[Ansteorra-missile] Type of Siloflex APD

Sat Oct 8 20:59:04 PDT 2005

Did you check at the black pipe section.  For some reason they seem to always put it with the steel pipe.  If not that would be really strange.  They normally carry the 160 psi in 1/2", 3/4" and 1".  Oh and I hope that was supposed to be 5/16", if not I would hate to get hit by those buggers.  Talk about knocking on your front door.  If you still are having problems finding some let me know privately and I can send you a dozen or so in the mail for testing.

  I check at both Home Depot and Lowes here in Dallas and they both 
  carry only 100 ft coils of siloflex and that is either 100 PSI or 160 PSI,
  but in the wrong diameters. No straight sections available, would 
  have to go on line to get a order of straight siloflex.

  I already have miter box and saw, this is how I cut the GT APD's,
  that I am currently using. 

  I got another response on the SCA Missile list from Siegfried, 
  concerning 100 and 160 PSI siloflex. He did not see much 
  difference between the two in weight, but he is using 15/16" shafts, 
  as his shafts weigh more than the APD. 

  This is what Siegfried wrote back:
  Routed is easiest to build, if you happen to have a router table setup, and
  make a few jigs, then it's really easy. Ignore the External Tab, it's not
  used by anyone I know right now, for the primary reason that it wastes
  siloflex. Even the 'creator' of that style, last I heard, wasn't using it.

  Internal Tab is the easiest to build with less technology. Just need
  something, anything, to cut slots with (dremel, handsaw, tablesaw, etc).

  As far as straight/angle cut ... I'm now of the opinion that it doesn't
  really matter for performance/etc. Though the angle cut is nicer when
  hitting something, and less lightly to get torqued off.

  Ok, I have until December 31st to make my final decision on the 
  which APD to go with.

  Thanks for the information.

    Been using 160 psi for Crossbow bolts.  The heavier weights seem to balance them out better.  For a bow I think I would go with the 100 psi.  It would give you a weight closer to what you are used to using.  The 160 you can get in 5' sections already straightened at Lowes, Home Depot.  I believe and I could be wrong that they sell the 100 in coils only.  If you can find someone to supply it straightened and the price is right (Remember to figure in your time to straighten) go for it.  If you have time but not the money buy the coils and straighten them yourself.  I would most likely go with the internal tab if you don't have a router table or the use of one.  A simple miter box and saw can be bought for a relative small price.  Of spend the money and buy the Asgard APDs.

      Thanks Iaen for the input. This is what I thought from reviewing the photos on Tessa's web site. 

      Yes, I noticed how similar the GT APD's was to the vanes I had on prior to switching to GT APD's.

      Which type of Siloflex are you using?

      100 PSI

      or

      160 PSI

      Also, are you using a recurve or crossbow or both? Sorry could not remember what you were using.

      Are you buying the straight siloflex locally or having to send off for it?

      I have the dremel tool, no router or table saw.

Hmm, lets see.  Having worked with several designs here is my input.

External Tab:
Most difficult to make as the tabs have to cut after cutting to length
needed.  The angle cuts can be a bit of pain as you are switching back and
forth with your saw.  More to difficult to round over edges properly.
Fairly easy to attach.

Internal Tab:
Easier to cut but still have to deal with the angles.  Have to cut the tabs
in afterwards.  The most difficult to attach having to hold the thing and
wrap the tape at the same time.  Still difficult to round over the edges but
easier than the external type .

Straight with routed channel:
Easiest to cut, 2 90 degree cuts and done.  Best way to make routed channel
is a jig and a table router.  You can do 5' lengths real easy if you set it
up right.  I do mine before I cut them and do them in large enough pieces to
handle easily.  Rounding edges really easy if you have a dremel tool and
1/8th router bit.  Attaching can be done easily, run a bead of hot melt glue
down the channel and stick it to the shaft.  Set it aside and do the next of
a bunch.  Tape them all at one time.  Kinda assembly line like.  Also uses
the least amount of material.

Flight:  I have not noticed much of a difference in any of the styles.  They
all work as a ringfoil in flight.  Actually they seem to fly as good if not
better than fletches.

After reviewing Tessa's web site:

http://www.combat-archery.com.

concerning the 3 different types of Siloflex APD's - External Tab,
Internal Tab and Routed Channel. Would like to know the advantages and
disadvantages of each type of design in the following areas:

Ease of building -
  1. Angle cut on front and straight cut on back
   2 Straight cut on both ends
Attaching to the shaft -
Flight
