122. Simple DIY - cut straight using a spiral blade?
Вставка
- Опубліковано 28 сер 2024
- In this video, I try something new; something I've never done before so consider this an experiment. Hopefully, everyone will learn something from it.
I'll try making a straight cut using a spiral blade on a scroll saw by sliding the piece of wood down a wooden fence clamped to the saw table. I'll compare the cuts I get from using the fence to cuts that I make by hand.
Because a spiral blade cuts in any direction, it has been said that making accurate cuts using this blade is more difficult (the cut is harder to control) especially for a beginner. Heads up if you are a beginning scroller.
Spiral blades are plain end blades (with no pins). To use them, the blade clamps on your saw must be able to hold plain end blades. In a previous video, I showed you how I installed new blade clamps on my saw so that I could use plain end blades. Here's a link to that video: • 116. Installing pinles...
Being able to use pinless (flat or plain end) blades opens up more blade choices (there is a greater variety of pinless blades than pin end blades). The pinless blades also require a much smaller pilot hole when making inside cuts.

Amazon also sells many other types of scroll saw blades.

This bladeholder design can be used with several kinds of scroll saws (not just the Central Machinery / Harbor Freight saw). Check the web link provided to see if these holders will work on your saw.

Thanks, this is interesting. I think a straight blade will do better straight if that is aligned correctly with the wood.
No offense, but I think many people new to the scroll saw would think using a straight blade would work better. Unfortunately, because of the way many scroll saw blades are manufactured, in order to cut straight, the wood must be rotated slightly and angled into the blade. New scrollers (myself included) find cutting a straight line to be challenging (to get good at it requires practice and patience). That's why I decided to try using a fence with a spiral blade.
Thanks for your comment and for watching.
I don’t understand why you put the piece across the top of the piece you’re cutting ??
At 8:26, I placed a thin piece of plywood across the piece that I am cutting to help hold it down. I did the same thing at 12:14. I hope this makes sense.

It definitely looks like a challenge to cut straight on a scroll saw with a spiral blade, but it's good to know there are workarounds. Have you tried cutting any letters or more intricate patterns yet, that might be fun. I cut a handle for a wooden mallet on my bandsaw last week, pretty happy with the result. I find it's hardest to cut a straight line when I shave off less than 1/8 in. as the blade has a tendency to pull out from lack of pressure on the thinnest side. If I cut against a fence then it does allow me to go pretty narrow.
Hi Michael. Yes, I have tried to cut slightly more intricate pieces on the scroll saw specifically using a spiral blade. Here's a link to a video where I was experimenting with what I call "tandem cutting"; in the video, I was cutting interlocking puzzle pieces ( ua-cam.com/video/EpZZfUp_Nqc/v-deo.html ).
For you (and anyone else reading this), I'm not sure if you have been following my channel or not, but my channel has been about documenting this journey I've been on:
I'm trying to put together a relatively small collection of very low cost tools that will allow me (and anyone else with the interest) to design and make just about anything (primarily out of wood) that I can imagine (hence the channel name).
This is quite a challenge given the massive number of choices available, but it recently has started to feel like I'm heading toward convergence ("the answer").
I know I can design and print cutting templates for just about anything using LibreCAD ( playlist link here: ua-cam.com/play/PLGCBwUeR2BD2ypYi5k0c4p6M52YO8Z-WD.html ) (LibreCAD allows me to design AND print in 2D at ANY scale!). I know that I can make very accurate inside and outside cuts (given enough practice!) using a scroll saw (playlist link here: ua-cam.com/play/PLGCBwUeR2BD0uF74gOBR3Lh0Mi9hNnA-x.html ). I know that glued wood joints (done the correct way!) can be stronger than the wood itself (video here: ua-cam.com/video/KnDokEpcUac/v-deo.html ). I know that using woodworking hand tools (hand saws, planes, & chisels) is the way woodworkers made everything many years ago (and it is fun!); here's the workbench I made by hand: ua-cam.com/video/osaXlpIFK7Q/v-deo.html .
So as I continue the journey, you'll see me continuing to focus on the scroll saw, LibreCAD (with perhaps a dash of SketchUp or Blender for 3D designs), hand tools, and glued wood joints.
Thanks for your comment and for watching.
@@ImaginethenMake Very cool! I previously worked as a Web Developer, mainly with open source languages like PHP that run on Linux, so LibreCAD is definitely something I'd like to try out, does it handle 3D? I really liked Wings 3D, but moved to Fusion 360 for it's parametric modeling features and CAD focused tools. I am currently subscribed to your channel, but as you know UA-cam employs a peculiar algorithm to recommend videos, and I think it's because your content is less similar to other stuff I watch, like shop tours and people ripping boards on table saws etc. 😁 Thanks for the recommendations!
Hey Michael. I have also worked with web developer programs over the years. Lately, it's been HTML5, JavaScript, and CSS. But I have also worked with PHP and mySQL. Who knows, maybe I'll get back to that stuff again.
No, LibreCAD is only 2D. I started using it because it is open source (free to use) and allows me to draw at any scale (or no particular scale) AND print at any scale. I use it to create drawings that can be glued to a piece of wood; cut along the lines in the drawing using a scroll saw and I have parts for a project (basically, anything I can imagine).
For 3D, I have been using SketchUP 2017 (playlist here: ua-cam.com/play/PLGCBwUeR2BD0gb4j5CHbOJPB3tsXdGODb.html ). This is a really easy program to get started with but is extremely powerful. Trimble, the new owner of SketchUP no longer makes a free downloadable version and the cost of the license for the most up to date version is more than what I want to pay. There are 2 other choices which are free and very useful: FreeCAD 3D ( www.freecadweb.org/ ) and Blender ( www.blender.org/ ). FreeCAD is a parametric modeler so drawing to scale, using constraints, and animation are all doable. Blender is more about modeling organic shapes (movie making) but I think it can be used to draw to scale; and of course very powerful animation is a given; just not parametric modeling.

Thanks for you comment.
I wonder how it would be to attach the piece to a cnc, an move it slowly in a pre programmed shape.
I did a quick UA-cam search and found this video: ua-cam.com/video/R6PrNylf6_8/v-deo.html . It looks like Andrew has gone through a lot of effort and experimentation to try and add a CNC control system to a scroll saw. From what I can tell, the project is still ongoing. Check out some of the other videos on his channel to get a feel for what he has done so far.
