A pair of rear wheels for my 1/20th scale traction engine.
This all started with me machining the mild steel rim blanks from 4 inch diameter round 1 inch thick disc.
The machining required in this first stage was quite significant as I was removing a lot of material.
The treads took some time to machine and to get right. The 7 degree angle was difficult to replicate on the other wheel, took me two goes to achieve.
The resultant pair of treaded rims did in the end feel like an achievement.
The hubs were rather fun to make as they gave me a challenge. How do you align index machining between the two faces of the hub? The hole is a give away to how this problem was solved.
This mental challenge with manual machining is what I enjoy most about this hobby.
Assembling the wheels was very satisfying as the wheel takes shape and strength. This all relates to the design of the spoke wheel and the number of spokes.
The spokes were fixed to the rim with 8BA bolts that were then riveted over. I made a simple rivet punch using silver steel and then hardening.
a wheel assembled with all of the spokes the spokes and hubs were soft soldered the final assembled wheel a pair of finished wheels
I now have a pair of rear wheels for the 1/20th scale Burrell.
Hi great work, I am also new at building models, I am very interested in building a model Steam Traction Engine, but having problems in obtaining Plans, Very interested in building a much simpler , T/Engine……………. can you recommend one for me, I have surfed the net finding many models , but No plans , Have contacted a few model shops , but they want you to by the Kit or do not answer my emails.
Being a ex-Toolmaker , and Draftsman, with 3 d experience, now retired , I am very interested in building one, Looking for a small T/E , around 6 inches long, plus minus , maybe the first one I will use Pulleys, Have access to a workshop, so no problems there, Member of the Mens shed, Brisbane.
Can you help . many thank MIKE

Hi Mike, there aren’t many small traction engines and hence my project. I’m making plans as I go, but they are old fashioned drawings. The only other smallish option I can think of was a compressed air traction engine that appeared in Model Engineer or Engineering in Miniature some years ago. Next up and the jump is to the MyfordBoy engine. Best regards, Nigel
