Week of Making 2017!

Week of Making

The National Week of Making starts June 16th and runs through the 22nd this year, and we’re opening our doors on Tuesday, June 20th, 2017 for you to come check out Milwaukee Makerspace.

Okay, to be fair, we open our doors nearly every Tuesday night at 7pm for anyone in the community to come check out what we do. We have a meeting every week and love to have guests come and talk about the project they’re working on.

(BTW, we will not be open on Tuesday, July 4th, 2017 so if you’re planning another Tuesday night visit, that’s a good night to skip.)

Milwaukee Vice!

This is our Post Vice at the Makerspace. It is a specialized type of vice used by blacksmiths. Designed to handle the abuse of clamping something very hot and heavy and allowing to to beat on it with a hammer. These are not really mass produced anymore, so when you outfit a forge you typically end up buying a used vice. Since these were so well built they basically last forever. Ours is somewhere around 100 to 150 years old.

Most of the dents you see were there when I bought the vice 4 years ago. However, the slices running near the top, left face are new damage, and go considerably deeper than the surrounding dents. I was concerned about the concentration of stress at those points and the potential for cracking the jaws. It was time for refurbishment and repair.

In this photo, 2 recent dents that were caused by someone missing with a heavy hammer. And you can see where the jaws of the vice have cracked away. The vice is constructed using some kind of iron, but due to the age, we’re not exactly sure what. The jaws style of construction indicates that they were forged, not cast. This is a good thing, it suggests they could be either steel (exact carbon content would be unknown) or wrought iron. It means it should be possible to weld new steel onto them! This is what we’re going to try to do.

We don’t know exactly what alloying elements are mixed into the iron, so it could weld smooth, or it could blow bubbles and burn up under the torch! No way to tell until you try, which is nerve wracking when the object in question is an antique. There are things you can do to tilt the odds in your favor… Continue reading

Spindles of Wood

“Spindles of Wood” is not the name of the latest album from some obscure Icelandic emo band! Instead they are actually the front wheel spindles for our No-weld PPPRS vehicle. (You probably remember the frame from last time.)

While most teams in the Power Racing Series just buy pre-made spindles and weld them in place, our “No-weld” spindles were built using wood, glue some staples/screws, and use some 5/8″ bolts to attach to the car, and for the wheels to attach to.

We’ve still got to get the whole steering thing worked out, but we’re on our way! (Things are moving a bit slower than we had hoped, so we might debut this thing at Detroit in July instead of Kansas City in June, but we’ll see how it goes.)

Because 3D Printing…

3D Lock

Sometimes you see amusing things at the space. Take for instance, this lock on the bathroom stall. The black piece is actually 3D printed. Yes, someone took the time to measure, and model, and 3D print a rectangular bar to fix the bathroom stall door lock.

Never mind that a piece of wood, or plastic, or metal could have probably done the job in much less time, sometimes you just need to 3D print a replacement part for a bathroom stall door and you bust out the 3D printer and in a matter of hours you’ve got the part you need!
