Like many others, I have ditched my cartridge razors and went back a few decades. If I have the option to make or buy something, I always chose to make it. These are enjoyable to create and I have made several. There are razor heads available, but no information on how to create or attach them to a wooden handle. Here is what works for me and how I made this lovely Koa handled double edged razor below.
Tools I used to create this:
1/2" parting tool
Round nose scraper
Step 1: Source the materials
With some diligent internet searches, I was able to find a double edge safety razor head at an online retailer called thegoldennib.com. The head is made by Parker and is a fairly decent one. I also sourced a 6 inch long and 1 inch thick piece of Koa wood from Hawaii
Step 2: Square the ends
On my table saw cross cut sled, I squared the ends of the Koa blank by trimming off a very small portion on each end. This is important since it will need to be perfectly centered on the lathe.
since I am working with small parts you notice I am not holding the wood by hand. This can be very dangerous so I want to exercise as much safety as possible while retaining accuracy.
Step 3: Drill the hole for the reciever
The reciever that comes with the kit threads into the handle with a 1/4-20 thread size. To accommodate this, I drilled a 7/32" hole about 1/16" deeper than the threaded bolt extends. This way the threads will bite into the wood and self tap.
You will notice I am using a jig and a drill press. This hole must be perfectly centered. If it isn't you run the risk of an off center alignment, or splitting the wood when you mount the head.
To find the center I simply draw and X from one corner to the other and mark the center with an awl. Do this on both ends
