well... If you ABSOLUTELY must use a router for drilling, and I am NOT by any means speaking from experience because I think it is absolutely nuts... harbor freight tools makes a piece that allows you to vary the speed that your router runs. I do not know how slow it will let you go, but it may get you closer to the speed that you will need to successfully accomplish what you need to do...
Steve....I would not recommend using a twist drill bit or any other drill bit in a router unless it was specifically designed for that use. You have to remember, that a router is spinning at up to 20,000rpms....if that steel bit breaks up, you potentially have a very big on your hands.....no pun intended! If you can't drill the holes using a drill press, and you have to have these holes drilled exactly perpendicular....There is an inexpensive attachment to turns a hand drill into a hand held drill press. It bolts or screws onto the collar behind the chuck and has a mechanism similar to a plunge router's. If you have the $$$$$, Buy yourself a bigger drill press......You will find it invaluable in the long run. You can probably pick up a used 14 incher for $150.
I like DannoG's idea. I'd take it one step further, and drill your bridge mounting holes through it. In other words, place your bridge baseplate over the wood, (hardwood like maple) and drill all the holes, not just the string through holes. That way you can use the bridge mounting holes with some longer screws to screw your template to the body, locking it in place. And since you've used the actual baseplate, you should have perfect alignment when you install the bridge. I can't endorse using a router. I have that adjustable depth drill press that kd has pictured, and it's the greatest. If you're going to upgrade your drill press, definitely get one like that rather than one that's just barely big enough for bridge holes.
So I need to drill the holes for the strings to pass through a solid body fitted with a strat-type hardtail bridge. Would it be possible to use a router as a "movable drill press" with a drill bit (say 1/4) fitted into the collet? I've always heard that using a router for drilling was not recommended, But recently I saw that Trend do a range of drill bits specifically for the router. Do I need to use these only or could I use a regular drill bit? Alternatively could I use a straight router bit of the correct diameter and just plunge straight down to make larger holes (bridge / tailpiece studs, for example)?
In the newest Manufacturing 101, we will discuss cutting edge honing and why it matters. Honing the cutting edge is a process of smoothing and refining the cutting edge of a tool. The process involves removing any irregularities or imperfections that may have occurred during the tool’s manufacturing or use. The honing process is essential to ensure the tool performs optimally and delivers accurate and precise results. Here are the benefits:
You know when you need to drill holes absolutely vertically. It's fine if they're near the edge of the body beacuse you can use a drill press or similar. The problem I have is when I want to drill holes further to the centre of teh body, and the throat of the drill press doesn't give me enough reach over the workpiece.
Cutting-edge honing is a critical process in ensuring optimal performance and tool life. Honing removes microscopic irregularities that can lead to premature wear and tear, improves accuracy and precision, reduces chipping and breaking, saves time and money, and enhances safety. If you want to achieve optimal results from your tools, honing is a process that should not be overlooked.
As a temporary, cheap alternative to a new drill press, take a block of squared up hardwood, such as maple and drill guide holes of the proper diameter in it with your drill press. Then use it to align your hand drill on the guitar. It is tricky to drill in just the right spot, but if you make carefull measurements it should work well. After you have used the guide a few times it will get sloppy and you can make a new one. for the string through holes you could make a guide that spaces all 6 strings precisely, using the drill press.
