Dear Friends, I'm lacing a set of flanged alloys (WM2x19" and WM3x18")to a standard rear hub and to a front tls drum( 1968 t120.) I followed a guide published on a 1998 Vintage Bike in lacing the rear wheel (worked wonderfully) but I am stumped at the apparent discrepancy between the article and the shop manual concerning the offset: the manual lists 1.75" from hub to rim while the article lists 0.5". The manual also lists -1/64 for the front, while measuring the offset for what seems an original front drum-Dunlop WM-2 gives ~1/8 (+) Please Advise. Thank You, Michael
When I laced up my wheels, I too was baffled by the offset figures in the manual. What I did was to roughly build the front wheel, then mount it on the bike and center it between the forks and true it exactly. Then I built the rear wheel, mounted it on the bike, and brought it into line with the front wheel. This can be done by lightly strapping two long fluorescent bulbs (or other straightedges such as angle iron) to the rear wheel with bungee cords so that they pass on either side of the front wheel. This takes work, of course, but I think the boys at Meriden were eager to get off to the pub when they wrote the section on wheel offsets. I have had no problems with this setup in many thousands of miles, and the sprockets seem to line up exactly. If anyone knows better, let us know!
I am lacing my first wheel. I have the 19" WM2 Front. The wheel is CWC and the spoke kit is from Buchanan. On the drum side they are 4 3/4 spokes. 10 are on the inside and 10 on the outside.The other 20 straight ones go on the other side as I am sure you know. My question is: Does the wheel have to be flipped a certain way or can you start on either side? On the drum side I put the correct spokes on the outside(The 90 degree hook) and inside(A little more radical hook) as directed by Buchanan but the drum edge is recessed quite a bit from the wheel.It looks way off center. All the spokes fit in naturally with a struggle so I am sure I have the right nipple holes plus I had a few pictures from The Triumph Jockey Journal. Do I need o flip the wheel over and start lacing from the other side? Any help would be appreciated.
