Nice Ob1

To give help you'll need to tell me what the trouble you're having is. I'm guessing that when you put weight on them, the halves don't quite work independently, because the outer wheels are only supported on one side? (the outside, in the location of the original bearing). . .

If it's possible you might need to modify the wheels so that you can squeeze a 3rd and 4th bearing (per foot/wheel) INSIDE the inner of each of your outer BD "tyres". . (Merlyn's usual clear freespins have four bearings per wheel like this). That will prevent the wheels rubbing there and wearing down under weight. Since there will be very little spare room on the axle, these inner bearings don't need to be all the way flush with your inner edge. . . just half way in should do, then they'd help support the weight a bit, but it's hard to know if this will work from seeing the vid. . . as I'm sure you've realised by now it's quite fiddly eh? Smile

You'd have to cut away just the right amount of the inner core, and the cut would have to be true (central) and not too deep, or the bearings could slip right through allowing the tyres to come off.

Then of course, to prevent these new inner bearings from touching each other you could use speed rings, or small washers with 8mm bore. . . this ring would touch only the inner races (the bit that turns with the axle), allowing the outer halves to be truly independent. Smile

Or you could cut an old spacer down to remove the need for the central bearing.

One thing you could do to see if it's possible first, is using an emtpy axle, slide on four bearings on their own (no wheel) and a spacer. . . and see how much gap there can be between them.

Please do let us know how it goes and if you find a way to get a second set of bearings installed on the inside of the BDs. Smile

Not quite like that. . . one sec, I'll draw you a sketch. . but as I say I'm not sure how easy it will be to do this to big deuces with the tools you have available...

edit: ok, what you seem to have is this 3 bearing, no spacers design:

But if you're having a problem with this design, it could be because the middle bearing (which is touching both wheels) can't turn both ways at once, so this means the halves aren't independent. Also, the outer wheels are only supported on the outside, by the one bearing each. . . the force of your weight pressing down on them could be forcing the inside inwards, putting more pressure on the central bearing. The solution to these problems looks something like this 4 bearing + spacers design:

But as I say, I'm not sure if this would be do-able with big deuce wheels and the tools you have. There would need to still be some plastic between the inner and outer bearings of a given wheel (so the tyre doesn't come off of it's rims) and the middle spacer would need to the be the right width to keep the halves separate and yet allow the axle to fully screw into place. . . it's a balancing act, but if you get yourself some 8mm ID (inner diameter) metal pipe, and a fine junior hacksaw, you should be able to cut yourself spacers of any width you require. . failing that it might be possible to find 8mm bore washers to do the trick, but that can be fiddly. Good luck tho, let me know how it goes Smile

that looks hard and i only have one set of bd's
but what i want to know is why is the senter peace removable.

You don't need 2 pairs of BDs, just 1, but you would need more bearings is all, and yes it can be pretty hard. Unless you mean you don't want to do it in case you make your one set of BD's unusable? That I could understand. Smile

Not sure which piece you mean by the centre piece tho. You'd probably need a sketch or to edit one of my sketches to show me what you mean online. . not really possible to be clear in just text.

Ah right, I get ya. The centre piece of BD's is only removable by force. . . it's just the way they put them together. . . it's not really supposed to be "removable". . . hope that answers your question. Smile

And to put pics of stuff you draw on here you just put the following (no spaces):

[i m g] http://i657.photobucket.com/albums/uu295/obiwan1410/bds.jpg [/ i m g]

so it looks like this

If you want to see how I did that click the [quote] button and you'll see the text I typed to make the pic appear Smile

Hope that helps.

Or you could copy the [img] line photobucket supplies anyway, which looks just like that Smile

edit: seems you're getting the hang of it. . . you just need to copy the line from photobucket labelled [img] - not the one for webpages [html] Smile

Hey Obi, if you are set on making yourself some freespin type wheels (two independant halves), but you don't want to cut into your only set of BDs to fit the second set of bearings, you could try making yourself some by cutting down some Aggressive Inline Grindrock-type wheels. . . kinda like these:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370152474077

To fit two into one wheel bay they'd be a little wide (these inline wheels are 25mm and large mega bays only take wheels up to about 45mm total) so would still need cutting down width wise. . . but at least if you mess up they're less rare and easier to replace than BDs. PINKYs are ideal for medium/large mega wheel bays because they have a flat outer surface which is already about the right diameter. . . most other inline wheels have a curved outer edge, which means you need to buy them too large and mill them down.

The numbers before the "A" are how hard they are. . . for vert the higher/harder the better. BDs are 82a, Mega's 86a, Rumbles are harder than Mega's but softer than megavertz so I'd say they're about 92-ish. . . you can often find harder ones on eBay like those Pinkys 99a.

Hope this helps. Smile
