New use for an old tool.

[robcas631]

Hi all,

I had to make two concave cuts out of a 1" square brass stock. One with a radius of 1.125" the other 1.375". I didn't have the proper tool so I improvised. The first picture shows what I used and the others are the results. Enjoy! Guess which tool I used?

An adjustable spade bit?

Nice results! I guess I'm not seeing the picture clearly... what exactly did you do?

It definitely looks like a spade bit. Would never have thought to use one for this purpose.

Looks like it but a decent picture probably would clear this up in most people's minds.

Yes a spade bit @ 1.125" It took forever but worked perfectly.

Todd it's a spade bit. I had to make .002" cuts max. It's done though

And I observed the cutting via a dentist mirror.

Just another example of why one should never through out tools.

 

[SilverSanJuan]

Yeah, I'll bet that took forever at 0.002 per pass. Patience is definitely a requirement in this hobby.

Todd.....correction ofmaterial removal, it's .02"

 

[SilverSanJuan]

Ah, thanks. How much over hang did you have on the bit? Seems like there could be a lot of flex on the tool.
