Hello I recently picked up a Delta 40-530 saw with stand for 40 dollars on a classified site. The only thing wrong with it is the top of the air diaphragm is broken off the top where it connects to the hose. Not sure if any of the readers would have this item. Richard

The bellows on scroll saws do not last very long. I have given up on them and have mounted an $8 hair dryer next to my saw blowing the dust aside, Works great.

I will try and find the link to the video we did on using a fish tank air pump and plastic tubing to make one for an older craftsman that originally did not have one. It works well and can be added to almost any saw.

This site has an aftermarket blower bellows that might be an option:

You might search Youtube or the internet in general for other DIY blowers. One idea I remember seeing somewhere is to use an air dust blower made for blowing the dust off of camera lenses.

I’ve been able to repair the bellows on at least one Delta (not the same model) using rubber cement – the stuff used to repair waterbed mattresses. It adheres well and is flexible so it doesn’t crack when flexed. I repaired my current saw over a year ago and it’s still working great. Another alternative is to use a fish tank air pump that can be connected directly to the blow tube on the saw. Depends on how bad your bellows is damaged.


PS: I believe the stuff you can get for repairing auto tires is the same rubber adhesive – so that might be another alternative you can find locally.

Thank you for the response Brad. Unfortunately it is the top the is broken off the diaphragm where it pokes out of the top of the saw. Richard
