Sharpie Posted January 10, 2007 Share Posted January 10, 2007 I'm making up a dummy block just for testing and assumed that the weight of the car on the stock jack would be supported on the underside of the car rather than the thin blade part which, runs down the side of the car. I offered up my dummy and it fits fine, allows the blade to be inserted into the gap and allows the sides of the block to reach the underside of the car and take the weight. (I have not actually tried it with any weight) However, I took the stock jack and offered it up and it seem the weight of the car is actually supported on the blade rather then the underside of the car. On the stock jack, the cut out for the blade is not deep enough for the top of the jack to actually reach the car. Should I make the cut out on my block shallower than the current cut out which, I cut to allow the whole blade, and some more SO it would not bend the blade ? I don't want to punch any holes in the underside of the car if the blade should take all the weight. Note: The car will be up on 4 axel stands and have a trolley jack too. here are some photo's Quote Link to comment Share on other sites More sharing options...
TLicense Posted January 10, 2007 Share Posted January 10, 2007 I would measure it and make your cut only a mm or so deeper, then it won't be a problem either way. Quote Link to comment Share on other sites More sharing options...
michael Posted January 10, 2007 Share Posted January 10, 2007 Is that pine? A bit soft for supporting a car perhaps? Quote Link to comment Share on other sites More sharing options...

Ark Posted January 10, 2007 Share Posted January 10, 2007 Is that pine? A bit soft for supporting a car perhaps? Not necessarily...it depends on how long the car is going to be on the stands. Remember the garages use rubber pads...just a little bit softer. A bit of give might be a good thing actually - add some cushioning. Or am I talking crap again?

JohnK Posted January 10, 2007 Share Posted January 10, 2007 I made something similar from aluminium and thick rubber. The weight sits on the sil and underside, not on the thin part. Works fine and I had it sat on them for weeks when I did my manual conversion. Quote Link to comment Share on other sites More sharing options...
merckx Posted January 10, 2007 Share Posted January 10, 2007 I wondered about this . I would make the little blocks so the weight is supported evenly between the vertical and horizontal sections of the chassis. This will prevent them buckling slightly and neither part would be damaged as weight is distributed . I'm sure if the vertical section is a a consistent depth in the four locations Quote Link to comment Share on other sites More sharing options...
Bob Posted January 10, 2007 Share Posted January 10, 2007 I made some out of 4x2 timber - just make sure you cut the groove against the grain. As JohnK said, the car is supported by either side of the 'blade' bit. I use 1 block for my trolley jack, and 2 for the axle stands. The car was on the axle stands for a month or so and never had any problems. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 11, 2007 Share Posted January 11, 2007 I wouldn't put stands under the sills anyway. Use something more substantial like the front x member or the inner ends of the rear suspension arms. Quote Link to comment Share on other sites More sharing options...
Bob Posted January 11, 2007 Share Posted January 11, 2007 Doesn't the Toyota owners book show the sills as stand points though? Quote Link to comment Share on other sites More sharing options...
