Walker Diesel Class F - ECMbuild in 4mm for OOn3

Recommended Posts

Hi all

Well still waiting for the bogie parts, but in the mean time I got the second bonnet up and running and also started on some of the small detail bits

Exhaust pipe components- aluminium tube with soldered brass mounting brackets

A bit of moulding done to create the bonnet headlamp bodies- the trusty Model T van was used, a nice set of lamps on the front, did not want to wreck the part so I did a mould around the lights still on the radiator grill! it worked

two lamp bodies drilled to take little LEDs

Ladders, other exhaust n brackets, the horns, and the side bonnet radiator water filler caps- all brass

I'm thinking of making up my own motor chassis for this project, but unfortunately I cannot show a sketch, today my workshop PC decided to melt one of its drives and the walker directory was in that sector, fortunately I could back up most of the drive and thankfully I had done a system backup last month, unfortunately the edit to the drawing with the chassis design was only last week and it did not get saved in that backup, and again- fortunately Windows has a secret directory that backups get saved, even incremental! I got almost all the data back from here and it needs a few hours drawing and I'm back to last weeks version...... Backups guys, is very important

anyway, brass etched bogie with Mashima motor on top n pulley drive all hung off a PCB chassis plate, I've setup a drawing of the bogie frames to make a mould, this includes connection rods & crank counter weights to be etched in brass- i'll make contact again on supply of these parts and then make a decision.....

So you thought I'd forgotten the Walker!

No word back from the supplier on bogie parts since March?? so I decided to fabricate my own- based on the rubber band drive idea I'm working on for the N 141.....

The drawing was completed for the bogie frames, bogie bolsters, motor system, fuel tanks, bogie sides, cranks, and crank counter weights- all to be cnc cut from .3mm NS sheet;-

A close up of the parts, all the cutting worked out fine with a 1mm end mill and the half cut done with an 45deg engraving tool for the fold lines;-762512870_WD-39IMAG4120.jpg.3698b7e1e6cdd8fc36993acce4318c72.jpg

The chassis plate was cut out of .7mm PCB board with engraved lines to position the fuel tanks and bogie bolsters when soldering on, one of those D shapes will be pressed out for the motor pulley drive to go through to drive the bogie ;-

All the parts removed from the sheet and on the right is the motor bogie frame cleaned up and about to be folded, soldered and wheeled- though need to make a few long axles as we have outside cranks. There are 110 parts to make up the wheeled motor bogie with side-frame details, I have only cut out parts for one set of side-frames, if all goes together OK! I will be making moulds from these for casting white metal sides;-

So a bit of processing over the week end........

Hi Eoin

There is a good reason why you haven't heard back from Malcolm Savage, he is no long with us he died about three or four months ago I think.

The good news is that some one is thinking about taking over his range, so hopefully it won't be too long before his bits become available again.

 

Regards

Colin

I must get on with my own Class F loco model at some point.

Hi Colin R

That's sad to hear,

I thought something was wrong all right, I got no reply from my follow-up emails... so left him alone.
