Great photo Clive, I've got one those jacks it was in my HUP when I bought the HUP many years ago. Thing must weigh close to 200 LBS. As to the rest of what they were up to must have been a story. Cheers Phil ![]()

I noticed your comment about putting rubber between the blocks and hull to protect the paint. If you plan on having the carrier sit on the blocks for some time, I would replace the rubber with cotton waste. Over time and under pressure, the chemicals in the rubber can react with the paint and the paint will stick to the rubber when you get around to removing the blocking from under it.
Also, my Father in law worked for many years in the Transcona Railway Shops in Winnipeg. Whenever they had to jack up a steam locomotive (steam jacks in the day), they put a wad of cotton waste on the top of the jack to prevent any metal to metal slippage from happening. David |

Much like Richard, when we're working on the bigger stuff there isn't much that beats a big lump of wood. It spreads the load over a wide area and provides a good amount of friction to prevent slippage or movement.

I suppose everyone is a bit skittish about saying it as forum members are no doubt smarter than the average bear but under no circumstances should bricks or breeze blocks be used to support any vehicle at any time let alone something as heavy as a UC no matter how pressing the job.
Common sense cannot be relied upon as it is becoming less common in the population at large and so the compulsion to state what would be innate knowledge to most. Wooden blocks cannot be beaten for supporting a vehicle under most circumstances although axle stands are very good. Over the years I have found that the red-gum posts used in Australian suburban fences are an excellent source of material when cut to length and still can't help picking them up when I come across them.

X2 on the reccomendation against bricks. I have seen cinderblocks disintegrate under weight...

After reading through this posts, maybe I missed it but one should never, ever work on a vehicle that is supported on a jack or jackstands.
The blocks as described are the best, making sure that the load has been released from the jack and is bearing solely on the cribbing. Another area that is often ignored is the substrate. While maybe not quite so worrysome in your garage, jacking loads outdoors often has its own challenges. As was pointed out previous, make sure the fround you are working on is solid, preferably concrete. Soil, grass, gravel and even asphalt tend to give. I have seen all too often where guys will lift a load with a jack and toss a block under the frame "just in case". Many times the load hovering above the block. This is foolhardy because if the jack slips, rolls, get nudged etc the "safety" block may fail to catch the load on the way down, get split, dislodged or otherwise be pushed aside. The company I work for moves loads (mainly jack and slide) often in excess of 200-400t so I have a bit of an idea.... ![]() |

Have used both wood blocks and truck stands and to be honest prefer the stands for carriers, easier to set correctly etc I use 5T stands as a minimum ..... over 10T Armour go the wood blocks if you don't have specific hull frame stands. Most importantly however- do not support the weight on the floor plate. All stands/blocks should be on the corner's of the hull, where the side meets the floorplate, the weight bearing ability of the side plates is far better than the floorplate. I use a frame spot welded to this location to move hulls in the workshop, when the frame is cut off, it leaves a couple of weld dags that locate the stands nicely, and no slipping issue. Same locations should be used when jacking also FYI- sliding the jack under the floor is not the best way to go.

We don't normally have power connected to our suburban fences though in some parts that wouldn't be a bad idea. David
