A bit of light engineering

I didn’t do much turning yesterday, and last weekend we were away visiting rellies. Thanks to a colleague at work I was able to make some new tools. I have been considering trying out some carbide tipped tools, but the cost was prohibitive, given my very small budget.
I resurrected a bricked laptop, and the owner bought me some of these to say thanks.
Some Carbide Cutters
The lad works for a major DIY store, so I got a length of steel bar with a hefty discount. One bar was long enough for three carbide tools, but so far only two have been made.
Cutters and Bar
Once the bar was cut to length, a small amount of grinding was required to stop the bar fouling the work.
Some Grinding
This was followed by drilling a hole through the bar, and tapping an M4 thread to accept the screws supplied.
Drill & Tap
Unfortunately the hole in the square cutter was larger than the screws supplied, so it will have to be replaced with something larger. I have fitted a brass washer for proof of concept, but I will not use the tool until a better sized screw can be fitted.
The Wrong Screw
Next up was a piece of holly I have been drying since 2013. It’s not fully dry yet, but good enough for tool handles.

Finally the tools are hung on the back-board with the mass produced HSS tools.
The Finished Article(s)
I tried the round cutter out on a scrap piece of beech, and it cut really cleanly although there is obviously going to be a learning curve with the carbide tools.

So far, the cost to me has been around £3
If it turns out that carbide tools are not my cup of tea, then it’s no great loss. Even buying the tips, and more bar, the cost to me would be £5 each. I wonder whether there is any mileage in selling these to other turners?
