Jpaskell Posted January 17, 2022 Report Share Posted January 17, 2022 Good morning all, Just set up my new Delta scroll saw 40-694. Have the table set in the indent and table at 0 deg. However the saw blade is very close, like a out 0.006 the the left side (edge)of the hole. Not sure how to adjust the table to move it or the blade to the center. Any tips or hints would be helpful. Thanks, Jim OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Dan Posted January 17, 2022 Report Share Posted January 17, 2022 Welcome to the Village, Jim. There are several members with that model saw and they will chime in shortly. Can you post a photo of the hole/blade? OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Jim McDonald Posted January 17, 2022 Report Share Posted January 17, 2022 (edited) First thing is to check and make sure the blade and table are square. Just because the indicator is at zero doesn't mean everything is right. My DW788 was about 1.5 degrees off out of the box.

kmmcrafts Posted January 17, 2022 Report Share Posted January 17, 2022 If you're talking about the blade being off center from the hole in the table, you can loosen the screws on the table ( under side of table ) to the saw and center the blade in the hole and re-tighten the screws.. I had to do this with a couple saws I bought over the years.. Woodrush, crupiea, Dan and 1 other 3 1 Quote Link to comment Share on other sites More sharing options...
CharleyL Posted January 17, 2022 Report Share Posted January 17, 2022 You can also move the blade over or make it closer to straight up and down in it's travel using the Allen screws that are located on the opposite side of the blade clamp bolts. These sometimes will back out from saw use too. With the blade removed, turning both a bit counter clockwise the same amount will move the blade to the left and turning them clockwise will move the blade to the right. With the saw running very slow, watch to see if there is no blur in your view of the blade with your head down and looking straight across the front of the table and watching the blade. Increase the speed gradually while watching. If your view of the blade is a solid straight line you are good. If not, either the top or bottom one of these set screws needs to be turned slightly, but always remember to make the adjustment with the blade removed. When testing for blade/table truly vertical, I use a small block of wood about 2" cube that I cut perfectly square and then check with a try square to assure that it is. I hold it up to the side and back of the tensioned blade and look for gaps between the blade and the block. A bright light behind shining toward the block helps to see the gap. Once you have adjusted the table and/or the blade as square as possible, make a shallow cut into one side of the block just to make a kerf line. Then remove the block and look to see if the cut line is parallel to the side of the block. It also sometimes helps to turn this block around and see if the blade easily slips into this cut line from the back. If it does, the blade is exactly 90 deg to the table side to side. Front to back is more difficult, since there is no real adjustment for that. If it is not 90 deg when checked against the block of wood with the block against the back of the blade, loosening the blade mechanisms where they are screwed to the upper and lower arms of the saw will let you move them slightly forward or back in the screw holes may be enough, but you may need to dis-assemble and then file these screw holes in the arms a little to get more adjustment. Before doing this try to just move the lower back and the upper forward, or the reverse of this, and tighten the screws. Then run the test with the block of wood against the back of the blade again to see if you made a difference. Only do the filing if absolutely necessary. Whenever I install a blade, I always put moderate finger pressure down on the upper blade clamp as I'm tightening the 2nd blade clamp. Doing this assures that you have removed all of the play in the blade moving machinery, and your tension adjustment will be the same every time. Happy scrolling. Absolute adjustments like this aren't necessary until you begin cutting thick wood, stack cutting, or 3-D cutting. Enjoy your saw.

dgman Posted January 17, 2022 Report Share Posted January 17, 2022 (edited) Usually it’s just a matter of loosening the two screws that mount the table to the bevel gauge. Then adjust the table as needed, then tighten the screws. By the way, welcome to the Village! We are a helpful group, so don’t be shy.

I have a picture, but being at a technology level of a 3rd grader, I figure out how to get it in here. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Jpaskell Posted January 17, 2022 Author Report Share Posted January 17, 2022 All, Thanks so much for all the replies. Got it done. Easiest thing was to follow suggestions by kmmcrafts and dgman. I had forgotten the trunion has slots in it. Loosened the bolts aligned it up and blade is very near center. Tighten bolts and all is good. Thanks again to all. Next time a problem arises, I'll pester y'all again. I truly appreciate the comments and help, Regards, Jim John B, OCtoolguy and kmmcrafts 3 Quote Link to comment Share on other sites More sharing options...

I truly appreciate the comments and help, Regards, Jim it's ok to just chime in on most any subject and we'd all like to see pics of what you make with your new saw. We all love pics and they are very simple to add to any post as long as you have them on your computer or phone or whatever device you are using. Just click on the "choose files" just below and it will prompt you to go where the pics are and then just click to add. Quote Link to comment Share on other sites More sharing options...
Jpaskell Posted January 17, 2022 Author Report Share Posted January 17, 2022 (edited) Dan, Thanks for the info. I'll give it a try. Got it. First one post repair, second pre repair. Graduated to the 4th grade. Thanks again, Jim Edited January 18, 2022 by Jpaskell CharleyL, Jaguarguy, John B and 1 other 3 1 Quote Link to comment Share on other sites More sharing options...
