I allowed myself to remain distracted.....still needs a little more cutting and I'm pretty sure I'll need to relocate the controller.

Bought this little guy to see what all goes on between the steering unit and the hack box. there are probably even cheaper options but this looked easy to use which makes it my speed I hope. The fiesta EPS is kind of chunky and annoyingly shaped but have myself convinced I'll get a better outcome than the much cleaner prius setup.....this should help me figure out if that is true.

That's 1 side...hopefully the quickener shows up today so I can have a look at side 2

The quickener arrived about 3:30 and has been kicking my butt since.....but I think I finally have something workable shaping up. The shafts are rock hard and the gear part needs to stay that way so I dropped the gear end in water and heated the rest Attachment: 20210313_155953-resized-1024.jpg [ 158.76 KiB | Viewed 5689 times ] Then the one housing got shortened 1/2" and the shaft about 1.25" and will be adapted to the OEM u-joint that locks on with a taper pin...they are 3" over-all and the shortest I found and I have it. The other housing piece will get shortened more and the seal and 1 of the 2 bearings removed as there is a bearing in the EPS unit then welded to the EPS housing cover. The shaft will get cut and bores to slip over the EPS shaft which also gets cut and I'll pin them together. Then the steering column gets shortened about 2" so the u joint sits up against the bearing retaining nut....and there should be just enough room for the steering wheel height adjustment to still work....at least in theory.

After a full day of making stuff shorter it all fits. Left to do: 1) The top u-joint uses a taper pin so I need to get a reamer for that 2) Connect the quickener housing to the EPS housing 3) Some kind of cover for the big hole I cut lest I be BLASTED with hot radiator air 4) Wire up and test the EPS

Like I said, cut and weld will make it happen. Bam, there ya go. |

Its close now, still not really working but with a few more days effort I think it will work. It should end up 1.6 turns but I'm not quite far enough along to be able to check it, this was just the first test fit where it at least fit into the space. Up at the column (yellow arrow) the u joint is still a slip fit and sitting about 1/8" higher than I'd like and down where the quickener shaft meets the EPS shaft (green arrow) its also still a slip fit and that is where I need to cut another 1/8 out before I weld it I guess. Then not clearly visible is the quickener is hitting the bulkhead on top and I really can't get to the EPS connectors....probably 2-3 more full days before it works then another couple days on the how to close the big hole I cut problem.

Its so close to steering again. I shortened the quickener another 3/8", machined the housing to accept a clamp to secure it to the EPS (but still need to make said clamp), welded the shafts together, drilled a hole for the pin at the steering column, cut a notch to clearance the quickener, cut away a chuck of the EPS housing to expose the wires which should let me mount the controller in the cabin with no additional work.

It steers again. A few little mechanical things left and then on to getting the EPS powered up....and the hole sealed up. https://youtu.be/j6BqsdwOwRI |
