What happened at your workbench today?

That looks really useful..
What is the travel, please?

PhilP PhilP so I might have to fit a power buffer, but was hoping to use a cast-off 55021, but I can't find the resources for connecting to one of these.

Would this help?

Bit of a nightmare with a Brekina VW Drasine..
The 'mazac' chassis is beginning to break-down, and has blown itself apart where the motor is clamped in place..
View attachment 321311
You can also see it is delamination, along the side of the motor..

I managed to drill-through the lower mounting point, and tap 2mm. - Had to go to a M2x10mm cap-head screw.

The upper mount, the thread had pretty much gone, but there is something hard in the 'mazac' and I could not break through with the 1.6mm drill. :(
Tapped the (blind) hole, and managed to get purchase with a 6mm screw. Had to do the same on the front mounting, as well.

The pickups on the front axle are shot, and I don't have anything suitable to replace them with..

The wheels are horrible, so I might have to fit a power buffer, but was hoping to use a cast-off 55021, but I can't find the resources for connecting to one of these.

Would it be possible to cast a mould, and then re-cast a chassis/mount section?

The mould might be the easiest bit, 'cos I wouldn't know how to cast the actual bit, and what material to cast it in :worried::worried:

Or is there any chemical way of stabilising the mazac ?
 
All and sundry, especially those when you get five minutes jobs, completed, and winging their way through the postal service.

Tidy up, clear workbench for the present, bags of bubble wrap, bags of polystyrene snow, jiffy bags, cardboard boxes etc, recycled, well part traded with my local supplies shop for some essential items.

Still just about warm enough to run a train, then it's back to the Foam Core Board, and to keep the two 3D printers busy churning out items.

The Playmobil Crane project, temporarily housed in the other shed, awaiting a few items to complete the motorisation, the completed units are due for delivery in person on the 21st of next month, just seen on the left in the picture above the 'Home Brew' speed controller for testing.

Just a taster in the pictures below, this is how the motorisation looks at present, still a lot more to do, to complete the Crane Project.

To have a work bench so clean and everything organised is a sign of somebody who has way to much time on their hands.:(:(:(
;););)
 
Re post 2,745 above. disassembled and looked at various options.

Starting with the Souncards which require require 4.5V, both also require a positive trigger to activate, push button, momentary switch, Reed Switch etc could be utilised.
Connection and operation via a DCC Decoder, several options available very much depends on what type of decoder would be selected.
Volume is not great, baffle or enclosure for the speaker would improve the sound, and for the princely sum of £2.51 for a LM386 Digital Sound Amplifier Module with a 20 Times Gain would be useful.

Soundcards.jpg

The Forklift and Trailer would keep the avid tinkerer amused for several weeks enhancing re building or modifying for use.
Very simple adaptation as below, could be very easily improved.

Modified Forklift Truck and Trailer.jpg

The Forklift Mechanism itself, again could be re utilised, very simple ratchet and pulley system, again adaptable for other uses.

As for the Truck, no firm decision as yet, although thoughts are veering towards an adaption for the Hiab.
The wheels and axles from the Truck and Car, could well be utilised in the construction of one of these ideas below.

As ever, imagination, ingenuity, and creativity, keep the tinkerer amused for weeks, and for a Tenner each!, and as the 'new speak goes' thinking outside the box!:cool:

I think the truck would make a very good rail mounted engineers vehicle.
 
'ALEXA' done her thing and the heater has warmed the shed up, the great splosh of WD40 over the hinges and locks has made getting into it easier!

Returning to the trailer, a few thoughts on improving it, although the original deck plate may well suffice.

Planking perhaps, from The Works the wooden craft sticks.

Scribing Foam Core Board to simulate planking, Art Studio Embossing Tools from The Range.

Plastic Card scribed to represent planking, the two tools show below should be available form any good model shop.

Tamiya Craft Tools Plastic Scriber II.jpg

Plastruct  Plastic Scriber Cutter.jpg

Other ideas, the two red lenses salvaged from the Forklift Roll Cage, could be attached either to the frame or an additional backing to include a number plate, drawbar, coil of wire to represent an Air Hose, possibilities of hours of endless tinkering. :)
 
So it rattles in the wind. Doesn't keep the weather out, and jams solid when you try to open / close it?
:wondering:;)

:D

To answer the Rhinochugger Rhinochugger question, picture as below.

Micro Linear Servo.jpg

3D printer churning out prints for the the Linear Conversions using the SG90 Servos, although if had access to a money tree could buy these as in the picture below, with a bit of small change from £130.00!

As for anything new on the workbench, probably not now until the New Year, far to many other distractions to occupy the time during the day.

Indoor project for as and when, a pal of mine drew up a Station Building and very kindly made it available, with a judicious bit of pruning and poetic licence could be made to fit in a space available on the railway.

First pass at producing the windows as below, fairly good representation, working on the door design.

Not exactly new to the workbench, a rework of an earlier project.

For this, The MacGyver Method for Creative Problem Solving was used, for those not familiar with the method it involves three simple steps.

After working through the steps, it was determined that, the angle of the dangle was equal to twice the sag in the bag.

By the process of simple multiplication of the theory, of how long is a piece of string, a working solution was derived at.
