For a while now my my 4" dust extraction has been failing to clear the waste from a couple of my machines due to the machine ports being larger than my 4" ducting, so I figured the best bet would be to upgrade to 6" ducting.
First a heads up, I placed an order with http://www.dustspares.co.uk at the weekend & my order turned up yesterday, so not only very reasonable prices but also fairly quick delivery for such bulky items.
Not only that but they kindly threw in some freebies which are always welcome
There was also a mug but that had been pressed into service prior to taking the photo
I intend to run a similar set up to my existing 4" ducting as the flexibility it has given me has worked well, hopefully I can get on with this at the weekend so will post some photos up as I proceed.
