This post is for anyone who wants to ask Newbies a build question.

Just make sure if you are using the drill press to tap the hole, turn the chuck by hand or you will probably be trying to remove a broken tap (not fun).

Yep that's why the handle on drill press.

Not at All. This post is trying to show anyone interested in one method to drill and tap for a TH. If you don't have a drill press and try to tap free hand it could get real ugly. The TH needs to be counter sunk flush with the filed on/in barrel flat. Don't think a newbie can make that happen free hand. JMO.

As an auto mechanic for 40+ years I've always drilled and tapped and countersunk freehand. But yes it can get real ugly especially on a customers engine, transmission, etc.
Not recommended for a newbie.

Use the handle to move the tap down, but if you turn on the power, it's a guarantee to break the tap that's why you turn the chuck by hand .

Actually you flunked Newbies and more newbies were to reply. You been around since 2012 I doubt you are a newbie unless I flunked math.
Thanks anyway we like to hear from everyone.

As we said in the Army "You are a NO-GO at this station please go to remedial training and come back when your ready to pass". Failure to read and understand the instructions is a failure on attention to detail. I stink at test.

Why not just get a drill press vice and be done with those clamps?

On a tapered barrel you have to use shims in the drill press vice to hold things steady. Wood door shims work good for this.

This threads going to be fun if not funny... But I do all my drilling with power hand drills.

 

[Mgbruch]

Will this quiz be a part of my grade?

Since I don't have an adjustable table I'd shim the wood block that the barrel is clamped to.

My drill press is an ancient delta with a cast iron table that only adjusts up and down, and that by sheer muscle power. I'm getting real good at shimming...

I have an ancient Craftsman that works the same. Add the drill press xy vise and it gets pretty heavy.

In case you did not know: This tool in the chuck, is a spring loaded tap alignment tool. The shaft extending into the top of the tap has spring loaded travel. This tool keeps consistent proper alignment pressure on the tap. No need to be moving the chuck down while hand turning the tap

Good thought, but not for me in this circumstance. My DP vice is on the floor. Be it good or bad, my preference was to extend the table so the barrel would lay flat and solid. I do not like putting a 48" barrel into a short clamp.

PS Don't laugh at my dart backboard. Got grandkids that like to throw backwards under their crotch and then laugh.

I will start with a simple photo and ask......What am I doing here and why?
Please, if you are an old hand and can do it blindfolded, no need to spoil the post for those

You're installing the most precise touch hole liner in the history of touch hole liners. Because that's the way you roll.

 

[Odiesplace]

With all respect to you. I am not a machinist, but a carpenter. I use what I have. I have learned years ago, it don't matter how you skin the critter, just get it done safe and correct. What am I suppose to overcome, the TH is in to my expectations?

I meant no disrespect, I was rather impressed with your creativity . It means use what you have to complete your task

Yes, turn the chuck by hand and turn it forward a little way and then backwards to break the chips. Much less chance of breaking the tap that way. Of course, use cutting oil!

after 21 years in the machine shop I have never seen that tool mine isn't spring loaded

also avoid a four flute tap if at all possible 2 or 3 flute taps are your friends

I had never even heard of a alignment tool untill about 4 years ago, when someone on this forum pointed it out to this ignorant carpenter. I purchased one right away and have been using it where needed.
We can learn something every day if we have our eyes and ears open.
Thanks
