I have read a lot about homemade hangers, and saw a video of someone building his own glue-in anchors, but little else on topic. I'm interested as usual in the rudest possible means to an end. I'm climbing a small dome with a small waterfall and at a point 30' up have run into really miserable conditions (mud, junky rock, water). I overheard a caver, I think Yvonne Droms, mention her recent utilization of rebar pins in similar situations. I have used rebar aid in several caves already, but always on very small climbs as hand/footholds. In a situation where a climber needs to be attached to the anchor during an upward progression, is there any way to make rebar or any similar homemade anchor "safe"? I worry about attachment issues, and about impaling oneself during a potential slip or fall.
Otherwise, are there any suggestions for climbing quickly through a vertical slop-hole? Quickly because it's a wet, cold, windy spot and I'm a thermal sissy.
Thanks
