"Thin/Top" Eccentric Cam

"Thick/Bottom" Eccentric Cam

Make a sharpie mark on the side of the Rotor where it lines up with the B and T label on each Rotors

Tube end with the two drilled holes = Cam End

Tube end with the one drilled hole = Pulley End

Insert 6701 Bearings to both Top and Bottom Rotors as well as the Top Housing

Slide the Bottom Eccentric Cam to the 2nd hole from the edge in the Cam End of the Brass Tube

First hole is on the other side of the Tube

Align the set screw holes and screw its place using the M3x4mm Set Screw

Slide the Bottom Rotor to the Bottom Eccentric Cam

Label Side of the Rotor is facing the Cam End

Repeat the process with the Top Eccentric Cam and Rotor

Label Side of the Rotor is facing the Cam End

Align the Side Sharpie mark on the Bottom Rotor to the "B" label on the Housing and slide only the Bottom Rotor into the Housing

Align the Side Sharpie mark on the Top Rotor to the "T" labelled on the Housing and slide the rest of the Rotor in.

If everything went smoothly, the gap between 8 holes on each rotor should be equally spaced

Insert 6701 Bearing on the Top Housing

Secure the Top Housing to the Rotor Housing using the M3x20mm Screws

Align the Pulley Gear to the Set Screw and slide in the Pulley gear to the Brass Tube

Secure it using M3x4mm Set Screw

[3D] - 5Aa Fork {Bottom & Top}

MF83 Flanged Bearings [3x8x4mm] (x8)

M3x20mm Screws (x4)

M3 Hex Nuts (x4)

M3 Nylock Nuts (x4)

Insert MF83 Bearings into the Bearing Sleeves

Insert the M3x20mm Screw in to the Fork Half where there's a chamfered peg on the inner face

Slide one of the Bearing Sleeves to the M3x20mm Screwss with the flanged part on the bottom

Use M3 Hex Nut to secure the Bearing Sleeve in place

Insert another one of the Bearing Sleeves on the M3x20mm Screws but this time with the flanged part facing up

Use M3 Nylock Nuts to secure it in place

Repeat the procedure for 3 other locations.

M3x22mm Screws (x6)

M3x4.5x12mm Hex Standoffs (x7)

M3 Square Nuts (x2)

Place the GT2x400mm Timing Belt on the outer pulley on Assembled Ulna Gearbox

Place the GT2x336mm Timing Belt on the inner pulley

Align the Ulna Sensor Plate and Ulna Output Gearbox to the Fork Bottom with the Hex Standoff insert pointing upward

Insert M3x4.5x12mm Hex standoffs and secure its place using M3x22mm Screws

Use M3x10mm Screw in this location

Insert the Picasso Output pins to the Picasso Gearbox

Rotate the Input Pulley of the Picasso Gearbox to align the gearbox housing

Insert the assembled Picasso Box into the Bearing Slots of the Fork Bottom

Insert M3 Square Nuts in the Square Nut insert on the Fork Bottom

Secure the Picasso Gearbox by tightening the bottom screws on the Gearbox Housing

Fork Bottom Prepared

Fork Top {w/ Idlers Installed}

M3x10mm Screw (x1)

M3x25mm Screws (x6)

M3 Nylock Nuts (x4)

M3 Square Nuts (x2)

[Opt.] - Tape

Insert the M3 Square Nuts in the Fork Top

Insert the M3 Nylock Nuts in both Fork Top and Bottom on the side wall

Optionally, put tape over the nuts as the friction fit alone may not be enough to keep them on.

Align the 400mm GT2-Timing Belt {outer belt} to the Top Idler

Take the Belt off of the Gearbox Pulley if you need to.

Rotate the Top Fork and let it FLOAT over the Bottom Fork

Put the 400mm Belt back on the Pulley

Notice that the Top Fork is shifted forward relative to the Bottom Fork

While the Fork is shifted forward, put the 336mm GT2-Timing Belt on the Inner Pulley on the other side

Shift the Top Fork back and align the "Pulley Separating Wall"

Once all Hex Standoffs are aligned too, Clamp the Top Fork down

Secure the Picasso Gearbox to the Top Fork by tightening the top screws on the Housing

Use M3x25mm Screws and M3x10mm screw to secure the Top Fork to the Bottom Fork
