If its cheaper than spinning a new rod, consider the cheap harbor freight balance stand that comes with two tapered adjustable pieces (look like a stepped drill bit, only smooth) and use with the rod you have. The HF stand is passable but its almost certain that the rod they ship with will not be straight.  I cut my own replacement rod and used the rest as is, worked out ok.

Dang! So that's what those two pieces are for! Its been so long since I'd used the stand I forgot what everything was for.  Mine are 2 cones with set screws in them to hold them in place up against the hub bearings.

Thanks!      

[edwardmorris]

Yep

Those set screws are a pain to get it to hold still, so I threw them out and used pan heads that were the correct pitch, but a bit too long. Worked out ok,

[MCRider]

The first truing balancing stand I ever had, the standards would move together far enough that you could use the axle on the balance bearings. Somehow, somewhere that stand got away from me.

Mine (PitBull) is more like yours, with the standards wide apart and only a couple of small adjustment holes. 

Some beefier screws would work  better than the allens. Holding those cones up snug to the hub bearings is the key.

I have a balance stand only similar to what both of you have & I'd like to turn it into a truing stand also.I have a bicycle truing stand which will accept rims up to 5" wide max.Could you give me a close up picture of what the trueing parts of the stands look like so I might consider adapting them to my M/C balance stand ?

A few for fun. Out of order:
Yes, it actually has miles on it.

By this guy:

Will this count for the "your bike on the road" thread?  It's smokeless, yay!


A mystery leak, starts from the finger to the teminal spot on the right. We glued up the screw and gasket with Gasgacinch:


Bought some chrome caps for allen heads, from a place in China. Came tied in bows with a polite personal letter.

It won't smoke Ron.. ...especially if you take it to the dyno and set the rings etc real good.....I guarantee it. That engine will run better and better as miles are amassed. You did it right and I have to say sending those parts to me is part of the equation. Relax brother.

Thanks Mike, I agree. IF 70 miles is anything to judge, it's going to be a great motor. The 888 I had before was a great motor. This one has better parts and machine work, and machinist work.

I have to admit I was inadvertently sloppy on the bottom end assembly, especially as to sealing the cases and main bearing studs. But if I have to pull it to fix that, I can do it without disturbing the top end.

Looking forward to the Dyno this year and the drags when they open in the spring. After that maybe we can arrange for a longer "tour" somewhere.  Make a little scrapbook for the "Legacy". I may or may not ever do another project, but this one is the Legacy. I posted this before, so pardon the repeat: I had a visitor over for another subject a few weeks ago. He saw Phaedrus on the trailer and said: "Where have I seen that bike before?" He remembered it from somebody else's facebook page. Pretty cool, the next 30 minutes was on Phaedrus, and not what he'd come for.

When I talk to others about the bike and the engine, I like telling people, "I sent the top end out to a Specialist in Boston". Thanks!

ok thanks Ron.
I want to see how they adapt the truing fixtures to the uprights and then what type they are;also want see what keeps the wheel locked in place so the axle can't move side to side when I'm truing it and the rim makes contact w/ the 'feeler's',etc.

If you click on the pic in the link I gave, you'll see it. The top shaft with the cones is for balancing. More room for the tire.

The screw ins down below the top shaft, also with shorter cones, is for truing. No tire. You run the smaller cones directly into the hub bearings, firmly but not nuts. The standards are quite stout at that point, and everything is held firmly. USe the pointer and any other method you want for truuing like a magnetic dial indicator.

Yes,I looked at the pic in the link;do you have any other personal pics of your stand ?

I'll get a couple.

Here you go.







Any view I missed? 

[grcamna2]

No,you've got it covered this time ! thanks 
those upper large threaded parts that seem to push? on both discs are interesting...
What do you do w/ a drum wheel ? if you didn't use them would the wheel still sit down well into the upper mounts & keep from moving side to side if you used a light touch on the pointer ? I like that adjustable pointer also and it gives me some ideas of how I can adapt one to my 'balance only stand' even w/o the upper threaded 'stabilizers' for the dual disc wheels.I'd sure need to use a gradual light touch w/ that pointer so I wouldn't defeat the purpose of the truing.
 I find it works best for me to go slow when truing a wheel to get it just the way I like it,especially w/ the up & down 'full circumference Round' truing which takes lots of work to get exactly 'Round' all the way around the full wheel,I get the side to side done first and then do the bigger task of the up and down 'hop' (w/o the tire installed) and keep checking the side to side after every 'up and down' adjustment;it takes a while but well worth it. 

[MCRider]

I see your confusion. If you are balancing a wheel, the the "large threaded parts that seem to push on the disc" are ignored. If you are truing a wheel, you ignore the rod and bearings at the top of the standards and run the "large threaded parts" into the hub bearings.

The rig at the top is for balancing only. Withdraw the rod and allow the wheel to drop down to the "large threaded parts" and run them into the hub bearings, for truing.

There is no double disc stabilizer effect. Thats a mis look.  In other words, my wheel is set in the balancing position.. I'll get a pic tonight of it in the truing position.

The rig works perfectly fine on a drum wheel. I did my rear on the same stand.

[grcamna2]

ok,I See    Now...    The threaded parts thread in to the axle hole on your wheel along w/ the cones? to adjust the position of the wheel where ever you want to 'center' it depending on the width of your hubs;nice design ! I don't think that I'd be able to adapt all that machinery to my 'balance only' stand  . I'll need to find a M/C style truing stand w/ adjustments for different size/width wheels to fit the task best !

[754]

The trick to using the tapered cones is to first have a good screw, second, put a piece of plastic, brass or aluminum rod in the hole, so that the screw is not biting into the shaft, every place you tighten it..

That's right. This design for a stand is about as basic as it gets. You'll spend a lot more to get one that can offset the rim on the hub, and do fancy tricks. This one will do it, but its up to the operator to make it work.

[754]

Change your rods to Plastic. If you can't find rods use knitting needles, swizzle stix..  Something that cannot scratch.

Good point and idea.

When I true, the tire is off and I put the pointer on the bead inside of the rim, so scratching is not a problem

Shop time pre-empted by family visits. Got some shopping done, chrome nuts, vent hoses, bits, did some deep cleaning. Amazing number of dead crickets in every corner.

VJMC Annual meet in Pigeon Forge, TN; June 25th. Hope to have everything done by then. full break in, dyno, dragstrip, local trips for photo ops. Don't know if I'll be up for a 7 hour pull. Hard to stay in a seat that long, even with breaks. We'll see. Lots of local stuff if not.

[MCRider]

It was a pleasant afternoon in the shop. For those of you who may not been on board at the time, let me repeat how awesome infrared heaters are! ITs the difference between the feeling I don't want to go out in the shop its cold; to Can't wait to get out in the shop. 30° becomes 65° in no time, quietly and efficiently. Everything you touch, usually metal, is warm.

Well it is cold and riding days may be few for a while. In the meantime, loose ends.

Seems I hadn't installed a vent tube on the top of the tank. So, we tied the cam cover tube to the oil tank tube with a T and ran it to the totally irrelevant, but chrome, breather.



Drained the tank to get a handle on how much gas there was. Also monitor the flow. Seems the reserve was real slow and only about .5 gal came out, after the main tank went dry at about 1/2 gallon also, and after tilting it to get the most out. Seems I'll need to pull the cock and see if its clean. It is otherwise new.

Got the wheel set up on the stand to balance. Seen a seal puller before? I think this is one.

It worked as one anyway.
But it seems on closer inspection the rod/axle supplied with the stand is bent. The wheel won't balance properly. Poo! The stand I had before used the axle of the bike, no chance for this hs. I think I'll have Saldanas turn me a shaft the size of the axle. I need to have them mod the chainguard anyway.

Piddled here and there, not much else to see, but it was fun.     Next weekend marks the start of Holiday interruptions, but WE'll try to push ahead.

[MCRider]

Still waiting on time to get an axle made for my truing/balancing stand. In the meantime...

If one goes back to the earliest pages of this thread, we spent some time trying to decide where to mount some mighty Hecla Nautilus type horns. The goal was for this bike to have alll the goodies it never had in earlier incarnations, includingg some kick ass horns. Over time, I gave up on the horns in favor of some minihorns, like this:

These fitted up nicely, and sounded decent with relays beefing up the juice. But still I longed for a foghorn. After some rethinking it became clear that with some slightly longer brackets, the Nautilus horns would fitt in the same place the miis did.


They stick out a bit more, side on side. But the SOUND, my lord the SOUND. This is your father's Oldsmobile!


Hopefully I'll have time to take some tasks to the machine shop, to continue prep for Spring.

[grcamna2]

Ron,I Like those Horns;if you blow'em someone may be looking your way wondering where the car is    very Nice to wake up some of these 'texting' folks   

[MCRider]

Yea, the last we spoke of them was before you signed in to the Forum. So you may not have seen them. We couldn't find anywhere to mount them that wasn't too obnoxious, so I settled for the mini horns. Which look good and sound OK, loud but tinny. Dropping the Nautilus horns was a big disappointment.

Now, after simply looking at it a different way, they fit fine. A little large, but the sound is worth it. Now when I show it in a people's choice venue, I can draw some attention to combat the MadMax GL1000s of the world.
