13x 73mmx20mm Banebots 50 Shore wheels with 1/2 inch Hex Mount

[Eventorizon]

As in the title. Just got these from Kenny and I made the mistake of thinking you need a 1/2 inch next hole for a 1/2 inch shaft. Wrong. you need 3/4 inch.

Brand new and unused. Lots of road miles. PM me offers.

I would prefer to sell them together as I only have 1 box.

[typhoon_driver]

Get some half inch hex bar and turn it down for bearings

[Eventorizon]

I need all the wheels driven.

[Eventorizon]

I Found a big stack of padded envelopes so I can send wheels out as needed until I run out of packages.

Still for sale! I can't have been the only person in need of wheels?

[Eventorizon]

I now have 21 of these wheels to sell... I screwed up on the Banebots order too.

[typhoon_driver]

Lol!!!!!!!!!

[PJ-27]

Haha, make a 21 wheeled robot.

Dan may need a load of wheels for his educational project but all depends on how cheaply you're willing to let them go and how adaptable they are to Drill shafts.

[Eventorizon]

What Diameter are the drill shafts and what thread do they use?

[typhoon_driver]

12mm and it's a 3/8" UNF thread. The banebots hex hubs use a half inch shaft so you have to shim a thin piece of metal in the annulus between shaft and bore to get a good fit that doesn't wobble as I had to do with boner for the champs

[Eventorizon]

They may be using a different type. If it is 12mm then it might be possible to just get away with a 1/2" bar and lathe out 12mm from the centre.
I am going to talk with my technicians. As the main wheel body is Polyprop, we may be able to use a jig in the Laser cutter to recut the hex holes in the wheels out to 3/4 inch.

[typhoon_driver]

1/2 inch = 12.7mm

Therefore you would be left with a tube with a wall thickness of 0.3mm. No lathe chuck that I know of would be able to hold that without crushing it.

Just chuck the wheels on ebay at a discount and there you go.

[Eventorizon]

I know the maths Gary. I will find a way unless anyone needs wheels with the 1/2 inch hex.

21 of these wheels for sale still. PM me offers.

[harry hills]

got any 40 shore?

[Eventorizon]

Nope, 50 only. Sorry. After the state of Binky's wheels I think we are going to stick with 50 shore from now on.

[Dan-27]

I've bought a load of blue rubber wheels from Bearing boys for the robot kits I'm building.

I had the same problem with some Bainbots wheels I bought for my uni project. I found the 3/8" UNF nuts were just a little too large so I found some 1/2" hexagonal bar and tapped a 3/8" UNF thread in it. Took a 8.5mm pilot and I turned them down to 17.5mm long (wheel hubs are 18mm) with a couple of washers pressing the wheels into the shoulder on the drill motors it works fine.
