I started with a few different home machines. The Singer Slant o matic as stated worked fairly good. It would use v69 thread, but not the v92.
I then found a used Sailrite Sailmaker
. Not sure if Sailrite still sells it. It's a Brother machine with a heavier presser foot spring. It was a fine smooth running machine.
Here are some things I have come to find handy for canvas and upholstery work:
12" throat stapler from office supply store.
Forget pins, staple it together.
Staple remover. Not the claw
Soap stone for marking. From welding supply store.
Push pins for pinning to table.
Double sided seam tape.
Grommet setting tools. Use "spur" gromets. They use a different setting dies.
Snap setting tools. "Press n Snap is a great time saver.
Hot knife is great on Sunbrella, as it seals
A circular cutting tool cuts good, but doesn' seal.
4' or 5' aluminum
straight edge ruler.
12 or 18" ruller.
1/2" batten, for enlarging a pattern to allow for 1/2" seam allowance.
Punches for 'lift a dot" and "common sence" fasteners.
I upgraded to a real walking foot, actually a compound feed machine (Singer 211w165) Compound feed, is where the needle moves with the feet. This is the machine type that Upholstery shops use.
And if you need any zippers, PM me. I have marine
#8 zipper for $1/yd and the pulls for $.50/each. Also have #10 continuous zipper.
Also have snaps, etc.
Good luck with the sewing.
