dikman Report post Posted February 17, 2016 I just fitted a new servo to my post-bed, but it's decided to be non-cooperative! It has a tendency to break needles, and it's a bit scary. I was testing it on 4 layers of thin cardboard and after about eight stitches "twang", another one bites the dust. The problem appears to be that the slightest deflection of the material (cardboard, leather, material) sideways causes the needle to hit the needle plate, which can only have one result!! I decided not to waste any more time on it, and while casting some boolits I was staring at the machine and thought "why not fit one of my other machines to the table, and make it useful?". While the width of the post-bed base is the same as the WSV77 and 331K4, the length is shorter (but both of the others are the same size). So, after much cutting, routing and filing I fitted the WSV77. Wonderful, now I had another working machine. Then I thought I'd better try the 331K4 - wouldn't fit! . The length and width were right, but the underneath of the bed had wider bumps on it. More (careful) rasping and fitting, rasping and fitting and eventually it dropped in. Success, a quick trial and it was stitching too. The job isn't particularly neat, but the cutout in the table was already pretty rough so it didn't have to be perfect. I'd previously fitted a home-built reducer on top of the table, but in order to fit these machines I had to modify it by welding it to a large hinge so that it could be tilted back to tension the top belt. By doing it this way I'd inadvertently made it easier to swap machines - loosen off a locknut, back off the adjustment bolt and the reducer tilts forward to slacken the belt, remove belt from machine and lift out. Easy. I'm feeling quite pleased with myself . Quote Share this post Link to post Share on other sites
