CAD > Laser Cutter > Wood Lathe = ???

So we started off with a CAD file, this one is made in Graphite.

Then we used a laser cutter to cut it out onto 3mm MDF.

That’s not me in the pic but it’s pretty much the same object that I turned on the lathe today. Here’s a few things I learn’t that hopefully I won’t forget by writing them down.

  1. Cut diagonals into the end of the job to identify the centre point and give the spindle something to bite into.
  2. Mount into lathe.
  3. Adjust tool rest so it sits slightly above the centre.
  4. Adjust lathe speed.
  • Slow Speed – Used for balancing and larger jobs.
  • Fast Speed – Used for small jobs.

Technique is all about finding the right cutting angle as it varies between tools.

Sanding / Finishing

We worked our way down from 80 grit to 400 grit sandpaper then polished with the saw dust we created.

The final product.

Glenrock #3

Today I had my first crash on my bike. I was riding at Glenrock, Newcastle once again. After doing a few of the jumps on the short track I thought I’d make my way onto the larger trail and do the big loop. I came up to a blind corner with a bit of speed, I turned left to find myself going down a fairly steep gradient. The track was rutted and damp from the previous rain. I attempted to slow down by using my brakes however my wheels clogged up with mud and just started sliding. I managed to hold on for a bit but eventually slid into a rut which threw my balance off to the left. In a split second I went headfirst into some shrubs then WHACK hit my head/helmet on what I think was the ground. This caused me to do a front flip which was kind of smooth as I had my camel pack cushioning my back. I eventually came to a stop to find my shoe was about 2m up the hill.

Geocache: Balls and All

This epic cache started last week with Ben, Noor, Ross and I being locked out of AMF at 10pm. Rather than going home I fired up my new HTC Touch Pro with this nifty Geocaching App and we started off with a nearby cache, after that relatively quick find we thought we’d try a multi cache. We managed to get all 4 waypoints but stuffed up with the last one and after crossing the river twice we gave up.

Today, armed with more time, sunshine and a footy we headed out in search of the satisfaction of finding this metal container full of goodness. Below are some pics of the final find.
