3x0.5 thread
You can tell if an old $20 bill is fake by holding it up to a light source and looking for a security thread. If the bill is real, it will have a vertical thread embedded in the left front side. If the bill is fake, the thread will be missing.

Take the thread through the first thread guide which is on the right, then through the needle guide notch. Wind the thread around the tension dial and pull up to the left of the dial. Pull the thread into the thread guide at the bottom. Take the thread from front to back through the needle eye.
No it is not reverse thread. The passenger side rear spindle is the reverse thread on 88-93 festivas.
The Baikal 628 typically uses a front sight with a thread size of 6x0.75 mm. This is a common metric thread size used in various firearm applications. If you're looking to replace or adjust the front sight, it's advisable to verify the size with the specific model, as variations can occur.

The thread must come from the FRONT of the upright spool on the back of the machine. Thread through the small eyelet on the back (nearest the spool(s), projecting from the top), then through the thread guide at the front of the machine. If you are using a double needle (therefore two spools of thread), the thread from the left-hand spool should go through the top hole and the thread from the right-hand spool through the bottom hole. Come down to the tension disks. Bring the thread through the back disk, up again under the wire guide, and down under the thread guide that is just to the left of the tension disks. Bring the thread through the eye of the take-up lever (the piece that moves up and down when you sew) from RIGHT to LEFT. Guide the thread back down through the thread guide next to the tensioner. There is a little thread guide just inside the door on the left side of the machine; bring the thread through this guide. Then pull the thread through the wire guide above the needle (it's easiest to hold the thread horizontally to do this). Thread the needle front to back. HTH. YMMV.

To thread a Sun hand sewing machine, start by placing the spool of thread on the spool pin and guiding the thread through the thread guide. Next, pull the thread down through the tension discs and then up through the take-up lever. Finally, thread the needle from front to back, ensuring the thread passes through the needle eye properly. Once threaded, pull the loose end of the thread to ensure it's secure in the machine.
