Sewing machine

As you're planning to repair sails you'll need a zig-zag machine. I think the easiest to get hold of are the old all-steel ones made by Brother (often badged as Jones) and Janome (usually badged as New Home). The old one with a side-loading bobbin are probably the best to get. If you're sitting in front of the machine the bobbin access plate will be to the left of the needle. The old Jamome/New Home machines were mostly 500 series such as 515, 525, 535, 537. I don't know muc about the Brother model numbers from that era.

Some of the old Husqvarnas have an extra gearing in them which both slows down the feed rate and increases the power. Sorry I don't know the model numbers.

As for repairing the corners, mainly the head and clew, it should be possible with a domestic machine on the main of yacht in the low 20s LOA, which is probably going to be made from 5oz cloth. A Sailrite (not a clone!) will probably handle a bit heavier sail. Once you get up into the 40 foot yachts (not uncommon on this forum) you need a really heavy duty industrial machine built specifically for sailmaking. Then you get into the machines with pneumatically-driven needles...

Outside of the high-load areas, a domestic machine is probably going to be OK even on a large sail as long as you're not going through more than three or four layers. The challenge will always be to get the bulk of the sail though the machine's throat but where there's a will there's a way.

Thread size can be an issue. V69 should be OK in a domestic machine (use an 18/110 needle). It might take V92 but you'd need to try it. Larger needles (19s or 20s) are available for domestic machines but you'll have to search for them.

Hope this helps.

Domestic machine. Look, don’t take my word for it. Link below to an article on the subject - you’ll notice there is no mention of semi-industrial machines, even though they discuss some meaty machines by Juki, Pfaff and the like… I think what people mean by ‘semi-industrial’ is a ‘heavy duty’ domestic machine.

I have:
A modern singer heavy duty - It isn't! Just about copes with jeans. Would work well on spinnakers.
A proper industrial Pfaff - it is (a faff) but can sew spray hoods etc. Not great on thin stuff (User error I expect.)
A simple old Jones - solid, straight stitch only. Adequate.
A Huskvarna Viking with the low gear etc - Recent s/h purchase, seems pretty good thus far. Sews spinnaker cloth well, yet also reattached the Genoa's UV strip last week. Wouldn't cope with the clew tapes. I used a hammer and a nail for that in the end.
 
What type (and cost) of sewing machine is needed for repairing canvas and sails?

Where to look to find a good used one?
For canvas and sails you need a strong motor and ideally a walking foot because thick seams slow down most domestic machines. Older heavy duty Singers or industrial style Sailrite models handle this work well.

If you want to compare what is heavy duty instead of just marketing, you can take a look at what Lords Sewing has because they list the tougher Brother machines with clear specs. I’d tell the poster to buy a new one since it saves a lot of hassle later.
 
I've a Singer 20u43, a semi industrial sewing machine on an industrial table with a powerful motor. It was too fast - 3000 stitches per minute! I reduced the speed by changing the pulleys. It does straight and zig-zag and can sew through several layers of sailcloth. I have repaired sails, renewing uv strip and new canvas spray hoods etc. Spares easily available. I also have a Singer 320k free arm domestic m/c which is excellent for small sail repairs and canvas work. Does straight, zig-zag & triple zig-zag. 319k m/c similar but not free arm or triple zig-zag(uses DB1 industrial needles as original 206x13 difficult to get) Hope this helps.
 
I love my reads sailmaker if you can find one. But there are plenty of machines on ebay up to canvas work. Mine has made bags, stakpacks, series drouge (
) and the odd small sail repair.

10 years ago I decided i was fed up of waiting and paying others to do repairs. Wanted an industrial with zigzag so i could also do sails.
I rang around sewing machines shops and mobile servicing/repair guys. It was fairly succesfull as quite a few knew of machines for sale.
Ended up with a pfaff 138 in a new table for £175 which i also later learnt is a highly desirable machine.
I struggled with the 500w clutch motor as it was nothing, nothing, light speed... played around with the clutch but no improvement.
I changed to a 550w brushless/digital motor. Absolutely brilliant and so small (£65) . Can dial in the max speed i want and have full control from around 1 stich per second upwards.
The only thing i struggle with is sails around 38ft+ boat in the corners. Broke many a needle and turning by hand shows just how much power is needed to get through.
Usually if the motor is mounted to the back of the machine its low power domestic but if its under the table and belt driven its industrial.
I can lift my machine out of the table, sit it in a wooden base like a domestic singer, fit a handle to it and use it as a portable manual machine.

Well my two bobs worth . Or £960 or whatever it cost:
16 years ago (!) I popped by the boat show Solent sewing machine stand and came away with one of their zzag machines.
And some very natty scissors that will cut anything incl aramids.
They were doing a ‘load it’ deal which included the monster flywheel. It is great at smooth-and-slow for the tricky bits.

Crikey it is heavy. And I rewired the lamp and motor cables into one plug and removed the box’s top handle and replaced it with 6mm line so it would -just- store under the saloon table.

Despite all the work arounds and excellent s/h industrial sewing machine bargains that canny folk scoop up, I remain happy with it although it ‘probably’ hasn’t quite payed for itself yet .
And it’s done every curtain in this house too, some quite high and full width windows , the seams ain’t going to pull apart in a breeze🤪 I hope. Probably should have used uv proof thread though.
 
That's a lot of money for a Chinese tofu machine. I saw one today broken in a cardboard box. Was very surprised how tiny they are and not surprised it wasnt worth repairing.
Your post has gone completely over my head. You’ll have to explain.

For the avoidance of confusion, what I bought for £300+ was a very heavy walking foot Sailrite LZ1 sewing machine which I believe was made in the USA.

Iirc, sailright machines are rebadged Chinese made ones with good marketing
