There are a number of problems with pinning - Shear pins in many situations - my backhoe auger, lawn mowers, outboard motors, etc are not required to handle frequent reversing loads, so a little slop
Kinetic Technologies has had them in stock when I've needed them & easy to do business with them. http://www.kineticllc.com/catalog.asp?prodid=672201&showprevnext=1 Grant KZ1W snip __________________
Some estimates, probably high side for rural LA - mini excavator plus operator $130/hr x 4hr dig + 1hr set cage = $650 concrete line pumper $130/hr x 3 = $390 plus offsite cleanup $200 laborer $25/hr
Tack weld the bolts together with #3 rebar when attached to the base so they don't move when set without the base to make concrete work easier. Grant KZ1W Can anyone refer me to a Dummy's guide to w
Flux core is the easiest, cheapest, and lightest way to weld in the field e.g. for fence posts in the pasture with a generator on the back of the ATV or Gator. The entry MIG setups also don't have a
Good point. Gave away my 240v 80# 225a buzzbox, weighs more than the entry MIGs, takes 240v 50a. The HF 70a unit (120v?) is probably ok for rebar tacks with 1/16" rods, but I think wouldn't do 2" sch
Interesting tidbit from some Googling: ".... reading a rebar should go something like this: The first symbol is a "production mill symbol." It is usually a letter. The examples would be an "NN" for N
Ground the anchor bolts to the main rebar cage with several short pieces of rebar, tied tightly. You might consider tack welding if you have followed the recent thread on that! My HDX589 bolts were t
Several times my PTO auger became an unplanned screw anchor, it could instantly screw all the way down into wet/damp CA adobe. The grade 5 3/8" bolt shear pin also sheared. With no reverse and no way
I like the Tyco plastic circular connector line, a 9 pin version, from Mouser http://www.mouser.com/catalog/catalogusd/646/1576.pdf . I use the gold pins, good for 13 amps. Buy the pin extractor and
I host a ISP in a rural area (unlicensed 802.11 service to neighbors) on a dedicated 10' stick of R25 with 1500' elevation and 20 to 40 mile sight line. I get free 8Mbit bidirectional service and as
I used two resonant elevated radials, about 18" above the sand and 5' from high tide at TX5D for 20 ->10. That worked super well. Stay within 1/4WL of the water and it will work. IMO no direct connec
LMR500, but why?? A solid center conductor BCCAl will fail if repeatedly coiled. http://www.timesmicrowave.com/downloads/products/LMR-500.pdf Grant KZ1W I am looking for a 50 ohm somewhat rigid cable
I have the same question for a tower in design. My structural engineering skill is dubious, but nothing I've designed and built has failed, so caveat emptor! There are some handy on-line calculators
I called Philly directly with some questions about really old Phillystran and they were very helpful. Grant KZ1W On 2/25/2014 6:37 PM, Tom Nicholson wrote: I'm going to be using Phillystran Cable .22
I talked to the factory this month about old (pre 1991) Phylli. I've also taken some of the 5/8" dia apart since I have about 1800 feet of it and would like to use it on a Rohn 65G project. The facto
Conrad, Not sure what you have locally, probably something similar in metric or still Imperial in the construction trades - IMO, regular sch40 PVC conduit is the best choice for moisture, critter and
A another choice is the W6NL scratch build "110mph Moxon". Particularly if your site is challenged with wind or ice. K6KR and I together built two and I acquired one for a 2x2 stack from K7ZSD. It co

It's been a while since mine was apart, but I don't see how water can get to the pot. IRRC it's on top under the cast Al top bell, so it would take a hole in that bell to get water to it. Also, could
