I'm eyeing a highline setup with great position but no means of setup using removable gear. How many bolts are needed to make a reliable slackline setup? What factors should be taken into account (length of line, angle of bolts, equalization, etc.)? Realizing of course there are so many variables involved, is this a reasonable thing to consider?

slack lining does not justify defacing the rock with bolts.

Haha...that's a good one.
Funny how slackline bolts (which are much more visible and much less necessary) are left alone by the valley mafia, but we all know what happens to other bolts.

dragon-
it all depends. how long is your line? what type of rock will you be drilling in? will others be repeating the line? Something that weve done before drilling bolts for highlines is have a buddy one one side of the gap and you and you on the other side. stretch a rope (or webbing, doesnt matter) holding it only with your hands, this will give you a pretty good idea of what your line is gonna look like and weather or not the line is worth bolting for. scope it first before drilling.
Mick-
the mountians and crags are here for all of us to enjoy. slacklinning is another form of enjoyment and takes a large amount of skill to properly rig, let alone walk. if nobody complains when bolts are drilled for a sport route, nobody should complain when bolts are drilled for slackline anchors.

The intended line isn't particularly long. Looks about 50 feet. Hard sandstone (more like Fountain than Wingate). Will see repeated use by a few of us, not just a one-time deal. The location is not sensitive to bolting, is not on climbable rocks, and is close to a trash dump. Local fisherman pour concrete over the rocks to make steps to the water. Mick's point, which is certainly valid under some circumstances, does not apply here. It will apply next week, however, when I post a question about drilling sixteen bolts (by hand) to set a line between the summits of Lembert Dome and Cathedral Peak.
Back to my questions - anyone have a clue as to how many equalized bolts I'd need at either end of my trash-infested roadside quarry non-native peoples use sited slackline?

I think 1 bolt should be fine.

Personally I do not have a problem with bolts, whether place on lead or rap. I just thought I would be an antagonist. I just think that no matter what the circumstances bolts should be considered as a last resort and the costs and benefits thoroughly considered before bolts are placed.
Bolts in a dump-go for it.
Bolts on a sweet line in TM-just as good if the circumstances dictate.

Dragon,
In sand stone be careful. Glue-ins would be best but they are expensive, if you have the funds- go for it. But if not place three, three in. rawl 6 pieces on each side, half-inch would be best but 3/8 would probably do fine. You could try some hardware store bolts, the ones where its mostly the threads but at the tip its the sliding shank...I tryed to put some of thoes in for a line in sandstone and they didnt work so well, rawls I think would be best...thats just my two cents...
I would like to know how it goes, good luck.
