Are the Greenie bench tubes larger in diameter than the later Shopsmith tubes? I just purchased a set of replacement bench tubes off eBay and the diameter is to small. I measured the Greenie diameter and came up with 1-7/8" and the ones I got off ebay were 1-3/4". Did I actually get bench tubes...or were they way tubes? Length of the new tubes seems Ok at 52-3/4".

My October 1955 Greenie has 1-7/8" bench tubes and 1-3/4" way tubes.
How come you needed replacements bench tubes?

Hi,
There have indeed been threads identifying the bigger-diameter bench tubes on the oldest Mark V's. Also, the Lift Assist is offered in two p/n's to accommodate this difference.

My tubes are solid rust and I was being lazy. I guess I'll just have to clean the rust off and paint them.

Mine too. Being equally as lazy, I decided to give 'em an electolysis bath. Here's the early stage of what the bathtub looks like. I'll line it with poly sheet, pour in some of my magic broth, connect my battery charger and then go to sleep. When I wake up, they'll be squeaky clean and ready for scotchbite.
Have you seen Nick's video on how he gets rid of the rust on the bench tubes the lazy mans way? He uses a potato in a PVC pipe filled with H2O. I just tried to find the video but couldn't. I'll look again or if someone knows where it is, post the link.

Now the idea of using PVC is interesting. Maybe an outer pvc pipe and an inner to reduce volumn and fill with Evapo-rust and let soak. Sounds like a lazy man solution.
Nick's potato video (http://www.youtube.com/watch?v=qYgnHDB3VNI). I personally think the "potato" method is a not worth the effort for heavy rust.
MickyD, could you briefly explain your electrolysis bath?

Check out this website. It is the one I cut my teeth on. I've been using electrolysis for a couple months to restore cast iron cookware and now, it's going to be my best friend for ShopSmith restoration.
