Learning to Weld - Building a Low-Floor Wagon

This project started life as a way to learn to weld, using 25 x 25 mm square steel tube salvaged from a pallet on which a ride-on mower was delivered.  After a few practice welds, I realised there was enough square tube to fabricate a low-floor wagon which would be useful for various duties.

The welder - gasless, flux core variety.

The first step was to fabricate one sideframe, and test the strength of the welds by supporting each end on a brick and standing on the middle.  It passed.


After the success with the first sideframe, I ordered a basic welding table which would greatly assist in aligning the overall frame straight and level.

Within a relatively short time-frame, a rolling wagon emerged from the workshop.  The low level floor is a piece of chipboard which rests on conveniently located lugs which were already attached to the side pieces.  

Short lengths of 25 x 50 mm rectangular tube, left behind by the previous owner of the house, provided attachment points for the bogie pivots and couplers.


I purchased flat bar from the local hardware store to fill in the end parts of the frame.



Welded areas received a good clean-up and a coat of anti-rust primer, followed by an all-over application of Colorbond Manor Red - the railway's standard wagon colour.


The low-floor wagon is routinely used to transport the lawnmower (normal size, not ride-on) and other garden tools to far flung parts of the garden, and also the carry the wheelie bin to the front gate. 

Brake Modifications to the New Open Wagons

Both of the new open wagons include electrically-operated parking brakes on one bogie.  Parking brakes are essential as most of the track is...
