Thread: these 150mm ports

Yep - no problems - CI cuts like butter under a thin kerf cutting wheel in an angle grinder.
Cut a 170 x 170 mm square hole and around the port and patch it with a piece of sheet metal with a 160 mm hole and a female PVC fitting
Better still would be a bell mouth hood exit.

how about the std metal cases that band saws, table saws have...how are they enlarged..

Same way.

Before you reinvent the egg, have a read through the forum as there is heaps on this topic.

EG
Improving machine cabinet dust ports.

Look at how John Samuel modified all his machines.
Making 150mm DC ports for workshop machines

I used a jig saw with metal cutting blade to cut a 6" hole in the base of my cabinet saw - worked well.

The other useful tool for making a holes in metal is a "nibbler". I used a Makita nibbler to cut a 150 mm hole in a combination machine. The steel was 4mm thick but the nibbler had no problems cutting through it.

Remember you con't need to be able to cut a round hole. Its easier to cut a square one and then patch it with some lighter gauge material.

further to this....where do I buy 150mm PVC flanges etc? ie as in a flange that will screw/fix to the body work and have a connection (?) for hose to fit.

Saw in Bunnies the other day in kitchen section concertinaed aluminium 150mm tubing that expands to 3 meters its designed for oven hot air extraction but I figured it should work for dust as well.... thoughts?

The quickest and most expensive way is to purchase the 150 mm version of this floor flange

But Bunnings don't sell them and I would never buy any PVC pipe or fittings from them
You will need to go to a Specialist PVC pipe supplier (not a Plumbing Supplier) to find then .

I get my stuff from this mob
Pipe Online - Retic Fittings , Plumbing Fittings, Reticulation Supplies supplied Australia wide
Some folks say that even with shipping to the eastern states they are cheaper than what they can buy them for on the east coast.

If you can find the 150mm version f the Floor flange make sure you are sitting down when they tell you the price.
Even then they are not ideal which is why its better to make your own.

You should have a read of this thread (Improving machine cabinet dust ports) all the way through and you will get lots of ideas about home made flanges also how to make quick connect and disconnect 150 mm hose fittings.
Posts #81 and 111 shows a home made flanges from PVC pipe.
Bear in mind that most efficient flange is the Bell Mouth Hood and there are posts in that thread that show how to make these.

At a minimum you can always make a basic flange using a square piece of MDF and cut a hole in the middle the same size as teh OD for 150mm ducting and glue in a piece of 150 mm PVC pipe.

That is indeed quite a good price.

As posted elsewhere had a win (well I thought so in Adelaide this week) had been thinking around this dust collection and what I could afford, the limited power available etc etc and had settled on a Leda DC1500T then bingo just before buying brand new, up popped a S/H on gumtree less than half price...so grabbed it.

now the 2x4" ports are already off getting ready to make a 6". If I replace top bag with pleated filter will it it make a worthwhile difference, what if I coonect it to a cyclone somehow will that also help. Yes I'll be changing over to 6"" outlets on all power tools where possible. My 'dreams do come true' thread has been attacked by SHMBO (sometimes) and I now have supposedly 4m x 7+meters. I hope to run drill press, RAS, thickneser, jointer down one length and my 9 year old unopened table saw TSC10-HB in the middle.Q regarding table saw, I think this is a cabinet ...if so can I change the frame so free standing and ease/improve dust collection underneath....

so many questions, only one frayed head... good night sweet dreams
