Question about Dewalt & Variable Scroll Saw

Open Question

Hi, I have a 2 1/2 year old Dewalt DW788 scrollsaw. It has lately developed a lot of vibration and won't stay true on a line, even on very thin wood. The blade tension is fine, but could it be the bea

A couple months ago I noticed more noise and vibration than usual. I don't use the saw often, so I waoul be surprised if it had bad bearings, but an internet video described the same symptoms and showed where the bearings were probably worn and how o replace them. Are there any things that I should check first before getting into all that?

SOURCE: Dewalt Table Saw

I don't know about Cleveland, but a while ago I replaced the bearing on my Sears Craftsman saw, and it wasn't a hard fix. I would expect any competent repair shop could do the repair easily. If you can get the arbor off and take it to the shop, that would be ideal. It only takes loosening a few bolts to get it off. I first removed the cast iron top from the sheet metal base so I could turn it over, but it can be done from the bottom, too. Just be prepared to eat some sawdust. The most specialized thing the shop would need is a bearing press to get the bearing in and out of its seat, and many shops would have these; they aren't very expensive. Maybe a good machine shop which does small jobs could do it for a small fee. A good place to find these is at your local auto parts store, such as NAPA or O'Riellys (here in MIssouri, anyway, but you get the idea). Your auto repair shop probably knows one or two they use for 'turning' brake drums, etc. BTY, I didn't have a bearing press and I did the job with carefully tapping the bearing back on with a sleeve made from a piece of scrap pipe. Tauton Press makes a great DVD on tuning up your saw after this fix, as you want to make sure
it is square with the table in two dimensions - parallel to the miter saw slots and perpendicular to the top. Good luck.

SOURCE: Saw has no power.

Does the motor continue to run, but the arm stops? It sounds like the set screw on the motor shaft is loose. See the exploded view at this link. It's called out as # 97

SOURCE: Dewalt DW788 scroll saw noise

hello,,,i just bought a new dw788

Posted on Aug 30, 2010

SOURCE: My saw seems to have two speeds now. Fast and warp

Hi, I fear that the "Nipping" of those wires may have "Spiked" the speed controller, as this indeed, is the symptom of a faulty motor speed controller, I have seen it many times in my shop, you will need to most likely replace it.
You will need to get a workshop service manual, to be able to determine the parts number and how to wire it in once sourced. Either contact Dewalt direct and ask for a service manual, or Google for one using the exact make and model number Please use the link below to choose your location and contact Dewalt direct.

good luck

Fix a dw788 dewalt scrollsaw thtslost its speed cotroll

Do you mean lost as in 'completely missing' or as in 'stopped working'?
The only moving parts are the on/off switch and the speed control knob and variable resistor. On mine, I had to replace the variable resistor pot. You have to get one with the same resistance rating. If you know what it is, you can get them off ebay. Doesn't have to be designed for a scrollsaw. They're all the same whether they're for a saw or for a radio volume control. Only the resistance needs to be matched. (Well, the way the knob fits on the post has to match too.)

How can I cut wood 3.5 inches thick with Dewalt Scroll saw?

nope... throat on scroll saw is of fixed height... beside, all scrollsaw blades are of fixed length, i would suggest use of bandsaw with very narrow blade with minimal kerf. do not use pressure on the blade! you will then have same cut through the thickness of the wood! setup bandsaw correctly, do not overtension it - see my other instructables pertaining to the bandsaw and regulation/setup of it

if you find my solution helpful - do not me shy... give some points... :-)

Cannot access fuse in a dewalt scroll saw dw788

Hi, if the fuse has never been changed it may just be stiff, also when
it says push it may be that your are not pushing in the right direction
some have to slide and push at the same time, however, assumingyou have tried this, then it would make sense to revert to the screwdriver
method , but gently and at the opposit end from the word push...T.C.

I don't use my dewalt table saw during the winter. It is kept in a dry place. The top still shows rust. What can I do to stop the rust?

The best thing I've found to seal saw table tops is a good car wax. It keeps the rust down and is great to keep your work sliding easily on the top and won't stain your wood like oil based coatings would.

Dw788 scroll saw knocking/vibration sound is a link to a possible solution on

It did not fix my problem. My problem is in the "CON ROD ASSY" (part #82) and I found VERY TINY almost microscopic play in the bearing. I took the assembly apart, put it back togerther SEVERAL times and on my last ditch effort, it solved the knocking noise.... I don't think it will last long and probaby just have to replace the part or try to buy the same type bearing for cheap and press it in without damaging it so I don't have to get ripped off on the high dollar Dewalt part.
