Vinegaroon Uniformity
TwinOaks replied to jhinaz's topic in Dyes, Antiques, Stains, Glues, Waxes, Finishes and Conditioners.
That theory does have some validity, but fails to address that the basket stamping was effected differently than the border. Typically a border is done with a camouflage tool. While it may be a little bit tighter pattern, it is anything but a uniform compression of the fibers. Also, the leather fibers are themselves much larger than the Fe(C2H3O2)2 molecules. I think the issue is not so much that the fibers are compressed to the point that the Fe(C2H3O2)2 can't penetrate, but that something, perhaps compression or slicking/burnishing, is preventing the WATER molecules from carrying the Fe(C2H3O2)2 to the tannins in the fibers. In my experiences with the 'roon, I've had leather turn brown, light gray, a beautiful shade of 'midnight blue' (I think that was some ZW leather), and a horrendous green that looked like a product of Linda Blair*.....and black of course. Reaction time varies on the acidity of the solution. In batches that still smell strongly of vinegar the reaction was nearly instantaneous - which may be a product of the penetrating ability of the carrier - and in old batches that have almost no smell, it takes up to a minute. I typically brush it on with a 1" nylon brush, but still soak it if needed. Another factor in the shading is the purity of the solution. In batches where I've strained/filtered the 'roon, I've had fewer problems. In my current batch, which is still sitting on the back porch in a 1 gal. pickle jar, getting the rust stirred up on the bottom results in some ugly patches. Speaking of rust, there's some probability that the brown is caused by solubilized (read as "itty bitty and floating in the solution") rust particles sticking to the surface of the leather. When I encounter them (yes, because I was too lazy to filter the brew), I just have to wipe the leather down with a damp rag and apply some 'clean' solution. There is a site (leatherchemists.org) that deals with the uberfun chemistry of all things leather.....but I don't go there because I didn't enjoy chemistry class beyond "hey, watch thi.......". THEY could certainly give an accurate answer if anyone wanted to delve that far into it. Note: The 'Linda Blair green' color was the result of leaving a wool dauber.....specifically the zinc coated dauber handle....sitting in a sealed jar of 'roon. I had set up a mini work area at my friend's store, and left it there for a few weeks. Being acidic, the 'roon ate part of the handle and the zinc reacted with it. If anyone is trying for a color that just screams "left in the barn to mildew"....this is the way to get it. -
Wanting Some Info On A Mitsubishi Lu2-400
TwinOaks replied to spurdude101's topic in Leather Sewing Machines
Initial google-fu searches make it look like it's a clone of a Consew 206. If you can, put a 'hold' on it until some of the sewing machine experts can chime in. If it is a clone of the 206 then it should handle the materials you listed just fine. Most of the clones have a clearance of ~1/2....maybe a little more, maybe a little less, but you should be fine sewing 1/4 inch or so of leather. Don't forget that you need to slow it down. Factory machines set up for high speed (2000+ spi) sound like " NYRRRRRRRRRRRRRRRRRR!"....and then you've sewn your hand to a strap. Please just take a word of advice on this....you do NOT want to pick even a single stitch out of your hand. -
I'm another satisfied SLC customer, but we've also had good reports from Weaver Leather, Sheridan Leather Outfitters, and several others. As far as your dyeing process....have you tried spraying yet? It's much easier to get a uniform coat at less than 'full strength', and it's also easy to get fades, so you can do 'sun burst' shading.
-
No, no idea on the website, but keep in mind that a machine that came out of a textile (clothing) factory is likely to be set up to run FAST. For leather you don't want 3000 spi. Our dealers on this site modify the machines, through ratio reduction pulleys, internal gearing, timing...etc., to slow the machines down so that they have enough torque at slow speeds to sew through leather.

You should be using a 'diamond awl', not the stitching awl. The stitching awl is the one with the spool of thread on it. I see that you're using the awl to widen the holes, and that may be part of the problem you're having with aligning holes --leather sometimes stretches 'funny', especially if you happen to be at an angle. The chisels make pretty big holes compared to an awl, so your stitching would look kind of spaced out. Here's how to use the tools you have: Glue your pieces together - that's not as easy as you might think because you need to get glue to the edge, but not ON the edge. Then, even up your edges if they aren't. You can do that with a knife or by sanding....the key is that the top and bottom pieces are in the same place. You need to make an equidistant line from the edge, both front and back. You can use the groover to do that, just don't change the setting, and your groove line will be in the same place, front and back, provided you've squared up the edge. Now, use the overstitch wheel to mark the location of each hole in the groove. Push the awl straight through the leather....as in perpendicular....and watch the back side. You'll see the back side swell just a tiny bit right before the tip comes through. If it isn't in the right spot, back the awl out a little and reposition it so that the tip comes out in the groove. If you have a surface that you can stab into, you can place the leather on that surface and push straight down. When starting, it's sometimes easier to stay straight when the leather is flat. Now that you've got a hole, run the needles through that hole. It SHOULD BE A TIGHT FIT, and you might have to use pliers to pull the needles through. If you do, pull straight, and once the needle is out, use the thread to pull it tight. Maintain the exact same stitching pattern for the length of your stitch line. If you start with the right needle, push it through and pull back (towards previous stitches) and OVER the left hand thread, then push the left hand needle through, you need to do that with every single stitch. Don't swap needle over, needle under, start on right, start on left. Each stitch needs to be made in the same manner. That will add consistency. When your stitches are done, lay the work flat and tap it down, then pick up the over stitch wheel again. Set one of the little points in one of the holes and start rolling. This flattens the stitches down into the groove and clearly delineates each stitch. If you want to see some good examples of this, look at the work by Katsass.

An artistic representation is typically highly stylized so that the viewer can identify the subject, and possibly the artist's work by that style. It wasn't until pretty recently that we, as people, had the ability to click on a picture and print it out in the comfort of our homes. Before that,....and way back before that....artists and artisans would portray an 'idyllic' version so the viewer could tell what it's supposed to be, without the onus of trying to visually replicate each and every detail of the real thing.

You can use glycerin soap (facial bar) and rub it directly on the belt after slicking. After that, it's a case of being careful and not running the burnishing cloth/wheel over on the sides.

What Size Thread For Hand Sewing 7-8 Oz Total Thickness Leather?
TwinOaks replied to LilRay's topic in Sewing Leather
138 thread at the most. f you're bonding the pieces together and just using the thread as an edge binder, you could even drop down another size. I think size 69 might be a bit thin. My earlier post had "132" which was a typo. -
I presume you're talking about a sheath to hold the axe head so the handle can rotate. I don't think you'd need ball bearings. Maybe a short bolt with a sleeve? The sleeve would be in contact with leather and could rotate around the bolt as needed. That would still allow some tension adjustment too. You could even do it with some over sized (too long) Chicago screws and 4 washers. Assemble with the leather sandwiched between sets of washers, with a CS holding all together. As long as the CS is a little longer (when fully tightened) than the whole assembly, it would have room to move. Maybe Nylon washers as the center two washers? From what I'm imagining, the axe handle needs to swivel while still hanging mostly down....it doesn't need to twirl around.

Not a criticism, but an honest question.....shouldn't the pieces overlap at the top instead of at the bottom? That way a downward stroke wouldn't catch on the armor or cut the connecting cords.

Certainly.... As we know, leather is a product of a chemical process - it is preserved from deterioration by tanning it. That process makes the leather slightly acidic on the pH scale. There are also natural oils, waxes and fats that are preserved along with the skin cells. When we drag a blade - steel, ruby, or ceramic- through leather we're necessarily also dragging it through everything else IN the leather. That's where the 'crust' comes from...though I'd lean more towards 'film' However, I think there is another possibility as well. Several people have written that they've noticed that more recently made ceramic blades have grind marks on them. It's possible that the small grind marks are picking up the same residue and "clogging" the blade, making it cut less smoothly. Stropping (as stated above) cleans out the micro grooves. Member "Shtoink" had some very insightful observations on stropping direction with the ceramic blades....I'll see if he'd like to post them here. Paul Zalesak at Leatherwrangers did some pretty extensive analysis and discovered that the chemicals in leather are actually corroding metal in steel blades. So, for steel blades, the leather actually is DULLING the edge...despite being a much softer substance. That's the reason that Paul developed his blades from a special alloy.....which, is a trade secret.

We decided that wimpy sport bikes should be regulated to vinyl and nylon. Just kidding!! I don't recall seeing anything specifically for sport bikes, so you may have found a niche market.

I thought you were suggesting making up the space with rings. That way, the original belt is the only leather used and removes the need to try and match the color. I can certainly see the merit of only using them to add new pieces. As long as the color/stamping is repeatable, then the latter will definitely be faster and easier.

Sponge is fine unless you have a lot of nooks and crannies like you find in Sheridan / Floral carving. If you do have a lot of little places to get the antique, I find that either sheepskin or fake sheepskin (pet dept. in walmart) does very well at getting the antique where it needs to go. Heck, you might be able to use a sponge on those too, but I like the wool better because it's softer.

So the trick isn't to simulate all the wear and distress......it's to get all the wear and distress...FASTER.

What Size Thread For Hand Sewing 7-8 Oz Total Thickness Leather?
TwinOaks replied to LilRay's topic in Sewing Leather
It's going to completely depend on your SPI, and what your stitching together. I'd stick to either 132 or 207 and 5 or 6 spi. -
You could do it with those plain (open / no center bar) rings...round or square...but remember to allow for the fold around each one. I'm guessing that you'd probably need 4 1" rings per side to stretch the belt 4 inches......because you'll use ~1/2" at each fold.

Hand buffing is the way to go. You could put a buffing cloth on a drill, but you have to worry about building up heat and making a burnished or burnt spot. You can buff when it's totally dry and do pretty good with whatever finish you're trying for. Or, you can spray LIGHTLY with some water and start buffing. That will likely result in a glazed finish...which is sometimes a good thing. But....you said you want a matte finish, so.... Buff when the leather is dry. Your choice of top coat / sealer will also have a major role in the finish.

The secret to edges can be found in Hidepounder's tutorial....right here in the 'How do I ....." section. You don't have to follow his way EXACTLY....but stay close to the guide and you'll have much nicer edges than edgekote will ever produce. Edgekote is a surface treatment...period. It's a product to produce a quick shiny edge, and it's basically painted on the leather. After slicking the edges, you also need to burnish, DYE them, buff them, seal, and re-buff. Since you're in hotlanta, swing by the Tandy there and check out the Professional Water Stains. They might give you some additional options on belt colors, and they're getting a pretty good review.
