Tool jig for drilling a hole in round stock...or something like that--ideas?

[LittleWatchShop]

I am fixing a K&D winding arbor.  I need to drill a hole into the round post as shown in the photo.

My lathe provides the ability to drive a drill bit with near zero runout.  But...how do I hold the target so that the hole goes straight through.

Right now I think I need to design a jig that attaches to the tailstock, but maybe there is a better way that I have not thought of.

Any ideas?

Hi there is a jig on ebay for drilling round stock, like a right angle with a movable arm  which sets the vertical line or there is one like this one on the link

Aha...good concept.  I need to shrink it down to mm dimensions...working on it now.

When drilling through round stock I always use the poor man's hole jig.

Take a bit of round stock the same diameter as the item to be drilled, or turn a bit to the correct size, place the cutoff Inthe lathe and drill a hole the correct size through the cutoff, then place the workpiece in a vice on the drill press with the drilled cutoff forming a T with the hole in line with were the hole is supposed to be then drill through the cutoff into the workpiece., I find it gives good results and keeps the drill straight as it passed through the workpiece.

Quicker to do than wright about.

I printed a jig that did the job.  Not perfect.  Still broke several bits and am not on my third try.  Holes are drilled...did them first before turning the arbors.  This has been an all-day job.

Here is the final product.  The arbor and pins were turned to fit the original knurled knob.

Thank lws.  I've not even set my lathe up yet, waiting to speak to someone about stripping down the spindle. I'm a little apprehensive about working at this scale. I was a joiner and builder by trade. Woodturning yes, extremely small metal turning
