Some pre-primed pictures of my Scale_Link 60 pounder.
There are, I believe, three things that you need to do to turn the kit into a tractor wheeled version set up for traction engine and not horse towing.
Firstly of course,traction engine wheels and reversing the brake system from the kit's external shoes to shoes acting upon the inner surface of the new wheels.
Next replace the horse fittings with new tractors ones. The only picture I could find was in a US Army manual this is the closest I could get.
Thirdly the towing bracket needed "beefing ''up and a friend in the US sent me some shots and measurements of one outside his local VFW.

As Paul suggested I used SE Finecast wheels. The real ones are 60 " high. SEF wheels although of the same scale actually scale out at 72" but they are the only ones I know of and are easily available. I filed down the lozenge shape at the hub and replaced it with card. If I were doing this again I would replace the axel (part 28 ) completely with plastic rod and metal tubing as its length needs to be increased by at least an inch either side to accommodate the new wheels. I didn't and had to put a dummy wheel nut,hub and drag rope fitting on the outside edge. Again if I was to repeat this I would use card rims instead of the kit supplied w/metal ones.
The new traction engine pole for the limber and tow fitting at the end of the trail were straight forward plasticard builds.





I have built a fair few w/metal kits back in the day when resin was a novelty and some of the techniques I remembered, some I found out the hard way.
This is a heavy but still quite delicate kit.I managed to twist, bend and snap off a fair number of parts,most I replaced with Evergreen. The parts are well cast with a small amount of flash and casting ridges needing to be filed down. As usual with w/metal, all thin, rod like parts need to be replaced with brass/plastic rod if you want them to look straight.
My main, if minor, problem was with the instructions. Some parts mentioned in the build instructions were not shown on the drawing and vice versa, however I muddled through.
Paul I sent you a PM regarding the wheels and as always I am happy to share the walk around photos, sketches and measurements Jaques sent me from Illinois.
For now, into the paint queue whilst I get one with the Holt 75 that will tow it.
