We have found the Groz-Beckert GEBEDUR titanium nitride coated needles to be good quality and very long lasting. They have significantly reduced thread shredding. The coating reduces friction and frictional heating.

The bobbin case opener adjustment is performed by loosening the screw holding the opener. Adjust it so it moves the tab away from the edge of the notch in the needle plate as the thread goes between the tab and the notch. If it is properly adjusted the thread will not hang up or shred.

Look up a Brother Luminaire combination sewing and embroidery machine with a scanning capability and a pattern projector. It is priced in the 5 figure range.

Normally the gears are greased and everything else is oiled with sewing machine oil. Red grease stays on the gears and doesn’t harden like some others.

The purpose of part 1 is to rotate the bobbin case to open a space for the thread to pass between locating tab 4 and the notch under the needle plate.

I have purchased from Bally Ribbon Mills for mil-spec tape and webbing.

I would suggest you use some sticky grease as part of the assembly process. I have had to use grease, tweezers, and a dental pick to assemble needle bearings.

One configuration that works well for me is a Singer 212W140 with a Galkin puller. It is a needle or compound feed and the puller provides a positive feed without marking the top of the material. The 212 lubrication system has a reservoir under the top cover with a weight on a spring that makes waves in the oil that transfer oil to the wicks. The hooks have reservoirs under them that are supposed to supply oil to the hook race but you need to check to see if it works and oil manually. There are several oiling points that the wicks don’t reach that must be oiled manually. There is no oil pan, just a drip pan.

You could also check out using a water jet cutter. It wouldn’t have the same thermal effects as a laser.

I see you were using this thread in a Puritan Low Post. Do you have any information about what Puritan needle size corresponds to particular thread sizes? I have recently acquired a blue Puritan Low Post but have not yet set it up. I have the parts catalog but no operator’s manual. The machine is mostly complete but has only one needle and one awl that are .050 diameter. Any information would be greatly appreciated.

When we order from Wawak we get shipments the next day from their warehouse in Sparks, Nevada.

On the Facebook Vintage Industrial Sewing Machines group Robert Collier posted a video of a machine demo attaching patches to hats. He is a good resource for determining the best solution for your application.

The 135x5 needle is available as a 134MR (multidirectional) which has an offset scarf and a stiffer shaft. It can be set with the hook closer to the needle and it will sometimes make the loop easier for the hook to pick up.

A thread sock is frequently used when the thread falls down the cone or “puddles”. It can add tension. An alternate solution is to use a foam pad under the cone to prevent the thread from catching under the cone. An unused mouse pad works well.

The titanium nitride coated needles run cooler and 5 to 10 times longer than standard finish needles. Groz-Beckert labels them GEBEDUR.
