What happened at your workbench today?

The first coat of paint. The roof will be black or some shad of it. Yea I know, black is black, I want my baby back.....See how I went right into song.....:giggle:

I have been doing roofs with a spray of matt grey immediately followed by a dust over with matt black, I was quite pleased with the result. But I was doing this in Somerset when weather outside was warm as were the spray cans.
 
Firstly a thank you to (Martyn) aka viaEstrecha viaEstrecha for donating the following as in the below picture.

Incidentally, if anyone else should be having a clearout/tidyup/ of surplus no longer required decoders, please do get in touch.

Rest assured they will be put to good use, one of the ideas for 2024 is provide information on DCC Decoders, to Members of the G Scale Society and via the Local Area Groups.

Various test rigs have been setup to provide a simple a solution with a hands on approach, to the identification of a decoder, its CV's and the values of said CV's.

In conjunction with the above, is the rewrite of the existing decoder manuals to include the most up to date information available.

Sample front cover of the new document for the LGB Small Onboard Decoder, there is no documentation specifically for this decoder, the information available as such is lumped together into an existing document.

As a visual teaching aid, new decoder templates have been created, to allow experimentation of READing and WRITing CV's.
Whilst they are not always necessary to program a decoder, they do provide a visual indication of what is happening.

Some parts of the documentation, decoder templates, have been written for the following decoders, 55021, 55022, 55027, 55028, 55029, LGB Onboard, Small, Large and Sound.

Many more hours of proofreading and double checking the contents of both the documentation and decoder templates, a thank you also to the Management of Massoth who permitted the necessary changes to the Massoth Service Tool Software to allow the creation of non Massoth decoder templates.

Whilst I am not a fan of Marklin per se, they have made some changes to the mDT3 software which has a least made life a little easier with the CV's on the 55029 decoder, although the program itself is still lacking in its ability to be a useful Tool for DCC, which is not overly surprising as Marklin is actively promoting mfx!
 
A bit more progress on the castle.

Quite literally as this is updated, the remaining parts are being printed, probably another six hours to go, as the sections are assembled they are tested.

Testing with DC and literally crawls along, good even coverage on the up and down scale of the speed controller, onwards and slowly edging to the finish line.

All parts now printed, motor units greased and on test to run them in, probably not much more will be done with them until next week.

Looking good..
Did you print your own gears, or are they a commercial offering?

PhilP
 
External Gears are 3D printed, smaller one with a D Shaft for push fit onto the N20 Motor, large gear tapped to take two grub screws, flat sections filed into the 3mm LGB axles for extra purchase for the grub screws.

Same methodology used as per the printing of the Gears for the Servo Linear Racks as pictured and described some way further back up this thread.
 
Wheel wipers for power, innards from a Choc Block, fitted into a 3D housing, Phosphor Brown strip.

Other half assembled and tested, two complete units working, need to clear some space on the workbench, then marry up to the original Playmobil Crane, pure guesswork from now on connecting it all together!

Located all the bits, trial test fit and onwards..................

OK, nerd mode on, and in no way disparaging for your amazing efforts, but what are the chances (or not) of the motors on one leg running a smidgen quicker than those on the other leg?

Must be honest, I'm only thinking aloud, and would it be any different to having power on one leg only ?

I s'pose with four motors, the chances are reduced, as any disparity in performance would mean that the motors fight the one on the same leg before fighting the other leg - or are the motors sufficiently small for it not to matter and I can go back to sleep?

:nerd::nerd::nerd:
 
From the testing regime, all four motors with their associated and modified gearboxes, run at the same RPM, there is a small margin of error, as the maths appears to be correct.

The tolerances of the 3D printed gears will compensate for any minor irregularities, as with all these things it's being constructed from a hobbyist viewpoint, and not totally from an Engineer's viewpoint, although an Engineer was responsible for the final gear ratios, so if it all goes Pete Tong, I'll blame him! :)

Bit of a mess waiting to put live steamers back on shelves, live steam black box and other stuff away plus sort out of non important TT120 work for now away.image.jpg
 
Not a loco or rolling stock, but workshop storage, my latest EMBA paint drawer:

I am slowly moving from enamels to acrylics, so will need fresh storage. I bought a 14 ml tinlet drawer some time ago and a "bits" rack both from EMBA, and being impressed, that they are modular both up and across keeps things neat:

Easy to assemble, just PVA glue, and the slot and tab construction makes them quite solid.
