Bluing a Hand Saw

11-16-2019 03:19 AM by A Slice of Wood Workshop | 0 comments »

I have many hand saws. Some are nice and shiny and others have an older look to them. Most of the time I get to choose what they look like, and it mainly depends on if there is an etch or not. This time around I had a Simmonds No 61 saw. It is a 7tpi and believe it is filed for rip cuts. This thing was in rough shape. Very rusty and the handle is worthless. I will be working on a handle later and trying to learn how to make the wheat pattern, but this video I clean up the blade and show how g...

Etching your own copper panels #6: Etch and Finish

11-02-2016 06:57 PM by splintergroup | 8 comments »

Here we are with a etching acid resist applied to the PCB: Next step….. EtchingSimply stated, the etching process needs to remove any copper that is not protected by the resist applied during the previous steps. Copper is very reactive to acids. Traditionally the primary chemical used for PCB manufacturing was Ferric Chloride (FeCl3). I have a “stash” of this stuff from the 1980’s. It works well, but I’ve noticed that it is fairly expensive now ($8/pint, po...

Etching your own copper panels #5: Exposing and Developing

11-01-2016 07:34 PM by splintergroup | 3 comments »

So now I have an image mask and a copper plated panel with a layer of dried photo resist. Next up is to get the image onto the copper by exposing it to the proper light. The LightDifferent brands/types of photo resist require different wavelengths or colors of light to activate. I don’t know of any that do not require Ultra Violet (UV) light. Withing the UV spectrum are several “bands” of color, most notably are the UV-A and UV-B bands. UV-A is the spectrum the resist ...

Etching your own copper panels #4: Applying the Resist

10-31-2016 09:30 PM by splintergroup | 2 comments »

This is where the path forks in many directions. There are plenty of ways/materials to use here so don’t be afraid to look! Especially check out the ‘Alternatives’ at the end. I use a suspicious blue goo from some anonymous Ebay Chinese source. It works well and is inexpensive compared to other methods. Only down side is the 3-4 weeks it takes for delivery. The ResistNegative photo resist is a paint applied to the bare copper surface on the panel. Wherever the resist ...

Etching your own copper panels #2: Process Summary

10-28-2016 07:54 PM by splintergroup | 4 comments »

I’ll give the entire process a quick summary here an then show the details with an actual project. Be aware that there are plenty of ways to accomplish this process, do a web search on “making PC boards” or something similar. I’ve used a number of methods when I was young. Most worked ok, but mostly they had the benefit of being cheap! The Resist: To etch copper with a pattern, you want some method of keeping the etchant away from the areas you don’t ...

Etching your own copper panels #1: Intro.

10-25-2016 07:28 PM by splintergroup | 7 comments »

I’ve been meaning to do this tutorial for some time now, so let it begin…. Etched panels add another dimension to woodworking projects. The great thing is you can create a panel with most any image, no “talent” required. Some examples of copper. The first image has the copper cleaned and then protected with lacquer, the next two have a patina applied before sealing. You can use most any material, if you can find a way to etch it. Metals are a no-br...

Making Plane Blades #2: Etching a Logo

08-17-2015 06:32 AM by bobasaurus | 7 comments »

(Disclaimer: I take no responsibility for anything done with this information, proceed at your own risk.) I like to etch my logo onto plane blades using toner transfer and salt water electrolysis. This technique is commonly used by knife makers to put a makers mark on their blades, and is pretty simple to do. I start by making a logo in a program called Inkscape. This makes a “vector” image that can be scaled to whatever size I want without becoming blurry. I then invert ...

Going Galoot #5: I came, I saw . . . . . .

03-28-2014 02:14 AM by JayT | 16 comments »

Shop’s Log: March 27, 2014 Part of going galoot involves finding quality hand tools. While there are now some manufacturers making high quality hand tools (Lie-Nielsen or Lee Valley/Veritas, for instance) there are also a tremendous amount of vintage tools that make great users if you are willing to put in a little work. I have refurbished squares, adjustable bevels and a ton of hand planes, but was now ready to move on to another vital tool for the galoot ….... hand saws. ...
