If it makes you feel any better, when I order cutting wheels, I buy 100 at a time ;D
Ok... so another way to de-burr and "finish" your edges.... go back to that video where I show you how to sand a sinktube. Same premise.
Let's start fresh...
After I've taken the chrome off, I would draw out my design on graph paper and glue it to the sinnktube but for purposes of this class ;D , I'll draw my line directly on the tube (cause I want to show you something in a minute ;) )
Here's what it looks like after I'm done cutting.
Lot of burrs right? Both inside and outside.
Also... notice something here?
I DID NOT cut DIRECTLY on my line. The line is the ABSOLUTE. If something happens, say I take off too much during the 'de-burring' process... then there's no going back. Once it's gone... it's gone. So I leave me a bit of breathing room. The goal is to sand down to that line.
First thing I'm going to do is de-burr the inside of the tube with a sanding drum. Always at a 45 degree angle and NOT a 90 degree. The goal here is to remove the burrs, NOT get to the line (yet).
Next, with a large hand file laid down on my table, I'll LIGHTLY scrape the sinktube across it. I'm also rotating the sinktube between my fingers while I'm doing this. This ensures straight, even edges. I do this UNTIL I reach those lines. It doesn't take long... maybe a few minutes on each side.
Now, bust out your drill and attach your stop plug. Obviously, this shroud is too small put directly on the stop plug... so you'll make a "Shroud Supporter" <------- patent pending :D
-------------------------------------------------------------------------------------
reciepe:
One 12 inch 1.5 sinktube
3 8/32 X 1/4 screws
directions:
Cut 2 inches off of sink tube...save for later
Slice remaing 10 inches of sink tube directly down the middle.
insert 10 in peice inside 2 inch peice
drill and secure with the 3 8/32 screws.
Ta-dah!!!!
-------------------------------------------------------------------------------------
Ok... now attach you new shroud supporter to your stop plug. Slide your shroud onto said supporter.
With 600 grit sandpaper lightly wrapped around the shroud, pull the trigger and SLOWLY move the sandpaper back and forth over the tube. (if you do it too fast, you'll scratch horizontal lines in your sinktube)
Move up in succesion to 1500 grit. Do this till you reach the desired texture.
While the shroud is still on the supporter, I apply a little Mother's Mag or Brasso and then remove with a soft, clean rag.
And voila'!
So not only did we de-burr... we also smoothed and ROUNDED out these edged AND polished the shroud.
The rounded edges gives it a "milled" look. More professional and not sharp edges to cut your hands on!
Go figure!
