Setting-up Binders is never easy, and it hard to get into specifics on doing a setup to Bind with internet forum pic. and not actual seeing, and with not having hands-on the binder and machine . Getting the correct Binder, and with Binder in proper set-up . That goes with equal detail with seating-up on the positioning of Binder to the presser feet, also the shaping of the feet to accommodate the binder position to Needle for feeding materials. Plus a few other things. After that it's all about building your personal technique for Binding. Sounds like your saying, your biggest struggle is getting the binding material of choice to track out the binders throat nice even with feeding material ? , and the Pic. of the, 1"/25mm Binder to me ?, looks like that binder is for thick edge, it looks to have a pretty tall open throat height . your 1st choice on binding is, 1" wide, type lll grosgrain ( tape binding ) ? ( for me/just my opinion ) .. On thicker edge materials, ( exposed, finish look ) and using 1" wide Binding for a wrap. My 1st choice is a type ll, #4082 herringbone . Binders throat height around the 12mm size . And for ( exposed finish look ) for the thinner edge binding, 1/8' and thinner edge. I always go with a 3/4" wide type lll #5038 grosgrain . also the binders throat height around the 5mm size . .

ya .. a nice Magnifier for sure , and also some 'soft' super-fine grit emery cloth for smoothing Hooks and also need something to remove nick's on needle plate, and other sharp spots ..etc. that you run across. edit add: Besides a nice tool carry box for repair and cleaning . Also I seen some repair techs. run a hang-harness/ chest mount that has a lot of common small hand tools at easy reach . Also...LOL you will be cleaning and blowing out a lot of thread and fabric Lint and oil everyday, If a machine is run for 8 hr. shifts it's incredible the amount of filth they accumulate. .

Looks like ? , in the Vid. . That your outer presser foot not lifting also . .

I have never seen anyone with branding a Machine head with sales name 'Mach3 ' as logo ? Only cross reference in the name . if type in general search , ( Mach3 sew ) The only thing that I could see connected to sewing was Longarm Quilting machines, and Mach3 software stitch/pattern programing. I seen that machine you asking about advertised in the craigslist/salem OR. , their asking 2500-$. it looks clean and head is a complete set-up w/table and drive. It is/looks like any other 441 clone, and i have noticed asking/pricing is all over the place right now on used sew machines. 2500-$ is little high for used but not unreasonable ' if ' you are real close to area for you to easy pick-up . also price not unreasonable if has a lot extra's with the machine ? feet, Dogs/needle-plate set-ups, or binding or other attachments ? You saving minimum about 700 to 800-$+ over buying new . ( this for example ) , if you buy new from dealer on west coast here, You are in WA. like from artisansew down in bay area CA. you going to pay 3000-$ and change, and plus at least 200-$ 4'x4' pallet truck shipping up I-5 N. to a shipping hub for you to pick-up. .

Sounds like the machine was misused and monkey mechaniced by the previous owner . If all is in time properly . The going Slow is Fine, and the Fast RPM is Bad on thread could also mean simple problems . Maybe some needle strikes. Check real close for a Burr or a Nick in your Needle-Plate, smooth-out with fine emery . Check for Burr in the Hook, take piece of cotton ball or Q tip and run it across Hook. If any snagging, smooth it out. In my life I have even run across/pulled-out a couple new Needles out of the Pack also that had a 'sharp Eye' inside-edge that would also shred Thread . .

should be similar/same watt set-up as this older Artisan 3200 I have had for several years, good watt, programmable servo and added reduction. mdl. ( ACF-622 b brushless servo ) - -

Your machine should be a 135x5 needle right now ? , Your machine is pretty common. just figure out what DB Model MITSUBISHI, that is looks like and go from there for info also . Needles like 135x5 is perfectly fine. Your machine isn't doing any bigger than #69 thread anyway. 135x17 offers a little bit bigger needle thread hole for larger thread, but you wont need it. It a good learning experience for you and changing out a few things on this bottom-feed machine, and will be good basic knowledge, and be pretty helpful when you moving-up to a better machine latter on. 'Basic stuff ' like this translates over down the line. You changing out Needles , Dogs, needle-plate, Feet ...etc. that is real economical ' for your machine . Just go on Ebay for presser feet, or a roller foot . If just using standard presser foot, just buy both a Large and a Medium Dog and needle-plates to play around and see which feeds best to what you doing . You might not even need to go to the largest tooth Dog . -------- Your machine will stitch thinner leather . It is just that a unison-feed, or a drop-feed walk has far better feed and needle control. I threw a couple Pics. in to show you. I cut a piece of old scrap leather/deer . It is average @ about 1.33 mm thick. it still fairly supple but Old. I doubled 2x thick, and it was about 2.70 mm thick . . then tripled 3x thick to about 4.50 mm thick .. then 4x thick to 5.04+ on the Caliper . I did Little effort on my end, I just used what #69 that was already strung-up on the machine and the 20# needle hole round point fabric needle . It just sewed it all on the 1st attempt, no practice scraps before I took the Pics. I keep an old DB-170 Mitsu. and I worked it over to Feed heavier cordura/webbing with a better servo drive,and 135x17 needle, higher tension . 69/T-70 is the limit on thread size. - -

Nylon is structurally stronger and more abrasive resistant than Poly . Poly is more UV resistant than Nylon . Both Nylon and Poly have there versions of ' satin soft ' threads. .

It sounding like you have zero, or very little knowledge of sew machines in your Post. So It a 1st time, low budget machine, if just starting out learning . learn some machine stitching basics, needles, thread, and machine working mechanics with using it...---> Save your money and work on getting a Consew 206, or Juki 1541 for future expansion of your skills . That is a pretty common Mitsubishi cast head, used on many brands, and is a Drop-Feed ( bottom feed ) . it a light-Med. duty sew machine. OK.. It will 'can' sew leather . at a minimum expectation it can do some decent stitching on thinner softer leathers. 'if' you change a few things with it. But you need to put some time 'sitting behind' getting to know the machine. Also the machine ( it is , What it is ) you got to recognize it's limitations. It takes easy to find selection of Feet, Dogs, needle plates, Needles, and also will take easy to find presser roller-wheel. The Roller Foot, is an easy swap/change-out, and it also can do some decent stitching . You can tune it for 135x5 and 135x 16/17 size needle. It will use #69/text 70 thread . it has small bobbins . It does have Reverse, but you will 'try and try' to adjust, to get it to sew same SPI in reverse, but it Won't ever never be satisfied with stitch quality in reverse . It is set-up in your picture for Fabric Stitching . For sewing Leather. You need to get needle control, slow it down, get a quality servo. or a cheep servo drive with using a reduction pulley . You going to have to change out the Dog and needle-plate, to a Med. or Heavy tooth, and get rid of the fine fabric toothed Dog . put in a little heavier tension coil spring on top thread. experiment with the presser-foot tension. use a smooth/slick chrome plated press foot . .

Looks good for it's age. 450-$ is not a bad price at all for machine in Pic. as long as it sews . There is a reason people still buy and sell them. Patchers can reach in, and stitch were no other machine can get into. and ( Yes ) they are handy/effective to have in your machine stable . ( for me ) It one of those machines you don't use often, but when you do use it.. You REALLY Need It, and glad you got one sitting in the corner. .

That guy is a magician with a sew machine. Have you seen the Vid. of him making his own piping foot set for French Seam ? . Cut out of a hunk of scrap metal with hand tools, for his twin needle Durkopp&Adler 268 FA-373 French Seam piping, Scrap Metal Feet set -

Sailrite did a couple good examples, on doing two turn-corner techniques with French Seam. Turn-Corner, French Seam -

I have paid that and more-$$, for older machines , BUT ( My opinion ).. I would never pay 575-$ for a machine in that Poor condition, of that age . I can imagine how the drive looks ? , and It my lay down a Stitch, but that head and table look like it has ' already seen it's better days ' about 20 years ago . .

New to industrial sew machines, and buying that 1st machine that is double needle ? Sounds like you want double the frustration on your learning curve ....LOL The double needle maybe a good buy, and you can use it for certain stitching . But it would be better for you to pair the Double-needle as secondary station, with a good Single-needle machine as your primary, as the single needle will be the one you sit behind the most hours for a daily workhorse. .

I pretty sure that the ( H3 ) is factory designation on the dedicated binding feed model of 335 . I would not mind finding a good deal on a older clean little 335 H3 head for tape binding . I for most part use needle-feed flatbeds for binding, but I have one cylinder arm unison feed right now set-up for binding also . So seller only selling you 335 Head only ? no table or drive ? . If you buying the 335 head from seller just take your time and string it up and turn it over by hand on some material to make sure it feeding and lays down nice stitching before buying. .
