    Well, it`s not fun to work one handed. Only thing i`m almost as good lefthanded as righthanded is shooting, but that doesn`t really help me in the shop. Even holding a file to deburr some edges is really a challenge... Cleaned up the shop a bit before i started working on the axles: Had a...

    Started with a inner bushing: Then i put it in the four jaw and started tightning it. Suddenly something snapped while tightening the last jaw. First i thought i snapped the chuck key but then i realized it was my thumb. Now i`m back from the hospital, but they`re not really sure what...

    That tubing in the pivot is just for mock up purposes. It`ll be replaced with two bolts when i`m building the driveshaft. Finished mounting the pitch ram: Noticed some interference: And fixed it: Made the exhaust: And started with the shifter:

    There`s no up and down on that pivot. Front and rear car are not articulated in the horizontal plane. Instead of this, the axles will be able to articulate up and down. Hydraulic drive is no option, it loses in almost everything compared to a mechanical drivetrain. I don`t see where i`m messing...

    Because of this setup i couldn`t spin it fast. I only have carbide boring bars and they don`t like cutting speeds this low. So i found an old boring bar i braced on a piece of HSS and now i ground it and it worked flawless: Boring it out: Finished: The puzzle`s finished: Then i put...

    Started building the ram mounts today: Looks good: First set finished: Needed to bore those parts out. Couldn`t use my mill with the boring head because it`s to big and wouldn`t fit on the table with the big angle plate. So i had to mount the four jaw chuck on the lathe and bore...
