Which needle system and bobbin size do they use?

[Wizcrafts]

Some of them I see advertised use a household System HAx1 needle. That would really limit the thickness you could sew.

[Frodo]

I use HAx1   size 20    I have  size 21 on order

for parts /needles/thread  seek out   bantam saddle tack

he has bobbins.

The Chinese patcher's can be converted to a more standard 135x16 needle series fairly easily by adjusting the needle bar up about 4mm and opening up the bobbin cover plate hole slightly to allow for the larger needle diameter. The bobbin size is it's main downfall from a sewing prospective. The bobbin is really small which means less available bobbin thread thus shorter seam lengths before having to do bobbin changes.

Mine came fitted with a standard domestic needle but it wasn't hard to readjust for 135x16 needles.

What size bobbins are they? Are they non-standard?

My Huji 43-6 patcher has arrived yesterday as well. It can stitch well, right out of the box. I built a portable desktop mount for it, out of a sofa foot and a hardwood flooring board. Looks ugly but functions well.

Then I went to motorize it, thinking that a domestic motor would work, but bummer! I need a CW motor whereas domestic motors are CCW.

My next question is: are HAx1 needles available in LR point at all? If they are not, then how can I adjust the needle bar for 135*16?
