hi --
not long ago i moved into a shared shop space which the owner built, and furnished with tools he bought from a tool collector buddy. he hasn't had the time to do any tuning or maintenance after building out the shop, and working.
now we're trying to get the 1980's unisaw and the DJ-20 8" jointer tuned + aligned. the other major floor tools are OK -- the planer and drill press are new, and the bandsaw is a used 18" jet in decent shape, with no problems so far.
we three shopmates are novices in tuning machinery, but we're trying. on the uni, we made new faces for the biesemeyer fence, aligned the miter slot to the blade, and aligned the top and fence to that -- all to within a couple of thousandths.
but still the cuts we get are ever so slightly wavy, though straight overall. so i took a good straightedge to the table, and it's noticeably dished within about 6" of either side of the blade path.
so we made a new insert, and tried new blades, but still the cuts are still slightly wavy. plus, the saw is screamy and loud -- seems louder than it should be.
the 8" DJ20 jointer has a few issues too: the outfeed table is worn at the cutter head area, and sags at the very end.
the jointer fence only holds itself square for a few cuts, and it drags on the infeed table. sometimes we can get good cuts, but it sure is a hassle, and unreliable to have to keep checking for square every few cuts. (it almost seems like the blade guard knocks into it, and kicks it out of square.)
so, my questions are:
-- are these things fixable, and how easily?
-- what to fix first, and how much should he expect to spend?
-- do we have to get the tables reground, and is that even worth the cost?
-- what can we do about the unstable jointer fence?
thanks in advance.
