« Part 3: Template me this, Curve me that. Part 4 of Frame Saw Build series Part 5: Sawing the Saw »

It’s snowing here so Its out of the unheated shop and staying indoors – good time to make the blade clips.

I chose to use stainless steel because I waned a material that won’t rust, be strong and capable of sustaining the blade tension, and I like the color (not a big fan of brass although I do like it as an accent in some cases). I ordered some 1/2” stainless steel rods from Speedymetals a while back for no real reason when I ordered some other material as it was on sale (the SS rods) and I figured I will mostly likely end up having a use for them. the day has come!

First thing first, I turned a step in the rod. While the main shank is 1/2’’, I stepped it down to 1/4’’ for about 2.250’’:

This does a couple of things:

1. the 1/4” shaft closely matches the mounting hole in the blade (more about that later)
2. the step down will work as a stop to resist and generate the tension on the blade without putting that stress on the wooden handle as can be seen here:

Next was an idea that I had to avoid having to pin the blades and have a tool less setup to replace blades. I wasn’t sure how well it would work, but decided to go ahead and give it a try. I milled half the thickness of the 1/4” rod off towards the end, and left about 1/4” full round at the edge (not the best way to hold the part for milling, but for this purpose it worked just fine):

Using a file I rounded off the front ‘nub’ and using a hacksaw following the flat I notched that ‘nub’ (had a hard time getting a good picture of this with my phone but you can get the idea):

The reason for this is to create flat that the blade can rest on, with a protrusion that will fit in the blades mounting hole, and the notch registers and locks the blade in once tension is applied on it:

WORKS GREAT! I am very satisfied with the results so far.

Last but not least I notched the 1/2” diameter end of the mounts 0.120” deep (seemed enough for it’s purpose without sacrificing the material strength). My plan is to trim a piece of wood to fit in there, and when I fit the wooden handles on top of these with glue later on the block of wood in that notch would glue to the wooden handle and will lock the handle to the mounting clips by keeping it from pulling out or turning in it. And so I have the 2 blade mounts ready:

Time to plan the next step, which might be trimming the blades to size (I ordered long blades, but intent to have a shorter saw than what those blades were aimed for).

Thanks for reading,
Peace.

I love that you are making the hardware as well. This is something I want to get better at.

Cool project. I am very jealous of the lathe and mill. Nice job turning the SS.

Looks great. Just be careful when you glue the rods into the handles. You might want to either make a small flat or a slit to let the glue come out and not keep the handles from seating all the way due to the hydrostatic pressure. I made a few sets like the Grammercy kit as a learning experience when I first got my lathe.

Hardware’s looking nice. The stainless choice is definitely unusual but it makes perfect sense. I’m no less jealous of your mill. I really want one.

David Thanks for the note. I’ll make sure I leave some recess behind the rods in the handles. I was actually only thinking about applying glue to the wooden part in the notch as I have doubts how good the SS would glue to the wooden handle and all I need is something to keep it in place from moving.

Al the SS sure is heavier than brass… I may still regret this at some point, but since this is a removable part I can always remake it if necessary.

WOW, those are great toys you have for working metal.

It appears you are quite capable with them.

NICE job.

Thanks Lee – I try. in fact I’m eager to find projects that involve machining or metal parts so that I can get more practice at it.

Sharon:

I have been spending time making tooling for my lathe and mill to get in some practice projects. So far I have been making brackets for DRO, tool holders for QCTP, adapter plates for collet holder to rotary table.

The other side project has been very slowly building parts for a CNC router. Lots of fun.
