silk backing, cutting clean edges
« on: March 13, 2012, 03:43:41 pm »
How do you get the edges neat and clean? I've done a couple and I cant get the cut lines perfect and straight and i always have little threads popping out, or little divots of silk that dont go all the way to the side or come over slightly

I will say that first, it helps to make sure you put a layer of glue on top of the linen (or silk) after it drys the first time. After it is dry, I cut the extra off with a razor blade. Next, I use some sandpaper and sand the edges a bit until they are even, this will take care of the little threads sticking out.

A fine metal file will also work to dress up the edges.

Yes. Just like snake skin, rawhide and sinew. Once its dried you can lightly clean up the edges with a sanding block and 120 grit.

Thanks guys, my wife helped me glue the silk down and she wanted to trim it, but she is a perfectionist and was going nuts trying to get it perfectly straight... I will put a light coat of glue over the silk tonight and clean up the edges tomorrow.

If you don't mind me asking on your thread jermcramp,  once the top layer of glue dries on the silk or snakeskin is it possible or wise to put a couple of coats of poly to seal the bow and the edges that were sanded?  Also before applying the prefered snakeskin or silk backing can you put teak oil (or prefered wood oil,) on the entire bow, including the back, and not have to worry about the glue adhering to the bow's back?  (jermcramp hopefully you are ok with me asking this on your post, I had no intention of stealing it from you just had a couple related questions to this process since I plan on doing this very soon on a bow of my own.)

I put a little glue on the edges of the silk after I sand just to make sure everything is glued down and smooth.

Survivecrunch, I always apply the poly after I silk or snakeskin back. That is how I make it waterproof. Just make sure you give it plenty of time for the glue to to dry so you don't seal the moisture in.

Dont spread glue over skins or rawhide however.

Well, I was just saying, that I usually add another coat of glue on top of the fabric after it is dry, as most of the glue will be soaked into the fabric when dry. And it could be easy to bump the fabric and rip it. I guess you don't have to do this, but it has worked for me. It does make it slightly easier to sand as the fabric is coated entirely in glue so the little threads won't pop out as much and can be sanded away. Some people might not wanna do this though, as I have seen some people glue on silk backings with like camo colors or designs that they wanted to show on the back of the completed bow, but if you coat the entire backing in glue the color would just be yellow from the glue? Just wantin to clarify.  :)

There's info on my site.  I cut the silk with a razor blade after installation. I sand the edges lightly and reglue the whole backing. Jawge

I've only ever used white linen so I really wouldn't know. Always wanted to try a gordon-ish colored silk backing though.
