RE-Sewing a lineset...

[Kimblair13 0]

OK...suppose someone sewed a line set and did a shitty job and now they want it re-done.
Would taking all the old stitching out compromise the integrity of the line itself, or no?
Or, should the old stitching just be left and gone over regardless of the way it would look. As in cosmetic not an issue.

Can you provide more detail on "did a shitty job" and what the job was? It sounds like your talking about installing a new line set?

Technically, you should be able to unpick the bartack/Zig Zag and redo it providing that the person doing the work is careful not to damage any of the line while unpicking. If they blow it though, your buying a new line set

Depends on the type of line and its thikness, but theoretically restitching can compromise the integrity of the line. For example, if the lines are really thin (HMA) improper bartacking technique can damage the actual fibers in the line. I wouldnt even ask to have the HMA picked out and restitched in the same place - just get a new line(s) :)

Un-picking bartacks is only practical if they used contrasting thread.
Even so, un-picking is a slow process, 25 times slower than sewing it properly.

Before you start un-picking, you have to ask yourself (or a Master Rigger) if stitching damaged any lines (= replacement), if it missed the inner lines (= sew again) or if the sewing is just ugly.

Remember that - on most line sets - the stitching is not supposed to carry any load. It just prevents lines from coming apart when they are unloaded, because as soon as you load a finger-trap, "it ain't never gonna slip."

As long as you start with a good needle, a surprisingly few ugly stitches (straight, zig-zag or a variety of bar tacks) and lines will be structurally sound.

I am not trying to defend sloppy stitching, rather I am trying to say that un-picking and re-sewing the lines will do more damage than good.

Depending what the "ugly" issue is it might be cheaper to install a new line set. Un-picking every single stitch on a complete line set is going to take hours, many many hours. If the stiching just looks ugly but is structurally sound then over stiching the existing pattern will in all probability hide the previous job. You could ask for a discount because the work looks sub standard (assuming it is structurally sound) and use a different rigger next time you want some sewing work performed.

Just because someone has a rigging ticket, even a master ticket doesn't mean they can sew to a professional grade level, that takes many years of practice. I've seen some god awfull sewing jobs over the years that looked like crap but were structurally sound and done correctly, just looked like crap is all. Hope this helps you out. If you're unsure about it ask a different rigger that you trust.

Looks scary, but structurally sound. I think that's all it is. We'll see.

what everone else posted and,DON'T SEW OVER EXISTING BARTACK. Post pics and get advice from other riggers by showing them the stitching. Also, a stitch is 2 threads that 'loop' each other during sewing. The 'loop' is the 'knot' of the 'stitch'. The 'knot' should be in the middle of the material/line. If the 'knot' is on one side of the line consistently throughout the kit you could have problems with the stitching coming undone.
