Very Nice - looks good!! What did you use as your offset?
i was shooting for 3/16" from the centerline (it's a WM4 rim), but ended up around .23". Plan is to mount both rims and check alignment prior to final tightening of the spokes.Very Nice - looks good!! What did you use as your offset?
Nice.
Put a carpenters laser right where the camera is (maybe a bit higher) and running dead center up the spine. Align the rear rim to the laser, and then you have a reference for where the adjusters should be set from to remain even.
And if you put a level across the frame on the shock gussets beforehand, you get to see if your rim is plumb.
I was initially told that too, but then the tire runs slightly off centre to the rear fender/ rest of the bike. They should be offset 3/16" to the right. Laying a straight edge across a WM3 steel rim, there should be about a 1/16" gap between the straight edge and the hub on the sprocket side flange.Is that hub one of Don's?
I asked him about offset and he told me there wasn't any.
No, about 20 years ago by the old scottish guy who taught me how to build wheels. Referring to standard Norton Commando rear wheels.Initially told? Did Don tell you different after he told you there was no offset?
Don's supplied right hand spacer is different (shorter) than stock.
IMHO there is no point in building the rear wheel until forks and front wheel are fitted. Front wheel is the datum.But at this point there are no forks...
But there is a point to building the rear wheel first if that’s the first wheel you buildIMHO there is no point in building the rear wheel until forks and front wheel are fitted. Front wheel is the datum.
Absolutely agree.But there is a point to building the rear wheel first if that’s the first wheel you build
Interesting. What's his frame of reference when he said no offset? The rim or the centerline? And assume that's off a stock WM2 rimAnswer from Don,
Yes, (No Offset) but like any wheel set up I advise wheel alignment check, especially with Commando with isolastics.
I would assume you would want the wheel centered in the swing arm? If so, then the method I detailed above (measuring the stack width of everything that fits between the ears of the swing arm then divide by two to find the centre) takes all the debate and guess work out of it.But as Don mentions, "Like any wheel set up I advise wheel alignment check, especially with Commando with isolastics".
IMHO, centered in the swingarm is unimportant (the swingarm is not symmetrical). Two things are important to me:I would assume you would want the wheel centered in the swing arm? If so, then the method I detailed above (measuring the stack width of everything that fits between the ears of the swing arm then divide by two to find the centre) takes all the debate and guess work out of it.
If you do want it slightly off set, then, offset it by adding the value to the center point measurement described above.
This is easiest to do with a bare hub.
FWIW
