Husqvarna 12 705

Mike, no doubt you're right. I used to have a Husqvarna lawnmower that converted into a snowblower for winter! I called it 'the orange beast', and let it go when I sold the kennel. The new owners have put it through all sorts of abuse, even using it to tow a toolshed from one side of the property to the other, and it's still going strong!

Also, is it possible to change the motor to a slow speed home sewing motor that could be suitable for light leather work. Which motor would that be? 

Basically, you can put any motor you want on them. But as you already have one machine with motor you can use that, just make a speed reducer with different size pulley/pulleys to slow the machine down.

I don't think the motor is working. I tested it. I've purchased a small 90w replacement motor for one of them. It's the one which comes in a box without the table. If it works fine for sewing small thin leather items like wallets with 3-4oz X 2 then I'll probably get a bigger motor for the table version machine to sew canvas bags. In the manual it says it can take needle size 140. That means thread size 92 could be just fine.

Just wondering if there is any video or resource to do a complete overhaul of such type of machines. Would help a lot.

Not sure if there is a Husqvarna group on Facebook, but there are old sewing machine groups.  Many different domestic ones and some have files about refurbishment.  There are also some old forums on other platforms.

I'm sure there is a service manual for those machines too, but I made a quick search and was unable to find one. I have come across several manuals for the two main Husqvarna generations that came after your machines (the automatic & 2000 series, I use those), so you can probably find one for the class 12 too, if you just look in the right place - asking in the right Facebook groups may be the best bet. If you don't find one the good news is that your machine should be rather simple by comparison, the newer zig zag & pattern seam machines have A LOT of extra adjustments to get right in those systems.

It is an old machine but a good one, it has more piercing power than most of the new domestic machines. When we buy an industrial machine we presume it is the best machine out there which is normal because we all take pride in what we own. I ended up buying a Brother industrial sewing machine because the owner of the tailor shop was buying new machines, Juki was the brand, he told me the machine he gave to me had more piercing power than the new Juki model he was buying.I have to check the model of the Brother as it is packed away with other machines. A lot of the older industrial machines are just as good as the new ones.
