Edge Heat Burnishing?

[DavidL]

Recently I have tried to do some heat edge burnishing w/ a soldering iron that gets really hot. I first sand and then apply the soldering iron. Is the edge paint (acrylic?) the missing piece to give the edge a smooth plastic feel.

Im asking because without the edge paint Id think it would be completely smooth (but not plastic feeling) but is a bit uneven and the two pieces aren't merged seamlessly . Is this what is expected without edge paint and will the edge paint fix the unevenness and blend in smoothly?

Never heard of such a thing, . . . but then again, . . . only been messing with leather for some 40 years.

May God bless,

Interesting. Do you simply touch the hot iron to the dry leather? Is there a "painting" stroke involved? I can't imaging getting a glass smooth edge burnish with a soldering iron.

I believe I have read somewhere that a device was used to edge a piece of leather but it was ran through the device in a controlled manner to ensure a smooth surface.

"Is the edge paint (acrylic?) the missing piece to give the edge a smooth plastic feel?"

In my experience, no.

" .......two pieces aren't merged seamlessly."

How about telling us what you are making and, maybe, showing us an example. Difficult to address the questions without some more information.

If I haven't seen it done before I would say the same thing, it seems impossible. But heres a video of a worker making a bag w/ a expensive heat tool.

Im not too sure if the edge paint is acrylic or dye or some other thing entirely and how it will hold up w/ the iron and how to produce that smooth edge.

Also the problem may lie in the fact that I wasn't as aggressive with the sanding because I believe the rough bits from sanding will not help get a smooth finish.

My steps for the next piece.

glue pieces together

compress tightly

sand with high grit paper

use regular dye on edges

use a soldering iron on the edges in a stroke movement

touch up dye

add paraffin or beeswax and go over with the iron.

Anyone had success or see anything missing or wrong about the steps?

I too have been trying to emulate the results you get from the French tool, the Fileteuse Manuelle.

Not quite sure what they use with the Fileteuse but I think there may be some wax or a combination of wax/paint involved.

For me the soldering iron gets too hot. With a temperature control it may work quite well; especially for creasing.

I tried melting Angelus edge paint; doesn't work.

Today I purchased Fenice edge paint (Tandy Pro Edge Paint) and I'm very happy with the results so far. I applied it with a dauber with the dauber cut off. No sanding or melting needed. Sanding may be needed on other projects.

There's an entire thread devoted to the tool.

So far the only edge paints I've read about that come close to Hermes is: Fenice, Stahl and Beraud.

Thanks il give it a look.

"..Not quite sure what they use with the Fileteuse but I think there may be some wax or a combination of wax/paint involved..."

Regarding the "wax/paint" thing.. after reading this thread (and another thread on the same subject) I still think that there must be a wax/paint mixture or a colored wax that can be used. In the other thread, our forum member Art (who's usually a really good source for information) mentioned that the product used was 'Yankee Wax'. His comment got completely glossed over and know one else mentioned yankee wax again. FYI, it's been used in the shoe making craft for years and years and looking at it, it seems to be just the ticket when used with a Fileteuse of some sort. Art suggested a basic "iron" heated with a flame like the shoe makers use it - but this thread is about the electric fileteuse and soldering irons. I think it might be worth a try (but I don't have my Fileteuse yet). Thoughts? Here's a look at this colored wax:

I've come across & read about the Yankee wax too. I'm pretty happy with my edges right now with the Fenice edge paint, sanding and a coat of paraffin wax and burnishing. I still need to try melting it on some scraps.

When the time comes to step up it will be the fileteuse and Beraud edge paint. I think it has the wax in it.

I've been trying this technique out lately. In general I prefer Veg Tan leather and traditional burnishing but I've been trying to make some watch straps using alligator skin and traditional burnishing just doesn't work on that type of stuff. I have some Italian edge paint from Cambell Randall as well as some edge paint from Tandy. They are pretty similar stuff. I believe that this type of paint is latex based.

So far, what I've been doing is putting on a somewhat heavy layer of paint, letting it dry completely, then using an iron on it. The Iron I have is the one that Campbell Randall makes. I set it so it's about 160-180 degrees farenheit (I use an infrared thremometer to check). What I notice is that the iron kinda melts and smooths out the paint a little bit. Too much heat and it seems to melt the paint right off so that's not good. After I use the heater, I sand with high grit sand paper (320-400 grit). It actually seems to sand off quite a bit of the paint as well but it smooths it out even more. I repeat this process one or two more times until I get an edge that I feel is smooth. Then I sand that down and I apply a final color using regular leather dye over the painted edge. Then I finish with paraffin wax on a felt wheel.

The results so far is decent. I wouldn't say they were great. The fact is that every time I put a new layer of paint on, it doesn't go on completely smoothly. When I use the heating tool, it smooths out the paint but not in a uniform way. To be honest, I don't completely understand the purpose of using the heating tool. Maybe I'm doing it wrong but I don't get as nice and uniform an edge as I can get with traditional burnishing. The edge is pretty decent though but not perfect.

Anyways, if anyone has mastered this tool, please share.
