Gritzner Frobana Outsole Machine

[SenttRox]

Thanks guys I tried with M6x1 and it worked but somehow it seems that I can't get the movement unles I pull the leather. Does the spring on the screw plays any role? 

Could the feeding teeth be inserted wrong? 

I'm also looking for oil intake niple. Are there any available?  (Pic) 

Thanks

You may need to lower the head to press on the leather for it to move along?? It is hard to see from your pictures?? when you lower the head does it press on the leather??

[Constabulary]

There should be a thumb screw under the front lid with this thumb screw you can raise and lower the head (the thing that looks like a fulcrum beak) It is like the presser foot on regular machines it puts pressure on the materials and w/o a certain amount of "foot pressure" this machine will not sew properly. If you have problems adjusting the head height turn the small checkered wheel (looks like you have a wheel instead of a lever) a bit to the left while turning the thumb screw.

Do you have a manual for your machine - if not send me your email address by PM

Can you post a few full view pictures of your machine?

The thumb screw marked on pic....

I would be grateful for a manual.

Attached more pics, i just bought it and would like to set it right.

technically it seems to be the same thumbscrew but your machine is probably the earlier model I think. But the manual seems to be right for your model.

Manual is on the way.

I think first of all you might want to look for a smaller bobbin, that way you can get tension on the top thread. By the looks of it, that big cop of thread will not let you get the proper tension. It consists of a felt or leather washer each side,spring cup washer,spring and nut. Remember 1 1/2 times around the first tension pulley.It might be just the position of your wheel but the head looks really high?? You normally put the leather under and adjust until it is just gripping when the arrow on the machine is in line with the one on the hand wheel. I have just noticed that your arrow is missing?? Looks like it has been worn down where it was. There are two kinds of feed dogs for this machine, one is for rubber soles with two teeth like the one you have in the machine and the other is for leather soles which is a knife and a small point. If you are sewing leather then change the feed dog to the knife.

This may be a dead post but,,, I have tried all the links to parts and needles and none of them work. Does anybody have current information on parts and needles for Gritzner and Frobana? I have a gritzner and want some spare parts on hand.

 

Thank you

I hope it's okay to post here. I need help please, in threading the upper thread. Its not like the double disc sandwich on my other sewing machines, and also i dont see a tension control spring or any other tension other than that on the thread spool itself. Its an old Frobana, serial number 5925.

Can be repaired by a TIG welder or made on a mini lathe. Sometimes this is even worth ordering custom dies or taps for. I could even solder it back together.

Tip: the stud does not have to be split.

Thank you SO much, how exactly and what is to be welded and / or made on a lathe?? More details would be very nice.

This thread you started has been very helpful, but my Frobana is much older and the configuration of my machine is different.  

I believe the part you had to fix was the tension on the spool of thread, but I am concerned about  the section further towards the head.
