Re: Calculating Balance Factors a simple example

Inspired by Brian Walker's original post I thought I'd have a go. The method seems crude (so skilled and exacting engineers such as Messrs Whiting and Falco should perhaps look away now) but with care you can get a good idea of where you are - and just as importantly http://forum.arielownersmcc.co.u...

Re: JP piston weight reduction

Ian, Inspired by a thread elsewhere I've had a go at finding the Balance Factor on one of my VB engines (circa 1956). With a (split skirt) +20thou piston inc pin and circlips weighing 596g, a conrod small end weight of 207g and a balance weight of 263g, the Balance Factor is about 58%. In a 1956 fra...

Re: Re: Daily Fixing and Riding Diary on a mainly Ariel 2018

Surely Basingstoke & "Dean"? (And don't talk about deer - a couple of months ago one jumped out and did £1500's of damage to our car and caused no end of insurance grief!)
But keep up the diary of adventures! MikeN.

Re: 1954 VB cam followers

Dear Ian, I've the "Owners Guide" for 1954-55 models in front of me and it states "Note - On certain series of engines a thin steel shim is used to centralise the cam levers by placing it on the lever spindle either at the back or front of the lever assembly". The engine exploded...

Re: Conversion of 1955 NH to single seat

Well Mr Birch, no replies from our learned friends - so I'll have a go. For about a decade in the late 70s/mid 80s I ran my 1956 NH (fitted with a VB engine) with such a mod. I'd found the dual seat just too hard for long journeys and so as I was doing 90 miles a day to and from work plus occasional...

Anti-vibration gloves for bikes

Dear all, Being old and arthritic, I find garden machinery like my chainsaw, hedge-cutter and especially my strimmer make my hands tingle after about half an hour, so I've bought a pair of the above to reduce it, and among the comments on the sellers websites one finds occasionally support for these...

Re: 23 tooth drive sprocket

Thanks Eero for the link to the VB stuff; now I'm the owner of a very nice barrel and piston that's much better than the one I was about to fit reline - and only £28! And also the crankcase and bottom end for £45 where the splines on the mainshaft are far better than mine! This was my first success ...
