Yes a small compressor is great....on longarm there are no secret little places for lint to be blown into as on DSM...it will just blast it OUT.....
On mine I have two yardsticks....that I slip under the side clamps..one on each side. Close to the clamps...raises them just enough so the sewing head does not get caught up at the edges......
Also bought two old fashioned curtain rods and a lipped cookie sheet...put rods over take up rollers, screwed on cookie sheet and it is a little shelf on which I have my snipped thread catcher...empty Kleenex box, tool caddy which holds large scissors, dry erase pens(to adjust panto, if necessary) ,large scissors to trim sides, pin cushion with a few pins for "just in case"...
Instead of lanyard for scissors I use one of those things you attach to shirt and your scissors are on a string that is spring fed on this thing....and the snap back close to your body....don't know the official name...but this way scissors are not in the way, hanging from neck
Each finds little things that make their longarm journey more efficient.....have fun
