Title: Do I Need A Drill Press?
Post by alfakilo on Dec 7th, 2019 at 3:33pm
How do you drill accurate holes for prop bearings and other jobs that need precise angles? I'm not very good at using pin vises or Dremels for this kind of work.

There are small drill presses for about $100 or less. Worth the money?

You can get an attachment for a dremel tool cheaper. For example, see: sample drill attachment

It is Christmas time.  I did use the jig for a hand drill for years.  But last Christmas the family got me an inexpensive one at Harbor Freight Tools for around $69 bucks.

I've spent time looking over both tools and lean towards Tom's idea. There are many versions of the drill holder type, and while the price is attractive, I'm concerned about the run-out (or 'wobble') of the concept. When my objective is to drill a precise hole, 'close enough' may not hack it.

Does anyone have an alternative?

I use a Craftsman tabletop drill press similar to what Tom pictured.  Have had it since the mid-90s.  I've found it to be a worthwhile investment, both for modeling and various home improvement and auto activities.

For some reviews and pros and cons (and prices) for the various bench-top drill presses out there, try this link:

If this is the Dremel item, it is the stand only. The Dremel drill has to be bought separately.

The price is good but I'm concerned about how stable the Dremel drill is when mounted. Is there any run-out? If so, then it may not be accurate enough for drilling prop shafts.

Tom, is there any run-out to deal with?

I'm sure it varies with each machine. Mine is not to the degree that I've noticed any wabble in my nose/prop blocks. 

Before I got my drill press and lost my hand drill jig in a move, I made me a drill guide by cutting  90 degree triangle and glued it to a 1/8" thick square base.  I then decided what size music wire I used most for my prop shafts and then glued a brass tube that fit the drill bit and glued it to the 90 degree angle on the square base using my machine squares to keep it sq on the angle and base.  This became my drill press for a few years.  You just need to leave enough length for the drill bit to pass through the article being drilled, like prop blocks before carving, nose/prop block etc.  Hope this makes sense.  "Ve modelers have Vays" paraphrase of what Shults used to say!

I tend toward Mkelly's solution and the tabletop version if you are doing modelling and the occasional home improvement work. Stick to the usual trade names, Delta, Craftsman, etc. as they are reliable, have different speed ranges, sturdy castings, usually take bits from 1/16th to 3/8s and more importantly nationally available spare parts if needed. Also, the national brands are available locally and don't need to be shipped, no damage there and you will be working same day.

I bit the bullet and bought the Dremel Workstation stand. On sale at Lowes for $38. I have a Dremel #395 gathering dust and I'll use it in the mount. Will post results.
