The progression of my XR10 into a Berg.

Well, I started off the comp today strong, and then motor gremlins showed up and went from tolerable to undrivable on the third to fourth course. Rebuilding the front did nothing to help it so its time to retire the old 5 slot broods and steal the newer motors out of the XR.

The part out of the eggshell has begun!

You did good today man! There's nothing you can do about the electronics... Just like farmer. Sucks, but you did all you could and drove well... All you can do is get ready for the next one!

Truck looked good today btw, nice work!"thumbsup"
 
I had some .75" SLW's that I wasn't too thrilled with so I decided to make some Super-SLW's. It makes sense from a design stand point to make them like this. I wonder if VP is going to offer some wheels like this?!

Weights for a bare 1" SLW wheel without lock rings or hardware is 34 grams, with 12 3/8" holes it's 29 grams and with the centers cut out and 3/16" spacers they come in at 25 grams.
 
Thanks!

For what it's worth, I think .75" width SLW's are capable of being made this way. After pulling some caliper numbers, I think the 1.0" width wheels have the centers lightened between the mounting lugs. The .75's have a continuous lug that allows for easy machining and the flat face needed to make this happen.
 
You beat me to it.
If my control PC wasn't on the fritz, I would be doing the same thing with a set of 1" wheels I have.
Except my plan was to mill some Delrin or Acetal sections to keep the halves seperated.
Thinking I need to get some more aluminum hardware and give it a try.
Know anyone that has an older computer? Need one with a LPT port and will run Windows XP.
 
There's still room to lose more weight in those wheels! You can mill slots or drill holes around the bead channel as well as removing some material from around where the hub mounts...I believe you could get a complete wheel down to around 22g.

Without a doubt there is a significant amount of additional weight to be removed from these wheels. I am more focused on the width aspect of the wheels than the weight at this moment. The weight savings is just a perk!

I made some changes to the CF wheels I have which resulted in a similar wheel, but I wasn't able to clamp the delrin in the lathe without it slipping so I dropped the idea for a while. I'm going to see if I can't figure out how to make some CF/alum wheels that have similar functionality to what's seen here.

Maybe I'll see how light I can take the S-SLW's.
 
As soon as I can find some poor soul with a computer that wants to run XP, the mill will be going again and we need some code.
I nuked ANOTHER power supply in the pc. I am just about done. Thinking its time to just get a new machine with win7 and get a motion controller.
Problem is I don't have the $$ for that right now.
 
During our local indoor comp spot restack, I was running the course set up and on my third lap during a wheels half turned blip/dig I lost all power to the front. I checked my dig button a couple times and called it quits since the motor was spinning.

Stock small third bit the dust today after half a dozen comps and just as many practice sessions.

Thanks for the offer! I have some SDS 2nd's and 3rd's that I've been holding onto for a while now in case something came up so I'm going to swap them into these axles. Not sure if I should do the 2.0mm pin mod at the same time or not since that is most likely the next weak link? But, I would rather snap a pin than strip a gear....
 
That seems to be the consensus.... I'll throw it back together with the new gears and hope for the best!
 
Check your 4th gear very carefully. In my experiences a 3rd can damage the 4th which in turns becomes a 3rd stripping machine. Make since?

Very true, that use to be the norm for me. By the way do you have some time to do some work on some wheels???:mrgreen:
Later,
Farmer
