Re: [MBZ] Weekend Report (long now short and deep)

The regulations are 1.5m depth for excavations, which is a guideline, 
insofar that if someone is kneeling in a1.5m trench they are gonna get 
buried if a side collapses.
Yes I do get into deep holes but test the sides first to determine that 
they are stable and dry, if in any doubt I'll bench it.

on a "soft" surface, or place a piece of rubber sheet under them so they

at the time (a 1970 250C) was well below the maximum load.

That's when I got rid of them.

The jack has a very slight leak that's been present for some years.  The lack 
of hydraulic fluid was a cumulative thing that I had just never addressed.  I 
haven't seen any leakage since I refilled it, so I'll continue to use it with 
diligence.  That means inspecting it before each use.

Again, I am very careful when working under a car and usually have multiple 
means of supporting it in place.  I have no intention of being squished under 
my car.

When you're excavating a trench, do you ever get down in it without shoring?  
I'll bet not.  My rule - never get in a trench or hole deeper than my waist.

Dunno, dodgy ramps and a flakey jack, sounds a bit dodgy.

Subject: [MBZ] Weekend Report (long)



All in all a very productive weekend with the S500. Saturday started with the 
construction of a set of ramps.
I couldn't bear to part with $40 or $50 for the metal Harbor Freight models, so 
I went to Lowe's and bought a couple of 2x10x12s and made my own by cutting 
progressively longer pieces that I stacked on top of each other to form a ramp. 
A pass on the end of each board with a 45 degree angle, plenty of glue and deck 
screws between each layer and a pair of very functional ramps were now ready 
for my car.
Next I took on my Craftsman floor jack that has been acting up for some time. The "speed 
lift" function hasn't been working, and it has been lifting less and less as time goes on. I 
had done some research as far as adjustments and repairs, but these yielded no results. I suspect I 
might have been low on fluid, but for the life of me I couldn't find a place to fill it. Finally, 
after a very thorough inspection, I found a plastic plug in the side of the hydraulic cylinder. I 
pried the plug out and realized that this was the fill port. After I put almost 6 ounces of 
hydraulic fluid in it, it was once again lifting as it had in the past. I still don't have the 
"speed lift" function, but I'll compromise in order to have full lifting capabilities 
again.
