I do appreciate the input, I'm just reluctant to tear it up and then all it will ever be is a heavy doorstop. I use this as an example...I have a Sears/Craftsman Electric Chain Saw. It unfortunately found a Hidden Nail driven into a branch I was cutting and broke the "Plastic " Drive gear. I took it apart found the broken gear went to Sears, they ordered me the part, and in the lifetime later that it took to get the part, I had to go out and buy another chain saw to finish cutting down the tree and cutting up the branches. In the time that passed now that Chain Saw is apart in a box somewhere, and I have long forgotten how it came apart. The tree is gone but the damage is done. I don't want another Chain Saw. I see a lot of people on YouTube using the HF jacks, if there was even remotely a problem, I think the issues would be quickly exposed. Especially when the jacks are being used on very popular channels, that could well afford Big Name Brand Jacks.
I was using the Racing Jack only as an example, I already have one and I'm well aware of its "Limitations". Again, it would be different if I had a clue about what I would be getting myself into. I have not found a video that shows the teardown of any "Walker Jack". And the folks over at Lazzar's which is local to me were nice on the phone, but they only sell parts. No joy with advice or a local place to just take the jack and get it fixed. This is after all Cailfornia, and Liability is king. So, I guess rather than add another Chain Saw to my collection, I'll just use what I have until HF has a sale. Thank You all again.
