Fyi best mix ive seen for home made gears is fiberreinforced plastic. You can get liquid acrylic and shaved fiber and mix them together.

Ahh, cool suggestion. I'll try that

Hey Matt, I was wondering if you still have any wheel treads for sale for Omni-Jr? I see the old ebay link expired.

Thanks.

Hey, sorry, I had to take it down as was taking up too much of my time. I'm getting married in a couple of weeks, so will look at putting it back up when I have some more time free

Congratualtions Matt

Hello Matt,

I hope that all is going well for you and your new wife. I am still having trouble locating a set of wheels for my Robie Jr. unit. I was wondering if you have picked up making replacements again? If so, I would greatly appreciate the opportunity to get ahold of a set.

thanks!

Hi Matt,

what did you use for your grey treads?

I have the silicone molds done (left the idea of silicone for the treads since my first molds were destroyed by the silicone for the treads - silicone on silicone got just stuck together).

I had the chance to get the exact same material you used for your treads - just waiting for it to arrive here and I will start out making black treads for Omni 2k and Omni Jr.! Cant wait!

Any luck with the reproduction of the gears?

Hey @won4all. I'm currently making some tires for other folk as we speak and I have a spare set of Robbie Jr tires if you are still looking?

@mike looks like you are making some good progress. I found the same when I tried silicone, but this polyurethen rubber works perfect. The only thing I'm still struggling with is finding the perfect blue. I really want one like Josh's tires, but everything I try either comes out too translucent or almost black.

I've not really got anywhere with gear reproduction yet, things have slowed down quite a bit (My wife has started working with me so all the robots have been relegated from the office
