twolane, great work and love that red powder.

just a recommendation, but i would devise a tool (maybe a bent wire) that i could use to pull up on the release if it ever stuck in the open position (as they WILL do). and carry that tool in your bag.

great mod!! you got your hole drilled yet henry?????????????????/

Nope.  Sold 'em.  Decided I like the look of the C/Rs.  Besides, I'd burn my fingers tryin' to mash 'em since they're so far down in the bridge holes.

And they came to motorcycles from other applications where immediate reliability every time wasn't a great concern anyway. 


We have them in all of our chainsaws and power saws, have to use them to start.
The units get started everyday, 365 days a year and we haven't had a failure yet.

Wonder why they can't make them as reliable for bikes.

Not really hearsay but something I consider a fact based on who told me.

I owe apologies to someone.  Trouble is I forget who.  The subject of bridges and compression releases came up two or three months ago.  Someone saw the thread two or three weeks ago and ask for imagery.  I promised it for the near future but have forgotten who requested it. 

To whomever I owe the pics; here you go.  Sorry for forgetting who wanted these.

Don,
this is great piece of work, had to take of my bridge covers for CR placement after cyclerama head work. Did you center the bit on the second wing or the top plate? also did you have to bevel or perpendicular to surface? thanks john

John,
The pilot hole was in the beveled (angled) part.  I simply extended the pilot bit a lot from the hole saw.  Drilled in to the angle straight on to it then backed out a bit.  Rounded out the pilot hole just a bit then brought the hole saw down perpendicular to the flat surface on top.  It was taking it out in steps but a sharp saw and only moderate RPMs made it really a very simple little chore.  Dressed the edges when done with a Dremel and you'd never know they weren't made this way to begin with.

Henry, went out earlier this evening and did my very best trying to convince a particular lass to let me prove that very point (or at least make a valiant effort of it!).  Alas, she spurned me.  So I came home and worked on the bike for a couple hours or so.  She loves me :2vrolijk_21: .

thanks Don,
I guess I will boldly go where only 2lane has gone before ( even if I screw them up , they were just sitting in a box anyway!) john

And they're (relatively) cheap by Harley standards.  It'll be an adventure :2vrolijk_21: .


Since this first came up one of our brethren mailed me his to mess with.  I can understand that buying a set of decent hole saws is more expense than the project is probably worth. 

I drilled out that 2nd set and the material worked as it did the first time.  Was a little concerned that a fin might break off or something if the saw hung up.  But nothing happened either time.  So it might just be a fairly repeatable process.

Well Don, we can't be good at "everything."   ;D
The sled will always be there for the rider.  Problem is, she don't care who's riding, and will happily take a poundin' from anyone.  Wonder does that make her a Sierra Lima Uniform Tango?

Henry, it just might.  But we'll never judge.  Certainly don't want to piss them off either.  A cranky bike is a bad thing ??? .

yep, she may just pull to the side of the road with arms crossed. every time you push her button she will respond with a b^tchin sound. talk sweet, rub all the right places and when she is damn good and ready---------------she may start to purr again.

Too true.  A bike with an attitude and a mind of it's own might lift your spirits only to break your heart again around the next turn.  She's a mean animal best to be avoided.  Keep her happy.
