Howdy again,


I finished rebinding my guitar and have it ready for Z-Poxy fill.  I was using my newly purchased 12,000 RPM Hitachi 5" ROS to sand the epoxy off of scrap and left a couple of deep indentions where I didn't meet the surface dead on.  That experience has me thinking a sanding block won't be such a bad idea until I figure this little badger out.


What's the worst thing you ever did to a guitar with a ROS?  What do you do now, other than being extra carefull, to compensate?  Redoing the bindings was painful enough for me to consider asking here before I jump right in, hence the question.

Stuart-
You'll figure out the ROS with a bit more experience. For anything critical, a sanding block is probably a safer alternative- at least mistakes take longer to develop.
With a ROS, less pressure is better. Also, resist the temptation to use the edge of the disk if you are trying to get a level surface. Keep the paper clean- if there is even a small 'lump' stuck to the paper , your work will be covered in small circular scratches. A dust vacuum on the sander can help a lot with this.
If you want a really level surface (like guitar sides), a firm sanding block is the route to go, for most of us.

Cheers
John

Wow,


Think this thing's going back then.  I liked the way it fit in my hand and since it was roughly the same price as the Bosch and DeWalt models setting next to it, I assumed it was a "good" tool.  :-(


Is variable speed a necessity?  The only VS I've seen is a PC, at an extra $20.

  Wish Lowes carried Festool.  The Hitachi was spinning like mad prior to surface contact, which I guess was the biggest reason I was bumfounded.


Thanks, Todd.

I'm a new Festool ETS 125 owner and really like it. No airborn dust, even
without the vacuum they sell, and the papers are great. The salesman
recommended it over the dynabride when I asked.

The tool of choice in all the Panel Beater Shops I've worked in for fine sanding is the Festool line. They're a big ticket item but nothing beats them for quality of finish and durability. And believe me, sanders get abused in this line of work.

Just got back from town...traded up to a VS Dewalt.  It was the only VS they had in stock.  I wont get to try it out until tonight, but am looking forward to it.  I'm adding the Festool ETS 125 to my drool list.  Thanks, guys.


I take it the little dust collection bags aren't good enough and these things idealy should be connected to a shop vac, et al?

My PC, when you take off the plastic dust catcher, is designed to accept a small 1" or a standard 1 1/2' hose.  I hook it directly to my "Shop Vac" and get no airborne dust.  No adapter required.

I see what you mean about the backing pads being a little too mushy on this ROS.  Too bad I couldn't keep the pad from the other ROS...it was quite a bit sturdier.  There's a retailer in town who carries a selection of backing pads.  Hoping I'll get lucky now when their doors open on Monday.  The last time I looked at them, I didn't have a clue what I was looking for.  Much thanks for the tips.  I really appreciate it.
