Dallas Makerspace Show and Tell - April 2017

Awesome! Got a link for the paper?

I got hitched on April the 8th! Leading up to it I took a class from @nausser915 to help me shake some rust off my soldering skills and learn to work with the finicky little “findings” that are the bottom part of the cuff link After that was squared away I then I turned out these cufflinks individually designed fore each groomsman. 4/5 are printed using the metaza from creative arts. Many many many thanks to @mreynolds for educating me on the metaza. The metaza prints beautifully on sterling silver apparently. My recommendation is to make sure you have a very well polished piece going into printing on it to minimize the amount of polishing you have to do after your’e done printing. The designed are fairly robust to rubbing though. The one for the best man, 2nd in the individual pictures, is hand punched and patinated. The lettering is 0’s and 1’s since we are both programmers and carries a hidden binary message. Hope you have your ascii tables handy.

Those are Amazing ~ I love how they are personalized for each groomsman!

Great job Austin! They came out beautifully. Also congrats, welcome to to old ball and chain gang

Ya, the paper can be found over here: https://www.etsy.com/listing/466125994/50-sheets-of-image-transfer-paper-for?ref=shop_home_active_2

He ships from France (although he apparently moved to Portugal recently) so it took about a month and half to actually get the paper in the mail. If you want to buy a couple sheets off me, I’d be down for that.

I made a dovetailed block on the Bridgeport. The block clamps onto the ways on my Taig microlathe and acts as a travel stop for the carriage/cross slide when I am using the dial indicator.

I bought an 8-flute 45 degree dovetail cutter from MSC, after a misfire with another cutter. The first cutter I bought specified the cutting width as 1/4". Much to my surprise, that was the tip to centerline distance, and it would only cut a dovetail 1/8" deep. Since I needed a 1/4" dovetail, I had to buy a 3/4" cutter.

Here is the part during machining. First I cut the U-gouge using a half-inch endmill, and then I made multiple edge passes with the dovetail cutter - each one at full Z depth but progressively further into the dovetail slot. @BobKarnaugh pointed out that the tiny tips of the cutter were likely fragile so I took a lot of very shallow passes - probably more conservatively than needed.

I subsequently ran an end mill along the inner top pointy edge of the dovetail to eliminate the sharp knife edge.

This is a simple part. I posted this here because it seemed to be an interesting curiosity while I was machining it - we don’t stock dovetail cutters so not too many people cut dovetails on the Bridgeport.

@John_Marlow that looks great. I haven’t had the opportunity to cut a dovetail, but will likely have the need in the future. Don’t be surprised if I hit you up for some advise. cheers!

Thanks to Beth ( @dryad2b ) for teaching the hand-built pottery class and glazing class. I am very happy with how my piece turned out.

I’m not done yet, but I’ve almost salvaged enough 18650 cells from laptop batteries to make a 500 Wh battery pack.

The cells in neat rows are ones that have been tested and verified to have at least 1800 mAh of capacity left. The box is full of cells that are still good, but are low capacity. I’m currently just shy of 80 cells above 1800 mAh, though I have a box with maybe another 40 cells that need to be tested and might yield something.

this is an embossing roll prototype I made for use with belt straps. I made a pair of softjaws for the Kurt vise to hold the rolls and to surface/size them I then center cut the hole and the keyway on the HAAS. I then take that over to my 4-axis at home (damn I wish we had one for the HAAS) to cut the pattern into the roll. The final product will be done in brass. ALUM is just what I had on hand today. If the leather sig ever gets a belt embosser I’d love to make some rolls for them. cheers!

This is so neat! Where do you get all the old batteries?

I got some of them off the freebie shelf, though most of those​ cells ended up being really old and low capacity. The rest are from IT at work. They had a handful they were going to recycle.

I am ready for teacher appreciation week. I also made a Texas pendant for a friend.

I was missing a speaker mount so I drew up the existing one and printed a matching one. Printed with PETG and spray painted. Thanks to @themitch22 for the printing help! (Side by side comparison below)

EDIT: Now posted on Thingiverse!

Honestly I can’t tell the original from the copy

The copy is the one with locknuts that DON’T use color-matched nylon inserts.

I mean, how tacky can you get? :smiley:

My wife wanted a wallet. I made her a wallet. Here’s an imgur album. :smiley:

Details:
Tandy “4-5 oz” shoulder (measured at just under 4 oz.). Dyed with Tandy Eco-Flow Waterstain (tan and brown). Punched with 4mm LC Diamond Hole Punch Pro, stitching is orange 0.8mm Ritza Tiger Thread. Edges burnished with cocobolo Dremel burnisher and beeswax.

Disclaimer. three dogs were frightened during the construction of this wallet (they hate when I hammer anything) but recovered nicely.

(edit: the dog is the same as my avatar, about a year older :smiley: )

Have you posted the design file somewhere (like thingiverse)? It looks great and would probably be really useful to lots of people.
