How to taper a large hole
Hi everybody, I am building a poker table and need to make holes for the drink holders. The drink holders themselves is tapered (I would guess about 8 degrees, imagine the shape of a normal beer glass). The outer dimension is about 70mm (almost 3"). I can drill a "straight" hole quite easily that will accept the drink holder and that will work just fine. However, the table is made from solid kiaat wood so I am trying to really make it look very professional. Also, if it is a tight fit then there is less likelihood of somebody spilling their drinks as the drink holder will not tip. As such, ideally, I would like to taper / bevel the inside of the hole so that it is matches perfectly with the cup holder.
I tried to search online but I have a feeling my key words are wrong. This is what I am currently considering:
- I can use hand tools (rasp) but as I need 10 of these, not sure if I will be able to replicate the results each time.
- I could try to use a dovetail router bit that closely matches the bevel and basically route it from the bottom.
- I can use a straight bit with a slightly smaller bearing and just do a step approach each time taking a mm or 2 as I progress upwards. The angle can be achieved by setting the depth of cut. Once I have the "steps" I could just sand the ridges.
- I can tilt a router 8 degrees (I do have a Makita router that allows angled cuts) but this sounds extremely dangerous and is something that is generally only recommended when you have a flat fence guide.
- I can turn a replica of the cup holder on a lathe, attach some sanding paper to it, then put that into a drill press / oscilating sander and just work the hole like that.
- if the work pieces wasn’t so large, I could potentially mount small blocks on a lathe and just bevel it that way
Just some extra information about me / the project:
- the wood that will accept the drink holder is about 20mm thick
- the wood is kiaat (very similiar to teak)
- Each "player station" (i.e. piece of wood that I need to make the beveled hole in) is 720mm in width and 180mm wide. Thus the pieces could be man handled quite easily.
- I am based in South Africa, so we have a limited selection of tools available
- I am just a hobbyist but am comfortable with power tools and hand tools (just a bit lazy to pick up the hand tool first)
Now, I am sure I am not the first person that ran into the above issue, so I think I am missing an obvious trick on how to pull this off. Now safety is quite important for me hence me rather asking how other people will do it
