Hey Craft punk.
I collated some info regards sewing machines if you’re interested.
From what i understand we want a industrial sewing machine, some thing that will sew leather and is indestructible/unfuckable.
Industrial machines are usually fixed units including a table. So it will need and specific space allocation. Industrial machines can only sew dress leather, not some one sewing thick armour for cosplay.
Machines that specificaly sew leather cannot necessarily sew garment fabrics.
Further more, damage to an industrial sewing machine is expensive to have repaired.
There are affordable second hand industrial machines. The advantage is they can sew thick denim, like jeans. Which is harder to do on a domestic machine without experience.
Unfortunately, there is no such thing as an indestructible machine. Like most other things at the space, damage is user error, comes down to inductions, communication, and servicing the machine.
So the suggestion from me and my people is to service the brothers, particularly since when they are damaged from misuse they are easily repaired and cheaply. And if anything buy a second hand industrial machines as a fixed feature. The only advantage of which is to sew thick denim.
