don watson Posted July 31, 2017 Report Share Posted July 31, 2017 Hi All, I am having a problem with a SIP 16" scroll saw. When I move the blade from the down to the up position it moves toward the front of the saw about 0.040" When I move the blade from the down to the up position it moves it also move about 0.040". Can this be rectified or is the machine for the scrap heap ?? Any thoughts appreciated. Don W Lucky2 1 Quote Link to comment Share on other sites More sharing options...

JOE_M Posted July 31, 2017 Report Share Posted July 31, 2017 If you find that too much, my Dewalt came very agressive but I did some tweaking to calm it down. You can look at your bottom clamp and see if something like this is possible. don watson 1 Quote Link to comment Share on other sites More sharing options...

don watson Posted August 1, 2017 Author Report Share Posted August 1, 2017 (edited) Thanks JOE_M. Will have a look through this later. take care Don W EDIT I have had a look and it is a very good explanation. It also leads to a 4 part series from the Gwinnett Woodworkers about stripping and maintenance of the De Walt 788 which I will look at later.

Wooden Lace Posted August 1, 2017 Report Share Posted August 1, 2017 I had heard of the 4 part video series from Gwinnett Woodworkers, but trying to watch it on my computer was SO slow, so I looked them up and found a contact number. I called and discussed it with them. Ended up sending them a $20 donation to their club and they sent me the entire series on a DVD. Makes it much easier.

don watson Posted August 1, 2017 Author Report Share Posted August 1, 2017 I have had a look at the saw and found the bottom arm seems t be a fixed length and is not adjustable. The top arm, I will need to remove the plastic cover with the connections for the speed, on/ and off switches etc. I will see if there is anything under there that can be adjusted. I can't see what is causing this fore and aft movement or the sideways movement. thanks again Don W Quote Link to comment Share on other sites More sharing options...
bobscroll Posted August 1, 2017 Report Share Posted August 1, 2017 Hi Don, Could it be worn bearings on the arms or pivot points? That's all I can think of, Bob Quote Link to comment Share on other sites More sharing options...
don watson Posted August 2, 2017 Author Report Share Posted August 2, 2017 Bob, The bottom blade holder is very loose on the end of the bottom arm. I should maybe remove both top and bottom blade holders and swap to see if I can turn the problem upside down ?? Don W bobscroll 1 Quote Link to comment Share on other sites More sharing options...
don watson Posted August 3, 2017 Author Report Share Posted August 3, 2017 Hi All, I have it figured after stripping the mechanism down and re-assembling. Will try and get some pictures in the morning. take care Don W Quote Link to comment Share on other sites More sharing options...
Rolf Posted August 4, 2017 Report Share Posted August 4, 2017 (edited) That front back motion is in all probability normal for that saw. Most saws have some, a few are adjustable. Edited August 4, 2017 by Rolf Quote Link to comment Share on other sites More sharing options...
don watson Posted August 4, 2017 Author Report Share Posted August 4, 2017 Thanks everyone, I have worked out the problem (with help from a good friend). The blade operating mechanism is contained in a 'C' shaped casting and this casting is bolted to the rear of the cast iron base. The left hand side of the first picture above shows the 'C' frame attached to the base. (Also in the centre of this picture is the link between the motor and the arm). This 'C' frame is bolted to the base with 4 hex head 8mm bolts. When the table is mounted on the machine, I can shim the the 'C' frame to square the blade to the table in the left/right direction I can also shim front or back of these 8mm bolts to square the blade in a fore/aft direction. Hopefully this should solve the problem. I am sorry there is no update pictures but it is still raining out and I don't feel in rush. I am waiting on a delivery of Loctite Threadlock before final assembly take care Don W Quote Link to comment Share on other sites More sharing options...
don watson Posted August 8, 2017 Author Report Share Posted August 8, 2017 Hi All, Thanks for your help. The machine was scrapped this morning. The top arm was twisted and there are no replacements available. Pity as it was a pretty solid machine. take care Don W bobscroll 1 Quote Link to comment Share on other sites More sharing options...
