amazingkevin Posted June 8, 2012 Report Share Posted June 8, 2012 I was haveing a problem with the blade tenstion not acting right . It was only acting right with a short tug to number 2 on the tenstion dial if the saw stopped in the down postion.If it stopeed in the up position there would be play and you'd have to pull up on the lower blade holding section to get rid of the slack.The problem being the bearing on the bottom of part number #10.A $ 44.00 piece as the bearing is not sold separate.So im going to jb weld the sleeve in the bearing to lock out the play .should last a long time ,my guess.I don't have that kind of money for the part and work is coming in.gotta do what i gotta do! Wish me luck! This is a type 1 scroll saw and i got the schematic from www.replacementparts.com Quote Link to comment Share on other sites More sharing options...
rjR Posted August 15, 2012 Report Share Posted August 15, 2012 Hi ALL & A.K. My 788 managed to strip the threads in the lower blade thumb screw. I drilled a hole to fit the insert in a grade 5 small bolt; rethreaded the piece of aluminum and ordered a new part. This is over a year ago now and I still have not put in the new part! The 7/16 head and a wrench work much better than arthritic hands anyway. I am not totally impressed with the saw. I have spent more on saw repair on the DeWalt 788 in 3 years for repair than I did total on my previous 2 Dremels.( One was the 3-1/2 inch blade prssed model -- I had paid $25 for it used and ran it almost 20 years, not bad. The other was sold when I moved and I had used it about 5 years with "NO ISSUES AT ALL!) I have used the DeWalt harder than those though! I did not cut hickory with them. -- Admittedly I have been cutting a bunch of name plates from hickory flooring scraps and it cuts hard! So My jury is still OUT on how good/bad the DW will be long run! As I do NOT DO extremely fine work I still prefer pin-end blades! I have been thinking of making a conversion on my saw. The next time I get the same aluminum failure(They should have used a decent steel ) I am going to try it. I will probably order the new $20 piece anyway. I also had one fuse blow and still have not figured that one out! It was on light work; I have used it much harder on other stuff and had no issues!
