I'll tell you what I think!

I thought it was a good idea until I wrecked my drill press. If you want to do it, you have to ensure that your drill motor is attached to your notcher and close to your v block. Otherwise it is too much leverage and you will warp your shaft and damage your bearings.

I went to KMS tool in Poco, and they have the cheap arse version and it works great. Cost is like $60.00 Unless you are a pro shop where you have significant output and are concerned about how long the tool will last, I wouldn't bother with anything more (like this one van sant's tube notcher (http://www.vansantent.com/tube_notcher.htm) ) Mine is pretty accurate and fast. The only real difference is the durability (copper bushings and plasma cut bracketry vs. bearings and cnc machined)

Your idea is good but probably not worth the time given your results won't be much (if any) better than the KMS cheapy. :redneck

so you paid 60 bucks for the one similar to the one in your link???
thatll save me alot of time.

a v block is simply a block of steel with a "v" channel in it.

No. I said I paid 60 for the cheapie version I have. My point is, if you aren't doing high volume then you don't need one like the one I linked to. The $60, is pretty accurate and quick but it won't last as long as the one in the link nor will it be as accurate (Not that you could tell unless you were using some kind of digital crazy gizmo). All of my notches have been accurate and square. The one in the link is used by pro race shops where money is no object for tooling (or by people with too much money). I'll try to remember to post a pic of mine over the weekend.
