I think you should discuss beading with him and take his lead if he believes in beads do it if he says weights do it...why because if that doesn't work then you have one more option...the reason I say that is once the beads are in the tube removing them if results were not to your liking would be awkward. Just thinking out loud. Just to be clear my bead experience is so far positive.
I'm not sure anyone with a "tech" in their job title should be allowed near vintage cars or their components.
My apologies Replace that with Vintage Tire Specialist... @modified show him those 2 vids I posted it seems it may be a shave with polishing...I'm just curious. Maybe take a video if possible. By the way are you running tubes?
I really want to try the DynaBeads, I hate the look of weights on an open wheel car. I would think that the beads would help balance the whole rotating assembly if they truly work! I have buddies who run the beads in all their vehicles and swear by them ! Sent from my SM-N900V using The H.A.M.B. mobile app
With out of round tires, you rotate the tire on the steel rim so that the out of round wheel balances out the out of round tire.....the match balance machine figures that out. In other words, the high spot on the tire is mounted 180 degrees to the high spot on the rim. With machined aluminum wheels they are 100% round, so there is no high spot to offset the tire to.
I had the very same modified car and the problem was the wire wheels, I put solid wheels and it was fixed. Wires flex and bend easily.
Back in the day (50s, early 60s) dad always bought recap tires. I used to love watching the tire shop mount the tires and run them thru the shaving machine to true-up the tread. I was kind of scared they would shave off too much and the tire would explode but still fun to watch. That process is relegated to truing up recaps I suspect. Tire tech on new tires is way advanced from those early days. One caution with running vintage tires. I used to think tire shops refusing to work on tires over 5 yrs old was just to peddle new tires. After this happened to a new/old tire from the trailer I bought to transport my Mysterion, I have a new respect for the time limit on tire life. This one had never been on the road, always inside the trailer as a spare. I had it sitting in the Bakersfield summer sun while I was refinishing the trailer interior when I found it like this one morning.
I am no tire expert but shaving is a process that was used in a industry of lesser than round. Man overcoming mold or process that produced out of round. It really was for all tires of that era...recaps included. We are lumping Bias plys in the same Dot as radials...they are different types of tires... I am going to find some data. This whole industry is like one big hyperbole of confusion starting right from Coker saying no to shaving. Your selling period and saying No to its tools. And hey let's not forget the tires are lovingly made in the same molds the same way. That to be clear is not saying every Bias Ply they make needs shaving either.
Really interesting discussion on this subject. My wife's flatty powered truck has had a balance/shake problem forever. Since we first put it on the road in 2003 it had the problem. We have stock '35 wires on all four corners, '40 brakes and pretty much standard hot rod '30 chassis. It's on it's third set of tires, we've tried bias ply as well as radials and it still shakes (worse at 55-58 mph). I have an old fashioned bubble balancer on order now. I'm going to give that a shot and try to balance the rim and the brake drums as a unit since everything seems to run round & true. Hey, you can't fault gravity right?? ........."film at 11:00"
@Retrorod if you exhaust all balance methods and it still doesn't feel right consider Beads for Antique Autos...and again I have no affiliation with any of these companies. I still would shave them IF I find a source and am still trying to achieve better but I'm now okay with what I have achieved even if the other things don't make it better if they do I will report the change good or bad...
So "modified", you didn't answer my question. Have you made sure the brake drums and wheels are round and true before this shaving process or are you just attempting to ignore any potential underlying issues or problems in hopes of not having to spend any money on the car ?
TTR being mechanically inclined but not a vehicle mechanic is this an tire off dial indicator against the drum check? Also while I am thinking out loud and much younger vintage than this style of hubcap what's the best method of non maliciously removing them...thanks in advance. As simplistic as these primitive cars are I'm sure that's just one of the many checks...as I'm sure it would also be check wheel and tire on car as well so there is 2 more checks...
Stogy, that's just one of several methods or steps... ...in a process of elimination, in which all should be performed in appropriate order if attempting to pinpoint the culprit. Best method can be an interpretation or an opinion dependent on individual case/event/person/etc.
I own both a tire truer and the strobe balancer. I am located in Reno NV and have fixed many problems that couldn't be fixed by other people. I have experience with tons of hot rods and race cars. Sometimes the old ways are still the best. By the way our streamliner averaged 415mph in the 4 mile this August at Speedweek.
First of Congrats on darn near being a Jet with no wings...You fellas provided lots of entertainment for us this year... @NV rodr when you say truer are you saying shave machine or is this a form of weight balance? I posted two videos of the same shop performing shaving and another doing a strobe high speed process. Nobody has offered an explanation to what they are doing with the 2nd process. https://www.jalopyjournal.com/forum/threads/tire-truing-or-shaving.1119782/page-4#post-12714484 Here... We have a thread on Shaving Registry to help the membership find the right people. You should offer your shop location as many members all over North America need these problems addressed.
Off and on, I've been ruminating on this concept, to wit, a competent hot rodder from any era who said to himself and/or his buddies, "I'm going to spend some of my hot rod budget buying this piece of shit to put on my car to prove that I'm a REAL hot rodder"....
I installed the DynaBeads this afternoon 8/31/18 and off to the shaver tomorrow morning! Sent from my SM-N900V using The H.A.M.B. mobile app
I dropped a bit of those on the floor first tire...just a little and they were all over......little buggers. Hey I was out for a little cruise today and yeah it is quite smooth right through the range right up to near 60mph today with the beads...I used to have a couple of bouncy points that are now gone. I'm pretty confident your gonna have real good news...Thumbs Up...
He can let the fella know its only 4 ounces approx per tube and the tires are pumped up to say 26. Its a slow rpm process Shaving and I don't think the beads will affect the process. When you spin balance yes they will work immediately as they disperse with centrifugal force. The other thing is the Tire Specialist uses Dyna beads all the time and may have recommended it.
Question, Are those resent purchases, or have you had them for a while?Reason i asked is i tried to find a truing and strobe balancer to purchase and couldn't.
I'm just a guy who couldn't find anyone competent enough to figure out how to fix my problem. So I searched for the best old equipment I could find and spent countless hours finding out how to get the results using the old way. Problem is that it takes real time to fix the issue. That doesn't play well to an audience that wants a machine to spit out a number and a location to stick it. In fact, the strobe balancer won't even give you a number in ounces of lead to use, but when you figure it out it is as good as it gets. Probably a result of balancing the entire rotating assembly( tire,wheel, and drum). Then the wheel is indexed to a stud and kept that way until a new tire is used. As for shaving down the high spot on the tire, there is a learning curve. I take off as little as I possibly can, but I let a friend use it once and watched him leave thousands of miles worth of rubber on my shop floor because he just didn't have the same feel. Suffice it to say , both these machines are only as good as the person operating them. There's no replacement for experience. You all will agree that should be left to a true craftsman.
Nope, I've owned them for almost 20 years. Try and find something currently made that will be working that many years from now.
Thanks Rodr so are those two videos showing the two machines you have? I'm just curious. There are many fellas here that require what you have come to know. Obviously location matters but for those that are within traveling distance of you your a valuable entity. That is of course if you do truing for others. I still am wondering what that second machine in the video is. It really looks like its smooths the tire at high speed and it also has a strobe light.
