Hayfields 7mm 3D Printed Turnouts

[martin_wynne]

Needs the FDM supports removed, bonding wires and tie bar fitting

And painting, and ballasting, and some cosmetic fishplates, and ...

To create some wood texture "grain" effect -- splits, cracks, sawmill marks, etc., streak a little white typing correction fluid* on the timbers before painting.

*from the pound shop. Still used in schools, for crafts, etc. Dries quickly in thick streaks.

Martin.

A test build of a V6 single slip which has been on the back burner for a while, finished today and learnt some lessons for a better version. Tested with a 4 wheel coach but needs tiebars and wiring to test fully



You may see the Templot Tiebar (designed to be covered by some ballasted card, next one will be built using the CARROT version



End of a V6 diamond using the CARROT version, center third on the printer



Batch printed some Templot tiebars

The center section was both designed and printed



Followed by printing another crossing



And some chairs, though at worst some may have to be chopped up a bit

The first thing I did was to cut out and form all the rails (some left over length) as I formulated a build sequence



With the stock and closure rails in place I cut the obtuse bent rails to length, then fitted them in place with various chairs I printed, some cut in half to aid construction



Both obtuse crossing stock rails were fitted



Then the check rails had half chairs added and stuck into place



After electrical bonding wires were added I was able to bench test the diamond crossing



Adding etched fishplates to the rail joins

All in all so very much easier than a total scratch build. Certainly a very much quicker build.

A few track build skills are required plus a bit of track building experience. but nothing like what's required in scratch building.

I initially was a bit skeptical about the FDM printed check and wing rails prior to building both a turnout and this diamond crossing, but it simply makes life so much easier, not to say far more accurate. A big thumbs up from me

about the resin printed check and wing rails

Hi John,

Typo? FDM ?

Hi John,

Typo? FDM ?

Thanks

I have had a busy couple of weeks, an interesting and challenging (I am not used Zoom very much, let alone using 2 computers plus switching between 3 programs) evening session over the internet last week, since then I have been preparing for Guildex at Stafford show ground this weekend



Terry Downs who owns Kosmik will be there both days, Terry as well as being a 3D printing guru also laser cuts track bases and does other 3D activities. Martin Wynne will be there on Saturday and I will also be there both days.

Terry will be giving a short presentation at 10am Saturday in the lecture hall

There will be 2 computers with monitors so we can show how Templot 2D & 3D works and hopefully my printer will be working in the background

Do come and say hello, we have asked for a few extra chairs so folk can sit and see Templot in action
Terry has offered (if possible) to look at any Templot files you have (put them on a USB stick) and on Saturday we have Martins wealth of knowledge to fall back on

I see you're on stand D5 John, I'm next to you in D6 all weekend. Will be very interesting to see those printed tiebars in the flesh.

After concentrating on Guildex, then a week later going to Puglia for our holiday, my 3D printer has been a bit inactive. Firstly I wanted a break from track building, secondly I wanted to dismantle an old EM gauge project to make space for a mini 7mm scale layout in my workroom

The design is nothing more than a larger scenic test track/storage yard for stock, a very much shortened terminus

As well as starting to clear the baseboards, my wife volunteered me to clear some remnants of his past railway modeling activities, surprising how this eats away at ones time

Track roughly laid out simply to see what it will look like

The first set of prints to 0mf standard have been printed, they need a bit of tidying up and rails fitted, prior to a closed cell foam track bed being laid,

Nothing very interesting or ground breaking, but it's not only a very economical way to produce track, but built to a scale gauge not supported by the RTR trade and designed with 60' track panels with 12" sleepers at both ends using S1J chairs. Why use flexi track when you can accurately print the curves you require, you never know but it might actually catch on one day

For anyone thinking of having a go with 3D printing both the A1 and A1mini now being sold at knock down prices (A1 now £199 mini £130ish?)
