I will leave them unpainted - ABS is very durable.

That is interesting! I am going to follow your lead. Not with a point motor but a manual crank lever. As an aside how do the electronics you are using cope outside!philipy wrote: ↑Tue Sep 06, 2022 10:24 amI printed cranks and bases in PLA ( using brass screws as pivots) and they have been fine outside for 3 years so far.Trevor Thompson wrote: ↑Mon Sep 05, 2022 8:42 pm
I am also thinking about cranks, rodding, and a ground frame to operate those points. Perhaps cranks and guides for the rodding could be printed? Dare I even print the ground frame?

In this picture the operating servo is hidden under a printed hollow pile of sleepers, also in PLA.
If it's any use, I've just put the stl's in the print files section.Trevor Thompson wrote: ↑Tue Sep 06, 2022 9:51 pm

Thanks for the reminder Peter - I should have remembered that. I like the idea of burying it in the ballast.Peter Butler wrote: ↑Sat Dec 10, 2022 1:18 pm Trevor, perhaps a bicycle cable (Bowden cable) could be fitted to operate the point further from your lever? I have successfully used them, one about 3m. long, which works perfectly. The outer cable can be covered in ballast with a short wire visible at the end if required.
A wagon with deep flanges is a good idea. I will have to try that.Old Man Aaron wrote: ↑Thu Dec 15, 2022 11:49 am Coming on well as always.
Love the "Victorian-Era" ballast. I keep a pair of deep-flanged "pizza cutter" toy train wheelsets to swap out on one of my plastic open wagons. I push the wagon to and fro, to clear the flangeway area, after applying dry ballast mixes over the top of sleepers, prior to gluing it all down. If the pizza-cutters run without crunching over ballast, the proper 16mm wheels will, too.
As for anchoring down your crank bases, I think mechanical reinforcement is needed. You could drill holes through the bases, (or include in the prints) and use the stainless wire to "pin" the bases down, driving perhaps 2" lengths into the ballast with a hammer and/or pliers. Just a thought.
Yep - there were loads of large roots in the way - had to use the chain saw to remove them!
