Having read all the DIY articles on addressing the knocking noise, I pretty much eliminated all that I could find and fix myself. The question I have now is for the Tensioning Rod, Part# 24. From what I can see, this rod (or its parts) does not move when in use. There are no moving parts that come in contact with it while in use. So, how is adjusting this rod a potential solution to any knocking sounds ?? I have a very simple mind. I just can't figure out why some people say this "may be" one of the culprits. So, what am I missing here ?? (before I put it back together again for the 6th time).

So, I was having some issues with vibration and my new saw (Hegner 22"), I was going to move it to a new location, but while I was moving stuff around I noticed that the floor was bouncy. Checked a different area and the floor was not bouncy, I moved the saw to the non bouncy area and the vibration is gone, much much better.

I like to have my major tools on mobile bases. I made a base for my Excalibur 21 using the Porta-mate 1100 kit and 3/4" plywood. That has worked out well and i have permanently mounted a foot rest and the foot switch in comfortable positions. With this base the rear is supported by casters and the front is lowered onto rubber pads. I recently purchased a Hegner 22 and i am considering a similar mobile setup. One advantage of the mobile base for the Hegner is added stability due to the narrow footprint of the Hegner stand. Because the legs are close together i probably can only comfortably position the foot switch, as it becomes awkwardly cramped to place both feet between the front legs of the stand. One concern that i have is vibration. Has anyone else placed a Hegner on a mobile base, and is a vibration problem created by so doing?

Occurred to me with vibration as a topic coming up. I have had a private pilot lic. Kind of outside of the field of scroll sawing. I'm one of those people that have to know how things work and have a trail of childhood devices pulled apart, though I spent the rest of my life putting everything together for my family after the fact. Hung around airplane hangers watching the mechanics work of the plane to understand the insides. One requirement for planes is all bolts and nuts have holes in them. A bolt and nut is tightened to a spec and the holes line up, then "safety wire" is put through the hole and other bolt holes or anchor the stop the bolt and nut from twisting. For cars, scrollsaws that have bolts that just won't stay some safety wire and a hole drill through will keep it there until you cut the wire. There is the safety wire and a plier that has a spin knob to twist the wire. There is different sizes of wire and even some jigs to drill right through the nut and bolt. I doubt everyone is going to run out and safety wire everything on their scroll saw, though when you have had enough of a bolt coming out this is one way that keeps planes up and is dependable.

Hi Folks- I decided to jump into scroll sawing with both feet, and purchased a lightly-used DW788. I had the seller fire it up prior to the purchase, and to my untrained eye, all seemed well. Fast forward a week and a little more experience watching videos, and now I'm concerned there is a problem with the saw rattling/vibrating a bit more than it should. Problem is, I have no baseline for comparison to know what is "normal." Please check out this short video, and focus and periodic "bumps" and rattles visible in the air nozzle. Especially at higher speeds: https://www.youtube.com/watch?v=kLBxPC9gi_I In your opinion, is what you observe considered typical, or could the "bumps" be considered a sign of a bigger problem? Thanks for your advice! Jim

I have had an Excalibur ex-21 for around a year. At first it was really nice and smooth running . It has now developed quite a loud vibration, especially when increasing speed it gets really bad. I have tried online to find a solution. Checked forward backward movement and it seems to be fine. Have checked a bolt at the back of the saw behind the inspection plate, which someone suggested I tighten, but cannot budge it at all it is already so tight. Desperate to fix the problem so any help would be gratefully accepted. I looked in the forum to see if this problem has come up before but could not find anything, so if I missed it I apologise....
