My Model build to start 2021

Kenbo said:
Another 7 hours on the build today. I got the front steering linkage all made and glued to the hubs of the front tires. I also had to cut the 12 dowels that would pin and strengthen the joint between the hub and the steering linkage. Once that was dry, I sanded and shaped the linkage and then reset the dowel bearings back in place, put the tire back on the hub and then glued and pinned the inner hub retainers in place. Once they were sanded and the bearings were tested (again) to make sure that the wheels turned on them, I dry fit the front wheels in place and then dry fit the rear tires in place. That's about it for the wheels for now. Other than gluing a cap on the upright axle of the front tires and making some spacers for the front linkage, there wasn't much more to do on that so I moved on to making some of the gears and racks that I will need for the next step. I still have more to make but I just ran out of time to make them. More next week I guess. For those who are wondering, I am at 71 hours on this build so far.

That's interesting. I didn't know that but your original comment make a lot more sense to me now. Soooooo, in order to be authentic, I guess next week I will have to run this thing through the band saw and cut it right down the middle. :lol2:

Another 8-1/2 hours on the build today. I didn't get as much done as I would have hoped but what I did get done, I'm happy with. The problem was that the gears, sprockets and racks took longer to finish that anticipated and it took over 4 hours to finish them. But they are all done now with the exception of a little shaping, but that doesn't get done until I fit them in place. I also worked on the working U-joint for the steering shaft as well as connected the front steering linkage and rack in the front end. They are only dry fit and will be glued in later when I do the final tuning of the steering. I also managed to get two steering wheels glued together. I will have to finish them tomorrow after the glue is completely dry. 2 steering wheels?!?!? Yup.....hang in there. You'll see.

Stripped down the build today so that I could work on the shaft for the steering. Got both steering wheels trimmed and sanded. Spent a ridiculous amount of time getting the gears to mesh properly for the steering and mounted all the brackets so that the U-joint could sit in place. Some fine tuning of the front steering rack and once the spacers were glued in, the steering was functional. The rack and the gears at the rear of the build are just dry fit for now as I have to remove them to get the drive shaft installed. I then spent another ridiculous amount of time cutting the pieces for my next step. This is about to get nuts folks.......more tomorrow. (It's a long weekend here.)

I've probably said this before but your precision and attention to detail makes my head hurt. Awesome build Ken!

Spent 9 hours in the shop today making parts for the drive chain. It was a time consuming process of building a little drilling jig, drilling all the centres out of the dowel spacers and then using the jig to drill all (almost) 200 parts. From there it was another little jig for marking out the cutting and then cutting all of the parts over at the scroll saw. I still have to sand all the pieces but at least they are made. I guess I know what I am doing next weekend on the build.

So you're making a wooden link chain (now I see what the sprockets that you made earlier will be for). Is that for the dump bed? This won't be motorized will it?

There will be a few chains. Two will control the dump bed and one will run off the drive shaft to control the pistons of the engine.

"The pistons of the engine" did I ever tell you about Rube Goldberg machines? Imho they are now synonymous with a kenbo build...
