Cascabel Report post Posted April 27, 2014 Can anybody tell me how to dismantle a Singer 29-4 far enough to get to the feed cams for repair or replacement ? I have welding and machine shop capabilities, and I think I can probably build up the worn areas, and re-shape them back to close to the original contours. I just need to know how to gain access to the parts. I believe it would involve taking apart the cylindrical part that the needle bar goes down through. I need to know if there are any particular problems in disassembly/re-assembly that I need to consider in the project. The machine still functions quite smoothly and reliably, it just won't give the stitch length it sould be capable of. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted April 27, 2014 You have to pound out the tapered stud holding the needle bar to the take-up barrel. Then loosen the screws on the right side of the head portion (I think there are 4) and remove the entire barrel shaped head. Remove the needle bar from the bottom. Remove the presser foot and stitch regulator "puck" (my description) and screw. With the bottom facing you remove the two screws that secure the feed ring to the head. The feed cam comes out of the ring in which it revolves. You can bronze braze material onto the "puck" that fits inside the ring, then shape and polish it for best fit at 360 degrees without binding. This yields the maximum available stitch length, which is usually 5/inch (unless you live outside the USA, in which case you cannot have anything to the inch!). When you're done repairing it, grease the ring and reassemble in reverse order. Quote Share this post Link to post Share on other sites
Cascabel Report post Posted April 27, 2014 Thanks, Wiz. Being that it is a tapered pin which must be driven out, it would be helpful to know in which direction to drive it !! I don't want to drive it in the wrong direction and just make it tighter. Do you consider bronze material to be sufficiently wear resistant, or might steel be better ? I can do either. I have several other projects in the works right now, so I won't get to it right away. Quote Share this post Link to post Share on other sites
pcox Report post Posted April 28, 2014 All of the pins I have removed from 29-4 drive out from back to front, the large end is toward the front of the machine. Take a good look or a picture of the levers on the back side of the head before you remove it so you will know how they go back together Quote Share this post Link to post Share on other sites
