To hold things in place while I drill them, I found that a layer of
JETT SETT (p.310 in Rio Grande Tools Catalog) in a shallow plastic
container that your pieces will fit flat into, works great. You don’t
have to buy the kit. You can buy the plastic tea kettle at CVS, and
look around the $1 store, or thrift stores for shallower plastic
containers to melt it in; they eventually become distorted, because
you heat the JETT SETT to make it pliable, and the plastic teakettle
does it very quickly, so you have to turn it on and off sometimes to
get it thoroughly melted, especially when just starting. Just
throwing the JETTSETT in the water didn’t really work for me.
Then you implant the metal, about 1/2 mm down into the JETTSETT, and
let it cool completely. Then I brace the box with my hands under the
drill press, and it holds the metal parts for drilling perfectly. I
stop when the drill gets clogged to clean it off, and also use a bur
wax before I start it up again. Put the power on high (are you
wearing glasses?) before drilling.
Low speeds don’t work at all. After, throw the plastic case with the
metal in it upside down back into the teakettle, and by turning on
and off, the JETT SETT will gradually turn soft, and you can easily
remove the pieces.
Just leave the JETT SETT in the plastic cases for next time.
A tried and true method, I’m happy that every time I do it now.
perfect results. There’s also a training video at Rio Grande on the
P. S. Rio GRande also has a two pages on riveting equipment, and
probably a video on those, too (p. 134- tools catalog)
