I am curious about all things, sometimes to a fault. Not only do I like to know what makes something tick, one of my joys is figuring out how to fix, restore, or make it myself.
This blog is an extension of a webpage I built several years ago. I hope you enjoy reading about whatever project currently has my attention.
Although I am not a "sweets" person, I do enjoy conquering self-imposed challenges.
About every three years, my crabapple tree presents us with a bountiful supply of fruit, and I always consider making a jam or jelly with it as I snack on it while mowing the yard. The problem is that none of us eat jams or jellies.
So, for the sixth time, I will let the deer harvest our crop - they will get more out of than we will.
Saturday morning’s routine for number two son, after eating a biscuit at Bojangles’, includes hitting yard sales in search of kid movies on videotape. Although the breakfast part might include all or part of the family, usually it’s just him & his mom hitting the yard sales. But Kim was out of town the other weekend, and since Daniel wanted to sleep in, the morning belonged to Jared & me.
Even though the bulk of yard sales are a waste of time for what I would like to buy, I actually like visiting this bit of Americana because sometimes one will find the most unexpected bargains. That was certainly the case on this trip for me not once, but twice.
Several weeks ago I pulled my trusty cassette deck out of the closet to dub some music only to find the machine had gone belly-up. On the final stop of Jared & mine’s yardsaling excursion, I stumbled across an old Sparkomatic automotive-dash-mount receiver with cassette player. Not seeing a price, I asked the proprietor how much. He smirked and said, “A dollar; but you have to take the entire box.”
I understood because I had seen Kim do the same thing at her yard sales.
But as I was about the peel off a one, I noticed some folded up television antennas off to one side.
Although the two were bundled together for sale as one item, I could make out enough detail to decide one of the antennas probably picked up the UHF band. I immediately decided this was a bundle for me because I had recently outfitted our travel trailer with a new antenna for HD (UHF) television reception, and Kim was so thrilled with how well it worked in our driveway that she wanted to outfit the house with one in case cable TV went out during bad weather.
Since the devices appeared to be all but new, I figured this where the man was going to make up for his loss-leader. Nope – He asked a dollar for the bundle. Come to find out, all the stuff belonged to his in-laws who had moved (or had been moved) somewhere else, and a yard sale was the last step before the dumpster arrived.
Returning home, I found the box of goodies included a ready-to-go, self-contained stereo system that just needed to be plugged in to a regular house outlet. To my joy, both the tuner & cassette deck still worked fine, and I was able to listen to the tape pulled out earlier.
At some point, Daniel finally rolled out of bed, and interrupted my “Beer Bottle Polka” sing-along to ask if we could have grilled wings for the night’s supper. I immediately agreed because the meal was infinitely healthier than the pizza I had let the both of them buy for the previous day’s lunch.
Yum – grilled wings, baked fries, and squash on my side of the table.
Peeled cucumber & carrots on their side
They were both good sports & ate enough before we all left a pile of bones & vegetables behind.
Sunday found me unfolding & mounting the antennae on a temporary stand for identification. Various Internet sources agreed the top antenna was the best device for our inclement weather plan.
So the antenna was mounted on a 10-foot mast affixed to the chimney, and pointed toward where the bulk of our area’s TV transmitters are located.
The wall behind the den’s TV got a new 75-ohm antenna jack.
We now have a bunch of digital stations ready in case the TV’s running on generator and the cable goes out.
The “funny” thing is that if we could have pulled in the ABC affiliate, and METV, we would have strongly considered dumping cable altogether. But, by all reckoning, there appears to be a mountain in our way for our part of the city that precludes reception.
Stay tuned – I might find a TV tower at another yard sale; ya never know!
Although my Overlander came with a factory-installed, VHF antenna, I opted for a UHF bowtie antenna for our adventures because it was much smaller, and UHF stations were more common around here than VHF. When all of the TV stations were required to go digital, my Airstream was good to go because digital TV frequencies are in the UHF range.
But it appears that many stations are broadcasting their digital offerings with less power. My simple bowtie, on multiple outings, just was not up to the challenge. So Santa delivered a new, digital, RV antenna from PPL last Christmas.
The swap-out was relatively easy. The only issue was the mounting pole. The original was round, and the new one was square. Since I wanted to use the Overlander’s antenna rotator, my buddy Dan machined me an adapter.
What a difference! Up to this point, we have never been able to pick up local stations in the driveway because there is a mountain between us and the transmitters. But the new Winegard picked up all of them PLUS their sidebands PLUS Public TV. I was impressed.
We used the new antenna on last week’s trip to the beach to monitor the weather, and Kim was one happy camper.
While not quite as unobtrusive as the bowtie, it does fold up well.
While packing for the beach trip, I noticed the Airstream’s original TV antenna sitting quietly in the corner, and moved it into the Shop for a better look. It was bigger than I remembered.
Remembering that the same mountain that interferes with TV reception also hampers reception of Public Radio on my Shop’s, I wondered if that big ole 47 year-old antenna would work better than the existing, simple dipole thumb-tacked to the wall.
Since the Shop’s ceilings are 10-feet tall, the decision was made to mount the antenna to the ceiling. Rough cherry works well for FM applications.
The mount’s placement was chosen based on the unfolded-out size of the antenna. After screwing the mount to the ceiling, and then unfolding the potential super-station-getter, I found that the antenna’s 8-foot span would not be realized with the mount where it was.
Fortunately, it was easy enough to relocate the mount to the other side of the light.
Success - The results were worth considerably more than the effort. Although the antenna itself does not bother me, the wire does. I might, one day, run the wire through the attic space. If I end up going to that much effort, I will probably relocate the antenna there too while I am at it.
But the next project will probably be to connect an HD radio tuner to the Shop’s setup I have that did not work well in my truck. If it works well, I might just have to get another old Airstream antenna for the truck.
A month or two ago after winter was well underway, the outside temperature here in Alabama dropped into the lower teens for the first time. Although there were scattered reports of frozen pipes & power outages we fared okay. But a few nights later, the low temperature repeated itself, and I awoke to a cold house even though the thermostat was trying to get the furnace fired up. So I grabbed a flashlight & nut-driver, and headed out to take a look at the house’s main gas furnace while everyone else was still asleep.
Lots of steps are involved with getting a furnace to produce heat after the thermostat signals it is needed. In a nutshell, after enough time has elapsed since the last attempt at lighting the burners, a small fan designed to suck exhaust gas out the heat exchanger comes on. When a pressure switch senses the fan is on, a gas valve is opened, and an ignition coil sparks to light the gas. After another sensor verifies the burners are lit, a countdown timer for the recirculation fan is started to allow the heat exchanger to warm up a bit so that cold air is not blown out of the vents. After a short time the recirc fan spins up & distributes the heat to the ductwork.
After removing the service access panel, I was hoping to find a pile of ashes or some other form of smoking gun. No such luck – everything appeared to be in good order. Then, just as I was about to get up and get my voltmeter, there was a whirring sound followed by a click and a buzz. Moments later the recirc fan spun up. The furnace was back in action although I had done nothing to inspire its course of action.
I hate intermittent problems. It is much easier to find a broken part once it breaks and stays broke.
To cover all bases I checked the furnace’ User Manual and found that the furnace may not work in cold weather, and that I may need to take steps to keep my pipes from freezing.
In the meantime, though, the house warmed up, and stayed that way.After that, other than an occasional short
cycle, the furnace appeared to be working okay.
All was well until last week when Kim called me at the office to tell me the house
was cold again.I decided to cut out
early and see if something would stay broke until I could get home.
This time I decided to start tugging on wires in hopes of finding a bad
connection.Bingo! – A wire easily
pulled out of a factory-crimped connector on the recirc fan delay
timer/contactor.After crimping a new
connector on, the furnace happily whirred, clicked, and buzzed back to life.
Sadly, the repair only lasted for about six hours after I bragged about it on Facebook. In the middle of the next night, the furnace suddenly sounded like a clothes dryer full of tennis shoes. The recirc squirrel cage fan’s setscrews had decided to loosen up after 16 years and let the fan bounce around inside of its enclosure.
Fortunately, since the motor shaft was not chewed up, the fix appeared to be limited to re-torqueing the setscrews.
Well, that’s all that was physically needed. Before reinstalling the assembly, the wires were hooked up, and the house thermostat was set to turn on the fan only. No joy - there was no power in the wires.
Getting my voltmeter involved, the trail was found to end where this tale started - the recirc fan delay timer/contactor. When I pushed just right on the newly crimped connector, the fan spun up like it was supposed to. After verifying smooth operation, the fan assembly was reinstalled.
After popping the cover off the timer/contactor, I was about to look for a break in one of the foil traces on the printed circuit until I noticed how burned the contactor’s points were. It was obviously time to replace the whole thing.
But of course, since I needed it now, no one in town had one in stock, and a new one had to come in on the train from Pixley. Fortunately, with a little finagling, I was able to make the recirc fan spin 24-7. This made the rest of the furnace’s sensors & circuits happy enough to provide heat when requested until the replacement part arrived.
The new part was a Factory-approved replacement for the now obsolete original part, and was not physically identical to the old one. At first I thought some new/different connectors were going to be needed.
But the part ended up bolting & wiring up without incident. The fan and furnace now work when each is supposed to regardless of me pushing or pulling on connectors. Success has been declared since the furnace’s performance has been flawless for many days now.
In summary, there were two distinct failures, and one red herring. The first fault was with the recirc fan delay timer/contactor. Most likely, a tiny crack in a foil circuit trace developed, and was sensitive to temperature changes. Crimping on the new connector, AKA the red herring, flexed the board enough to “fix” the problem for a short time.
The second fault, and one that was new to me, was the fan set screws loosening up after that many years. But to have two disparate failures at the same time amazes me.
But my sweetie is now warm, and that makes everyone happy.
Within a few days of starting practice on my vintage trombone, I decided the slide was not moving as freely as it should. A good cleaning & lube seemed to be the best starting point to clear up the issue.
Although I was familiar with the generalities of brass instrument cleaning from my trumpet-playing days, YouTube was checked just to see if trombones required any sort of special attention. Sure enough, in addition to a cleaning snake, all videos reviewed followed up with the use of a Trombone Cleaning Rod. This tool is roughly three feet long, and has an eye at the end for threading on some sort of absorbent material. The inner & outer bores of the slide are then gently swabbed out with the rod.
The man behind the counter at the downtown music shop was able to sell me the cleaning snake and some slide lube. But he did not have a cleaning rod, and allowed that, as a guitar player, he had no insight into why one was not in stock. So I went home and with only the new snake & my mouthpiece brush from 30 years ago and cleaned what turned out to be a very dirty instrument.
While every music store on the Internet had one for sale, the shipping & handling charges were more the rod itself. My preference was to source the tool locally.
A week or so later, I stopped at a brass instrument repair shop, and was surprised to find they did not keep the cleaning rod in stock either. While the technician allowed that they had one in their shop, he said the only time it was used was when slides came in gooped with too much of a certain brand of slide cream. He inclined that, for routine cleaning, he thought a snake was sufficient as long as slide cream was used in accordance with directions.
I then posted a question on a trombone forum asking for insight on the tool’s use. Of course some people immediately replied “Get one & use it!” without elaboration. Other members recalled having one, but did not necessarily know where it was. Some people thought using the tool was worth the effort; others did not.
One guy, though, sent me a message expressing his belief that swabbing after brushing was important, and went on to explain how he had made the tool out of a 3/8-inch wood dowel. Since I already had woodworking tools, and a dowel was only 98₵, this appeared to be the way to go.
Sadly, it was not meant to be. The dowel was so close in size to the inner bore that I all but could not get a paper towel in. The helpful forum member’s trombone must have had a bigger bore because he said he used the modified dowel with patches of old sweat clothes.
Looking around the shop, I found an old brass welding rod. But milling a slot in the end was going to be an issue.
Then I remembered another fellow posting that he used the rod that came with his shotgun cleaning kit. Hey! I’ve got one of those!
While the aluminum rod was only slightly smaller than than the dowel, the screw-on plastic tip was notably smaller.
It worked out perfectly for holding on to a swatch of paper towel.
The inner bores both swabbed out clean.
The outer bores both had a tinge of green. Can’t say I’m surprised because the first time the ‘bone was washed, big cylindrically-shaped chucks of green/black slime washed out. And, I was careful to not push the snake too far into the end curve.
Out of curiosity, the outer slides were then swabbed with denatured alcohol to see if any additional coloring came out. Not enough came out that I think a solvent is needed on a routine basis.
Afterwards, the slide was lubed with a fantastically small amount of Superslick, and then spritzed with water.
The jury’s still out as the whether or not the swabbing helped. But I will most likely do it at least one more time to see if any more green comes out of the outer slide.
My shop’s compressed air supply is fed by a big ole 220 vac, Devilbiss compressor which Kim bought me in 1996. Although the cut-off switch was replaced about six years ago, I believe the compressor has been ON since the day I got it.
Yesterday found my shop OUT of compressed air. After less than five minutes of troubleshooting, I found a failed crimp-connector in the compressor motor wiring:
Although it is hard to see in the jittery image, I think the connector fatigued from vibration, and then arced & melted. Thankfully, the mating post was still useable.
After crimping & soldering a new connector on, I was back in business.
Since my going-in thought had been “motor replacement”, I was really happy that a simple connector replacement was all it took to get my shop air back online.
