Title: Turret Tip
Post by: kriswel on January 27, 2011, 05:32:38 pm: I don't know how many times I have built an amp and then went back to tweak thing only to find I need more turrets. I've never been patient enough to pull the board but I usually just jerry rig things PTP and a few zap straps... Now I usually add a few turrets in common spots from the get go.

Until today! I am sure I am not the first to discover this but I just drilled the holes I needed free hand with a cordless and crazy glued the turrets. Works like a charm.

I agree
J-B Weld would work

I'd also be worried about how well the glue holds with age.

one option would be to drill a hole and then screw or rivet a small tag strip to it (2 or 3 tags) assuming your chassis is deep enough.

Post by: LooseChange on February 11, 2011, 05:38:20 am: I have drilled a hole slightly smaller than the turret or eyelet (with an old used up drill bit) and forced it into the hole. Tight enough to stay in place. Thought about adding some glue after the soldering, but didn't.

Considering most parts that are soldered to the turret have fairly heavy wire attached, once everything is soldered in place it's really not going to go anywhere.

Here's my Turret Tip. I converted a watch cover press from Harbor Freight to flare my turrets. Not much throat, but if you do one side at a time it works great. It will also fit in a chassis pretty easy. You might have to take the board loose, but would not have to remove it. You have to take the watch press apart and rework the ram and bottom, but pretty easy for anyone with a drill press and a grinder (lathe makes it easy, but not really needed if you take your time). $13.00 http://www.harborfreight.com/catalogsearch/result?category=&q=watch+cover+press
