TheHollerLW Report post Posted November 4, 2020 Noticed tonight some bit of smoke after sewing for 30 min, I changed needle and still same result. I cant seem to find any other parts with heat in bobbin area, just needle. I re threaded as well. Also let it cool and just ran about 50 stitches and it was hot. Thanks Quote Share this post Link to post Share on other sites
Arturomex Report post Posted November 4, 2020 (edited) I'm sure someone more knowledgeable than I am will be along shortly. In the interim, what are you sewing? Type of leather and weight? Speed? And what thread and needle sizes are you using? Regards, Arturo Edited November 4, 2020 by Arturomex Quote Share this post Link to post Share on other sites
Constabulary Report post Posted November 4, 2020 Hot needle are normal when sewing dense / thick materials. And the higher the sewing speed the hotter the needle. Nothing unusual. There are needle cooler available if thats an option or a thread lubricator may reduce the friction a bit as well but not sure if that works for you. https://www.google.com/search?q=sewing+machine+needle+cooler&client=firefox-b-d&tbm=isch&source=iu&ictx=1&fir=VubgucjcRKI7IM%2CVfRYIl9y3fqOXM%2C_&vet=1&usg=AI4_-kTRBX3MAqPDlYixlgbu0EyCmn8Ygw&sa=X&ved=2ahUKEwi14KOBuejsAhWGqqQKHaVCCmQQ9QF6BAgFEEc#imgrc=VubgucjcRKI7IM https://leathermachineco.com/product/magnetic-thread-lubricator/ Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted November 4, 2020 Yes,as Constabulary said there is heat involved from the friction of the needle going through the material.As long as it isn't burning your thread it not something to worry about if it does burn the thread either slowing down or lubing the thread will help.

Wizcrafts Report post Posted November 4, 2020 If your machine has a lube pot on top, buy a quart of silicon lube and fill the pot. Run the top thread through the lube pot on the way to the top tension disks. If you don't have the lube pot, contact Bob Kovar to get one, with the required threaded bolt.
