unisaw + DJ20 jointer issues: ideas?
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 the shop.
now we’re trying to get the 1980’s unisaw and the DJ-20 8″ jointer tuned + aligned. the other 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.
on the uni, we rebuilt the biesemeyer fence faces, aligned the miter slot to the blade, and aligned the top and fence — all to within a couple of thousands. but 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 6″ of either side of the blade path.
so we made a new insert, and put on some 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″ jointer has 2 issues: the outfeed table is worn at the cutter head area, and sags at the very end.
so the questions are:
what should we do first, and how much should he expect to spend? are these things likely fixable, and how easily? do we have to get the tables reground, and is that worth the cost?
thanks in advance.
cheers,
philip

Sounds like a bad blade on the Unisaw, the DJ-20's table is adjustable so you can try to fudge the sag out. It is also pretty easy to replace the table on that jointer.
Pardon my spelling,

Make sure that your next project is beyond your skill and requires tools you don't have. You won't regret it.
Flip,
the saw is screamy and loud. seems louder than it should be
I had the same problem you describe with your unisaw with my powermatic 66.
First check to make sure the arbor pulley is tight. A loose pulley on the shaft will make a rumbling noise. Turns out my pulley was loose, but it had been for some time and wore both the pulley and arbor. I had to replace the pulley, arbor, and bearings. It is quiet as a church mouse now. I would suspect your noise is one or a combination of those 3 things, however, as mike pointed out, try changing your blade first. That is also a possible source of the noise, but if it is loud and obnoxious like the noise my saw made, it's probably not the blade.

The beauty of a parallelogram jointer is it's fully adjustable unlike a dovetailed jointer which can be shimmed on one plane. You should be able to adjust it to where it works fine.

Hey flip I really doubt the slight dish in the top is your problem,I own a delta /rockwell1948 ,a deltaRT31 a 2002 uni/ &abrand new contcactors saw all of which I have bought from or through my good freind who has been a/ (the in Vancouver B.C) delta mobile repare services for 20years or more . and it sounds like your bearings are shot which should be about $30 if you can replace them your self ,but if nota repair man is about $40.00 anhour.if your arbour is shot then it is likelly anouther $130-$150. good luck but ,the cost is deffinentlly worth it

Dan,
Oh really? He was talking about making a duplicating machine to make them himself. I guess it was easier and more cost-efficient to have you make them for him. Are you template-routing the gunstocks?Chris @ flairwoodworks

actually we are getting together tomorrow to talk about the design the duplicator I have one ,but we are going to make one with a boaring head. the ones I 'm working on now are from the 1880 s so its all by hand after roughing out on the bandsaw ,and forming on the lathe ,I do all my boring while the stock is still a rectange .the winchester is a blank which DAve bought and only needs the final hand shaping &finishing .don,t let DAve fool you he,s an amazing machine guy but when it comes to wood he,s not the guy,plus if I don,t stay on his butt the duplicator won,t happen /have you seen his shop? he has projects from the 1970,s LOL.

I will say hi for you , I notice you said you would like to go to the states with your imaginary 5 ton and all that cash on another page, why!!!! if you know Dave he deals with alot more then delta or even wood machines .anyways take care and let the wood chips fly!

Dan,
While I may be able to get good deals through Dave, it never really occurred to me when I wrote that. I've been eying one of their 17" bandsaws which are less than $1000. You're right. I should talk to Dave and see what he can do.
I'm a woodworker who likes a colourful shop. Some Makita, some Delta, some Steel City, some Dewalt, some Bosch, etc.Chris @ flairwoodworks
