Tire Install Heading to Plan Z

It took the 3M 5200 Marine Adhesive a full 7 days to set up.  By set up I mean that it still felt tacky, but also felt dry and I really had to push to leave a fingerprint.  Getting antsy, I put the tire on the rim.


That was easy enough, but putting air in was another story.  My small 3 gallon compressor was no match for the task at hand.  So, off to the neighborhood Independent motorcycle shop I went. Explained to them what I wanted and they said sure they would air it up.  Pulled around back and was looking forward to having this part of the experiment done.  But, there is always a but, the tire is so stiff that it wouldn't push up to the bead.  We used a ratchet strap to try to compress it and that didn't work either.  Even with a 100 gallon compressor there was to big of a gap between the tire and rim to set the bead.

So, with Plans A and B not being unsuccessful it was time to re-evaluate options. Sometimes you have to dig deep when you are hard headed.  That brings me to Plan Z.  You know about Plan Z?  That is the what the hell am I going to do now plan.  The am I a quitter plan or am I really a risk taker plan. Being me, if this is going to fail it is going to fail big.  Not just fail big, but I am going to show just how it failed.  This is Wednesday morning and I have several necessary things I have to get done today and might not to get to Plan Z today, but I will post about it no matter the results.

Somehow the comments link got changed.  It should be fixed and comments can be left again.  Sorry for the inconvenience.

Thanks Barry for alerting me.

Tubeless Spokes...Past the Point of No Return

People say it works.  Others say it is crazy and they would never do it.  Me, I'm a risk taker, and being able to plug and air a flat in some remote location sounds a lot better than worrying about a flatbed coming to get me.  So, I took the plunge!

First order of business was having the new 16" x 3.5"  rim respoked and trued. I opted to have the Wheel Shop do this because the cost didn't come close to the effort and chance of me not doing it correctly.  Picked it up Thursday morning, gathered the necessary supplies, and set up shop on my mobil workbench.
  
 Respoked rim and step 1 Seal All and a bottle to control the application.


 First step is to put Seal All into the spoke indentations.  I did 4 - 5 at a time and waited about 5 minutes to go to the next 4 - 5, just long enough for the Seal All to not run.  Being careful to not get big air bubbles because that is where leaks come from. 

I let coat one set up, about 45 minutes and proceeded to coat 2.  Same procedure as Step 1.  There are many small air bubbles in coat 2, but it is said that this isn't an issue.  I let this dry from Thursday early afternoon until noon Sunday.

Next coat is with 3M Marine 5200 Adhesive.  I found where some people have used only this and swear by it.  Because it is thicker than Seal All I choose to use the Seal All first with the hope it will seal better around the spoke nipples. 


Lesson I learned with the 5200 is it goes a lot further than I expected it to go.  I bought 2 tubes and used less than a quarter of 1 tube.  I cut down a plastic putty knife to fit the shape of the rim and it pushed a lot of the sealant up the rim edges.  I than put a bead just down the center and it worked a lot better.  There is no hurry with this sealant as it is slow drying.  My plan is to put another coat over this one in about 3 hours and then let it dry for 72 hours before mounting the tire.

So, now I am past the point of no return.  If it works I will be thrilled. If it doesn't work I guess I can still put a tube in it.  Balancing it has popped into my mind as I was sealing the spokes.  I plan on using Dyna Beads. To that end I also picked up a new rim strip to cover the adhesive because the Dyna Beads are free floating inside the tire.  I'm not sure how abrasive that is, so the rim strip is for an extra layer of protection.

Up Date;  The 3m 5200 didn't set up as quickly as I had hoped.  It was still to tacky to add the final coat until Monday evening.  I then put on what I hope is the final coat and it went pretty much just like the first.
                  

I about drove myself crazy trying to make it perfect and finally said good enough.  So, it sits in the garage drying.  I will sit it outside in the sun for the next couple of days to speed up the drying process and hopefully will be able to mount the tire on Saturday.

The Learning Curve Continues

Spent some quality time in the garage today learning about lacing a spoke rim. Sounds simple enough to put a spoke in a hole, stick it in the rim hole, start the nipple, count four holes, and go the next one.  Then flip the rim and repeat.
This was the result of that flawed thinking.

It seems that I used the wrong holes on the first side and that made the spokes way to long for what I had hoped to accomplish.  Looking and thinking about it I made an adjustment that appeared to lead to a solution.  However when I tried to straighten out my mistake I mixed up the spokes and that wouldn't work out to help me measure for the correct size spokes needed.

 It did allow me to be able to mount the 4" rim to Petunia and check for clearance for the brake caliper. Looking from the rear you should be able to see the hub isn't centered because it moved as I was mounting it to the axel.

 Looking from the right side there is clearance for the brake caliper, but I'm going with the 3 1/2" rim to not push the issue.  That and half an inch narrower rim will result in a narrower tire.  Still searching for those little numbers.  On the left side I'm pretty sure it shows that I will be changing to a 1' drive belt. 

At this point needing to order an unknown size spoke and worrying about being able to correctly true the rim I called a favorite local tire shop.  They would furnish new spokes, lace, and true the rim for only $125.  It took just over an hour to get there, drop off the rim with hub, and get back home. When I was leaving Steve told me it could be a day or two to be finished.  Here it is three hours later and he called to say the rim is ready to be picked up.  I'm pretty happy with my decision to have them True the rim for me.  

Next up is sealing the rim to allow for running a tubeless tire.

Finally Back To Installing The Car Tire On Petunia

Spring has sprung out here in the desert, I'm 8 months into my time out, and getting itchy.  So, into the garage to start to piddle because I will be able to ride again before long and don't want to not be ready.

This is the first tire I have changed.

 Success, with minimal effort.

 This is the rim strip that I paid to have changed 1,000 miles ago?  Looks like it hasn't been changed in forever.  I have been charged for a rim strip every tire change in the 9 years I've owned Petunia.  Makes me wonder how many tubes I've paid for and didn't get.  This strip was so brittle that it took very little  effort to snap it in two when pulling on it. Plus it was stuck to the rim and I had to cut it to get it loose.

 Test fitting the new tire under the fender.

 View from the rear. Looks like room to me.

 I took the fender all the way off to get better measurements and found this lovely crack that will have to be repaired.  I'm going to replace/cut down the mounting hardware and massage the fender a touch wider to make a little extra room.  I read somewhere that it was the little numbers that counted most.

I have unlaced the 3" rim from the hub and will will test fit the old spokes into the new rim to be sure they are the correct size.  I will then order a new set of spokes.  While waiting for them to get here I will mock up/lace a 3.5' rim and a 4" rim to see which one fits best in the area I am confined to.  This little extra work will help me determine the need to go to a 1" drive belt, which I am thinking will be a necessity,  and checking actual clearance of the brake caliper.

Doing the impossible takes a little longer, but if this works out getting 25,000 plus miles out of a rear tire sounds good to me.
