Gib adjustment on jointers

Post by seeaxe » Mon Jun 11, 2012 5:14 pm

Anyone got one of these (generic taiwanese 6 inch jointer) AND still have the owners manual?

I bought this at the weekend 2/h and the outfeed table is both misaligned and loose.

I understand the gib screws need adjusting and tightening but as all websites with info on the process have apocalyptic warnings of eternal doom if you get it wrong, I thought I would try and find a manual first. Crazy I know, but I thought I would try.

This particular model is about 10 years old, of taiwanese extraction and was marketed by a wide range of resellers

I got hold of the manufacturers/resellers and they were delightfully speedy in assisting - by sending me the manual for what they sell now, which isnt the same model. They probably sold hundreds of these but didn't keep any manuals....

So I am hoping someone in loofierland has a guide book and wouldnt mind scanning the one or two pages on gib adjustment and pm-ing me.

Yours in hope.

I'll wait until the weekend then I am reverting to type and getting stuck in with my straightedge and 10mm spanner..... :twisted:

Hey Richard.

Hmmm... Distributors should keep files of manuals for most, if not all, machines they have sold for servicing purposes. Sadly I guess that may not always be the case.

The trouble is without knowing the model exactly, they may not guess right - as you have experienced. Does this still have a model number (preferable) and/or brand at least ? The more info on it the better. I can't see much from the little image.

Hey Richard,

Sorry but a manual won't help you at all mate cause they put far less effort into knocking those up in some version of chinglish than they do constructing the machines, so much so that its probably a good thing you can't find one. :D

My advise is to use the basics and for that you only need a decent sort of straightedge....the knives however can be a bit more of a challenge .. The link below has a description of the standard process most wood mechanist would use to set the gibs...don't agree with his point re; the orientation of indents in the gib plates, it works that way on quite a few machines but not all cause some are 'not' relieved at all and the marks are a result of impressions left by the gib screws which 'does' create a high point that will bind. If you follow that bit of advise on the wrong machine it will likely cause more of a problem....best bet...just pay attention and document via photo if you ever pull the things apart.

Here's a reasonably good page on jointer basics Richard, certainly read worthy but again I disagree with some of the article such as gib screw adjustment alone not being able to bring tables that are out of alignment into coplanar. Its been my experience that most times they can do just that unless there is other issues such as excessive wear of the gib plate or ways. If that's the case then shimming would be the only way to sort it out because eventually, in order for the gib screws to do the job alone, the top one would need to be so tight that you can no longer adjust the table....it just a matter of getting the balance right most times 'and' pulling things apart now and then to clean out the crud and get a smear of fresh lube onto the dove tails....one thing is for sure, even if all is in order with the machine, should the lube have dried out in the ways from just sitting around then adjusting the gib screws is going to be an exercise in frustration. This is because instead of sliding smoothly, the dovetails will grab and tilting the tables a little as they move....Oh and just like tuning a guitar, always set the tables when the adjuster is under load...i.e to eliminate lash, adjust 'up' to the straightedge so the adjuster carries the full weight of its table.
