21E tram truck

And this is the tram with the top deck resting on lower deck along with some of the seats I've designed.

The truck fits perfectly. Just waiting on gears and motors, and I had to print up a set of 30mm wheels, but otherwise the only tweak I'll make is for the bearings, as they are a little loose. I'll thicken up the walls of the hub, so I can then drill them back out to a snug fit.

Dear all,

The same question, a different answer. I prefer wood, steel, brass, bronze and other traditional materials, like real trams.

1) Here is the construction of an Istanbul tram:

The truck is made in stainless steel, the axle boxes too.
- 24V Maxon motor (8 watt)
- brass gears
- brass bearings

The tram body is from Occre is improved as follows
- correct colours and lining
- water decals for correct destination boards, company logo, etc (as per Belgium factory drawings)
- new scale bow collector, footsteps, buffers

2) A tram from the "Tramway Electrique Ostende Littoral", private line that ran between Ostend and Westende (Belgium), prior to the take-over by the vicinal (SNCV)

This one is 100% own design, with laser cut wood and metal.
The Brill 21e side frames come from KW trams

Definitely nice work there! When you look at the relative costs and barriers to entry though it becomes very clear why someone might choose 3D printed and nylon gears instead. Also at least for me a fully enclosed gearbox is a must for running outside.

Very nice! Good to see these finding some applications.
 
Dear all,

a late comment, I did not look at this forum for a couple of years.

Regarding costs, it depends how you work and what you intend to do.

I do not want to invest in a 3D printer, so if I am forced to do so, I use the services of www.craftcloud3D.com because you have the choice between 40+ printing materials and price competition between suppliers.

- Metal laser cutting is not expensive if you plan to make say 5 trams (in my case OCCRE Istanbul (done) , Barcelona (done), Buenos Aires (in progress), Soller and Lisbon (later)
Then choose the right material plate (different sizes) and fill the plate with loads of pieces to cut.
I have made 5 Brill 21e trucks.
It translates into 10 truck frames, 20 axle boxes, etc.
Quantities such that each individual piece come to a couple of €, £ or $, or less if they are small
I use Spanish or German companies (EEC ones) like Laserboost.com. (Stainless steel or brass)
Easy, you send a DXF file, get an online pricing, leaving the opportunity to choose best or cheapest
If you are member of a club, this is probably a good solution. OK, you need to agree on what you do.

- Wood laser cutting. Same story.
I use the services of the Dutch comhany www.laserbeest.nl
Useful because wide choice of material, from thin and flexible 0,6mm plywood and other wood, transparent material for windows, etc.
Then choose the right material plate (different sizes) Fill the plate with many pieces
Approximative price: 30 x40 cm plate with dozens of bits and pieces will cost you, say 30-40 €, £ or $
I guess similar services can be found in countries with borders (UK, US, etc)

- regarding gears, I have looked everywher in Europe, UK and the US.
I have found in Poland/Germany a company seeling "everything" you need: you choose the type of teeth (modulus) and amount of theeth (one by one ) and material.
Brass is slightly more expensive but does not "die" after a couple of years
