So the backyard looked like this last week:
This week, after a mowing, two days later it looks like this:
These beasts are large diameter, sometimes with 12 or more heads. Our existing tools aren’t working.
Lee Valley sells this:
but 68$C is a tad high. That’s not more that a cheap pistol-style water nozzle with a Female hose thread. 10$C at Home Depot. 2.50$C for a Male Hose Thread to 3/8″? barb. Got some hydraulic tube from QM ($$$???)
The drill a slightly large hole in the ID of the pipe; as close as possible but still allowing insertion. Clean with 99% iso-p, apply JB Weld Original, wait 48 hours.
Testing shows the process works: https://youtu.be/_MaZi1MoIyQ
But:
- JB Weld has failed me! After 4 or 5 uses, started leaking, and very quickly tube came off nozzle. Will do something more rigid , likely better threads cut (use M10 for both tap & die, not M10 for one and M9 for the other (no matter the pitch, mixup like that makes for a non-functioning thread)
- need to make a plug for business end to restrict water to a fine high pressure stream. Tried the hammer-it-closed method, but needs something smaller.
- thinking get some plastic rod (bolts?) that can be threaded into the tip, with a hole drilled down the center of the drill (chop off bolt head); the hole can be sized by starting small and working upwards to find the optimum.
- This is a dirty wet job.
