Howdy Bruce,

As in heavier than John Healey's?!

My answer to that dilemma with the Red Rap after grimly grappling with a front lever tugging fruitlessly on some NOS concrete compositioned and riveted Ferodo's was to simply raise the coeficient of friction by fitting modern, longer bonded linings for $12/shoe from my local truck clutch/brake shop.

Supplied slightly thicker than stock to give latitude in radiusing, they are softer and effort required to stop with this 250lb'r aboard can be achieved with 2 fingers with excellent feel imparted by no more than a bridge plate affixed to the balance beam pivot. Ever the realist - and in a nod to Tom Gaynor's previous (logical) observations on the same subject - they're no match for the discs on your Buell, but in lieu of lacing up a 12 inch Grimeca twin leader to your hub, the best bang for the buck.

The outfit's name is Laycook (901 523 1418). Very much a black smithy type gig, no website, no formalities, no need to mention your application. Takes about 2 weeks. I keep stashes for my other machines in rotation.

I didn't check with Coventry Spares. But Stuart has graciously provided me with a set and I'll be installing them soon. I had Ferodo green linings bonded on and turned to the drum ID's and I have the KTB boomerang on the beam pivot bolt and the Doug Hollis plate stiffeners per http://www.vincentownersclub.co.uk/photos/showphoto.php?photo=2842 and http://www.vincentownersclub.co.uk/photos/showphoto.php/photo/2843, so the cables will be the icing on the cake. All fairly discrete non-standard features, although the long cable outer sheath diameter is mighty impressive.

cables for bikes make you're own.

flanders
i made all of the cables for my bikes.
you'll need ends, ferralls, inner and outer cable and housing.

Making your Own Motorcycle Cables 1996

Some of us have experienced a pulled cable end, be it throttle, brake or clutch and our machines also have a compression release. It’s a bummer when this happens, especially at night, away from home. When building or restoring my bikes, going back to my 1st doodlebug (using electrical solder) and now my Rapides and R90/6RSS, I like to make my own cables, because they fit the bike. It is not an easy task but rewarding when done and working.
There are several distributors of cables, cable housings and fittings, with Flanders and Barnett my two of choice. I buy the universal throttle cables that have a factory made ‘ball’ @ the end. The rest of it has to be fitted to your machine. I also like to bend a ¼’’ radius tube to fit right at the carb top, so that notorious kink is eliminated altogether. Mikuni makes a very good rubber dust boot to help protect all cables from dirt. I also use black heat shrink to cover these boots as time and sun deteriorates them. These will fit at the adjusters as well. You can situate your adjuster where ever it is convenient for you. I use heavier cable for the clutch and brake assemblies and make both ends to fit.
Most store bought cables are made of 1 x (17 or 19) strand inner cable with sizes from .046 to .120, fitting mopeds to big bikes. The better inner cables are made of multiple strands referred to as a 7 x 7 cable, with seven groups of seven strands in each group, a total of 49 smaller strands. These are still about the same outside diameter size, (O.D.) wire so they will fit into your machine’s outer housing, should you wish to re-fit. The best part about these inner cables is their flexibility and tendency to work easier in a tighter bend radius. These are usually found in smaller diameters. I use a very high wattage old style soldering iron.
The outer housings are available in two types: lined with Teflon and unlined. The better outer cable housings are also made to be more flexible. They are made w/ more and smaller wire diameter spiral wraps for flexibility. Their size depends on the application and the inner cable sizes.
The other three parts to this work project are the outer cable ends, inline adjusters and inner cable end fittings usually made of brass. There are dozens of end fittings to anchor any number of combinations to fit levers and /or engine levers or rods. The outer end fittings are to make the housings look clean and provide proper fitting into the abutment. I like to grind the outer housing end flat after cutting it, using a sanding disc, and then insert an awl to clean up that inside spiral cable before I put on the outer cable end cap. Again the adjusters can be put where ever you like them for fine tuning.
The one item I have not mentioned yet is probably the most important, the solder. We have all used in a pinch not knowing any better the old standby solder readily found in our garages. Electrical 60/40 Tin-Antimony-Lead solder, plumbers solder made of 50/50 silver leadless or 60/40 tin-lead solder. Silver, Zinc, Indium and Cadmium are also used in combinations in the making of various solders; each has their pluses and minuses. Most of these are flux core solders but that does not mean you can not add your usual paste-flux to this process. These types of solders have a relatively low tensile strength of 4500-6000 psi. The MG product has 3x the tensile strength as these electrical types. Now just because the above plumbers silver leadless solder says silver, does not mean that it contains a good amount of silver content, maybe 6-9 % at most. Silver solder is by far the best way to join the fittings in this case, inner cables to brass fittings. There are many silver solders on the market, used for a multitude of purposes, most with heat ranges around 900-1400 F. degrees working temperatures. This depends on content and percentages of alloy material. This is too high for our use when cable making. Infact it is best NOT to use an open flame- torch on inner cables, but a very good soldering iron is needed. Some of you may have your soldering pots and used them for decades, and they work.
But silver solder does come in a lower temperature heat range for gas type torches without oxygen and iron use. This product‘s working temperature is 430 degrees, perfect for soldering iron use. I prefer this product MG120, also known as MG120A. These MG products use a flux core and cleaning agent for the preparation of bonding. The MG120A has a syringe applicator for the cleaning agent whereas the MG120 is a bottle. It is available at welding supply stores.
The key to a strong union is wetting and capillary attraction. Wetting is the ability of the molten solder to coat the strands surface. Capillary attraction is its ability to flow or wick. I prefer to ‘’tin’’ the inner cable end after I have slid my end fitting on to the inner cable first. This allows you to ‘’work over’’ /mushroom or flair the multiple ends more easily to prevent the dreaded pull-out. Pull the inner cable back to the fitting and solder. Trim or file the fittings when done.
Remember to lubricate all your non Teflon lined cables once a year by buying one of those simple spray type lubricators available at any good local m/c shop. I use a spray can of white lithium grease. These devices clamp over the outer cable end, have a small rubber hole built in and the grease squirts inside, down the cable housing through to the end. If you use a junction box with a single throttle cable to twin cables make sure you protect that junction from dirt and debris, clean and lube with light grease once a season along with all of your other cables.
Remember what Owsley Bear says ….… ‘‘They love to get out and play in the sunshine.’’

A good site, thanks!

I was recently had the good fortune to be taken, by John Crispin, to visit Marcus Bowden, the VOC Overseas Rep.
Marcus demonstrated the special tools he has made to '‘’work over’’ /mushroom or flair' the multiple ends. These comprise aluminium vice liners with a slight vertical groove to align the cable under a suitable counterbore and a hardened silver steel punch. The punch end is drilled and its bore and outer edge are rounded. Its bore is smaller than the full diameter of the cable but its inner radius lets it centre on the cable end. The cable is held with about five times its thickness above the floor of the counterbore. As the punch is tapped down the outer layers of wire bell out to meet the edges of the counterbore before their ends are tucked into the middle. The resulting tangled ball of wire hardly needs soldering as it would be impossible to pull it through a nipple. A separate punch and counterbore is needed for each size of inner cable. Perhaps if Marcus reads this he will put up some pictures of tools and wire ball end.

I will be making punches and clamp to make better clutch and lifter cables for myself and from choice would use ball shank ends (like Flanders 620-24280) in barrel nipples like (Flanders 620-23110) as they release any rotational stress from the cable.

Using a combination of Marcus’ and Jim’s techniques/advice, with a small solder pot to dip the fluxed ball end into, should give me better results than I have bodged in the past. The solder pot is used to ensure that no excess heat is applied to the cable as only heat transfer from the solder takes place.

I don't expect to ever need to replace the heavy duty front brake cables that Derek Sayers supplied.

Cheers,

VOCer Doug Wood has suggested a 1/2" NPT (or BSPT) black (un-galvanized) pipe cap http://www.marvelmetal.com/images/round-caps.jpg as a pot, to be heated with a propane torch. I forget how he holds it, other than with well-twisted heavy wire. The volume is nice and small, but big enough for a cable end.
