Bubbling Beneath The Surface...











The past ten days have been a roller-coaster ride of highs n’ lows; my illustrator, Michael J Murphy has brought the main characters in my series of children’s stories alive as Jpegs. 

Given digital media dominates and portable devices have become the viewing tools of choice; we’re considering releasing a narrated version for younger children.

In keeping with our everyday focus at Seven Day Cyclist (www.sevendaycyclist.com    https://www.facebook.com/Sevendaycyclistmagazine/?ref=aymt_homepage_panel ), we’re awaiting delivery of an interesting trailer or two.
Some of the team are leaving their wives behind and heading off for a quick gander at the Czech Republic...

My strange and some would say; irrational love of crumbling Soviet military/industrial sites, coupled with an uncanny ability to get arrested, detained and interrogated by the authorities means I’ll be testing kit on domestic soil through June…

A recent dry spell enabled me to slather some of my home brewed waxy preserve over the KA’s chassis and underside. 

Build quality seems an improvement over its predecessors, suggesting there’s some truth in the long held belief that last-of-the line cars were the ones to go for, since all the faults had been ironed out. That said; rust behind the filler cap remains as problematic as ever.

Moisture gets trapped between the rubberised seal and bodywork. A distinct lack of galvanising means the elements nibble away unsupervised until the bubbling becomes apparent. Thankfully, remedial action wasn’t too intensive. 

Having removed any flaking paint, I sanded the affected area; then added two light coats of Krust; a water-based neutralising agent before turning my attentions to my two-wheeled fleet while it cured.

Some minor play had crept back into the Holdsworth’s headset bearings, swiftly cured by a quick bit of spacer shuffling and introducing a 2mm “carbon” unit beneath the stem cap. 

Forty miles hence, suggests this unexpected flash of inspiration has solved the problem. 

WD40 water displacer is one of those truly iconic products; look in any household cupboard, garage, bike shop and chances are, you’ll find the blue aerosol (or 5 litre solution) sitting on a shelf/workbench.It’s not particularly kind to seals and other rubberised parts but inhibits corrosion, prevents squeaks, lubricates cables, pivot points, mechanisms etc. 

GT85 is another justly popular, Teflon fortified maintenance spray, which keeps these areas slicker for longer. It’s also owned by WD40 and they’ve also launched a bike specific GT85 range including bike wash, dry lube, degreaser and silicone polish.

While my preference (and that of many bicycle/motorcycle dealerships) errs towards high quality beeswax furniture polishes; dirt cheap, they achieve high quality, lasting sheens on painted, plated and polished surfaces with minimal effort. Silicone products also nourish plastics and rubberised components-suspension elastomers, seals being obvious candidates.

Traditionally, silicone based polishes-bike specific, or otherwise have tended to quickly cultivate grimy patinas. Credit where it’s due, while this formula still seduces some filmy grime, it is easily dismissed (almost as quickly as these U-locks) given a quick, soft-cloth onceover, though the lion’s share of protectant remains. Looking forward to putting the rest of their range through its paces...

John Moss is another perpetual fettler, perhaps unsurprising given his engineering career. In common with coach-builders and other engineering grade trades I’ve encountered in the past, he’s been trained to discover weaknesses and improve designs accordingly. His Mango being a prime example; Alfine 11sped hub, much bigger ring instated, gearing now permits 35mph at modest cadences and theoretically in excess of 80mph on a long descent!

Richard Ballantine once suggested that having motorcycle experience can be very beneficial when pushing recumbents hard-I was somewhat smitten with his “Speedy” during this period and would certainly indulge today...Along with some kind of 850cc trike project if other priorities and space permitted.

John affirmed that his ten years spent riding large capacity motorcycles develops an intuitive understanding of exactly when to push and of course, to back off.  He’s also learning to work with glass fibre and appears to have commandeered the couple’s trailer for solo shopping runs and other errands. The hitch is presently undergoing refinement so it tracks more accurately behind the Mango...   

Back to the KA

Next came three light coats of red oxide primer. Ideally a colour coat would’ve been applied but in my experience, these will keep the region solid and grot free. Before reinstating the filler cap assembly, introduce some decent quality, rubber friendly grease to the seal. It won’t cure the problem but greatly inhibits further bouts of grot and therefore, more intensive exorcism.

If you’ve bought a late model MK1 with no signs of corrosion in this region, I’d recommend a similar strip-out before filler and more serious intervention’s needed...
