White 1740 Quilter's machine
I can't get an even stippling stitch because it is impossible to adjust the bobbin tension with the White 1740 Quilter's machine ( bobbin tension is too loose).
Also, the top tension adjustment seems almost to be a dummy dial that is not adjusting anything.
Secondly, to drop the feed dogs is very inconvenient. The button for that is up under the extension table and very hard to get to.
Thirdly, I've had the White 1740 Quilter's machine for about a year I guess, and the control buttons such as "stop", "slow", and "needle down" have stopped working altogether.
Also, the carrying case immediately failed to close; I have to duct-tape it closed!
I will not be purchasing any more White machines.
