Same thing you would do with a 5/16" 8-point: remove an NPT pipe thread plug from the base flange of your Briggs & Stratton model 5S 1 hp engine on your 1955 Toro Sportlawn mower.
Those T-handles are interesting, but I don't think they're Indestro. What sort of numbers are on them, and are there any other marks that might help identify them?
Both of these came out of a box of junk with tools that I've dated mostly before 1950 and some are clearly like 1910 1920ish.
Everything was very Rusty and I have some really oddball things that I've never seen before but I hope to kind of figure out what they are.
But there was a lot of rust. Some things are really seriously rust damaged. I've removed a lot of rust. I went and bought three more gallons of evapo rust.
Both are hollow so they could go over a longer bolt to get to a nut if needed. Not that I have a reason to believe they needed that for these.
The smaller one has no visible markings that I can see. The larger one has the following numbers stamped in the side
23635
So the smaller one conceivably they could have produced this by taking a steel pipe brazing the socket on one end brazing a cap on the other, running a hole through the cap and adding the t-handle. Of course it looks professionally manufactured. It's just that's how it looks.
The larger one looks like they started with a longer pipe. The pipe looks like it's tapered but it's not. It's 5/8 the whole way. Has the socket on the bottom then it looks like they drilled a hole for the t handle. And then it looks like they plugged the top with a small piece of steel rod that has a small hole drilled in it.
Oh goodness and I just realized that the larger 11/16 is a hex, not a four point. I had not looked at it in about 2 weeks.
I picked up a lot of stuff...
Every bit of it was just covered in rust. I will probably paint the jacks starting today. I've been trying to use the original colors if I can figure out what that would be. Fur example, matching the color on the Bergman metal shears was tricky. The closest I could find was patriotic blue. The P&C 1312 snips it looked like came in multiple colors but there was still sufficient paint on them that I could guess. Or at least get close, but neither had much pain at all. The threat I used for that was a clear at wine.
Put on those t handle nut drivers. I looked through some old catalogs and I could see things that were close but nothing really matched, especially on the 11/16 hex. It is so distinctive.
