Title: Adjustable collars need spacers
Post by: S12_Lifer on 05:11:59 PM / 25-Apr-16
I noticed when I set my collars on it's perch, the collars do not sit flush.  So when accelerating, you can hear "clunking" coming from the rear.   I discovered a spacer is needed to solve the problem.  I went to a local hardware store to look for a sheet of polyurethane and I ran into a "camlock gasket."  This gasket comes in different sizes so I bought two different ones (3" and 4").  The 3 inch fits perfect.  After my test drive, no more clunking!  The car handles great with this set up.  I did have to secure the rubber bumper stop to the spring with zip-ties which is the SSS 5x8 blue coil springs (300 lbs).

Your pictures are "oops-ing". I'm interested to see the setup once the photos upload properly.

Fantastic find.  Sticky?

Sticky?  Not sticky.  The 4" gasket  diameter matches perfectly to the bottom of the collar.  However, when placed on the perch, there is to much wiggle room.  The 3" gasket is a better fit around the perch so that is what I went with.

No.  I meant possibly sticky the tread.  This is the type of simple fix that I'm sure many of us have wanted for years, thus possibly sticky at the top worthy.  Also it may prove difficult to search for in the future because there are so many possible key words to try.

Also, that is an awesome shop/work space in the background of some of those pictures.  I'm not sure if you do your own welding there but that can of Brakleen sitting out prominently prompts me to remind everyone to ALWAYS make sure 100% of it is rinsed off before welding parts you used Brakleen on.  When heated to welding torch temperatures a small drop of that stuff puffs into a cloud.  Anybody who catches a whiff of that cloud will have life long nerve damage if they survive it.  Seriously life altering nasty shit.  Don't get me wrong, I use Brakleen all the time because it is awesome.  Just avoid it on parts to be welded if you can, then clean thoroughly and let parts sit overnight to evaporate anything that was missed if you do.

Yep, phosgene gas is gets produced and it's very nasty stuff.

Nice find on the collar gasket.

Thanks iceageg for reminding all of us about the safety issues when using Brakleen.  I personally do not do any welding at this shop.  I leave that to the professionals.

thanks, I have the BC set, but will keep a eye out and maybe put the ring in just to be on the safe side so I don't have to take it apart again

Thanks iceageg for reminding all of us about the safety issues when using Brakleen.  I personally do not do any welding at this shop.  I leave that to the professionals.

The guy who does most of the welding on our aircraft parts almost lost a friend (also a career welder) to a Brakleen accident.  His wife found him on the floor in his workshop and called 911.  They believe there was a drop of fluid that was captured/retained in a small rusty patch adjacent to where he had ground down the surface for welding.  He now has limited fine motor function and chronic constant pain.  He will likely never be able to work or live alone again.  So it has become my #1 warning to new and self trained welders.  I no longer use Brakleen on parts we send to our welder.

On a happier note . . . sticky for the simple win that our lifer has found???
