I have this machine for a few weeks already. Got it (head only) in a trade for Adler accessories. Machine came in a good and functional condition but I had to clean and refurbish it a bit. I have installed a complete new hook and hook shaft. Crackle coating had some chipping on a few spots but was able to touch it up with VHT black crackle paint - turned out quite good So I think I first show the ready to go setup and the tell the story a bit in reverse. ;)

Haven´t seen many of them here so I first I post some technical data in case someone finds a similar machine and needs some information:

Singer set up the 108w20 machine as synchronized binder sewing machine.

- Factory Stitch Length: max. 7 SPI / 3.6mm
- Foot Lift: max. 8mm
- Feeding System: Triple Feed / Unison Feed / Walking Foot
- Max. Speed: 2700 SPM
- No Reverse
- Arm Length up to the Needle: ~140mm
- Arm Diameter: 46mm (Hook Cover)
- Hook Type: Rotary Hook
- Thread Lever: Link Take Up Lever
- Bobbin Size: 22mm x 7,5mm
- Needle System: 135x1 / 354 / DPx1 / Sy 1451
- Weight (Head only): 19,5 Kg

Similar machines are: Dürkopp 460, CLAES 230, Singer 108K (Made in England), Singer 108U (Made in Japan)

The manual gives a god idea how to "tweak" the stitch length - I played around a bit and I´m now able to sew with approx 4.75 - 5mm / 5 SPI w/o binding. I can even adjust it to a bit longer stitch but then I have some light binding in the mechanics and that's nothing you really want - obviously. So ~5 SPI is pretty much a good sore for this machine I think and I don´t need more so I´m good with this.

"Temporary" motor is a 120Watts / max. 4500 RPM 1950´s era KOBOLD step motor (I think that's how it is called in English) in Germany we say Anlassermotor. Motor is not very powerful at slow speed but speed reducer adds some torque so it works quite well for my application. Sooner or later it will be replaced by a JACK servo but ti will last for a while I think (and hope).

The machine originally was setup for a different type of "shell binder" attachment but the one I have installed works better for the thicker tape I´m going to use.

So first some pictures of the ready set up and then I go back in time a bit with he pictures.

Will check with the Admins hope they can add the manual and parts list here:

I'm not paying 80 bucks for a belt!!! It's a strip of leather. How hard could it be? 4 years and 3 grand later.... I have a belt I can finally live with.

Stitching is like gravy, it's only great if you make it every day.

I used to have one like that, minus the binder parts. I took it on the road so I could sew in rooms I stayed in while traveling with road bands. I powered mine with a domestic sewing machine motor I bolted onto the back of the head. I mounted it on a 12x12x1/2 inch piece of wood.

Great looking setup you have there! 108's are great binding machines.

I love that compact stand.  I gotta figure out how to compress all my machines so I can make room for more...

Thats why the machine is mounted on an adapter plate. The 2nd machine I can use on this stand is my 29K71 patcher machine. Just have to loosen 4 screws and install the other machine which has an adapter plate too. Can post a picture later.

Sorry no information on the 108-3 - is it a flat bed machine? 108 came as cylinder and flat bed machines. Maybe CowboyBob or Gregg from Keystone Sewing know more.

Some pictures of the chipped crackle coat and the result after touching it up with VHT crackle paint

This is the new hook - actually a NOS hook for a CLAES 230 made in the former GDR but its really good quality. Hook fits just perfect I only had to reposition the from bushing since the "hub" on the hook is a bit shorter than on the OEM hook. OEM hook was attached with 2 screw to the hooks shaft but new hook is pinned to the shaft so I had to replace it completely.

Yes, it is a flat bed. Sorry for the high jack. I just got a little excited seeing anything about a 108.

I'm not paying 80 bucks for a belt!!! It's a strip of leather. How hard could it be? 4 years and 3 grand later.... I have a belt I can finally live with.
