canonitr Report post Posted September 23, 2021 Hi, i'm not sure what's the term for it, so i am just going to use "leather fiber" for now.. basically, when i am about to finish my leather edges, i notice that for most parts, i am able to get the 2 or more layers sandwiched nicely (sanded nice and even).. however, i do get small portions of the edge, that just seem to not be able to be flattened down nicely, and looks like the leather fiber at that part is is uncompressed or loose. any glue or tape at that area is still there, between the 2 pieces of leather, but the fiber just behind the adhesive just loosens up. it happen whether i use contact glue, or double sided tissue tape.. it happens rarely between 2 vegtan pieces, but fairly often if one piece is goat or some other leather (in my current case, its nubuck). the nicer parts can get burnished with edge wax. bees wax or paraffin wax, or more recently with the Crimson OEM fileteuse, but that loose fiber is giving me some headache.. i'll try to get a picture of what i mean later on tonight (my time) Quote Share this post Link to post Share on other sites
Klara Report post Posted September 23, 2021 Have you tried progressively finer sandpaper to get the loose fiber off? My shop says to rub only in one direction... And then Tokonole or similar to glue the fibres together and lots of elbow grease for polishing. Quote Share this post Link to post Share on other sites
canonitr Report post Posted September 23, 2021 i have already sanded it, but its not actually fiber sticking out, but more of a loose edge..i have tried tokonole (similar) on other projects, and it doesnt really work, though i never actually compressed it after application..

canonitr Report post Posted September 23, 2021 a picture i got from the internet.. the lower piece has loose fiber ,,, source https://www.leather-dictionary.com/index.php/Looseness Quote Share this post Link to post Share on other sites
PastorBob Report post Posted September 23, 2021 sciving it may help, before sanding. Still not sure where the fibers are if not on the edge. Quote Share this post Link to post Share on other sites
Tugadude Report post Posted September 23, 2021 If your edges are as rough as shown in the photo there is something wrong. That won't happen if you use gum trag or Tokonole. Quote Share this post Link to post Share on other sites

If you just paint on the Tokonole it won't do anything, it's the rubbing that's important. Quote Share this post Link to post Share on other sites
fredk Report post Posted September 23, 2021 I've been following this and thinking about it. The only time I had leather like the example was a piece of chrome-tan upholstery leather. I still have some of it. The only way I got around the 'loose fibres' was, after cutting nearly to size I liberally applied some contact glue and rubbed it in. Then after gluing to the other pieces and/or after sewing I cut down to size, thus cutting through the glued down fibres Quote Share this post Link to post Share on other sites

Though it seems it’s not the type of tanning that is the root cause.. Quote Share this post Link to post Share on other sites
Danne Report post Posted September 23, 2021 I have a couple of questions. How does the flesh side of your leather look? is it very "furry"? How do you apply contact cement? a thin layer on both pieces and let it dry until tacky? If you don't flush cut your edge and sand it, do you instantly start to sand after glue? and what direction do you sand along the edge or across the edge? Do you hammer down or press the edges after gluing together? Quote Share this post Link to post Share on other sites

But if your edge resembles that, which is why you posted it, then there is something wrong. Like I said. Quote Share this post Link to post Share on other sites

RockyAussie Report post Posted September 26, 2021 The only way I would be doing this would be by using an edge paint. You let the first coat or 2 soak in and fill all the voids and then start sanding or sometimes using an iron to smooth out the roughness before applying some further coats. Some people use PVA wood glue as well but I think that would depend on the end use application taking into account the amount of flexing it needs to withstand and so on.

I couldn’t find the pieces that I had .. but what I did do was get base coat and edge paint Quote Share this post Link to post Share on other sites
canonitr Report post Posted October 4, 2021 I got Ledafil Super as base coat , and orly bt extramat as edge paint, though I am actually using wuta for the above .. I also have some basco edge coat in clear (https://www.goodsjapan.com/basco-leathercraft-edge-coat-brown-leather-edge-dye-dressing-kote-finish/a-20161) and wonder if I could use it as base for painting as well.. seems to dry to the same as the ledafil Quote Share this post Link to post Share on other sites
