600mm+ wide sander?
hi all
I need a sander that gives me at least 600mm+ sanding width, I need it to sand timber panel and end grain chopping boards, I only have single phase and it seems the only sanding machine available to perform such task are;
- stroke sander
- Oscillating sander
- wide drum sander
I have never used any of them, think the stroke sander is a great machine but it requires a bit of technique and its quite open and seems to be a dusty operation. I am not sure about the finish by the open end oscillating sander and I have been warned about the over heating of the wide drum sander (also been told the guys who has over heating problem used it as a thicknesser, however I am not convinced, to rub a timber with a piece of sand paper require a bit of strength anyway)
that leaves me with monstrous 3 phase wide belt sander.
should I invest in getting 3 phase power to my house? ( 400v box is 3-4m from the boundary of my property) or I should be fine with the wide drum sander? the wide drum sander from carbatec is $3000, I managed to source a new 7.5hp wide belt sander for $6000, but to get 3 phase it will be at least another $3000+
or I should be fine with the wide drum sander such as this one?
Carba-Tec® 635mm Wide Drum Sander - Twin Drum : CARBA-TEC
its an one man workshop, I wont have other machines turned on when sanding except the 3hp dust extractor, not sure if my current extractor can handle the dust generated though, its only a 2300cfm machine.

Hi Albert
I've used both a stroke sander and a wide belt sander (the Jet 16-32)
If you use either sander as a thicknesser and try to take off a lot of material, both sanders will heat up the work piece.
of the two, the Jet was much much easier to use
the stroke sander takes a degree of finese that took me quite a while to develop. However, once you master the technique I believe it's a bit more versatile that a drum sander -- it can level glued up frames where a drum sander will leave cross grain scratches in either the stiles or the rails.
Dust collection is on a stroke sander needs lots and lots of suck. Where single phase might happily run the sander, you might need a 3 phase DC setup.
Having used the Jet 16-32 and been very happy with its performance, I'd be inclined in your situation to look seriously at the Jet 22-44
lastly, a stroke sander has a fairly large foot print, which could be significant in a one man shopregards from Alberta, Canada

A stroke sander will do the job, , but the footprint is large and they are not that user friendly, the drum sander will do what you need and has better dust extraction.
With a coarse belt the drum will remove glue etc, but changing the drum sander belt/strip, is slower and requires attention to the tension, however you will not get major sanding hollows, or belt gauges with the drum sander, and may be better for a single man workshop.

hi albert
we have a carba-tec 600mm twin drum sander at our local mens shed and we use 60/80 grit, if you have your feed table at minum speed it will do a very nice job, but make sure you scrape all the glue of your timber other wise you will be changing the belts frequently.
regards john.
ps not sure what is causing the red lines, help,

hi Ian
thanks for that, very useful information, i probably will give up he stoke sander as its too large for m6 workshop. especially if i am going to get a combo machine with 2400mm rip capacity...
thanks vk4. yes the footprint is an issue for me...
thanks john, yeah i think i will get that drum sander, if i find the motor is underpowered i will just put sand paper on one drum only

To thickness sand a 600mm surface, you only need a 400mm open-ended drum sander. Mine's 400mm, but I can pass a piece through in one direction to do 400mm, then turn the piece around and pass it through again to sand the remainder. That way, it can handle up to 800mm wide timber.
It's this one, from Hare & Forbes: https://www.machineryhouse.com.au/L110

It has the advantage of a very small footprint for small workshops. Great for thicknessing - I use it in lieu of a 'real' thicknesser.... Steve

Just an update.
After using the 16inch thicknesser on my Robland NX410 Pro for a week, I am completely sold on the quality Euro machine.
comparing my stand alone made in China 15inch thicknesser, the Robland thicknesser produce much better result, the noise is less and there are less moving parts
This has led me to re think about the sander, I am going to visit a joinery shop to see how a proper wide belt sander works (Griggio sander)
