Nearly nearly nearly done!

Works with my old charger. This one from memory is configured for 1amp but the new ones I will configure for 2amps. Although I won't build them as "hyperchargers". Too much feature creep and the dinky size of the standard one looks better alongside it.

In the meantime I've been adding to the pile of parts for the twin build so it's sister is ready to roll too.

Sealed up the front footpad and took a pic. I think it looks suuuper good even though I haven't put the bearings on. They are purely decorative and don't really provide any structural support since the motor itself rests on the 8mm axle.

Here's a quick vid of me testing it under its own power even with the busted tire.

Ignore my broken thumbnail 😭😭😭I hate it so much. Gonna take months to grow that claw back 😡

Managed to finally get another batch of PU rubber and set off a second casting. This time I tried another technique involving 3 pours one after the other to get a cascading curing process where the last one combined the 2 halves together.

It begins to cure after just 1 minute an has a pot life of 5-6 minutes. That's enough to dye, mix and de-gas just as it starts to set. Pouring takes about another minute as it's pretty viscous stuff. So if you time it right you can cascade the curing times to get a desired fill. I did:
1x 500ml batch and pour split between the 2 halves to create the outer most faces.
1x 400ml batch and pour split again between the 2 halves to top off both moulds.
1x 100ml batch and pour on 1 mould as I flip the other and squish out the excess and clamp it closed to combine the still not fully cured material.

Sadly I didn't get pics or vids of the process as it's a very involved process with no time to mess with a phone especially when I'm using it as a timer 😅

My 2 clamps were not enough so a car battery was brought in to assist with pressure.

Regardless the tire came out fine minus a slight offset meaning some of the internal geometry isn't aligned but it still fits the motor casing just with more resistance instaling.

Also found the tires make a great display stand.

So I need to fit the new tire but I have another set of things to do so in order these are left to do.

  • Install the bearings.
  • Shorten the battery harness cable a bit.
  • Adjust the LED programming so it's more consistent.
  • Alter the footpad resistors so it is more sensitive at lower weights. Probably a 20k resistor instead of 1k by my calculations.
  • Sand down the bumpers to line up with the footpads.
  • Spray paint the bumpers.
  • Add white colouring to the Vega logo.

Since the programming port for the VESC is still accessible via the back of the controller I'll tune the board once re-assembled as it's a bit looser than Mission and I want a more Delirium feel for showing it off.

Once I have this one done though I'll see if I can poke FM on insta and see if they'll swing by OpenSauce to see it in person. You know, to give it the official seal of approval 🥰
