Hello all,
Here is a summary of the responses I received regarding carbon socket
trimlines. Thanks to all of you who responded. The number of responses was
quite impressions.
Ready made products…
1. The most common responses was to use EZ Trim from Mica Corp. The
product is pliable and adheres to the socket. I purchased a roll of this
and have used it on two sockets so far. Use a heat gun to heat the adhesive
and make the trim pliable. Make sure to put pressure on the trim until it
cools to ensure a good bond. Mica Corp 800.690.6422
2. ShearBan has been successful for some folks. Attaching it to the liner
or the socket is possible. Unsure of longevity. I received a sample of the
ShearBan and am anxious to try it.
3. Car trim was also suggested.
Some fabrication tips suggested…
1. Put a layer or two of felt into the lamination at the trimline to build
a thicker/softer edge. Pigment is recommended to keep the cosmetics
professional. – RS Marchisio RTP
2. When the socket edge has a greater radius the issue is resolved. Also,
during the layup adding extra layers of nylon stockinette between the carbon
fibers at the proximal end. -Dave Janke CPO
3. “I do not do a 100% carbon layup, I use some nyglass and felt and cut my
carbon short of the trimlines by about an inch. I also use pigment in all
sockets. I put an extra layer of felt at the trim lines to be able to bevel
a nice transition and cut down on edge pressure. Started this a few years
back. No problems with carbon anymore.” -Win Gasperson, CPO
4. Paint the edge with Siegelhartz. Maybe a few coats to really cover all
the fibers. You’ll want to make sure that the amount of catalyst used does
not create a “hot-mix” effect or the Siegelhartz tends to crack or bubble,
which could defeat the purpose by creating a sharp surface. -Jonas
5. Using a thin Vivak inner socket is nice and allows you to do away with
the PVA bag. The plastic seems to interact with the liner a little better
than straight carbon. -Brent Wright
