RESTORING AN EGG-BEATER DRILL A GOODELL-PRATT DRILL Some
months ago I picked-up this little Goodell-Pratt egg-beater drill at
the flea market for cheap because it is in poor shape with the cap
for the handle missing. It is worn and dirty, unloved and in need of
some TLC. I've disassembled the drill into it's major parts...
I haven't decided if I will remove the handle and it's ferrell...probably so, as I'm going to re-paint the frame and bake the paint job. There are some other issues with this particular drill... At
the right of the picture are the jaws and springs of the chuck; the
springs are shot....I will have to search thru my collection of
springs to see if I have something to replace them.. Looking at the screws/bolts, the bolt with the knurled knob is what held the crank on the large gear....I am not sure if this is correct and will have look up a catalog to see if I can determine if it needs to be replaced. If so I will have to find an appropriate bolt... Near
the bolts you can see the triangular shaped retainer that holds the
main gear on...this part is badly worn and I will probably need to
make a new piece... In
this picture is the plastic cap that was
substituted for a lost or broken cap...I am going to have to make a
cap from appropriate wood... The
next issue is the paint scheme; I don't know if the gold paint that
is on the large gear is right...all the drills I have seen have been
painted red....more research. Well, my research led me to Rose's Antique Tools; they have a Goodell-Pratt Catalog #16 available on-line. I'm not sure of the Model # of my drill, but it looks very similar to a Model #4 1/2 in the catalog. Since the #4 1/2 is the only drill similar to mine ... only one knob, 3/16 chuck...I will go with that assumption. Okay... #1. I found a spring in my stash of the proper diameter. #2. The knurled bolt is not correct... #3. The retainer is hardened steel so I'll make a new one from O1 tool steel. #4. The wooden cap will be Rosewood; the only problem is the internal threads...we'll see about that. #5. The catalog indicates that the large gear was nickel plated...I'll be painting mine red!
THE RESTORATION I
found a spring in my stash of springs that I can cut three new
springs for the chuck. I have no clue what it went to originally. Cut
to size and fitted to the jaws.... As you can see the chuck parts have been cleaned up already....using a soft wire brush on my bench grinder. I'm going to have to wait till I can get a piece of rosewood to make the cap, everything I have would waste too much wood to make a small cap from it. I've
made a new retaining tab from a small piece of 01 tool steel.... Working
on the paint job....the frame ready to spray. Painting
the main gear... The
result is a somewhat better looking drill... I
finally got aroumd to making a cap for the drill...it isn't Rosewood
and I wasn't able to thread it so I just glued it on.
