The Global FlyFisher has recently been updated to a new publishing system, and there may be a few glitches while the last bits get fixed. If you meet anything that doesn't work, please let me know.

Light Cured Acrylics and Bench Lights...

The forums are very quiet

The Global FlyFisher forum has existed for almost as long as the site, and the oldest posts are more than 20 years old. Forums aren't what they used to be. Social media has taken over a lot of their roles, and the GFF form is very quiet ... to put it mildly.
We keep everything online for the sake of history, and preserve the posts for as long as possible, but as you will see, quite a few of them aren't in a good shape, but rely on old images hosted elsewhere, which are no longer available, odd codes from old systems and much more, which can't be shown in a decent way.
But the posts are here, and you can - if you insist - start new threads. But don't stay awake waiting for replies, because they are unfortunately few and far apart.

Fly tying - Tie Better

[b:c9f7c6b081]Curious Unintended Consequences...
I like noteworthy tools of quality that work... if they look good too, all the better...
IMHO: Marc Petitjean's stuff is Leonardo Da Vinci [i:c9f7c6b081]BRILLIANT[/i:c9f7c6b081]...
His Swiss Vise is amazing... the 3W cool L.E.D. is an exceptional tool accessory...
[img:c9f7c6b081]http://i198.photobucket.com/albums/aa176/Phracas/PB201711.jpg[/img:c9f7…]
FYI...
Whilst tyin' at the Symposium I had the opportunity to use this beautifully designed light and was dabbling with some Light Cured Acrylic...
The properties of the light allowed for good colour rendition, attention to detail, and was easy on my tying eyez... NICE!!!
But it soon became apparent that a premature skin was developing on my target... 'almost like epoxy approaching initial set...
Interesting...
After returning home to my bunker here at Area61 I conducted an "unscientific" experiment...
I placed some CCG, Tuffleye, FLEX, and Bug-Bond on a glass slide and exposed the samples to my DayLight florescent tying light...
an uneventful starting off point...  
[img:c9f7c6b081]http://i198.photobucket.com/albums/aa176/Phracas/IMG_0349.jpg[/img:c9f7…]
5 minutes under my DayLight lamp...
'bodkin pokes and strokes healed quickly...
[img:c9f7c6b081]http://i198.photobucket.com/albums/aa176/Phracas/IMG_0350.jpg[/img:c9f7…]
the same samples with 4 minutes of exposure to the cool L.E.D.
my bodkin strokes across the surface revealed slight memory...
[i:c9f7c6b081]'skin[/i:c9f7c6b081] had begun to form on ALL the acrylic samples...
[img:c9f7c6b081]http://i198.photobucket.com/albums/aa176/Phracas/IMG_0351-1.jpg[/img:c9…]
after 6 minutes under the cool L.E.D.
the partially cured acrylic samples had become somewhat firm and unworkable... the strokes were now quite tenacious...

The [i:c9f7c6b081]"Moral"[/i:c9f7c6b081] of my exercise...
I like light cured ACRYLICS and I like the cool L.E.D. light but...
If you are going to be using "light cured acrylics", consider your proximity to UV and Blue Light sources [windows] to include your source of bench light...
Evidently, the cool L.E.D.'s have some of the specific "excitation frequencies" that can start the acrylic curing process...
Would I buy/use this light... ABSOLUTELY!
but I wouldn't use it while casually applying light cured acrylics...
'a proper sense of urgency might resolve the unintended consequences...
Go phigure...
Who would'a thunk?!

'several hours in the sun reveals some grungy porch windows and the cured samples...
left to right...
CCG flexible / Tuffleye Core / Tuffley FLEX / Bug-Bond Original

#1 is a bit frosted but translucent / the other three are gin clear...

Pete,

Funny with Petijean's vice. I always found it overly complex and way "too flexible". Jack of many trades, king of none, you know. And very expensive too. But is sure is impressive when Marc demonstrates it.

Fun experiment with the light curing glues. I have used Bug Bond and love it, but have no experience with the other brands.

PS: your windows looks like mine! ;-)

Since you got this far …


The GFF money box

… I have a small favor to ask.

Long story short

Support the Global FlyFisher through several different channels, including PayPal.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
