A new video for the new year. Vintage Buma boring machine running!

It looks similar to my boring bar made by Storm Manufacturing in Minneapolis Minnesota. The drive end is chain driven instead of gear driven like yours seems to be. The centering device looks to be similar. The fly cutter looks similar also. I've bored several engines with it. No idea what vintage; it's also old. It is nice to see the old tools still doing the jobs they were designed for! Congratulations for bringing one back to life.
