This instructable will show you how to improve an inexpensive scroll saw. This type of scroll saw typically accepts blades with pins, but comes with adapters for pinless blades, which are more commonly used. Specifically, I obtained this scroll saw from harbor freight tools, which I think is a great place for hobby tools.

Although you can purchase knobs, they are typically very expensive. For me, a #10-32 screw costs $0.09 versus a knob which costs $2.80 which I found at a local Ace Hardware store. I will show you how I made my own knobs for less.

Step 1: Original Adapter

For reference, this is the original adapter. To use pinless blades, the blade must be inserted between two adapters and tightened with a hex-wrench. When there is no tension on the blade, it does not stay on the scroll saw body and falls off, since tension holds the adapter to the scroll saw.
<p>Um hey dude, you have those adapters entirely installed wrong on the saw. They are going to come flying off. They are supposed to be &quot;Under&quot; that top metal flexible lip. Look under there, you will see a small indent where the metal rod on the adapter is supposed to sit. They aren't supposed to go on the outside like you have in these pictures</p>
<p>As far as I can tell, they do sit in the indent, maybe your perspective is wrong? Otherwise, I've been very lucky because even with &quot;wrong&quot; installation, I haven't had any failures.</p>
why not just use wing nuts, instead of going thru the trouble to make the knobs? also, how are they holding up?
<p>It was easy to find wing nuts, but getting wing screws was difficult.</p>
I replaced the center insert with a solid piece of wood. I was tired of the flimsy black plastic. Simply measured the diameter and what thickness I could fit. After making the piece fit flush with the table, I drilled a hole large enough to pass the blades through.
Well, .... I use mine without the side port.
I did that too. I originally planned to use two knobs per adapter, but it looked silly, so I used the other two for the side port.
I don't scroll like I used to. I have a couple saws now but my Delta is my best one. Recently at a yard sale I saw a Hawk for sale but being as I don't scroll so much anymore I passed on buying it. People really into scrolling swear by Hawk saws. I don't know, I guess my Delta is OK. The other thing folks who are really into scroll saws swear by is Flying Dutchman scroll saw blades. A Hawk saw might be out of your reach, but you can probably afford to buy some Flying Dutchman blades and give them a shot in your saw. I'm not saying it'll turn your saw into a Hawk, but it might be an improvement. <br> <br>Other than running decent blades the other thing you can do is bolt that saw down to something really heavy. By something really heavy I mean like a stand made out of thick steel. Attached to that kind of mass it might make the saw somewhat smoother. Mass dampens vibration. By really heavy I mean massive, a couple hundred pounds at least. Find an old straight engine block and bolt the saw to that, with the head removed of course. Naturally this makes the tool less portable, but sometimes you have to sacrifice some features in order to gain others.
