    I agree with the previous two posts about the pulse unit. I added it to my Lincoln when I bought the machine and have messed with it a couple times. I wouldn't miss it if it wasn't there.

    McMaster-Carr sells "welder coolant" for significantly less than the Miller coolant. I've had it in my Lincoln for roughly 2 years without issue. There's two versions (different glycol content and...

    I second that suggestion. In it's earlier versions, that book is also entitled "Analysis and Design of Airplane Structures". I think my copy is the 1949 "updated" version. Tons of information,...

    It helps tremendously if you drill a couple holes (~1/2") in the workpiece that intersect the kerf taken out by the hole saw for chip evacuation. Of course, this only works if you have a designated...

    It depends on the application. In tension, absolutely that's what you would do if starting with a clean sheet of paper. In shear, particularly single shear, running a hollow larger diameter bolt...

    McMaster-Carr shows aluminum coarse thread hex head cap screws.

    There's a lot of nice work in this thread! I'm originally from Nova and went to elementary school in Polk. I had no idea someone with your capabilities was in the area.

    Nice fridge!

    I would think 18 gauge is more than sufficient, particularly if you hem the edges. I have a similar vintage GE in my garage and they weren't shy with the steel in its construction. ...

    That was going to be my suggestion as well. Put the relevant data in its own sheet and export to a CSV.

    Same here. I'm guessing the minimum speed on your drill press is somewhere in the neighborhood of 500 RPM, way too fast for a 1-1/4" annular cutter.

    Related question: will a standard 3/4" end...

    I doubt it. Hole saws are generally twice (or more) the thickness of normal blade stock, and when I say "fine tooth", I mean something on the order of 10 TPI instead of the usual 6 TPI that most...

    Yes. I've TIG welded with regular ER70S2 rod. 309 stainless might be a better option for joining mild steel to tool steel. Attached is a special tool I made for torquing the pinion nut in a quick...

    I have a commercially made backing plate that bolts onto the extra holes in the back of a large diameter hole saw to stiffen it up. It does help reduce chatter when running it in the mill. I swear...

    Attached is a photo of a test bend of 1" x 0.065" ERW with Hossfeld tooling. No mandrel or filling of the tube. It measures 0.975" high and 0.950" wide in the bent area. 0.120" wall tube collapses...

    This is very dependent on the tooling involved. Hossfeld shows dies all the way down to 1.75" centerline radius for 7/8" OD tube, and recommends a minimum of 0.065" wall thickness, so it is...

    That sounds like it's going to be a custom piece. The closest thing I can think of is the Mittler Brothers "automotive" style punch & flare tool, which makes a 90 degree bend around the perimeter of...

    Well crap... looks like my photo links are no good anymore. I'll have to edit the original post and just attach them.

    At any rate, I invested in some feed along dies for square tubing and messed...

    Thanks to both of you for sharing.

    Ries, that looks like it has a few miles on it! I like the storage for the pins. That's a major difference vs. other benders, having a variety of pins to...

    No kidding on that part. I think the first thing I did messing with it was to bend some eyes.
