Hi Guys,

Any advice on how to remove the internal nodes on Bamboo that has been split?

 

I need to do this in order to use the Bamboo for an irrigation system so the inside needs to be "Smoothed" out so that the water will flow freely.

 

I've looked online and only found the one you tube video that said to use a hammer and while this does remove some of the node it still leaves an amount that causes the water to not flow freely.

 

TIA  

Get a dowel if you can. Its like a rounded chisel, or a rounded plane, and a far second, because of dust and clamp requirements, you could also try a circular steel brush or circular stone grinder of suitable circumference.

Perhaps using a large hole bit used to drill holes for doors.

or

getting a heavy duty piece of steel pipe......have your village handyman/welder cut the tip half off and sharpen the remainder......use with a hammer to knock out the nodes

 

Thais are pretty good at solving problems like these.......especially if you live in a village.

Good luck

An angle grinder, with an ordinary disc, should do the job, but the heat will leave burn marks in the wood, follow up with a  sanding discs, you would want the corse disc, By-Hin-Geeiar-Cut-Mie-Yap in Thai, and if you have a lot, you may need 2-3 discs, they are only 25-30 each ,a sanding disc would do the  whole job  but a bit on the slow side. 

Thanks for the replies, this has done the trick.

 

 

Also tried an angle grinder with a thick grinding disc but this took longer than the hammer and it did leave burn marks.

 

Not perfect but as a friend once said "You're not building a piano"

PS I think the suggestions of a sharpened bit of pipe and a dowel would also have done the job

Update, knocked this up out of an old bit of pipe and it worked really well.
