I am well familiar with him joints having them as the mounts on my sidecar and using them as the conections for my shifter linkage but I feal like that would have more play than this piece from jpcycles.  Trying to fall asleep last night I had a thought and may see if I can get a maching shop to throw a bolt in there lathe and bore a hole for a cable to go threw and then a step up on one end to let the fural sit in the bolt

I found a break cable from a cm250 with a front drum break is about 4' long and will have some stays made up buy a friend who has access to a machine shop.  Then I just need a cleaves that I can put on the leaver side of the cable

Mantree,

I am glad that despite the conditions of the inherited frame, you are undertaking a proper repair.

The stock Honda frame is only 1/16 inch thick, about .062 thousandths of an inch.

If you weld on a tube frame try not to make transverse welds if they are not needed.
To put a patch on a frame that is 1/16 inch thick use a TIG welder.
You want the lowest heat input.

All of the metal needs to be CLEAN.
Do NOT use a grinding wheel on a frame! IT is too severe.
 It will remove too much metal. Just use a scotch write pad. Maybe a little paint stripper .

I had a professional weld it for me I used a during wheel to take off the tab then used a flap wheel to clean the old welds  sand paper to clean anything left then Tim cut a plug and welded it in.  I trust his welds over any other he actually did my sidecar mounts on another bike and  taught me to tig

What you need on your controls seems to be fairly simple and straightforward.
 But without pics , really hard to help.
Had you posted clear pics in the beginning, we could have helped you thru quickly.
While finding a solution is the main goal, finding an elegant solution, that fits in nicely and compliments the bike.....is even better..

Well I have templates for the bracket for the forward controlls mounts I'll get a copy of the template up soon and I have a dissing for a clevis that I will be making out of aluminum stock that will let me just slide the end of the cable in so if the cable needs replaced at any point it's simple to just pick up a replacment cable from anyone that sells honda cables.  I have a guy making me a sissybar and he said he will machine me some cable stays using round stock welded to some plate like  this

Then I am going to order some cable clamps off j&p to hold the cable to the frame

Machined ? Looks like he just cut a piece of pretty thin tubing and welded it on..
It should fit nicely to the part that is inside it, and have a slot to get the cable in and out....

So sissy bar on new regulator rectifire unit on the way, new barrier blocks coming to clean up the flying spaghetti monster in the headlight bucket and a starter solinoid so that I can get my electric start back.  Still no progress on the forward controlls yet

Nice.

I always like to see bikes with Konged frames, they make me feel so much better about the comparatively much milder mods I made to mine :)

Also, tell me more about those bars please.

The bike was chopped up by my uncle in the late 70s.  The handlebars are called window handlebars they are a set of stock bars with what are esentaly welded on risers I'll try to grab some pictures when I get home tomorrow morning.

Oooh, I get it now, my eyes were playing tricks on me with regards to how they were mounted. 

It's very cool that you know the history of the bike and you're keeping it on the road after all these years.

Got my new regulator rectifier and installed a new plug wired on.  It will be mounted under the battery box.

Nice and clean looking.  Well done.

Although, I personally have developed a deep dislike of that style of split loom and instead switched over to the braided expandable stuff.  You'd need to put it on before the connector, though, or else pull the pins out of it to feed the wire through.

Thank you. I only used this because I have a mountain of it from my old job.  I wanted to use these
