A Slippery Scapin's Starry Makeover

Increasingly superseded by stainless, chrome has long been synonymous with Italian manufacturers, despite Columbus recommending their tubesets were not subjected to acid baths, filing and similar torture...

Scapin are an Italian marque, renown for coating their steel frames internally with phosphate and nickel plating the exterior tubes. Allegedly, this was also for corrosion resistance, though I remain convinced aesthetics were the biggest pull. This particular example came under my radar, while I was mooching around Maldon Shot Blasting & Powder Coating’s bat-cave.

Closer inspection suggests it was fashioned from Columbus’ thin wall Nemo or Genius tubing. I strongly suspect it was originally part-painted like this Rossin but chemically stripped once the livery had begun losing its tenure and/or succumbing to stone chips and other cosmetic damage.   

Persuading stove enamel and 2pac finishes to stay put on partially/ plated framesets has presented headaches a plenty for paint-shops. Acid etch primers ruled by default but given a few years’, the livery tends to flake and peel where the two overlap.

This customer has chosen to leave the rear triangle in its original polished state. Aesthetics aside, this means chain slap and hasty wheel removals won’t leave unsightly calling cards. Graham carefully mummifies these with masking tape to rule out any pitting from blast media.

Having passed the threaded uni-crown forks through the iron oxide cabinet, Graham decides to sand the main triangle. He fears even a gentle grit could lift the nickel in places, which is not something that can be disguised with additional paint. 

Instead, he opts for an epoxy based zinc primer. Epoxy offers superior adhesion and interestingly, resists chemical attack better than others. However, they aren’t UV stable; hence polyester powder is the good finisher’s choice for colour coats.

After meticulous plugging and masking of head, seat tube and threaded areas, the frameset disappears beneath a powdery grey mist. Seven minutes and some perfectionist re-touching later, its spirited off for a ten minute bake in their gas oven.

Monitoring progress around the seven minute mark, the powder has melted to a rich (and strangely attractive) grey skin. Next; Graham applies a gloss black, a common “colour” that including lacquer brings the price to £65 plus VAT. However, this is only the base for a very exotic commission.

Four minutes and some localised re-touching later, its back to the curing oven for another ten minute bake; I alter the camera settings slightly and sip some tea, while Graham heaves a huge box of powder across the workshop dung beetle fashion. “Sapphire Star clear coat” he shouts over. 

I’m told this acrylic is impregnated with tiny pigments of colour. The overall effect is timeless petrol blue under normal lighting but assumes a subtle sparkle on sunny days. It’s well known that colours have slightly unique characteristics, requiring different techniques but Graham explains; particular care is needed with this kind of specialist clear coats-including temperature. 

The Scapin must not be allowed to cool, otherwise crazing or clouding is on the cards-disastrous. Gun loaded with lacquer, he strides purposefully over to the oven, caresses the frame tubes, nods with a grin and retrieves the frameset.  

Powder lacquers always appear white, enabling the sprayer to see exactly where they’ve been. Anything other than exacting coverage here will ruin the effect but like any skilled trade, he makes this look effortless-done in five minutes. 

Back to the oven for another ten minutes, we’ve time to indulge in a biscuit; or three. Graham removes the masking tape while the adhesive is still soft and I get a final shot.  

Total cost is £162 including VAT.      

 

    

Cometh December, Cometh The Dayglow

Drifting through to December brings with it the joys of day-glow. Prime examples to land at my door are these Proviz gloves and Altura night vision socks. At a whisker below £25, the former boast a windproof and water repellent laminated polyester exterior and micro fibre palm proliferated with silicone dots for a superlative, all conditions grip. The ubiquitous gel/foam ulnar padding is relatively low density, which works better for me, since the pronounced types are prone to inducing precisely the discomfort they were intended to alleviate. Thinner, wind blocking fabric makes for nimble fingers, enabling photo opportunities and less glamorous roadside puncture purges without necessitating removal. Speaking of which, they’ll resist heavy rain to the tune of thirty, maybe forty minutes-depending on how we’re defining cloudburst but mercifully, things stay toasty inside and there’s no danger of extracting a limp, soggy liner come the ed of an inclement training run. For the feet, Altura have taken their night vision concept to the logical, if slightly quirky conclusion. Available in warm orange (my preference) or the acid trip neon yellow, they’re made of common or garden Coolmax and do most things very well, albeit not on the same terms as Merino wool. However, the safety aspect works best with 3/4lengths which might not be everyone’s first choice in the depths of winter-although again, this is highly dependant on where you are in the world…
Those two frames have emerged from the curing ovens with new red and blue liveries. I’m still none the wiser as to their heritage but the suspected Holdsworth was badly nibbled, especially along the chain and seat stays, disguised by a thicker coat of powder since the customer was reluctant to foot the bill for more extensive filler-based preparation. Graham noticed some imperfections in the final colour coat induced by the seepage of residual oils languishing within the tubes. Fearing another trip through the blast cabinet would induce structural damage (even left softening in the stripping tank overnight) he addressed this by rubbing flat and introducing further, light coats, passing through the oven once more. John Doe’s chrome plate rear triangle and forks were of the lick and promise variety, vanishing with the introduction of gentle aluminium oxide particles. This was a moot point since the customer wasn’t looking to replicate the original effect and the parent metal gives a much better key for the colour coats.

A quick look around their holding bay gives an insight into the country’s wider mood. More and more people are having basic children’s frames refinished and passed to younger siblings. This is indicative of a very different mood that has replaced the buy new ethos for may working families frightened for their futures, economic and otherwise.

Elsewhere, I’ve been revisiting my series of children’s stories penned some years ago and aside from strengthening the characterisation, I’m hoping to generate sufficient publisher interest. Having seen my late father successfully publish several academic titles during the 1980s I am acutely aware of publisher resistance to “unproven” or previously unpublished authors but this is just a phenomenon I will have accept and ultimately overcome.
