Hockey Jersey Display Case

Project:
Building a hockey jersey display case for our former youth pastor

Difficulty Level (Easy, Medium, Hard, Insane):
Medium

Process:
I was asked to build a jersey case for our former church's former youth pastor as a sign of appreciation of all the years of heart and love and time he has invested in this ministry. To me it was a fairly sentimental project because he has grown to be a close friend of mine and I know the passion he has for seeing teens grow in their love for Jesus.

There are many frames out there that are fairly straight forward, pretty simple and would probably do the job for most situations but I wanted this to be something of high value to reflect the quality and love he has invested in these teens.

The first thing I had to do after I got the custom-made jersey is take the measurements, cut and plane down some solid oak for the sides. The trim was too intricate to make so I had to go buy that at Kent but I couldn't believe how expensive that stuff was. It was like $40 for a short 6 foot piece.

After I got the trim I had to cut out a recess so I could mount it on the side frame and another recess for the glass to slide in. Because I wanted to make it removable I had to cut a slot into the top piece where the glass could be taken out in case he ever wanted to change the shirt or if the glass pane broke.

After squaring it up and gluing it all together I did a test fit with the shirt and the glass pane, then gave two nice coats of black paint. The last thing to do was to cut up a piece of wood for the back and one to hang up the shirt inside the case.

Pat, you are an incredible person, have such a passion for these teens and I admire that more than a little jersey frame could ever express!

Fixing Storm Door

Project:
Fixing the storm door window

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
I noticed that the window pane of our front storm door had slidden out of the aluminum frame and left a gap of about 1/4". I wasn't too concerned about the gap but the window could possibly shatter if too much pressure was put on it by its diagonal sliding so I figured I'd better fix it.

The process was pretty simple:
  1. take the window frame out of the door
  2. take the window frame apart
  3. slide the plastic trim back over the window
  4. slide that back into the aluminum trim
  5. install the trim back in the window
  6. install the window back in the frame
  7. all done

Fixing My Metal Lathe

Project:
Fixing my Emco Maximat V10 metal lathe

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
A few weeks ago I aquired (or should I say my wife "let" me aquire) a 1973 Emco Maximat V10 metal lathe. I knew there would be some things that required fixing and I had already fixed the Push Buttons For My Emco Maximat V10 Metal Lathe a few weeks earlier but two nights ago I was out in the shop doing some "just for the heck of it" turning (medium speed, cold rolled steel, 10 thou cut on 2 thou per revolution feed speed) and all of a sudden the lathe just stopped. It sounded like power was going to the motor (there was some humming) but the lathe had stopped turning. Of course I turned off the switch right away but I knew there was something wrong.

I started some troubleshooting and was able to turn the chuck by hand with no restriction so I knew it wasn't some locked up gear issue, and while turning the chuck by hand I could see the shaft in the motor housing turning freely so I knew the motor wasn't seized up.

After consulting with my Emco lathe peers at the Emco Lathe Yahoo Group I got a sneaking suspicion that the capacitor might be shot so I did some testing as per the video I found on youtube (link below in the Videos section) I concluded that the old capacitor was in fact deader than dead.

Fortunately, I did have a similar capacitor lying around in my spare electronics bin (I can't even remember where I got that one from, but I must have taken it off an old motor some time ago) so I put that one in and the lathe worked perfectly. The lathe started up full speed and worked as expected, except for the capacitor literally exploded about 5 minutes into my exercise with a big bang and a whole lot of smoke and everything. So I wondered if there was something wrong with the motor that causes the second capacitor to overload as well or if my "new" capacitor just didn't have the right rating. The original capacitor states "anlasskondensator" which translates into "starting capacitor" (I grew up in Switzerland so German was our official language). The only thing I could think of was that the original capacitor was rated at 330V whereas the new one was rated at only 220V. I figured that running on a 125V circuit the 220V would be sufficient, come to find out (and later confirm with my multimeter) that with A/C capacitors the voltage across the two terminals is actually about 1.6 times the rated capacity of the motor, which in my case turned out to be 267V, clearly too much for my "new" 220V capacitor.

After some more research I found out that there actually is a difference between a "Motor Running Capacitor" and a "Motor Start Capacitor" (I linked a great video from youtube that explains it well below in the Videos section). Even though the translation from german would make the "anlasskondensator" a "starting capacitor" it really should be translated as "running capacitor". Who knew?

My conclusion was that either:

1. The first "new" capacitor I used was actually a motor start capacitor instead of a motor run capacitor, or
2. The voltage rating of the first "new" capacitor was under-sized (the original was 330V and the first "new" one only 220V)

In the morning and after some calling around I actually found a local store (Wolsley) that sells parts for HVAC systems. Come to find out that these "RUNNING" capacitors are used all the time for larger motors such as A/C units and even washing machines.

I picked up the new capacitor for $27 bucks and plugged it into the lathe and there it was purring again like a 42 year old kitten. The chips were flying and the old capacitor (manufactured in October 1969) is now laying on my work bench awaiting to be taken apart with my son some other day.

Cost:

Savings:
At least $100 bucks over if I had to call an HVAC guy to come replace the capacitor

Conclusion:
Success. I hope it will last a little longer than the last "new" capacitor

Scrap Metal Storage Shelf

Project:
Building a shelf for all my scrap metal pieces

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
About 5 years ago I bought some 6" sonotubes, cut them to 2ft lengths and tied them together with some ratchet straps to store my scrap metal. However, over the years, the weight of the metal squished the cardboard sonotubes and the shelf started leaning forward. It was getting worse and worse to the point where you would just lightly bump the shelf and the scrap metal would slide out so I knew I'd need to re-visit my scrap metal storage solution.

I liked the concept of using sonotubes because they're fairly cheap but they're not strong enough to hold the weight of all the scrap metal so I figured I could weld a solid shelf out of 3/4" by 3/4" square metal tubes for the strength but then use sonotubes cut in half I could create 35 compartments into which I could organized all the different types of scrap metal to find it easier.

I cut up eighteen 30" pieces, welded them horizontally every 4" to create 7 shelves, cut the sonotubes in half and then to 2ft lengths. All I had to do is slide them into the shelf and put in the metal.

Tools:

Materials:
45' of 3/4" x 3/4" square tube (cut into 18-30" pieces)
7' of 1"x1/8" angle iron (cut into 4-20" pieces)
3-6" sonotubes, 12ft long (cut in half and then into 36-2ft pieces)

Cost:
$75.00 ($27 for square tube, $4 for angle iron, $36 for sonotubes)

Time:
3hrs

Savings:
Not sure what this would have cost

Conclusion:
Love it; now I can finally find my stuff!
