[QUOTE=somanyboats;2619507]I have a phaff 130 , works great. I have sewn many layers of sunbrella and have done
repairs on our sails.

Thank you for accepting me to this forum. I am not a sailor, but I have used a lot of information about
rigging, webbing, ropes etc.
for the use in gymnastics and similar sports. I hope to be able to provide a bit of information back regarding some sewing machines.
I think that a good
sewing machine for use on boads is the Sailrite machines and similar machines. It have got a walking foot, and it is very nice when sewing heavier fabrics to get good feed traction on larger heavy and larger fabrics. However it do also have some drawbacks compared to some of the capable vintage sewing machines. The Sailrite is heavier, more expensive, and do not handle lighter garment
repairs as good as a normal domestic machine.
Neither the Sailrite nor the domestic sewing machines are industrial sewing machines, which are strong machines able to do heavy
work every day for years. But you will normally not need that durability for a normal machine for sailors. An industrial machine is heavy and a not easily portable machine.
I have got some expierience in making some of the vintage domestic sewing machines do heavy work. I think some of them is strong enough to do that for a limited time use. My Singer 201k have sewn 2000 m of a V138 thread and I do not see any signs of wear yet. I find a Singer 66 and a Singer 237 possible strong machines as well. Singer machines were made in big numbers, so it is still easy and affortable to get spare
parts for them.
I recommend, these requirements for a vintage domestic
sewing machine:
- The machine is by specification able to sew with a size 21/130 needle.
- The machine should have all metallic gears (normal for machines before 1970).
- The machine should have an external motor with belt, that is easy to replace for a stronger motor.
- The needle shall be threaded from the side (not from front).
- Only require zig zag, if you need it. Zig zag possibility include some compromises.
- It is nice to have full reverse stitch length. Some machines got no reverse or only half reverse stitch length.
The recommendations ensure, that the machine can easely be modified to sew heavier thread and fabrics. I think most sailors is prepared to make some modifications here and make things work in
scope of some difficulty. You need to have some basic understanding of mechanics to in order to start using a domestic machines for heavier work. Otherwise you should go for a Sailrite machine.
The no. 1 problem with domestic machines are, that they do not have the improved feed traction that you have got with walking foot machine. Domestic machines use drop feed. But you are able to do some things to improve the situation, for instance by making a thread notch in the presser foot. The feed problem cause that the
fabric may pull in the needle and bending it a bit forward or backwards. If the hook below the needle plate pass the needle behind the needle, the machine become very sensive to this needle bending and you can get the hook hit the needle or you get skipped stitches. If the hook pass the needle to the side, this problem is almost avoided. Machines threaded from the front got the hook pass behind the needle. Therefore I do NOT recommend a machine like the Pfaff 130, as some other people have recommended previously in this thread. A Pfaff 30 is a better choice, but it do not have zig zag.
Only a minor part of the zig zag machines got the hook pass to the side of the needle. The Singer 237, Some Necchi machines, some Japaneese made Kenmores and the Sailrite LSZ-1 got that feature.
I made some videos for fun (not commercial) about the Singer 201 and Singer 237 and the modifications I did on them. I hope you can use some of the information This is a video about the Singer 201 sewing vinyl:
