Step 10: Epoxy in Place

Once the mortise is sized, squeeze in equal parts of your favorite epoxy.  I mixed them right inside the bottom of the mortise.

Insert the portafilter shaft into the handle and watch for squeeze-out.  Wipe off any excess epoxy with a paper towel.  If any epoxy gets on the wood, it's no biggie - the epoxy can be sanded off once it dries.

Let the epoxy set for the recommended amount of time and then some - I noticed that the large thermal mass of the portafilter significantly increased drying times by keeping temperatures low, and therefore slowing down the chemical reaction which dries the epoxy.
<p>Wow. Epoxy on. Okay. I was waiting for the &quot;fashion an end plug page,&quot; but that is certainly more simple. Looks nice! I will be doing this for one of my spare portafilters for my 1976 Gaggia Baby Primavera (US market version).</p>
very nice! I love wood tools!
Very cool! My favorite thing about having a wooden handle on my portafilter is the way the wood feels, it's just much nicer than a hunk of plastic. <br> <br>My guess from the choices you listed for the wood is persimmon, as far as I know it's the only one of the four with dark heartwood.
Wow, this is incredible! <br />Amazing work and a perfect Instructable. <br /> <br />Also, do you think I could use bamboo instead? <br /> <br />GM
Are you envisioning a hollow piece of natural bamboo? Sure - you'd just have to fill the end with something if you didn't want a hole in the end of your handle. You could also laminate sheets of bamboo plywood (plyboo) together to form a block, then carve that down to shape. I bet the exposed cellular like structure of the plyboo would look very cool.
