Fire Department Jaws of Life? 2) Use a telescoping hydraulic cylinder (a.k.a. hydraulic ram jack) to push the two J-bolts against each other since they are both leaning in by the same amount. What I

The issue is not just removing the template. I could just cut it off. I need to KNOW that the template can be removed without to ensure that the tower base will go on without difficulty. We can't be
Why do you need 12" of bolts sticking up? If you don't, cutting them down to what you actually need will reduce some of the alignment issue, possible enough. -Steve K8LX The issue is not just removin

Instead of compromising the bolt or concrete, can you elongate the tower holes? You may also be able to shorten the bolts to minimize the portion that is out of location. John KK9A Got a nasty situat

There's no way I'd apply heat to the bolts over concern of weakening the bolts. I'd try to cut the template off with a reciprocating saw or a grinder. Why do you need 12" sticking out above the level

If it were me, I'd make some flat plate adapters from 1/4, 3/8ths, or 1/2" plate for the hydraulic jacks to push against. 1/4" should be strong enough. Pushing against the threads could be risky. The
Yes...enlarge the holes on the tower base. Die grinder with a roto-file bit(s). Will take some time but removing 1/8" of steel certainly won't weaken it enough to be a problem. chris KF7P Instead of
OK.... don't even THINK about using heat. Don't use a sledge.... too risky. Suck it up and do it right. Weld/rig up an exterior frame that can mount rigidly to the 4-6" of exposed concrete foundation
Paul, IMO the 1/8" .120 off center and the larger base hole with it's .060 clearance to the center line C/L I would use a die grinder and elongate the offending two base plate holes . Wayne W3EA Got
Use a cutting torch to segment your template; the kerf will provide enough clearance for the first piece to move that 1/8", and then the rest would have more room. Scribe match lines on either side b
Two suggestions based on my experience: 1. Protect the threads of your 1 7/8 inch rods by slipping a Schedule 80 PVC pipe over them. This pipe has a rated 1.936" inner diameter. This allows 1/32" inc

One other thing: I'm sure some folks worry that they might find, after plopping a self support tower down on *level* bottom nuts, that their pride and joy is not plumb. Not to worry, if the tower is
OK, but since Pirod's design spec, or instructions as it were, (and I love Pirod, believe me) is already faulty as you know, we are seeking after-the-fact solutions. First, there is no need for the b
Steve, no question...any amount of bolt height reduction does get me closer to the right distances...and that will make the base section easier to install. It's certainly one solution to consider, a
I should also mention that after working with several crane operators, they detest using their gear for any purpose other than to lift and place. For example, they will not use the end of the boom fo
