Drilling out Powertubes

CJOttawa · 08-26-2010, 07:30 PM

After the snapped powertube incident at the field last weekend, I was left using a tube that didn't have quite the flow rate of the previous tube.

Chain of events:

log on to M.CB
click through pump marker thread
see "Nelson Powertube and Spring dimensions" thread
see ID of #6 tube
look over at drill kit
figure out that a 3/16 bit will bore out a tube perfectly
...
PROFIT!

The 3/16" bit does indeed cut the #4 Lapco powertube quite nicely.

Next, I need to make sure there are no burrs to spawn cracks, specifically in the vent area.

Pics to follow shortly!

CJ,does a number 6 tube need to be cut down to fit into the redux or are they good to go out of the box?

Gotta cut most down as the dux utilizes short tubes just like CJ

Maybe a stupid question, but hand drill, drill press or milling machine?

Hand. Took the risk, basically self-aligning since there's already a hole drilled in the tube.

You know back in the day I was a 10 power tube user a year.

Why were you burning though them so much DSA? Just played a ton or what?

What are you at now? Changing it once in a while?

I've broken one since 2008. Back when I was auto trigger happy it was one a month.
