After 20 miles on the shrink wrap over the king pins it look brand new still.
Also no torn up bushings you just need a shrink wrap a heat gun or Bic lighter.
Be care full on the Bic lighter method you can burn your finger on the hot heat shield.
I use a old heat gun I have left over when I was trying to make body boards.

How Do All Wink

I have been using the heat shrink method described by Terry.
I am using Holey Pink Bubblegum Bushings in my Bennett 5.0 and Skennett, I had to use a little grease to help tease them over the heat shrink as they fit really neat.
after a few miles on this set up I can confirm that there is no shredding an either the bushing or the heat shrink.

Thanks for the tip Terry.

Take care,
Barry Wink

Update!
After riding Umpteen miles with Eric on Saturday, and I mean Umpteen Eric inspected my Bushings, and both the heat shrink tube and top cone bushing had shredded pretty bad but not so bad as to thrash another Umpteen miles on them, Note: I had only been using this set up for a week.
I will not be using the Heatshrink again, it is not upto the sort of abuse I like to meter out Very Happy

I will however be using Eric's ali tube trick. which on his month old bushings showed very little wear at all, nice one Eric.

Take care,
Barry

That to bad the shrink wrap does not work for you. I only have it on the front truck of both a 4.3 Bennett with triple bushing set up. I also have the same set up on a Tracker RTX. I do take my trucks apart after about every 30 miles to check the the shrink wrap and the bennett truck shrink wrap breaks down or be come torn the RTX does not.
But I have about 200 yards of heavy duty shrink wrap I used on body board leashes I was making back awhile ago. The black shrink wrap is 1-mm in thickness and is 25-mm flat before I shrink it on the kingpin with my heat gun.
I just took both hangers off and I noticed that the Bennett truck hanger hole is 19-mm across tracker RTX hanger hole is 15-mm across.
I don't know if that has any thing to do with the shredding problem.

Plus I grind down all my first cone bushing till the pivot sit all the way down in the base plate pivot cup. Because I grind it down to fit the king pin is not scraping back and forth on the hanger hole because it's also centered.
I had to grind down the first bushing on the bennett truck to 8-mm thick and the tracker down to 4-mm thick so the pivot would seat all the way in the pivot cup. Then I stack a orange or white Khiro barrel bushing next then hanger and then a orange or white Khiro barrel bushing and cap and nut.
I am a firm believer that a skateboard truck was designed with a certain tolerance that can be exploited or tweaked a little to be safe. But if you go to extreme and the pivot is not fully seated is out of the cup by a few millimeters and the hanger is wedged up near the kingpin not in the center but near the the hanger ring.I noticed this when using a full size top cone bushing. You have changed the trucks mechanical soundness and geometry some thing will give. Luckily it only been tore up bushing and broken king pins.

Back when I first started freestyle skateboarding seriously we use to run tracker clear top bushing on top and bottom of our trucks only.We were busting king pins every hour of riding just to keeping the trucks from turning. That why I still have about 50 tracker king pins tracker gave me back in the day.
I got sick of changing kingpins plus it went against my thoughts on what skateboarding was.It was always about the turning and flowing in a surfing style. So I got rid of the hard bushings I kept putting softer and softer bushing in till I became comfortable with how the trucks performed and how they were meant to perform. I became a better skater for it and no one could ride my boards. I could do harder tricks or the same by adapting.

But I know how to solve the problem but I am not a engineer or have the financial backing.

What we really need to do is design a CNC milled out of aluminum front truck hanger. that will fit a tracker or bennett base plate like the split fire. But with LDP geometry to accept the three bushing stack and we would have a safe and almost maintenance free truck. It would probley propel faster and be more efficiently than the just trying to modifying our trucks to make it do a job it was not meant to do.
{I edited a bunch of stuff out that has nothing to with bushing talk.
Sorry I get to writing and it get long winded some times}

Besides the idea of buying a purpose-built skateboard kingpin that isn't threaded except for the end (that idea seems to have been welcomed warmly... Confused

...fear of shortboard parts maybe? Laughing

), I had another idea.

Most hardware stores sell a rubber dip meant for coating tool handles like pliers. You could tape the threaded portion of the kingpin that you need to leave exposed, and dip the kingpin.

I just bought my first Bennett, so I haven't tried this yet - but when I decide to start playing with the bushings, I think this route seems easiest and avoids stretching the bushing hole, since you can keep it as a thin coating over (but filling in) the threads.

Thats a good idea also.

How about fitting GrindKing inverted kingpins, the thread is on the bottom part of the kingpin?

I have some on some Indy 101's I'll have a look later and take some photos

Done.
Fitted Holey bushings to them.

The kingpin is inverted so that the thread is at the bottom.
The unthreaded part of the kingpin protrudes from the bottom of the Holey hourglass bottom bushing.

I must admit though that are are late 80's early 90's NOS Grindking kingpins the newer ones are shorter

Can someone throw up a picture of the bottom of a Bennett baseplate please?

How Do Alec & All Wink

Here's a link to a related topic, included are pictures from John Gallac (Samhell) of his bennett base plate with his reversed, jb welded kingpin fix type thingy, I hope this is what you are after?

http://pavedwave.myfastforum.org/about115.html&highlight=

If you need photos of un-doctered bennett's let me know, I will snap some pictures of some of mine, I have a couple with the kingpin removed also so if you need to see what that looks like?

Take care,
Barry Wink
