Steering knuckles pretty much done. Comes to 30" bang-on, as desired, wheel to wheel centerline.

One month later, the Steering knuckles are near to done. Just need to drill and tap for fasteners.

"Terror Trikes" ... interesting. I'm a rank noob when it comes to Tadpole trike Geometry, but i've got experience with Sidecar rigs - a mix of Theoretical methodology and invocation of Dark Arts in setting those up, so they aren't 'Terror Trikes'... I assumed that the sketchy handling at...

It's very much velocity contingent, based on a downslope bias. As you put it, it's potentially Oscillation inducing with oversteer. Anything under 30km/h / 20mph - entirely manageable. It gets dicey above that. Routinely reaching 50km/h in those optimal gravity-hill conditions, i want...

Finally got around to finishing off one aspect of the SWB Terratrike - overall Stability/Sensitivity of the front end, which definitely gets twitchy with a dangerous tendency to oversteer and possibly have a CofG shift induced roll-over, if it gets too loose, at too high a speed on steep...

Starting to plan out for the Electronics. I insist on having my stuff encased. Can't handle the idea of electronics being exposed to elements/possible soaking, so am following my previous successful test of an enclosed electronics case, as with my Terratrike project. I found an electronics...

Getting down to the nitty gritty of fabrication - Old School hand-crafting style. Drill press, hacksaw blade, 1/8" drill bit, break out the section that has been outline-drilled, then file, file, file.. 3/4"x1 1/2" rectangular tubing for maximum strength/rigidity. Fitting into slots, 1"...

4 Dozen, even, of that type, actually.. most common used are the red shorts Alloy, which come out to about $5.00 per from the cheapest seller on Ali-express. There are 48 of those in the mix (to my count) .. the black stems are slightly cheaper, and i have 6 of those in play at the moment. The...

Closer, getting closer to final configuration - obviously, some of my plans are obsolete, some are being realized. It's an evolving design, definitely. One thing is clear - it is going to be one heck of a chain-line involved, including the likely need for sprocket jack-shafts to abruptly...

The parts continue to flow in, and the need for additional parts needing to be ordered continues... Fortunately, it's coming down to the cheaper parts and bits and pieces... I received a Terratrike 18" crank boom today that I will work with into the setup.. there will be a bit of additional...

Hasn't been much in the way of updates as of late - very much a process of putting things together in certain configurations, taking things back apart, looking at it from a different angle or dimension, and refining. It's starting to get close in terms of general configuration. 48 'red' stems...

The 'Project', such as it is, graduated from being a trip-hazard between kitchen and stairs, to being an official "Coffee Table" Imagineering Project this past week. Keep in mind, it's roughed in dimensionally - I plan to narrow up the 'spine' a bit more, and everything else needs to be played...

This is actually a hard-shell recumbent seat that i'm utilizing. I've already got one on my rigid Terra Trike - and it's mounting method was relatively involved, requiring significant metal fabrication of seat mounts to adapt to the Terra Trike method of seat mounting. Using this fabrication...

Starting to play with the Chassis Ideas... strictly exploration to see fabrication potential. Built in Roll-bar! The bottom and top compound curve pieces are the main parts of a automotive bicycle rack, that i had found curb-side last summer. Reduce, reuse, repurpose! I like the idea...

Well, plans are definitely fluid, in terms of shifting goals. I've got lots of Pie in the Sky ideas - but the more i look at things, i am fighting multiple issues - complexity, dimensional vs material limitations, and my own over-ambition. I need to look a this in terms of a modular approach...
