Mick's 70 Lowlight

So got to work on the heads today. Had a few hiccups along the way. My Chinese Dremel's flexible extension decided to melt itself into a tangled mess. It felt a bit hot, then there was smoke and then it kinda tangled itself into a knot and stalled the motor. So I went out and bought a proper Dremel extension with a mini chuck. I'm hoping this one will last a bit longer, not that I'm complaining about the old one, I've had it a few years and it's done a fair bit of work.

Next drama was that I didn't tighten the new mini chuck enough and it proceeded to throw my carbide burr across the workshop. I heard it hit the wall of the garage. After pulling everything apart and searching for nearly an hour I gave up and went out and bought another burr. Typically I could not buy exactly the same burr. but the one I got was close enough.

So with the dramas sorted I managed to get all the exhaust ports done and one of the inlets. To do the inlets I decided to remove the guides and smooth out the guide boss. I also took the opportunity to shorten the guides by 5mm and taper the ends. This opens up the port area a fair bit as the stock guide pretty much sits in the port and obstructs it. I blended the roof a little and smoothed around the guide boss but didn't really do too much else. Will finish the other three some time during the week.
