Streamlined Backshop, Wheel and Axle Wipers (aka Pickups)
« on: July 08, 2017, 11:56:45 am »
I need to add pickups to some bogie coaches and wagons, but I'm underwhelmed by the off-the-shelf options in the UK.

Now I've found an interesting selection at Streamlined Backshop (http://store.sbs4dcc.com/nscale-3.aspx). But does anyone have first hand experience of these? Particularly experience using them on Dapol/Farish bogies?

I have similar pickups , pre-fitted, on some Baltimore and Ohio passenger cars and they can cause a lot of friction making it difficult for the loco to pull them, so I would proceed with caution if you decide to use them.

Cheers John.

No actual experience of these, but must admit my first thought was the wipers would add a lot of friction.  I'd much rather use split axles and some form of bearing pickup as found on Japanese models.

Ditto the above, I've acquired a small random selection of (non-British) coaches fitted with lighting and wipers, while that doesn't seem to be much of an issue for the matching locomotives (mainly Kato and Fleischmann ones built like tanks and fitted with traction tyres) I suspect it might not work so well with British ones.

I've looked at the link, but can't see how those etches fit.
I'm not sure if life is passing me by, or trying to run me over.

They attach to the bogie pivot Malc. Two can be used per bogie in combination with Kapton insulating washers to provide 8 wheel pickup.

I've used the DCC axle pickups - springs that fit over the axle - to provide power to my flashing rear light on my container wagons.
However, they do affect the rolling resistance of my stock to the extent now that I have reduced my normal train length by a pair of container wagons.
When I find the time I need to revisit whether the 555 timer that I used to provide the flash can be operated off a 4.5 - 6 v battery.  If so then I shall get rid of the pickups.

Wow. To look at them, I wouldn't have thought they'd have such an affect - I was concerned about them making reliable electrical contact. But the main reason I rejected the DCC Concepts axle spring type, is that all my wheelsets have both wheels isolated. Though I can maybe see a way of making them work with my wheelsets, I'm not inclined to test it. I would give them a go if I could find a source of live axle wheelsets.

Thanks for all your comments. I was a little concerned about these Streamlined Backshop products adding friction and thus adversely affecting free-running - now I'm more so.

Can anyone recommend a source of 'live axle' wheelsets? I could then try the axle spring type pickups.

In reply to terryosham's post regarding 555 timer voltage supply works from 4.5V to 16V. So might be best to power it from 6volt e.g. 4 AAA batteries. Hope that helps; if you haven't already found info out already yourself  :)

If at first you don't succeed, get somebody else to do it :)

Might be worth looking at the lower voltage versions of the 555 - e.g. this, which runs on 2V, so could therefore be run on 3V from 2 1.5V batteries easily.

This would help alleviate any space problems.

Or even better, a 1.2V version, so capable of running off a single 1.5V cell.

If anyone can comment on wipers/pickups and particularly live-axle wheelsets... :thumbsup:

Just bought myself a pack of Kato 11-606 wheels (5.5mm dia with split axles and live pin-points), to experiment with axle-end pickups rather than wipers. I reckon just need to use some thin phosphor bronze pick-up strip with punched dimples for the pin-points to sit in.  If Kato and Tomix can make nice free-running pickups this way, then don't see why I can't!
