Disc sander question about trueing up…
Hi everyone.Thanks for all the insightful responses in the “How long to leave clamps on glue-ups” thread.
I commonly make mitered frames out of 3″ wide oak.It is harder than heck with my tablesaw miter jig(similar to Gary Rogowski’s in the quicktime video) to get perfect joints off the saw.I try to clamp out the error by tightening the heck out of my steel band clamp.It works to some extent but they still aren’t perfect(once stained the mitered joint stands out,ideally it should disappear to some degree).
I’ve made a shooting jig complete with a Krenov style handplane I also made.I still can not get a perfect mitered joint.The plane rocks,imperceptively,and pre-empts getting a perfect fit.
I have decided to splurge a couple of hundred bucks on a disc grinder to true these miters up.It seems like a cinch from the magazine articles out there I have seen.I also like to experiment around with metal to some degree so I am sure I can use the disc grinder for other things also.
My questions are has anyone any experience using these grinders for such trueing up.Do they really work well in this application?Any suggestions or tips?
Also other than the obvious advantage of size does a 12″ disc grinder give better results than the more commonly available 6″ and 9″ ones.Obviously a 12″ disc turning at the same rpm motor speed will have greater speed at the edges of the disc than the smaller discs.Is that in certain circumstances advantageous.Thanks tons as always Roland.
