Hi Merv. Yup, Si's right, the main site's been offline for a while now. We've got 5 year's worth of material to sort out & de-bug. We've repaired the forum & the Motors, 4 wheels page, plus a couple of recent event photo galleries, but we're currently running everything from Taz's laptop computer, which has a very limited memory, like me, so that's about all it can handle. When things crashed, we lost a lot of photos that had been posted on the forum up till that date. If anyone posted & still has their pics, please edit your posts & add them back in by the way.
Although we disabled the main site by removing the link to the homepage to protect our readers from the viruses we'd contracted, some people had us saved in their favourites list as pages other than the homepage. So it's still possible to find the main site through other means. We've not had any reports of virus problems.
So, to answer your question Merv, the Reliant hubs are square, whereas the Nova disc centres are round, so you need to take the corners off, either with an angle grinder or in a lathe. The centre hole of the disc is also slightly smaller than the raised centre boss of the hub. So you need to machine the hub down a little until it's a snug fit. The hub is softer than the disc & so easier to machine, plus, if you machined the disc & ever had to replace it, you'd have to machine the replacement as well. The disc centres itself on this raised centre boss, not the wheel studs, so it needs to be machined reasonably accurately. Not a big job to anyone versed in the ways of lathe work.
Oh, & welcome to the forum by the way!
