Woodworking Tips and Tricks Single Hole Countersink for Wood and Metal

It seems that for any simple procedure, there are only so many ways to go about it and thus only so many tools can be invented to help with the process.   Chamfering or countersinking a hole is one of those.  It is such a simple operation but the tools to do so are very limited.

There are the standard cone shaped bits with varied amounts of fluted cutting edges or only maybe only one flute.  And that’s all I knew about all these decades and they were all unsatisfactory.  If the RPMS are not just perfect, they chatter as they cut (mostly in wood, some in metal) and don’t create a nice bevel in the hole.  No matter what I did to fix this, it just didn’t work and the result was ugly.

Some of the bookbinding equipment I build and sell requires me to chamfer hundreds of holes from 3/8″ to 13/16″ holes, and these holes show for all to see.  I was frustrated with quality I was getting until I discovered “through hole countersinks” or Weldon countersinks, and haven’t used the other kind since.

These are shaped like a regular countersink but have a hole bored through the side that shapes a sharp cutting edge, unlike the standard countersink.  They cut like a chisel, making crisp clean chamfers that look good.  These are sold in sizes from very small (#4 screw) to huge ones.  They also come with pilots, which are really necessary for large holes (like the 3/4″ I use).

In metal, these excel the standard bit.  If you aren’t using a drill press with your work held down, the standard bit will chatter and make ridged chamfers.  And most of the time these bits are used in a portable drill. In wood, it’s even worse, because the hole is usually side grain, so the bit is cutting soft grain and then end grain, and the chamfer becomes irregular, oval shaped.

One advantage with these bits is they are not dependent so much on the RPMS of the drill press or drill.  They just cut at about any speed.  They also can be sharpened with a small mounted cone stone or a small cylinder stone in a drill or die grinder.  After many sharpenings, they don’t cut too well anymore but at least they can be sharpened!  The other ones are throwaways.  If you can find the name brand used ones on ebay for cheap, then buy them, and sharpen them.

They are a bit more expensive but totally worth it.  The end result is worth the price and since they can be resharpened, the extended life is worth the extra cash.

Don’t buy cheap.  Like any tool, you buy cheap, you get cheap.  So buy just one for #8 holes, which 95% of woodworking requires, and see that what I say is true.  You will not go back to the other bits.

Wisdom for the Day

Contentment says, “I don’t need it.”  If I truly needed it, God would have already provided it.

The most profound gift we can give to others is our brokenness.

If your love isn’t hallmarked by humility and sacrifice, it is not love.

Only dead fish go with the flow.

Few can carry a full cup well.

No one ever feared God in vain.

There is no peace without contentment, which flows from being thankful and grateful.

Actions lie louder than words.

The only reason we don’t have revival is we are willing to live without it.

Are the things you are living for worth Christ dying for?

The church used to be a life boat rescuing the perishing.  Now she is a cruise ship recruiting the promising.

Quotes from Books – Revival Praying by Leonard Ravenhill

More quotes from the book Revival Praying by Leonard Ravenhill.

Do we really mean business when we speak of desiring a return to apostolic Christianity?  Are we expecting that it will be God who will make the first move towards revival?  If a farmer had broken no ground and had spread no seed, would he be justified in blaming God because he had no harvest?  With an eye to the sky we sing, “There shall be showers of blessing,” hoping God on high will soon move in revival power.  But aren’t we like the farmer with no ground broken, no seed sown,  and therefore no harvest?

Men hardly expect our soldiers on earth’s battle fronts to make their own ammunition as well as to fire it at the belligerent enemy.  Yet on the mission battlefield, we kept hearing of the lack of conquest when folk at home cease to pray….We are slackers….at the judgment seat of Christ there will be no medals for slackers.

Our churches are more air-conditioned, than prayer-conditioned.

We sabotage much of our praying by disobedience.

Colton said, “Pure truth, like pure gold, has been found unfit for circulation because men have discovered that it is far more convenient to adulterate the truth than refine themselves.  They will not advance their minds to the standards; therefore they lower the standards to their minds.”

Yet God’s first argument with a man is not that he is bad but that he is “dead”.

Wisdom for the Day

People often think they don’t have enough wisdom and strength to do God’s work.  The fact is, we have too much.  When we finally believe we have no wisdom or strength adequate for the task is when we become willing for God to use us and work through us.

Passion for Jesus will do in five minutes what duty might do in a month.

It is not more work that is needed from Christians, but better motives.  We are full of “what, where, and how” but God only looks at “why”.  In God’s Kingdom economy, work with wrong motives is worse than no work at all.

You immediately jump to read a text message from a “friend”.  Why is it you don’t do the same with God’s Text Message to you?

What if to gain what you most desire, you had to give up what you most desire?

Leadership Role in Discipline of Sinful Behavior in the Church

Leadership, Fear of Passing “Judgment”, and the Holy Life

Today, there is a huge failure on the part of Christian leadership in the area of church discipline.  This series of questions was a result of some discussion on the reticence of many (most?) church leadership in passing “judgment” (whatever that means, maybe “casting stones”) on a perpetually sinning Christian.  Then there is this accusation:  “Who are you to pass judgement on so and so when you aren’t so holy yourself.”  If you are in a leadership position and are faced with any sort of church discipline, then I hope these questions will help clarify what the Biblical issues are and what the results are of not following through on an essential to healthy Body life.

I was actually in a position where I had to do just this and it was a very hard thing to do but necessary to the life of the group I was in, as others were being affected by the open sin that was taking place.

These are not sorted into any kind of categories or importance, but just as they came to me.


Is an application of a principle of Scripture a personal opinion?

Is a holy life really that difficult to define?  Is the answer to that question have more to do with one’s own compromise and not wanting to give up a favorite pleasure/action/pastime than the difficulty of defining it?

Is holiness in the Church a “minor” issue or a “major” issue?

Is it church leadership’s role to enforce general Biblical principles, not just specific forbidden acts?

What role does leadership have in insuring that the church remains pure in doctrine and action?

What is the balance for a leader between not judging, and keeping/guarding the purity of the Body of Christ?

“Focus on what’s important.”  As a leader, what is “important”: requiring holiness and righteousness in the sheep or allowing sin to continue by not “passing judgment”?

Is it possible that church leadership has so compromised in their own personal holiness to the point where they don’t know what sin is and what isn’t, and when they are compromising Biblical principles?

Is there a minimum of behaviors that can be required from a Christian for holiness that are indisputable, regardless of whether there are Biblical prohibitions, or cultural differences?  Does a believer’s “freedom in Christ” take precedence over Biblical mandates?

We are commanded to be HOLY.  Is “not judging” enabling the Bride to not to be holy?

Is it possible that our immersion in the culture, “being of the world”, keeps us from rightly judging ourselves according to principles of Scripture?

The main question to ask when something is not clear in Scripture is, “Will this enhance my personal holiness?” That question will answer most of what we face every day.  Rom. 12:1,2

If there isn’t a clear Biblical prohibition against an act, then what role, if any, should Biblical principles play?

Did Jesus die for the very sins that may seem disputable or only for sins that are blatantly forbidden?

Is it possible to be so immersed in one’s culture that we can’t see beyond it to the call to holiness?

Does culture, through time, change the application of Biblical principles?

Is it possible that my personal entertainment has become more important than my personal Holiness and in the process, dilutes the Voice of God in my conscience against the principles of Scripture?

Wisdom for the Day

If you are not careful, comfort and compromise move in.

If our greatest need had been information, God would have sent an educator.
If our greatest need had been technology, God would have sent us a scientist.
If our greatest need had been money, God would have sent us an economist.
But since our greatest need was forgiveness, God sent a Savior.

Marriage was never meant to complete you.  Only Jesus can do that.

Satisfaction driven by selfishness will never satisfy.

The language of the soul is not words but emotions.

Faith is an action that says God is telling the truth.

In individuals and churches, busyness will make you “The King of Shallow”.

You may believe God can use you, but do you believe God will use you?

We usually give priority to distractions.

Wood Tips and Tricks … Old sanding belts

If you do any sanding with your belt sander, you will eventually end up with a box full of old sanding belts.  Some of these may still be good and can be resurrected using this tip.

But some are just past their usefulness.  Maybe.  If you are being too frugal, then you may have a few with no sanding particles left on the cloth and these are trash.  But there will probably be some with enough grits for another purpose.

I use them for sanding metal.  I bought a cheap well-used Craftsman sander on ebay and mounted it so the belt sander is on edge with the belt facing me, horizontal (although it could be mounted vertical also).  I put the “worn out” belts on this sander and have sanded a LOT of steel this way.  Some of what I make in my shop uses 3/8″ and 5/16″ threaded rod and I cut these to length from long pieces with an abrasive cut-off saw.  This leaves the ends very ragged, so they have to be sanded.  I sand them on this sander and then run them against a wire wheel and they come out looking like a factory finish.

A note about the belts: If you are buying cheap belts, then this probably won’t work.  Only belts that are very dark in color with heavy cloth backing will work.  Cheap light colored belts won’t and are barely good for sanding wood.  The best belts are expensive but you will get 10 times the life out of them compared with the cheap belts.  After going the cheap route years ago, I  decided that some things were worth the money.  Same goes for good sandpaper.  I only use Klingspor now and nothing else.  Their sandpaper and belts have taken away a lot of frustration I was dealing with in the past.  I recommend them completely.  They have belts of just about any size and if they don’t have it, they will make it for you.  And no, I don’t get paid for saying so.

Good belts take a lot of abuse and very rarely do I tear a belt on wood or metal.  But be careful of the sparks that come off, so you don’t start a fire in your shop.  Wives, neighbors and insurance companies have a tendency to complain about that sort of thing.
