    Hi @noorbeast do you recall the wall thickness of your aluminum square tubing for the parts that deal with the wheel and pedals?
    Was at a shop with some and 1/8 inch wall 1" square tubing and putting over 200lbs of sheer force at various angles it wasn't bending with a 4ft length. 1/16 wall had did have some give. That being said, I wasn't replicating what a high torque direct drive wheel might be doing on top such a thin shaft, so curious what your wall thickness was.

    Gauge/metric measurements are fine of course :)

    Contemplating 2" up to the wheel support and then going to 1" to the pedals.

    The main aluminum tubing is 40mmx40mmx3mm, the reinforcing plates are 6mm and the bottom pedal strut is 40mmx25mmx3mm.

    First, thanks for the last reply, I'm not sure how saying "thanks" as a reply work with regards to forum rules so I usually just rate your replies (and others) thumbs up/informative mark/etc...maybe I should ask for clarification on this in the "Forum and Website" section, as I'm always thankful!

    Anyway
    Here's the link that post:
    https://www.xsimulator.net/community/threads/dx-compact-simulator.5866/#post-61899

    I'm curious how you secured the aforementioned tube, I thought you'd welded it until I read further down - so I was contemplating a longer tube that protruded beyond the walls slightly to hold itself in place to serve the same bushing purpose.

    However now am wondering, since you didn't weld it - did you just fit in a longer tube and cut it flush with the walls from the outside so that it remains "secured?" Or...??? Thanks in advance!

    The tube was cut flush with the walls from the outside so that it remains "secured", its purpose is both as a pivot and to reinforce the relatively thin square tubing from the crush force when tightened.

    Thank you!

    Looking at the image below, zoomed in - along with other images of the plate mounted to the top of the tube, I'm not sure how you made/configured the plate mount to connect with the top of the tube.

    Upon zooming (since no welding) the only thing I could think of is 3 L brackets working together around the center post: wheelMountPlate.png

    That being said...I'm not fixated on square/rectangle tubing, as I have more ideas available to make a telescoping center post, such as set screw collars and quick release bolts/fasteners that I can't find for square tubing.
    For instance down at the bottom where the center post meets the pedal tube and chair tube...could use a Ubracket[​IMG] to direct a static upright round tube...or base plates with "flange" for rectangle or round.

    The top plate is welded steel that cradles and bolts to the tube, reinforcing it as well.

    Thanks again...just thought of inverting a square tube flange so the square part is in the tube, drill through that and then the bottom of the flange is could serve as the plate itself, not sure, late night here, take care!

    Maybe...not stainless, just grabbed the first image...[​IMG]

    That should work OK, and serves a similar function.
