If you are talking about side to side movement in the blade holders with no tension, this is normal. The movement will go away when tension is applied. If you are talking about side to side movement with tension, then this can be corrected by adjusting the set screws in the blade holders so that the blade will be centered in the holders.
I noticed dgman (Dan) mentioned giving private scroll saw lessons. Does anyone else do this and what about insurance? The quote I was given for adding to my homeowners policy was prohibitive for me.
I use FD polar blades for 3d cutting as there is no need for reverse blades since the objects comes from the middle of the wood with no worry about fuzzies on the bottom.
My type 1 DW 788 is about 15 years old and needs a general overhaul that replaces worn parts and brings it to like new condition. The local Dewalt factory service center has qouted me a maximum price of $259 to perform this overhaul they call their GRC service. It could be less depending upon the actual parts replaced. Has anyone had this done and are you satisfied with the results? I am leary of spending half the price of a new one to fix my old saw although I would prefer my type 1 to a new type 2. The saw still runs great but is showing some signs of wear and needs a tune up. What do you think?
