I have 80 tooth pulleys in stock, but they are for the torque limiter only.

OK then, what's the damage for that 80t x 25 guy?

[RWP]

Hey Matt,
Can you give me a price on the 80t x 25 pulley?
Oh, and do you have those 20" wheels yet?

Hey Roy,

Sorry, I missed your response on the thread.

Yes, the wheels are in stock. All domestic multiple rim orders have been shipped. Individual rim and oversees orders are shipping next.

The 80 tooth pulley is $58.

I got a little progress done last night, I'm not too happy with the setup, so we will see if it lasts. I decided and try an 8mm shaft system for the jackshaft. It's kinda dainty just looking at it, but I'm working with what I have here, so we will see how it goes. I recently picked up a stock Turnigy 80-85 170KV which I plan to run with my Castle HV110. I hope to have it running this weekend. Things left to do:

1. Sliding motor mount/ jackshaft plate
2. Drill sprocket adapter for disc hub mounting.
3. Prep motor pulley for shaft mounting
4. Rig up #219 chain tensioner and link 2 chains together
5. Lace up rear wheel with new SS hub and wide rim from Matt
6. Weld brake posts on

Ok, all that won't be done this weekend, but I hope to at least get a rear wheel spinning on the bench. Oh yeah, and a big thanks to SoSauty for sending me his spate parts, I will b using a few for this build.

Got a bit of work done this weekend. I will probably be slowing down a bit as Jay and I will not be able to make it out to the Grange track.

I have managed to get the width down less than 5 inches and shouldn't clip ankles on spinny parts (always a bonus). I got the mounting plate done, I just need to finish pressing out the motor shaft and cut the shaft and flatten the drive side for this pulley. Then I can get it mounted. I will probably have to space the plate off the mounts by about 1/2". I'm debating on lacing this wheel with a dish toward the pedal side and attempting a disc brake with Hope Monos. The hub is much wider spoke flange than a cassette hub, so strength shouldn't be an issue. Plus it might actually be easier than mounting brake bosses for rim brakes.

Damn Dave you be building some wicked crazy Sh### ! A lot better than what you brung to the DR race I went too.. Something wicked this way comes!

[etard]

Damn straight man! My Death Race build was some hacked together shit done in my backyard, now I have a legit workshop and nearly every tool I need. I had the DR bike geared wrong but I had that thing running pretty good for about 1/2 a lap!

Seriously, mad props to any non-hub builders out there that don't have access to machine tools like a lathe and mill, there is no way I could have gotten this far without these two machines. I'm constantly using one or the other.

[Arlo1]

Awesome might need to get you to build me some shit one day!

The anodized purple piece, is that a stock bearing carrier from a go-kart of some kind?
soz if i missed its description...coming along nicely anyhoot...OH teehehe.. And what a 'gloooorious'

Arlo,
I owe you that, let me know what you need, as long as it's not too complicated and I promise not to ship UPS.

AJ,
You guessed it man, here it is:

http://www.ebay.com/itm/Racing-Go-kart- ... _705wt_952

I think it's gonna work perfect for this application. After I finish this one, I might make another one that I can swap in or out in less than five minutes. On that one I will put three one-way bearings inside a tube and see if I can't get rid of the freewheel.

On another note, I measured this cable pull cheap disc caliper here ( Walmart special) and was happy that it only has about 13mm width on the backside of the caliper,so I will be treating the disc brake adapter to fit a 180mm disc on it. I am VERY happy to put a disc brake on the back of this bike. I also will be ordering up a BB tube and making an eccentric type mount for it to ease chain tensioning issues. I'm also thinking about turning that extra bottom bracket tube into some sort of center stand.

Arlo,

You don't owe me anything. Im sure ups will try to send me a second bill as they usually do but I put them on my ignore list lol.
As for when I picked up the power supplies they charged me $28 so not to bad compared to normal. And it was not your fault you were doing me a huge favour so Its all good I really appreciate your efforts.

Plenty of room in the triangle for batteries on this bike, but a future build might have me going this way for the Battery capacity:






As seen here:
http://www.gizmag.com/solid-gray-backpa ... re/147601/

I think you could fit a good amount of batteries and also quickly remove it for battery exchange, or even have two backpacks.

[wineboyrider]

Dude that backpack is so Ironman looking. Are you sure you don't work for Stark enterprises?

HAHA! No, I work for Dork Enterprises!

A little more progress on the reduction pulley, still have to bore it out for the support bearing that will go behind the freewheel, but I was happy when I found these allen bolts with "shoulders" on them, should work perfect for this application. They also look like they would work perfect as a chain tensioner bolt with a bearing on the axle part.




Here is the bolt:




AND I also won a proper toolpost on ebay today for way less than I expected!

[Thud]

look at all the love you put on that cast motor mount!
whats your plan for that? Glad to see you getting some use out of the old samples box.

[etard]

I was hoping you would see that! Monster sprocket all the way bro!! I already picked up another scrap frame to hack up ala Thud 4 1/2" sparkomatic.

I was thinking about how to keep the freewheel from pulling into the pulley ( kinda need to keep it spaced out so it doesn't interfere) and came uo with a solution: sandwiching a bearing between the freewheel adapter and the pulley. That should keel everything aligned and together at the same time.

Hey etard,

Any more progress on this awesome (re)build? And did you ever get the jr Brute going again

Simon.

Actually yes, I am chipping away at her when I get time. Thanks for the kind complement, I can't take any credit as Thud is really the mastermind behind the curtains pulling all the strings. The Jr. brute is in the middle of a rebuild and will be a little smaller, lighter and more beautiful than before. I should really get that thing going soon so I can go practice some laps around Grange next month.

Ok, so I had a freewheel adapted to the pulley, wasn't content and wanted to try a sprag bearing from VXB. I decided to the 25mm would fit the bill with 68 n.m. of torque handling, which should be able to handle the 80-100 after a 3:1 reduction. We will see! Here are some pics of the jackshaft. I decided to go with a 1/2" to 3/4" delrin adapter for the #219 drive sprocket just to see if it softens or lasts in the application. I wish metal was this easy to machine!

I still need to order up some spokes, then I will have a roller!










The center part is attached to the shaft with set screws while the inner sprag ring is keyed onto the shaft carrier. The outer ring of the bearing is keyed onto the sprocket mount and also the sprocket. This setup is solid and a bit heavy, I just hope it is balanced! There is the motor plate slotted and ready to go as well.

[etard]

Bump...

[etard]

She's a roller.

[nicobie]

Looking good!

[etard]

Are you coming down for the race Nico ?

Ughhh, KFF strikes again:





My index finger actually feels like a hammer hit it. I hope i can put a glove on for the race.

[adrian_sm]

Quite a collection of bikes, will be interesting to see how they all stack up against each other.

Hope you have better luck at the races than you do with handling batteries.

[Thud]

tsk,tsk.
this is just heart breaking.....time to call the ASPEC on your malitious practices..(American Society for the Protection of Ellectrical Connectors)
looks like the new chargers are working properly too!

Ice that burn down, schmere it with vasoline & get a surgical ruber gloves to wear inside your normal glove to stop any chaffing.....or really man up, rub some dirt on it & get back in the game!

& be carfull for crying out loud.

the age old question, barbecue sauce or ranch?
