SPEED CONTROL NOT WORKING ON SCROLLSAW DW788 - Saws

https://forum.scrollsawer.com/forum/scroll-saw/tools-and-blades/52032-dw788-speed-control-issue

replace the control as it is faulty internally

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... :-)

First: if there is looseness in the table, it is dangerous. So I would check all the parts for wear. If, for instance, a knob worked loose, the bolt could have worn (via vibrating) the bracket, resulting in you being unable to tighten it correctly. Occasionally I take mine all apart and check it all over for just that reason. I also check all the knobs just before use to make sure they are all tight. Here is a web page talking about Dewalt scroll saw problems and solutions http://www.scrollsaws.com/SawReviews/DewltTuneUp.htm

Part is $84.00 Are the operators crowding the tool, blades sharp? Scroll saws do not cut quickly.

can you bypass the motor speed controller(circuit board) and hook the line cord directly to the motor? then if it runs at full speed and doesn't over-heat ,you know its still good

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 http://www.dewaltservicenet.com/Products/DocumentView.aspx?productid=5682&typeId=3475&documentId=333

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.
