I've been reading a post made recently about a person wanting to glue a
chair back together that isn't exactly a tight fit. I'm not advocating this
as a fix for his chair but it was a reminder to me to make a post about this
Krazy Glue I just purchased recently (and if the chair isn't a prized
antique, maybe he could give this a shot).
The back story. My friend has broken printer at his business and the parts
are no longer available. Yes - did all the eBay, Craig List and local shops
things and just decided I could make the parts. After all, as a wood
hobbyist, I do own a few tools....
Problem is a simple broken cam with a shaft on the fuser that is made from
nylon. Found a 1/14" diameter x 3/8" thick nylon washer at Lowes that has a
3/8" hole. Since the cam needs a shaft about 1" long, I also found a 1-1/2"
long nylon connector that is slightly under 3/8" diameter. Not exactly a
tight fit and the shaft had more slop than I thought could be filled with
The cam part itself is tear-drop shaped and I knew I could shape that with a
Dremel. But first I needed to turn the shaft down to 1/4". In order to
hold this in my Midi Delta lathe, I would have to glue the nylon pieces
together before shaping the cam part so I could turn the shaft and make a
step cut near the cam.
Anyone ever try to glue nylon pieces together before and have them actually
bond - like permanently? Neither had I until I found this Krazy Glue -
Maximum Bond - No Run Gel, Ultra thick ( KG484) that has a list on it that
states it bonds ceramics, plastics, wood, porcelain, metal, leather, rubber
and vinyl - and is also gap filling on porous surfaces. Well we know that
Gorilla glue gap filling foam isn't good at all - so I'm doubtful of this
glue's claim of working any better.
Cleaned the mating parts with alcohol and applied a thin coat to both parts.
Slid the connector shaft into the nylon washer hole and let it set for about
10 minutes. Put the washer/shaft assy into my lathe chuck and started
turning the shaft - fully expecting this thing to go flying at any second.
Nylon turns about like hard maple - you need to apply some pressure and I
did. Took me about 10 mins of turning and checking the diameter dimension
and the shaft remained solidly attached. I would have bet against this
thing staying together under that kind of pressure.
This stuff works.... If the gap-filled bond can withstand the pressure of
being turned and not break loose, then providing a bearing surface to ride
on a metal shaft with little torque on it will never break it. Part worked
perfectly in the printer...end of story.
