Does this mean that Peter has to put rims on to the hubs to get the end plate(s) off, or has he devised a special jig/tool that holds the hub shell?

I used to manage with a few loose spokes into an old rim for this, and to remove freewheels from hubs where spokes had been chopped out.

Personally I always preferred gears in direct drive. Some 20 years ago I did try a Shimano 4 speed, which was a revelation compared to the Sturmey Archers.

Don’t know, he didn’t mention the lack of rim being a problem, hopefully he will reply (unless it’s a trade secret) :P

I think my dislike of SA started when I was repairing mainly AW in the 50s. The ones I saw were always full of what looked like rusty mud, where water entered behind the cog. Many utility bikes were left out in the rain, but were essential transport.
These were often old roadster types with rear facing ends and rod brakes.

For a 2 mile commute the bike was cheaper than walking.

Just remembered, I did have a K5 in the mid 60s on a 1935 Grubb recumbent. I also once built a wheel on a Dursley Petersen large flange 3 speed, the spoke holes are only present around 70% of the flange perimeter.

Will be happy to post some photos on here if people are interest. The 5 speed especially, it's an interesting bit of kit inside.

Having them laced into a wheel makes it slightly easier to remove the r.h. ball ring but if not I can usually remove them holding in one hand.
But yes, I do have a jig that can hold shells without damaging then. Had a few stubborn ones that required it but it's mostly used for removing l.h. ball cups on FM's and the like.

File comment: Old and older. 1956 on the right with a pitted left hand ball cup. We'll use the 1961 (left) as a donor. These older units used threaded cups. Later ones were press fit.

File comment: View of the compound planetary gear set. These are timed to the sun gears and only go on in one position. Clutch dogs are at the top and are machined onto the planet cage. This differs from the AW that uses the planet pins driven from the clutch.

File comment: Close up of the two sun gears mounted to the axle. There was a redesign of this in the S5.2 model. The gears are locked to the shaft via either the splines (top) or the dog ring (bottom) depending on the position of the left shifter. Unlike the FW, the S5 with its second shifter allows the hub to engage the wide range overdrive (gear 5). Gears 1-4 are as per the FW.
