New here to rec.woodworking, love all the info. Thanks to all the
regulars that field all the question. Speaking of which...
I have a Powermatic 64A Contractor type table saw that I love. It has
served me well but always had a bit of a vibration problem. After
reading a few posts on TS tune ups I decided to buy a link belt.
Folks said that was the biggest leap in reducing vibration. After
reading a few more posts and site, turns out that PowerTwist (or any
other for that matter) doesn't make a link belt for a 64A. Something
about the slope of the V and its a 3/8 belt (which in and of itself is
not the problem, the way I understand it, the slope is the problem).
I read around an found one guy that replaced his stock 64a belt with a
3/8 PT belt and had success. Then another post on PT reviews on
amazon showed the only guy that didnt like the belt was one trying to
put it on a 64A. I then called the company and they said they dont
make a PT belt for a 64A, and didnt say one way or the other as to
whether I should try their 3/8 L series belt. the way I saw it it was
50/50 one good and one bad report. I went ahead and got it and here
is what I am seeing.
1. When everything is set up just right, the belt works pretty well,
and with much less vibration.
2. If I make any adjustment (like to blade height), it seems the belt
stretches and starts to rub on one of the bolts that holds the belt
cover on making a terrible racket. I cant quite get the belt short
enough to work at max and min blade height and not rub on the belt
gaurd mounting bolt without removing what looks to be an excessive
number of links. (However, I just read somewhere that I should be
removing something like 1 link for every 24 links in a belts that is
the same size as the stock belt.)
3. Ive tried removing links, but not sure how many is too many. I
imagine that if too many links are removed, belt tension will decrease
and/or start to slip since it is the weight of the motor that is
providing belt tension. At more weight is placed on the hinge point,
less is on the belt.
I guess my questions are:
1. Anyone have any info/experience with the 64A/PT link belt
2. Any I doing some obvious bone-head thing wrong.
thanks in advance to any and all that respond
