make your own carbide lathe tools

by:Gewinn     2020-06-04
I bought my lathe for the second time.
Handed in about a year ago.
This is a traditional set of tools, but nothing special.
Since then, I want to try to replace the carbide cutter.
However, at a price of over $100 per tool, I cannot justify the cost.
After spending some time working on these tools specifically, I decided it would be easy to make them myself.
With materials purchased online and other locally, the cost of these tools is about $25.
This is a savings I can\'t give up for custom tools.
If you want to make your own carbide cutter, you can follow the steps below.
Material: Tools: I have a nice oak in my garage and I can cut two tool handles in half.
Put the blank round and any size you like.
Rotate once and install the spindle in the nova Chuck.
This will help drill out for Tang later.
I copied the thickness of my other lathes because they felt a lot about them.
I got my 14 in. long.
Turn the end of the handle down, just larger than the thread inside the brass cap.
Use the tailstock to apply pressure to tighten the cap in place.
Drill a small hole in the center of the lid so that the real-time center can fix the spindle in place.
Turn the lathe at a slower speed and archive the iron ring.
Be sure to cover the motor and any speed control so that the brass crumbs don\'t break anything.
Illuminate the core with sandpaper.
Use a stepped drill to keep the hole centered.
Drill to 7/16.
Once through the brass, extend the hole to 3 1/2 using a conventional drill bit. deep.
Use calipers and punch presses to mark where the thread is to go.
This will be placed 1/4.
Start at one end centered on the axis.
Use the drill press to ensure that the hole is accurate and square.
Drill holes for threads with 29 drill bits.
I don\'t have the faucet handle so I use the faucet instead of the drill bit and cut the thread by hand (
Not drilling).
Use cutting fluid to lubricate the faucet.
Using a table grinder, remove part of the shaft to keep the carbide blade flush with the surface.
Cut off a relief at the front of the shaft.
This will ensure that the carbide blade is the only part of the tool that will touch the project on the lathe.
Be careful not to cut the thread from the bottom.
Clean the hole using a countersunk bit. Mark 3 in.
From the end of the shaft (
Opposite the end of the thread).
Install the shaft into the nova Chuck and cut it at 3 in.
Mark with saw.
Cut to Tang diameter 7/16 in.
Remove from the lathe and change the shape of the Tang to 7/16.
Diameter with angle grinder and sanding machine.
It is impossible to get this perfect circle (
Look at my picture)
But don\'t stress it because no one will see it.
When working in Tang Dynasty, check the cooperation in the handle regularly.
When the lathe turns slowly, cover the iron ring with painter tape and paint handle.
Using the parting tool, remove the handle from the lathe.
Once it is as thin as shown above, I switch to the chainsaw and remove it completely from the lathe.
There is sand and paint at the end of the handle.
Using the polishing system I made a few months ago, polish the metal pieces to the Mirror.
Mix the two parts of the epoxy resin and slowly add to the hole to try to keep it away from brass.
Once there is enough epoxy in the hole, insert the Tang slowly during rotation to ensure uniform coverage.
Let the epoxy dry.
Use a hex wrench to connect a carbide blade with screws.
I made the second one with my first tool and it worked really well!
When I purchased more oak to match the two handles, I planned to make a third tool to fix the detail cutter.
I can\'t wait to try them in future steering projects.
