drill and tap guide?
I need to drill and tap some holes by hand I was wondering what peoples thoughts are on using guides to get them straight.
I found this Torquata drill guide at Timbercon http://www.timbecon.com.au/products/...ies-363_0.aspx
Tap Guide: http://www.tapguide.com/sess/utn;jse...dex.shopscript

The tap guide looks useful. As for drilling, I'm afraid that IMHO you need eitehr a drill press or a lathe to get the holes properly vertical. I have never heard of a successful use of the Torquata or similar guides for something like metalwork, where accuracy is paramount.

You have a CNC mill and a lathe surely you should be able to design and make a Drilling Jig or Guides to suit your needs.

depending on what angle your taping put the tap in the chuck of bench drill and hand turn while piece is held in vice. you can always off set the table if your machine does that also.

Thats a pity having such a usefull feature on a hobby machine but not being up to speed with it yet.
Is it possable to use it as a manual mill,if so no problem.

Not sure on what particular job you are doing, but... ... There are three taps in a set for a reason, use them. The first tap does two things, allows an easy start and gives room for error and adjustment before full depth of thread is cut. By the time you have got to the plug tap, it is too late.

I've got the hang of single sided machining on the mill as long as I am working with square stock. I've yet to master multi-sided machining and machining parts that are not square (eg. machining an existing part). I can do manual machining via the Mills MPG which is a bonus.
The Lathe on the other hand. I haven't spent much time on it at all, so it is still mostly voodoo to me.
My biggest problem is having too many other interests so I haven't been able to put the hours in for some learning. I'll get there eventually.

Mate just push a center drill into a piece of round bar that you can chuck in the drill chuck of the mill . Then after a hole is complete just chuck the centering bar bring it down on the tap end as you hold the tapping bar and feed the quill down as you turn the tap back and forth after a while the tap is well in and it dont need any more support to stay straight for the rest of its travel . The other end could have a 60 degree point for the larger taps.
I should add that the verticle spindle is not turning just feeding down for support.
If you have a drill press or a verticle mill then you don't really need a tool like the one you link to.

Can you swing the head of the mill off to one side and do it with the job supported from the floor and leveled up ?

Oh well you may have to do it manualy with a guide of some kind as you say.
