  • installing blade

    I bought a almost new Dewalt 788 #1 last night about 11Pm, and thought I would see how easy blade changing was. I put in a couple and no real problems. Then I removed the blade and lossened the bottom Knob Assy Clamp (#47 on parts list )all the way until it stopped just so I could see the slot the blade goes in clearly. Then I tried putting in a blade and could not budge old #47. Im talking either way. It is like it's welded in place, Can you offer any sugestions, or guide me to a forum hat could?

    Irhyper - Although I've never had that problem with my 788 (good saw), I've run into similar problems with other tools. I ask one favor of you... before you try my solution, wait a day or 2 to see if others can steer you in a better direction.

    My experience with other tools tells me that sawdust and resin have built up on the #47 part and by your action, you compressed it enough for it to lock. A couple of solutions come to mind in your predicament. First, try a little W-D40 or other thin penetrating oil and then pliers to give you a little more grip, but don't turn it with too much force to twist it. It's not that big of a piece. Second, you can try tapping the turn knob with a small brad hammer to break the sawdust bond. But don't tap too hard and brace the backside so your tap becomes a bond breaking tap and not a delicate tool breaker.

    I really hope somebody else can help you here because I feel I'm steering you down a risky road. Good luck!

      Check with Rick at Rick's Scrollsaw His e-mail address is listed on his website. He may be able to help. He has a lot of good information on the 788 and many other saws.

        Quartz I only bought the air filter, That same model is sold by many distributors, I see Grizzly has it and several others. I was going to build one but this thing works great. I will get a charcoal filter for it also. Great when doing Pyrography. They also had a Pfingst brand flex shaft tool I haven't...

        Carole, only you would cut sprinkles on a scrollsaw. I would probably use rice and stain it. I just gave up replacing my insert. Its worn, but works for what I need. I do sand it to make sure there are no burrs sticking up to scratch the wood. I will be trying the new contact paper when mine runs...

        Thick hair would need a larger opening, thinner hair would require a smaller opening to stay in place. The one being shown in the utube would probably work for thicker hair. They look way better than a pencil or dowel! That elephant sure is cute in her hair!.
