Is there an attachement for CB4500 for finishing leather edges?

Well that Cobra burnisher is again 450$ and it has similar RPM as my common DeWalt grinder, which is 3450 RPM.

I would Need just an propper burnisher wheel which fits to the grinder.

As well I figured the clogged with leather sanding Stone will act as a burnisher the more it is clogged. Somehow that works to a certain Point.

What else is "burnishing" than hardening the leather by applying friction heat coaling it (hence burning = burnisher) partially.

Best is to find some method of burnish effectively (btw beeswax is not availlable over here nor does saddle soap).

If you prefer to discuss burnishing techniques instead of machine edge binding, there is a better section of our forum where you will get better answers. The forum is titled: How Do I Do That

I encourage you to start a new topic in that forum as this one is for leather sewing machines.

I just did another Experiment according to the Video by turning the grinder on and Holding an simple bathing Soap which contain glicerine, at it so it's clogged with bathing Soap. I ran the Holsters edge through it and afterwards moisturizing the edge with water. This makes the edge shiny and sealed.

That seals the edge but IMHO does not look so nice as the "ply Wood" look of the Vaseline Version. I can get here Petroleum Jelly as well for slicking. Dunno if that improves the burnishing.

Read this article about burnishing edges, then look at his hand and machine mountable burnishers.

You need to be careful using the grinder like that.  If whatever you're clogging the wheel with has a different rate of expansion than the actual stone of the wheel, you stand a decent chance of fracturing the wheel and having it let go all over the shop.  You need to buy some canvas wheels that are specifically made for doing this.  Or leather wheels.  You're gonna hurt yourself.

I use a bench grinder as the motor for burnishing, but I use a wooden burnishing wheel from Nigel Armitage. It's nothing particularly fancy but well made and well balanced for minimal vibration. Almost any hardwood will work for such a wheel, or as others have said stiff canvas or felt, leather, plastic... they key is that it's smooth, firm, well balanced for and not going to fracture. 3000 RPM is bloody fast -- for a 50mm wheel that's about 57KPH. Alex is right -- fracture a 125mm wheel like you're using and you'll be dodging bits of rock at 140KPH. Make a hell of a mess of you.

Different leathers burnish better with different substances and techniques. I tend to use diluted water-based glues as burnishing agents as this gives a faster and longer-lasting result. PVA (white wood glue) is a good starting point. You can use just about any wax for an extra shine.

Hi,

I have this availlable for burnishing edges. An 3450 RPM DeWalt bench grinder with 2 sizes of sanding Stones (one fine and one medium coarse).

In the fotos it Shows 4 layers sewn together 5 oz cow leather using Vaseline as slicker Agent (the item is an pocket Holster + mag pouch for any mouse 380 ACP pistol). The fine sanding Stone was used and so it has clogged the outer Surface with leather material from "burnishing" leather as such as it's now not sanding anymore but rather it's a Slick Surface.

What do you think?

How can I use an bench grinder for leather burnishing? Any more ideas?

Any experience using an common bench grinder as an burnisher?

Burnishing edges is really nothing more than "slicking" and polishing the leather to a smooth and glossy surface. The method that I found most effective and time efficient was using a 1" diameter hard felt polishing bob mounted in a bench-top drill press. After dressing the edges with a drum sander, then beveling the edges, I would dye the edges, then rub the edges with a 50-50 mixture of beeswax and paraffin wax, then polish the edges using the hard felt polishing bob turning at about 1700RPM. The friction caused the wax to melt and moderate pressure forces the wax into the exposed leather, sealing the edge quite well. A minute or two per item (belts, holsters, etc) left the edges at a highly polished state.

I have finished holsters and belts that I have used for more than ten years and the edges still look great. When a bit of wear shows I can apply a little bit of dye, rub the edges with the wax mixture, and polish out on the felt bob, leaving the edge looking like brand new.

Friction causes heat and abrasion, and the felt polishing bob uses both to quickly finish the edges to perfection.

Years ago I became obsessed with creating the perfect edge. I used custom hardwood mandrels, working edges for endless lengths of time trying to achieve perfection. After trying the hard felt polishing wheels and the wax mixture I realized just how much time I had wasted year after year, when the desired effect can be had in only a few minutes.

I have merged the entire previous discussion into this one. It will serve as background for new visitors to the topic.

I had today switched to an aluminum fan belt wheel type for burnishing.

At first it seemed promising but then I went back to the original bench grinder set up as that came from factory (one coarse and one middle sanding Stone).

The sanding Stones give me a bit better shinier and even finish than the belt wheel.
