'64 BSA Lightning Rocket - Cadmium Plating Hardware

The hardware on the Lightning Rocket was a bit rough. While much of the original bits were in their correct places, many had been moved to other spots or replaced. Most pieces had been removed and painted either black or gold. I wondered for a while why this had been done and realized that the Corunna Cavaliers, the local high school where the BSA spent its life, has black and gold for their school colors. Maybe the owner who hailed from the fine town of Vernon Michigan was a supporter? A plausible theory although we will probably never know. Go Cavaliers!

Some of the rusted bits that made disassembly a bit difficult. 

To my surprise much of the hardware was difficult to remove. Slight rust held things together while lock-tite or some different bond had been used in other places. A rather large number of fasteners had been replaced by course thread UNC nuts and bolts which were easy to identify. Some were metric with a British type flat head showing no markings. Dome headed UNC lock nuts were also put onto some of the bolts whether they were BSW, Metric or UNC. 

Boogered beyond repair or just plain wrong. 

Bits were cataloged as removed. The older BSA spares manuals are not as detailed as later ones and more notes had to be taken. Some of the pictures were not even a close match and appeared to show "home market" models and not the US version. The Lightning Rocket seems to have many parts in common with the older A10's and the Rocket Gold Star to be specific.  

Notes were taken to get the right bits back into their spot and an excel spreadsheet was kept noting what had to be hunted down. On our side of the pond the few Cadmium plating sources still in business charge by the pound and most have minimums. If you miss a nut or bolt it is difficult to get just one finished at a reasonable cost. Each time I send out a batch I add a few extras in case I lose something or a bit gets buggered. My lot ended up weighing about 31 pounds.

My order list taking shape....stuff to acquire before plating. 

I spend a lot of time prepping hardware to make sure results at the Cadmium plater will be good. The best way to have good luck with a process is to spend a lot of time making sure you will have good luck. Although I have developed a bit of a lengthy process it seems to work well. 

All hardware is cleaned by de-greasing it in a crock pot. I found one rectangular in shape which just fits my axles. Once all hardware is de-greased it is inspected and repaired as needed. Filing flats, fixing Pozi drive impressions, and chasing threads as needed. Axles go into a lathe for filing and polishing as most have had channel locks violate them at some point in their life. Many bits end up in the lathe and if I had one machine tool in my shop it would be just that. I have been using my father in-laws lathe. It is an old "Wardmaster" made by Logan of Chicago and fits the bill quite well. 

Bolts boiling in my crock pot. I use Simple Green de-greaser and water to assist cleaning. 

The lathe is my friend and we work together often. I am polishing an axle in these photos. 

Distorted metal is moved back into Pozi drive heads and then a Pozi bit reforms them. 

Missing bits must be replaced. I can purchase BSC bolts with flat heads but I don't have a source for domed bits. I make them by reshaping flat headed bits with a form tool. 

Once all bits are compiled I soak hardware in white vinegar for a week. This removes the original CAD plating and zinc plating from recently manufactured replacement bits. 

After stripping hardware in vinegar it is soaked in baking soda and water for 15 minutes to neutralize the acid.  Rinsing with boiling water provides a final cleaning and evaporates moisture before rust sets in. 

The final step in prepping hardware for Cad plating is bead blasting. I have made various simple fixtures to prevent losing bits in the blaster. I still have to sift sand when finished to find errant pieces. 

My bead blasting setup rolled outside to keep abrasive from covering the contents of my garage. Don't laugh, it works quite well. 

The last piece acquired from Dotler MC on ebay. A NOS front brake cam with its antique part number and a price of $2.75 still taped to it.....I paid a bit more and was happy to get it!

About 30 pounds of hardware heading to the Cadmium plating source in Plymouth, Michigan. It will be hand delivered and picked up to prevent being "lost in the mail". 

The hardware is one of those rather fiddley things that requires the appropriate amount of attention and I put a lot of effort into this task. It's the attention to details that make a bike stand out from others. Hardware plays a large part in achieving a high quality result. 

 

Back from Plymouth Plating Works and looking fine. Let the sortin' begin!

After going to its only show this year and bombing around back roads a bit the Hornet is back in its safe place. It really takes off at 4000 RPM with its open pipes and is a blast to ride.
