UnMaker 2.0 – The Largest Dead Blow Hammer

A few years back, Brandon made a giant wooden mallet from a piece of butcher block counter top that was laying around the space. This was a 9pm, make-it-right-now sort of project. He’d repurposed a chair leg as the handle, but it was a bit too short and bent, making the mallet awkward to use. We dubbed this bludgeoning device “The UnMaker”, and used to “unmake” things that needed unmade. Eventually the handle failed and the head was lost.

Fast forward to August 2018 – Eric and Kevin were cleaning out the shed a bit and decided to build a new UnMaker. We turned up some maple planks for a head and handle and started piecing things together. The head was going to weigh about 15 pounds. About that time, we noticed that we had “just enough” material to build a hammer that matched the proportions of the bright orange Dead Blow (shot-filled) hammer hanging on the pegboard across the shop, and an idea was born.

After some quick math, we ended up hollowing out several layers of the head using a router, and purchasing 4 packs of 6000 steel BBs from Walmart to fill the void. It turns out that lead shot, while ideal for this application, is expensive and difficult to find. We ended up with about a 60% fill, and a total head weight of 34 pounds.

Ben helped out with the handle design (using a taper and a retaining pin) to make it replaceable in the future, and Eric put a coat of orange paint on the finished product.

The result speaks for itself. You don’t so much swing the UnMaker 2.0 as you do lift and drop it. My form in the video below is sub-par, based on our later experiments.

In an ironic twist, this giant utility knife hit Hackaday shortly after we finished up our hammer.

TOG Dublin Maker BBQ

On Sunday 22nd July, from 14:00-18:00, we’ll be holding a BBQ in the space as a bit of a wind-down following Dublin Maker 2018.

Maker is always a hectic day, but great fun too. It’s great for us to have a lazy, wind-down afternoon in the space. Drop in and say hello. We’ll have some food and drinks on the go, and a bit of banter too. Hope to see you there. We’ll be sure to give you a tour of the space if you’ve never been in to see us before.

Maker Faire Kansas City 2018

Once again, members of the Omaha Maker Group participated in the Kansas City Maker Faire. Due to a general lack of interest, we forwent an “official” OMG booth entirely this year, focusing instead on the Power Racing Series. Garrick and the Tesla coil crew had quite the show, though, and even got a photo of their setup in the Make Magazine article.

After the Faire on Saturday night, most of the gang went to the new Hammerspace, the local Makerspace which is “like a gym for people who like to make things. WITH ROBOTS!  AND LASERS! AND 3D PRINTERS!”.  Their new location is HUGE, and it sounds like things are going really well.

We did a lot of things “right” this year, staying downtown (the new Home2 is an easy walk to Union Station, as long as you’re not carrying a cooler), skipping the booth (so everyone gets to hang out together and no one is “stuck” for their shift) and not waiting 3 hours for “pretty good” barbecue (Sorry guys!).

Race Results

Our amazing Power Wheels crew scored a FIRST PLACE in Moxie for the Amazon Box Car this weekend in KC!! With strong driving and an almost unbreakable car, we came home with a 3rd-place overall for the weekend! WOW! Great job to everyone who had a hand in it!

The BMW car had a very respectable finish, too. Again, great driving and a great design proved their worth – 90 seconds to change a tire? That’s amazing! The body, unfortunately, did not fare too well – it stayed behind in KC, destined for the trash bin. But the car is home and is a ready platform to build on our successes.

Thanks again to everyone for a great weekend.
