Test Shell of Crappy All White Oiter TF

[cmjlab]

I figured I'd share a test I did to see if I could find some use for the rolls of crappy TF with all white outer wrap.  It burns at around 3.5 to 4 seconds per inch, has a tiny B.P. core, and is overall quite horrible to work with. Because of its slow burn time, I had to work with super tiny pieces of TF and I Def won't do it again!  I also struggled with timing and a couple inserts that didn't ignite (which is not acceptable for my uses).  Anyways, without further ado....

So noone else has tried the TF I'm referring to? Or am I the only one with crappy results?  I'll try to get a photo of it up today so people can see which time fuse I'm referring to.

I bought about 50 ft of time fuse a couple of years back, so I haven't been in the market for some for a while. So, if you take a picture of it, I would appreciate it, so I know what to avoid.

Fuse on left is the crappy wgite / tan time fuse, stuff on right is the better Chinese TF.  Notice tge difference in the core size, and behavior when cut.  Chinese TF keeeps it shape, white TF squishes and powder falls out.

This is the white / tan TF vs. Chinese TF

The biggest issue isn't necessarily the small spit of flame when it burns through, nor the fact that it burns so slow.  Biggest issue is that you can't effectively punch / cross match it because the core is so small, and you can't slice it to tie match in since the core is flimsy and timing sucks if you're trying for tight timings on a "timed report shell", and the core is so small that it doesn't catch flame very easily either, resulting in blind inserts (and the work of trying to pick them up later so a kid doesn't find them and hurt themselves).

I think that's the stuff that I ran like hell from when I read the reviews on pyrobuild and went and bought some of the stuff with two red / 3 white thread patterning instead.  Onlinefireworks where I grabbed that had some grey stuff for cheaper as well and I was suspicious that it was the same thing so I avoided it.  I think pyrobuild is selling it off for $1 a foot at this point but it sounded like theirs might have even more problems than yours since people reported blow-throughs of the core and they state that it can ignite from the sides.  I'm not sure how it's at all useful given all that but I'm sure somebody is willing to go through 20 hours of labor fixing it to avoid the extra $$

Yeah this stuff isn't 'THAT' bad I guess, other than the terribly slow burn, the small flimsy core, it otherwise performs as time fuse.  

I was able to get 'ok' timing on the shell in the video above.  It would probably work okay as the main timing element on ball shells if you used 2 fuses like seen on commercial ball shells.  

Idk.  I Have a bunch, it'll probably just sit around and gather dust till I run out of good TF, and then I'll probably try it again..... the cycle of bad memory!
