    Again, the cursed lawn tractor took up my free time. Went to clean the carburetor and it nearly fell apart in my hand. I think I found the problem.

    Anyway, had to do some after market mods to the T junctions for the crossbeams.

    Man, PVC gets everywhere when you're cutting holes in it.

    Tada!

    Gonna be harambe-gluing them together this weekend.

    Also finally got around to making a custom T-shirt.

    This upcoming Thursday is when my residency with the local Makers Guild officially begins, meaning a sweet $500 to invest into it and more progress! Now I just need to get my van on the road to move the big bits...

    Settling into my workspace, but not much to show for it... doing all the boring bits first, like building a structure to support the suit while I build it. Still keeping the dream alive though. Made a nifty gif for the presentation on it I'm giving Monday.

    Settled into the maker space and built the boring bit: the Stasis dock to hold the Exo-Mech for display/suiting up.

    And put the feets in. Arms will probably hang over the sides or something.

    The entire thing collapses flat via loose-pin hinges on the back segment so it can fit in my van. Should've taken a pic but didn't :p

    Sorry for the lack of updates. Had to re-build the stasis dock as the PVC was just too jiggly at 3' segments. Its also wider: 52".

    Also built the arm superstructure.

    Pretty soon I'll have to load the top half into the van and haul it up there. And speaking of the van...

    Very discussion. Much wow XD

    Anywho, been working on some fiddly bits like the arm bowden anchors.

    And the foot straps

    And some foot extension curves (PVC pits that act like springs)

    Edit: I just realized how cool it would be to make extra-large Spartan armor or something for this...

    Did a quick test of the top half dripping with 80s cheese.



    Unfortunately the PVC frame for the arms are too heavy for the current shoulder mechanism and shift the center of gravity drastically (even if the pelvis straps were attached). I'm stripping it down to the bare minimum of just bolting the armor to a single pipe for the arms. Aesthetically there won't be any difference.

    Tested the bowden cables yesterday, and they work surprisingly well when you can figure out where to mount them. The other set should arrive tomorrow (monday) so I should have the arms finished by the end of the week.

    Meanwhile, I got some 57 lb springs to swap out the ones on bike suspension rated at 1500 lbs. The springs are too narrow to fit over the suspension cylinder, so I have to cut em down and thread 'em on keyring style... after I get the dremel attachment for cutting discs. Should work, I've had to cut a broken bearing out of my scooter before.

    Finished the ankle stabilizers (the modified bike suspension), which were hard to figure out but fun to do.

    Top to bottom: Completed stabilizer, spring partially wound on (keyring style and had to be persuaded with a hammer), cut spring, uncut spring and empty suspension cylinder.

    Completed stabilizer

    All four stabilizers:

    Whoa, that thing looks HUGE! How are you gonna walk around in it? I feel like it will be very difficult to walk around in.

    Nevertheless, it looks Papeesheewoosh! Nice work!

    So I've done a few more tests: hooked up bowden cables, added heels onto the feet and took the feet on their first test run.



    At some point during construction a stabilizer bolt on the right hand leg got bent outta shape and a stabilizer mount is on backwards, but even so it is pretty stable. That is and easy fix for this upcoming week (my work schedule changed so I can devote a few hours every day to it now).
    Pretty soon the top and bottom half shall meet!

    So... yeah. The stasis dock is too small and narrow to lift the torso high enough to attach the bottom half. I'll have to build an extension with an engine-lift style attachment.

    I also goofed up on the shin armor. All well. Makes great shoulder armor.

    And my residency at the local makerspace is coming to a close. Gonna be on display there for a month. Gives me a chance to prepare the extension and negotiate borrowing my parent's cargo trailer to bring it home. Although I seem to be in a similar predicament to that of the man who built a boat in his basement...

    Put it all together.

    Probably will invest in an electric winch for the larger stasis dock.
