Garden 2018

It's been years since I tried a vegetable garden, but this year we have a better spot (the yard at the new house already had some raised planting beds built in a good location). Also,, Carter was interested too, which always helps motivate me. We planted lots of stuff - cucumbers, sweet peppers, hot peppers, tomatoes, summer squash, butternut squash, zucchini, green beans, sweet peas, potatoes, carrots, onions, broccoli, lettuce, honeydew melon, cantaloupe, and herbs. Whew! Things are starting to ripen and be ready for harvest, so the kitchen is full of fresh veggies these days.

Carter’s Room Makeover

Carter has been working on making over her room over the summer. We've already painted, and this corner is one of the other (many) things she's done. What I wanted to highlight is how much of this me made ourselves - the wood cookie side table was a project I mentioned a few posts ago, but Carter also made the two throw pillows on the chair, and the pouf-style ottoman in front of the chair. She's getting pretty handy! The photo at the bottom is another wood cookie side table we made for the living room, because we liked the one in her room so much.

Wood Cookie Side Table

Carter saw a side table at the store that she wanted to buy for her room, and I told her we could probably make one for next to nothing. And on top of saving the money, she'd have something her dad made with his own two hands - which someday might be important to her, or something. :) Anyway, here's the start of it. I cut the top today from an old downed log in the backyard, leveled it, sanded it, and put the first coat of polyurethane on it. It still needs several more coats, but it looks nice enough already that I wanted to get a photo out there for everyone to see.

Lixie Clock

A friend showed me a project online where somebody made an edge-lit acrylic clock inspired by Nixie tubes. Once I saw it, the seed was essentially embedded in my skull and I knew I was going to have to make one of my own. The acrylic panels were cut on my home-built CNC machine, the LEDs are neopixels driven by an Adafruit Trinket, and the case is walnut.

Nixie Tube Clock

I've been wanting to build a Nixie tube clock for many years now, but the high voltage required always scared me off. Recently I was looking online for a step-up power supply to try to finally build it, and found a site that sold a pre-built Nixie clock board for less than the parts would have cost me. So I ordered one, and built an enclosure for it. The outer enclosure is painted pine, and the 'face' is bubinga that I CNC cut around the Nixie tubes.

Metal Stock Drawers

Now that I'm starting to gather more materials for working with the metal lathe, I needed somewhere to store it. So I used some old plywood and pine to build this no-frills set of drawers to hold all my stock. I separated it by type (steel, aluminum, brass, etc.). I've still got a few empty drawers for the future.

Tailstock Die Holder

One thing I've been doing a lot of lately on the lathe is cutting threads. One trouble with cutting threads with a handheld die holder is keeping the die precisely perpendicular to the work - even something that looks perfect to the eyeball might be a degree or two off, which can be pretty noticeable when the surfaces don't make perfect contact when you screw them together. And it isn't like with wood, where you can force the joint a bit and crush everything together slightly to hide a slightly-off joint. So one solution to this problem is make a die holder that rides on the tailstock, to keep it both perfectly aligned with the axis of the lathe and perpendicular to the shaft being threaded. Over the past couple of weekends I've been making my old tailstock die holder, as you can see below. The tapered shaft on the left mounts in the tailstock, and the die holder (on the right) rides on the narrower half of the shaft (which isn't tapered). The narrow bar in the middle can be screwed into the body of the die holder if a little more torque is required. The recess at the end of the die holder is where the round dies are mounted when in use. The die holder was made from aluminum (to keep it light), and the rest of the parts are made of steel. This was my first experience turning steel. It went better than I expected, but I've got some reading to do to learn what cutting tool edge geometry works best for steel.

Burke #4 Milling Machine

In the back of my head I had been planning to buy a mill sometime next year to grow my burgeoning new hobby - that was the soonest I thought I could justify the expense to myself, and I wanted to give myself time to make sure I would enjoy this work before I spent the money to tool-up the metal shop. But recently, while chatting with a friend in the office about the fact that I am getting interested in metalwork, another coworker mentioned that his mother was trying to figure out what to do with her husband's old milling machine. Apparently he used to restore old outboard boat motors, and had a lightly-used milling machine. I bought it from her for far less that a brand-new (and less capable) mill would have cost me. I got a great machine, and she got a good chunk of her garage back - win-win! It's a Burke #4 horizontal mill, and is quite a beast. It was built in 1942 and is about 600 pounds of American-made cast iron. To get it home, we had to take it apart - but even then, those parts were probably at least a couple of hundred pounds apiece! The van was definitely riding low on the trip back.

Once I got it home, I took it apart further into assemblies I could work with. Then I scraped and sanded out the rust on any of the metal-to-metal sliding surfaces. As you can see in the photo below, there was a good amount of surface rust that needed to be removed - but there was no deeper pitting - which was great news. Once I got everything apart, cleaned up, and oiled I put it all back together in the room I actually wanted it to end up in - which you can see in the top photo. I got it all wired back up and powered it up to make sure it still worked, and it started right up. I've tested all of the axes, and everything is moving smoothly with minimal backlash. I have yet to try and make any chips with it, but now that I've handled every part of the machine I feel like I've got a very good understanding of how it works and what I can do with it.

Lathe Shelf

Originally I was keeping all of my cutters in a drawer in the toolbox below the bench. But that became kind of a pain, because I needed to root around in that drawer every time I wanted to try a new cutter. I needed to get them up at eye level, so I could more easily see what I have - especially while I'm a newbie and have no idea which cutter I should be using for any particular operation. :)

Fire Piston

A couple of weeks ago I made a fire piston on the lathe, but forgot to post about it. For those who haven't heard of a fire piston, they are a way to start a fire without matches using adiabatic compression. When you compress the piston quickly, the air inside heats up enough to ignite a piece of tinder held is a slight recess at the end of the piston. This one was tough because the tolerances had to be just right to prevent air from escaping when the piston was compressed - I actually ended up having to make the piston twice - on the first one, the o-ring didn't quite seal the chamber. For materials, the main part of the handle is aluminum, the handle end cap is brass, and the piston is brass. It can't be seen from the pictures, but the top cap of the piston can be unscrewed to reveal a small storage compartment in the piston - this can be used to store extra tinder (char cloth, specifically).
