phase II

For my phase II mod, by clamping each channel in a drill press, I was able to easily drift a tight-fitting clearance hole (for the cross-tube) right up against the underside of the channel's top. These tubes were then welded both @ their ends (where they come up against the inside of the channel wall) & also where they pass through the channels' inner walls. It takes all the cantilever (bending) load off the bolts (bolts don't like to bend), leaving them w/ simple shear loads, for which they are well oversize. This virtually eliminates all tendency for the channels to "tip" downward, as the load is applied, and keeps them in plane.

The WG should be find without it.

For the record, I'm fairly certain my 07 wg front end comes up first before the back end so I don't think it's a weight problem regarding your ultra.

I put the jack back to its original position for the Ultra. But without the support, the back end was still way lower than the front. Then I used my other Sears red jack without any mods and it worked good as usual.

I am definitely going to steal this one from you. Ive had that jack for years and am ashamed that my bitching has never evolved into something like this. thanks Vic
