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.
Get some half inch hex bar and turn it down for bearings
I need all the wheels driven.
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?
I now have 21 of these wheels to sell... I screwed up on the Banebots order too.
Lol!!!!!!!!!
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.
What Diameter are the drill shafts and what thread do they use?
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
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.
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.
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.
got any 40 shore?
Nope, 50 only. Sorry. After the state of Binky's wheels I think we are going to stick with 50 shore from now on.
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.
I have successfully found a way of resizing the holes with no difficulty at all.
If anyone want want wheels with the 1/2 inch Hex hole then let me know ASAP as I will be converting them all unless I hear otherwise.
There are 13 still unmodified so take your pick.
I now have 13 wheels left to modify and I will be doing them all tomorrow. If anyone wants any unmodified ones say now; that is with a 1/2 inch hex hole.
