Wheel building , non offset hubs

[voyager]

Here is an unusual situation.
I have a pair of 28h hubs and 28 hole rims.
Went to build them up today and while lacing discovered that there is NO offset between the left and right hole drillings .
amused - not a lot.
Any ideas folks ?

My Sputniks are like that. Not an issue.

forgot to add these are 20" disc braked wheels for a trike

There often is a more obvious offset if you look inside the rim well (but it will appear to be the other way round).

I think he is talking about the hub flange drillings? I am surprised, but guess it will result in different length leading and trailing spokes?

this is the problem, l can't lace up the second side as the spokes holes are in the WRONG position, and as you say would require an (very ) odd set of spokes to build the second side .
one side can be built up with 180mm bit the second would need say 176/184 mm spokes

They are my thoughts

Ah, gotcha. Is it a 3-piece hub? On old Airlites (for example) the flanges can be quite a loose fit on the barrel and may require offsetting before building the wheel. They won't move once laced and tensioned.

this is a one piece 20mm axle hub

will post photo later

from the spoke through the holes you can see there is no offset for alternate hole lacing . The rim is a standard 28h 20" rim so harder to loose any problems

I wonder if @Yellow Saddle has a solution

Trying to think what we are missing here. I cant believe the hubs are drilled this way by accident, so there must be a method for lacing the wheel that deals with this satisfactorily?

 

[voyager]

These hubs were cut out of wheels a couple of years ago ,

These hubs were cut out of wheels a couple of years ago ,

Those wheels are probably factory wheels or the rims were matching the hub, certainly not conventional rims that you can buy off the shelf.

You will find it impossible to lace such a hub onto conventional rims.

Looks like l am going to redrill one side of each hub to suit conventional flange drilling .

Looked at the redrilling option - that is not going to happen as there is not enough meat on the flange - oh well into the scrap bin they will go -
