  1. I've fitted several needle positioners(inc. a juki 563), mostly I've drilled a hole in the side of the machine and tapped a thread in the hole.Its probably possible to do it another way but you would have to get creative with some bracketry.
  2. I've also done this but on a servo motor machine.I've extended both the pedal arm and the controller arm, possibly only by a few inches on each but every little helps.
  3. Wow. I saw the title then looked and saw it was something I posted. Easy fix although not very helpful to other people. After hours of messing about trying to get it to work nicely it got stuck in the deepest darkest corner of the workshop and I bought a secondhand newer global machine.This one works really well without all the hassle of sharpening, twiddling this, twiddling that and still getting nowhere.
  4. Thanks all. Its my bosses machine and any repair won't be an expensive one so unfortunately that rules out the efka option. I did have a quick look under the covers and spied the various solenoids and air cylinders and did think about a switch to opperate the right solenoid.I'll have another look when I have some spare time.When I bought my own machine it had all the electric options but did have a hand operated foot lift but no knee lift, I did find it had a spindle underneath that I could connect up a universal knee lever. Shame this doesn't have the same.
  5. We have a durkopp adler n291 at work that has the all singing all dancing electronic everything..............unfortunately it doesn't work.There is some fault with the efka v720 control unit or the motor, now an easy cheap fix would be to replace the motor and control unit with a new servo motor but the machine doesn't have a manual footlift. Does anybody know if it can be retro fitted or if there is another way around this?
  6. I found that my skiver(no vacuum) would pull the waste back up around the feed wheel, I've since changed the stone wheel for a yellow rubber one and this(so far) has completely solved this problem.Saved me a lot of work in fitting an aftermarket vacuum.I think it also has made the feed easier or smoother, a very worthy modification.
  7. I have this machine with an efka control system not the 720 but a i70 motor and c300 panel.It probaly does the same as the 720. I have a few downloads if you go this route
  8. I found the best change I've done to my skiver is to replace the stone wheel with a plastic/nylon one. I had problems with waste material being drawn back up over the wheel, change of wheel resolved this issue.
  9. Having a skiver set up correctly in my mind is worth paying the extra as one that needs setting up will really cause frustration.Where I work my boss bought an old fortuna second hand and with no amount of fiddling about could I get it to work with any consistancy.I myself bought a newer but again secondhand chinese version and ended up paying a technician to set it up.While it may look more simple than a sewing machine you have spring tension and angle of feed roller plus height adjustment, then you have left/right adjustment of bell knife, also height and angle of pressure foot adding into that the fact that if you adjust one thing it can vary another adjustment.Material of feed wheel can affect how it pulls the leather into the blade.Owning a skiving machine and getting it to work correctly is a contant education.
  10. To be honest I have no idea how its set up, I just bolted it on so the material to be bound was in roughly the right position with the needle in roughly the right postion and it seemed to work. Its to be used for binding carpet with vinyl material but the thickness of the vinyl causes it to stretch slightly so I need to get a binder with a thicker gap for binding material.
  11. This is how I mounted a binder to my machine, I need to change the binder size but should work well like this.Also nice and easy to fit or remove.
  12. HoHsing i70 manual, keep scrolling through and its english after the chinese version. http://www.hohsing.com/download/i70m-manual-tw-en.pdf http://docs.makini24.ru/Ho-Hsing/Manual_HVP-70-4-ED_2007-01_IMCA.pdf
  13. They both look like servo motors to me, I guess you just lock the controller box a what speed you need. I'm still looking at doing this mod to my skiver but I'd like to get both motors under the table.
  14. Great idea, I did go smaller in size with needle but as we didn't have bigger I couldn't try.I will order some bigger to try. I did forget to mention but with the previous machine I used, a juki 563, and the same sized needle and thread this material sewed fine.
  15. Thank you, good to know what the sizes are. Unfortunately its not fluff as I've since had the shuttle apart when I had some thread jam it up. Picture of vinyl lower face.
