I have used "Plastikote" grey super primer on polyurethane resin castings, overpainted with Humbrol and Tamiya acrylics.
They have been outside for three Summers and Winters and are showing no sign of flaking. Biggest problem with plastics outdoors is expansion and contraction if exposed to extremes of temperature....joints tend to open up or compress and that can cause problems if fixed to a base board.
Long runs of platform are particularly susceptible and the high coefficient of expansion means it is almost impossible to prevent unless the cast objects are left free to move.

Regards,
John.

Ralph,
Think about using Halfords car bumper primer which is quite popular I understand for plastic items outdoors. I assume it must have an etch role.  Good luck in this trail-blazing approach!

Tim,

I have a feeling that I am the only person here -so the answer will have to be "I will let you now in a few years time". I have a sheet printed PLA that you can experiment on -but I plan to use standard grey car primer on the PLA and then use polyureathane varnish on the wood work before I spray it grey. I only worry about wind damage and (now) the amount of snow the bridge will take...

regards

Does anyone have experience of using printed buildings etc in the garden, and how well they cope without getting brittle in cold weather for instance?  Another matter is how to get paint to stick and stay stuck.

The exterior wall is now complete and I have started printing the footbridge. This will be made from 150mm long modules and be 80mm wide. The first island piers have been printed and are a scale 7'6" high making the deck of the bridge 15' above platform level. I will probably design and print a set of smoke deflectors for each of the three tracks it has to span.

Progress is typically 15mins for a bracket and 75mins for a support border lattice. Printing it may not be fast but it is better than I could do!!!

Regards

Ralph

Radio Control / Ain't life getting complicated!
« Last Post by John Candy on December 06, 2017, 10:27:11 PM »
Until recently i had been using Planet T5 and Radiolink 4TEU radio control but both have now been discontinued.
The low cost 4-channel replacements are in the main "flashy" looking Flysky, Saturn and similar units which are decorated like something from a funfair display.

The plain and functional looking Radiolink T8FB looked more appealing even though I have no use for 8 channels but at 44.99GBP from Howes of Oxford looks good value (so I bought three).

The instruction manual is quite long and waffles on about simultaneous S-Bus, PPM and PWM transmissions and calibration using USB cable to a laptop with configuration software (even the default battery voltage low signal has to be set).

I am hoping that it will work in default mode out of the box but it does say default input voltage is 11.1Volts but the battery compartment accepts 4 x AA cells (i.e. max. 4.8V, so I am not convinced it will!

Anyone else tried one of these?

John.
