NobbyHall Report post Posted November 15, 2012 Hi, I'm new to this site and have had trouble finding answers to a question via the search tool so please pardon me if I'm asking a answered question. Some time ago I was given a 29K71. Even came with a supply of needles and thread although do to how these had been stored the labels were unreadable. After recently repairing the machine, having run out of thread and lost the needles after a move I need to ask a basic question. I have a guide for the needles that can be used in a 29K71 which also shows the thread to uses per needle. It does not give any indication as to suitability against leather thickness. So I'm not sure, for example, what needles and thread to buy for leather 2mm, 5mm etc. I either sew shoe repairs or fairley thick stiff leather between 5 & 10mm. I was hoping someone might be able to give me an idea of what needles and thread to use for general all round repair work and for the thicker end of the scale. Also, when using the largest needles and thread, what is the best bobin thread to use?. Any answers greatfully received. Regards. Nobby Quote Share this post Link to post Share on other sites
Art Report post Posted November 15, 2012 For me, 69 or 92 were the best working threads using a 20/125 needle. You can try 138, and use 69 or 92 in the bobbin to make it last longer. You would use a 22/140, 22.5/150, or a 23/160 needle for that. I have it loaded with 69 and an 18/110 and don't stray from that very much. The patchers weren't really designed for heavy sewing, and I do that with another machine. It is very handy for sewing a patch on a sleeve, and 69 is just fine for that.

NobbyHall Report post Posted November 19, 2012 Hi Art, Many thanks for the reply. Can I ask what would be your recommendation for a machine for heavy duty sewing?. I do a lot of handbell and tower bell leather restoration that requires sewing between 8 - 25mm (5/8 - 1 inch in old money) of stiff'ish leather. Up to date, I've been doing this by hand but demand is wearing hard on my hands!. Regards. Nobby Quote Share this post Link to post Share on other sites
Art Report post Posted November 19, 2012 Hi Nobby, For stitching !" or so, a 441 clone set up for leather and modified for in excess of 1" lift would be a good bet. Some of the suppliers in the banner ads can supply the 1" modification. These machines work with either Polyester or Nylon left hand threads. Another option is a Campbell machine which is hook (needle) and awl and can sew an inch in the standard configuration and a bit more in the high lift version. The Campbell would be able to use linen thread in addition to synthetic if you need it for restoration work. Art Quote Share this post Link to post Share on other sites
