Members Zac Posted October 29, 2020 Members Report Posted October 29, 2020 Hi Everyone, I mostly make wallets but have been making the tote and backpack. I almost exclusively use veg tanned Kangaroo leather, it's a great leather and I find it gives me a bit of a point of difference to stuff from outside of Australia. For making straps I cut by hand strips (I find the leather is too thin for a strap cutter or am I just bad at using a strap cutter?), then glue, sew, sand the edges, bevel, and then burnish. The whole process is really time consuming so I was wondering if there is anyone out there that has found the best method? I use a sewing machine but everything else is done by hand, preferably I would avoid buying a heap of tools! Cheers, for any help! Quote
Contributing Member fredk Posted October 29, 2020 Contributing Member Report Posted October 29, 2020 1. You must be using really thin leather. I can cut as thin as 1mm with my strap cutter 2. plan ahead. cut a wide piece of leather, enough for several straps. turn this over and glue to the main hide. then use a strap cutter to cut the double thickness in strap widths as needed. using a fresh sharp blade you'll get a nice clean cut edge which won't need any sanding Quote Al speling misteaks aer all mi own werk..
Members Matt S Posted October 29, 2020 Members Report Posted October 29, 2020 Not all strap cutters are created equal, and the specific blades for them, I find, are absolute dog toffee. The typical cheap Chinese made cutters (including Ivan) tend to be hit-or-miss, whereas the one I got from Leather Works Prod Co is perfect. Far better blades are the ones designed for injector style razors. Thinner, sharper, last longer and are physically longer, which lets me slip a blade downwards a few mm when it blunts, exposing fresh edge each time. Of course you also need to adjust your cutter correctly to get good results. Ideally, adjust the daylight between the two bars to just smoothly pass the thickness of leather. Technique is simple -- pull the end of the strap slightly away from the rest of the hide, but not enough to bind or catch. I am fairly well practiced with a well set up cutter and can reliably cut straps no more than 0.5mm difference when glued together, which I think means +-0.25mm tolerance per strap. That's with 2mm medium temper chrome cowhide, FWIW. Of course the really efficient way to cut matching straps is cutting by die, or with a mechanical strap cutting machine. Maybe a laser, but then you get scorched edges and a long cycle time to deal with. Quote
Members Zac Posted October 30, 2020 Author Members Report Posted October 30, 2020 Thanks guys, I will try glueing together before using the strap cutter. The kangaroo leather is around 1mm thick and it’s probably a case of poor user and maybe a dodgy eBay cutter. More practice should help! But either way glueing first should save a lot of time. Thanks again! Quote
Members Handstitched Posted October 31, 2020 Members Report Posted October 31, 2020 @Zac G'day from west Oz I too use roo hide for wallets etc., best leather for wallets imo , but I also use roo hide for making or repairing hand bag handles etc. I haven't had much luck cutting thin leathers with a strap cutter either. To cut those, I simply use a metre ruler ( or 1/2 mtr) pressing down as hard as I can , and my knife is super sharp . You could also use a sharp rotary cutter, which is probably best...I just never got around to getting one myself ...old habits HS Quote ' I have a very gweat friend in Wome called Biggus Dickus, He has a wife you know, do you know whats she's called?

Members Rahere Posted October 31, 2020 Members Report Posted October 31, 2020 For the edge burnishing, use a dremel with a spindle-mounted head (I got mine from Proops, a man-toy shop originally on London's Tottenham Court Road, now on Etsy). Far faster Quote
Contributing Member fredk Posted October 31, 2020 Contributing Member Report Posted October 31, 2020 Proops sells through ebay as well. Though I'd hardly describe what they sell are 'man-toys' ~ they sell tools, tools for making things https://www.ebay.co.uk/sch/Business-Office-Industrial/12576/m.html?ssPageName=STRK%3AMEFSXS%3AMESOI&_ssn=spoorp&_sop=15 I second the use of a rotary blade knife. Invest in a 60mm diameter blade one by Fiskars or Olfa. Not only are their blades superior but the knives themselves are more ergonomic. Plus, I've found, the best of these knives slide the blade down to the working position, from its safe position. The 28mm and 45mm knife blades don't clear the handle by more than about 1mm, not enough to cut through 1mm leather. The 60mm comes down further. Quote Al speling misteaks aer all mi own werk..

Agree with the rotary blade for cutting straps but I'm not quite clear on what you mean, Fred. I have/use both 45mm Fiskars and Olfa rotary cutters and the blade stays in the same place on the handle. It's the guards that move up and out of the way. There's at least 8mm of clearance between the blade edge and the handle on the Fiskars and I can cut 12 oz (4.8mm) veg tan without any problem. Of the two, I find the Fiskars to be more ergonomic for me. Regards, Arturo Quote
Contributing Member fredk Posted October 31, 2020 Contributing Member Report Posted October 31, 2020 Must be a difference in knife model. On mine, 60mm & 28mm, the blade guard remains fixed and the blade is moved out to the cutting position. I no longer have the 45mm, I passed it on. Looking at the 28mm again, I reckon I can cut away some of the blade guard to make it more useful. Quote Al speling misteaks aer all mi own werk..

What do you like about that better than one where the blade is fixed and the guard moves? Edited November 1, 2020 by Arturomex Quote
