Excessive use of the Marquee! That's a 15 yard penalty

So over the weekend we managed to transplant all of the electronics from Gemini (V1) over to Gemini (V2). As of right now Gemini is fully operational and has been outfitted with style lighting! The only items left to complete for Gemini are the wedges and armor.

Scorpius is another story entirely. We need to complete the fabrication of the weapon assembly, which should only consist of drilling a few holes and pressing the bearing. We also need to wire everything up, program the Tx, make the armor, lighting, and keep it underweight!! The weight of this one is going to be a little closer than I like to push it, and will probably need some weight reduction performed.

This is all coming down to the last minute, but hopefully should only require a few more hours of work! We are also planning on arriving first thing Saturday morning so we can get through safety.

Oh it feels much more solid than it's last appearance. It has progressed more since the pic shown above, I will try and update the photo in the OP tonight.

It most certainly is (or at least should be!)

Latest build photos added to the OP. Scorpius & Gemini are now fully operational!!

Scorpius sounds like it is going to take off! Based on my calculations, the blade should be spinning somewhere around 6,000 RPM.

Both bots just need a few finishing touches now!

Gemini looks like a padded room to me with all the soft, eggshell curves and the plastic window... Maybe that's the "Team Brain Damage" talking...

What are you using for a bearing surface in Scorpius? Is it a live or dead shaft?

We wanted a more solid construction so we tried avoiding any unnecessary sharp corners.

 

What motor are you using in Scorpius?

With a reduction of 3:1 to the blade.

-Zac

The main design criteria was to use a dead shaft. Having watched plenty of undercutters, we wanted to avoid the typical pull that happens with a live shaft. This is our first undercutter design so I am sure we will have a fair share of flaws that need to be worked out with future revisions. The most apparent being the overall weight (its a little on the heavy side) As for the bearing surface, here is the link to the old forum that includes a section view. http://forums.delphiforums.com/n/main.asp?webtag=cjrc&nav=messages&msg=3550.1&prettyurl=%2Fcjrc%2Fmessages%2F%3Fmsg%3D3550%2E1&gid=1890736933

The bearing is a needle roller, captured by bronze thrust bearings on either side. (the blade in the image, was just for weight purposes)

So I am looking into making our own polyurethane wheels. Anyone have any experience with this? Good or bad?

I don't really have any experience with this but if I were you, I'd mold/cast the rubber directly onto the wheel's body, similar to the Colsons, and make them a larger diameter so you can lathe them prefectly concentric to the bore of the wheel. Oh, and try and get a sample of the rubber to see if it's durable enough first.

That's exactly what I am looking to do (making the molds and doing the casting). Just need to find a resource that I can learn how to do it!
