Old metal screwdrivers
 
I recently picked up some old almost all metal screwdrivers. The ones
with just the wood inserts in the handles. The wood is very weathered.
What type of treatment can I use to stabilize the wood in the handle?
Thanks,
CP

Just surface weathered w/ a few cracks or is it "punky"???

It depends on how pretty you want it to be. I have one screwdriver
built like that, and a meat cleaver that is similar. I used ordinary
hardware-store epoxy on both. They're probably stronger than they were
when new, but they're not the prettiest things in my drawer.

I'd probably do nothing (other than keep them out of the weather :) )
than perhaps sand a little and oil, then.

As Ed says, you can fill but unless the cracking is so bad they're
actually going to fail or they're uncomfortable, a little checking won't
make any significant difference on the longevity and I tend to prefer
that stuff that's old with "character" keep that as much as can without
being anal about "reproduction" or "antique" status.

I've got a flat Stanley driver that just big enough to be more of a really
well made prybar that I like (got it from an old timer for a token amount,
then he died). It's old enough to be wood with a blue paint job. I use my
tools, so it's not going on a display case or anything, but what might be
a good way to seal it up and protect it just a bit so the paint lasts a
bit longer?

What did folks do back in the day, if anything with these tools to keep
them in good shape?

The plastic stuff we have is maintenance free, so "screwdriver PM day"
doesn't really happen around here too often.

You might look up Boiled Linseed Oil / Crazy glue on the internet. It is quick, but may not last too many years.

We just did "flat Stanley" for the youngest grandson... :)

On a painted handle, I'd probably only add a wipe-on varnish after
cleaning...

Mostly nothing other than keep dry. I've several wood-handled
screwdrivers from grandfather that've been here on the farm since the
'20s or maybe even were original ten years prior to that, I don't know.
I remember using them from the time I was first big enough to get into

Actually, just using them regularly likely kept them in good condition.
Human skin oils are also effective 'drying oils' for finishing wood.

Anybody know if there was a preferred type of wood used for screwdriver
handles?

Recently Went to the guitar center with a friend who picked up some drum
sticks. I noticed they proudly state "hickory" on the good ones, so I
asked the sales guy what's special about hickory and mentioned it's what
good hammer handles are made from. He said will gracefully break and never
shatter into splinters. Guess that's a common desired factor in striking
tools and drum sticks.

For good ones, it was often Rosewood early-on, then Walnut, often. The
"Perfect Pattern Handle" was the first successful commercial version.

I've found the plastic in X-lite tends to get oxide or is attacked with
a mold. I have sets of them that get gray and fuzzy. Not flaky.

I put them in a basket in my RF sweeping cem tank and some Simple green
or like. In a day they are bright and nice again.

I haven't seen the effect on anything but the x-lite brand. I suspect
a different plastic is used and that makes the difference.

Clean them with soap and water, then let them dry. Then clean them
with mineral spirits. Each cleans different dirts/oils from them.

Then give them a treatment with one of the following wipe-on tung oil
varnishes: Waterlox Satin (my favorite), Watco, or (since it is about
all that stores carry any more, cringe) Minwax Wipe-On Poly (did I
really type that out loud?) sigh

I said to remove them so you can finish all sides and truly seal them.
2 coats will do it. More than that may cause the handles to get
slippery when your palms are wet. You want a sealer rather than a
thick film finish.

Rosewood is one strange material. Had a small coupon of it on my keychain

I've got a couple Stanleys that do that too. Both have triangular
shaped handles, kinda translucent charcoal color. I used my
finger nail to scrape most of it off (big tough nails). Figured it
had something to do with being kept in the basement and too much
humidity at times...

All of them. I have always owned Xcelite tools since being in the TV
repair business in the 1960s, and the computer biz in the 70s through
1997.

All of their plastic handles, upon exposure to high humidity and warm
temps develop that white haze of fungus. It has to be one of the
plasticizers they use.

No biggy. A little abrasive cleaner like fine steel wool brings them
right back to shape.

never seen this- have used a ton of them, old and new. Is it real mold or
some sort of haze, like superglue on plastic haze? It's not super humid or
hot all the time in Chicago though.

Not sure about xcelite, but lots of screwdriver handles are acetate. No
plasticizers in there. Do you have something that off-gasses around your
tools?

Nah... it's specific to Xcelite tools. I've been experiencing this since
the 1960s, and I have lots of other brands that don't do it.

This is Florida. 90% humidity, and temps in the 90s, ALL SUMMER LONG.

And it is a fungus, but an innocuous one, apparently. No stink, but

I believe that is silica - same stuff sand and glass is made of.

Cedar tends to have a fair amount of it too. One of the things that

Early craftsman drivers had the same problem. I believe they were
either tenite or acetate based plastic (made from cellulose)

You will find the "deterioration" is caused by ultraviolet exposure

Kwik-Poly. http://kwikpolyllc.com/ It's a water thin two part epoxy.
Scuff the wood with some 220 or so to open the pores and brush on a few
coats, it will absorb into the wood. Let it cure for a few hours and
lightly scuff it to even out the finish. The wood will last a LONG time.

This stuff works great to seal fuel tanks as well as a host of other things.

That might be the case with the Craftsman handles. I can assure you it
never was the case with my Xcelite tools, because they were only used
indoors, and kept in the dark all the time they were not in the active
position on a fastener. (tool roll, inside a closed briefcase-style
toolkit.

If _never_ handled, they keep for years without any discoloration. Once
touched, if used frequently, the blush never appears. Store one in the
dark for a few months without use, and it's almost white all over.

Besides, we looked at some under the microscope... just out of curiosity.
It's clearly a fungal growth.

I still suspect they are either Tenite or Acetate - modified celulose
- whether it is ultraviolet/ozone oxidation or actual fungus

or like. In a day they are bright and nice again.

I haven't seen the effect on anything but the x-lite brand. I suspect
a different plastic is used and that makes the difference.

Is this a problem with the black or the fruit colored handles?


Early craftsman drivers had the same problem. I believe they were
either tenite or acetate based plastic (made from cellulose)


Did you say cellulose?

All of them. I have always owned Xcelite tools since being in the TV
repair business in the 1960s, and the computer biz in the 70s through
1997.

All of their plastic handles, upon exposure to high humidity and warm
temps develop that white haze of fungus. It has to be one of the
plasticizers they use.

No biggy. A little abrasive cleaner like fine steel wool brings them
right back to shape.

I agree..same here.

Silicon is the element. Si
Silica is the oxide form of Silicon or SiO2

I believe that is silica - same stuff sand and glass is made of.

Cedar tends to have a fair amount of it too. One of the things that
makes both a little tricky to glue.

Anybody know if there was a preferred type of wood used for screwdriver
handles?

For good ones, it was often Rosewood early-on, then Walnut, often. The
"Perfect Pattern Handle" was the first successful commercial version.

Rosewood is one strange material. Had a small coupon of it on my keychain
for years, it was outlasting the other metal junk attached next to it.

I used it, SiGe GaAs and another in diodes. :-)

Hah! That, too, in my former life as a digital circuit designer.

Now, I use elemental Si as a 'heat' additive to pyrotechnic compositions!
Military apps use quite a bit of it. G

Bamboo is also full of silicon and is thus hard on tooling.


I've heard stories that you can get sparks cutting large pieces of
rosewood. How do all these minerals even get into the wood in the first
place? It doesn't seem like silica/sand get be absorbed by plants and end
up in the wood.

They're formed internally from the dissolved minerals in the water taken
in and then crystalize.

Ash are another altho again it's "silca" and "silicates", various oxides
of silicon the element.

That's exactly how it gets in there. The whole process is a bit
mysterious, but the idea is that silica is absorbed as silicic acid
and silica is deposited on the cell walls. Some plants absorb more
than others. Grasses, like bamboo, absorb a lot. FWIW, rosewood is
related to the sweet pea. I don't know if that has anything to do with
its silica absorption, but it's a curious aside.
