Hi John I think you will find that the ML was originally laced as a cross 2 spoke pattern. The fact that it has 36 hole rims gives a bit more angle on the spokes compared to a 40 hole rim. As 1951superlux states above, the acceleration and braking on the ML does not warrant cross 3 or 4 spoke patterns. You should be able to confirm the original spoke pattern from the spoke lengths quoted in the 1947 James ML Parts Book. Front & Rear Rims: 19" WMO 36 Hole. FRONT WHEEL SPOKES.Brake Side: 8 5/16" ( 211 mm) × 12 gauge. Plain Side: 8 11/16" ( 221 mm ) × 12 gauge. REAR WHEEL SPOKES.Brake Side: 7 1/2" ( 191 mm ) × 12 gauge. Plain Side: 8 9/16" (217 mm ) × 12 gauge. I have never had a go at building spoke wheels but I might have to have a go in the near future. You may find the attached information on the Les Taverner wheel building jig useful. Regards Butty Bach

Most interesting. I had 3 sets of wheels, and they were all different in the way that they were laced well at least the rears. I did find that the brake side and sprocket sides were reversed, I know that is a bit odd. I did note that the lengths that you mentioned are correct for the spokes that I have. There is more to this mystery I'm sure but thank you for your time and help with this issue. I was about to de-spoke the rear wheel I picked up in Davenport last year, it has a cross 3 pattern on the sprocket side. Now I will have a cup of coffee and stare at the wheel.
Cheers John in Texas

According to Peter Miller's book on the ML, The rear wheel is 2-cross on the brake side and 3-cross on the sprocket side

I just removed the rear tire on the spare wheel, it was so fossilized I had to cut it off. This is the one with the cross 3 on the sprocket side. I have a shallow pan with some used motor oil to soak the spoke nipples, hope that will help with disassembly of the wheel. Thanks to all John in Texas

If I wasn't bald already this bike would have me pulling my hair out. Went to fit the exhaust system back on and the header pipes wouldn't fit into the separator. Started measuring and the pipes are about 1/16" bigger that the inlet to the separator. Started looking at the pipes and I realized that the pipes were plumbing drainpipe like you might find under the bathroom sink. I looked around and it doesn't look like places like Armors has them anymore. I doubt that they were ever a big seller. Been looking at YouTube and I see that there is a way to reduce the size of the pipe. Just hope that the pipe being what it is isn't too thin walled to allow me to do that. I might go over to the local muffler shop and see what they say. John in Texas

Hi John
It's not meant to be easy or anyone could do it. How about cutting the exhaust pipes back a bit and turning up some steel adaptors that fit into the separator and either inside or outside the exhaust pipes.
If the pipes are not plated the adaptors can be brazed inside, if they are they could be slotted and clamped up on the outside. Not ideal as it will not look original but it would work.
Regards Butty Bach

I have ordered the "The Famous James Military Lightweight" through Abe Books. Should have it in a few weeks. Thanks for the tip. John in Texas

If I could add my two pennorth, I always measure a wheels set over from both sides before cutting spokes off, if you put new rim and spokes on rebuilt hub, with very same set over, it's just get to be right, much better than having to ask complete strangers if they might know on any amount of sites and forums?
I bought my cast iron "Wheel truer 2000" wheel building jig from a man on a stall at Beaulieu Autojumble about ten years ago, I gave him £8 for it, he then asked what it was! When I told him he seemed quite upset at selling it at such a low price, but to him it was a lump of scrap iron before. I started building bicycle wheels when I was about 15, I read somewhere that the spokes are not pulling on the hub, no, the hub is being suspended by the spokes and rim, so I wanted to prove such an unlikely statement could be true, there can be no other of course. Including push bikes and mopeds, done about 20 or 25 sets now, did my B175 ones two weeks ago, takes about 20 mins to get spokes in, another half or three quarters of an hour to get rim straight and correct set over.
