couple questions
Hey guys,
I've got a couple questions concerning my '81
1. does anyone have an Idea about how much the body of the '81 weighs, I'm doing an off frame on the car, it will have no interior, no front glass, no doors, no hood and no front or rear bumper covers.
2. I know this is a tough one, but is there anything that SHOULD be replaced while the body is off and interior is out that can't be done after it's back together. (I.E. the heater core)
3. even tougher one, does anyone have any experience with steel I-beam sizing, I want to put a beam in my garage that will span 23' and be capable of lifting around 1500# on a movable dolly set up.
thanks a bunch

Hi J,
I'll try the beam.
I'd suggest you determine where you will buy the piece of steel. Those suppliers often will have an engineer who will do the calculations to determine the load and thus the size of the beam you'll need.
If you can shorten the span from 23 feet just when you're actually doing lifting by being able to put 1 or 2 temporary posts under the beam, (closer to the lifting point), it will GREATLY reduce the size, weight, and cost, of the beam required.
A piece of steel 24 feet long and capable of supporting a 1500 lb POINT LOAD, (and not an evenly distributed load), will be pretty serious. It's weight alone will make it's installation difficult. I'd think it could easily weigh 500-600 pounds.
Regards,
Alan

thanks Alan, I'll keep that in mind, unfortunately, the place I'll likely get it is a scrap steel yard. I've been doing some research and it looks like a piece 12" high will span 24' and carry a point load of 2000#. or I could go 16" high and carry a 4000# load. next is to figure out how much it will cost.
thanks
thanks

Wow.. I've not had to do a tensile strength calculation in a long.. long time.. I wonder if there is a chart now on Google somewhere that will do the calculations for you. Like an I-beam tensile strength calculator...
Things that I know can't be replaced while the body is on.. Fuel and brake lines front to rear come to mind the most. Body mounts the obvious choice can be done with the body on but it isn't any fun...

I wouldn't even concider making that span with the beam just mounted at the ends. If you have a place to attach over head and your useing an I-Beam, there is no reason you couldn't use 1/2" or 5/8" all thread and wall mount brackets on the top side of the I-Beam to attach it to the ceiling/Roof beams. That will do a lot better job spreading the load and leave the bottom web of the beam for your trolly setup to run on.
