Hi guys,
I haven't tried this yet, but I want to start building smaller projects, which require smaller tooling for my benchtop tools.
From my experiance in reaming and boring a hole with a boring bar, in my lathe, I find that I can get a more acurate cylinder bore with a boring bar.
Not to say that my reamers don't do a good job, but it seems like if the preliminary hole is off a bit, from drilling, that a reamer in the small diameter sizes, don't do a good job in correcting it unless I run it in and out like a boring bar, the finioshed hole diameter is of course larger, but a reamer in the small dia, seems to have some flex to it that will follow a crooked drilled hole.
With all that said, I was thinking of making very miniature sized boring bars, without having to purchase them.
I was thinking about using a 1/8" , 3/16" and a 1/4" dia. reamers, and modify them to work as miniature boring bars.
These 3 sizes would take care of the smallest cylinder bores I would be working with.
The way this would be done, is I would grind back all the flutes except one, and this one flute would be ground back top and bottom, leaving a small bit unground, at the very front, past the tapered front, wich would act as the cutter.
Would this work?
Any suggestions on why this would not work?
Thankyou.
