I hear ya. It can be very hard and stressful work.
Point alignment
- Thread starter PracticeChampion
- Start date
For those who don't do points yet or I should say,
Don't totally understand points yet. Try Forearms from someone else.
What you'll learn from them will prove to be more valuable than you could ever imagine. Not only in construction methods but in repairing also.
The main ingredient at the end of the day is YOU!
BREAK IT DOWN, DEFINE IT, WHAT IT IS, AND WHAT IT COULD BE.

Few pictures.. Terrible choice of wood for pictures due to the dark grain but all I got on hand. I marked my tips in white. One above the line and one below which is not terrible til the final tapers and they can be 1/4-3/8" or more off
So I guess on short runs it's not to bad but over a 30" it goes stray. Maybe the bed isn't square or the vibration like I previously thought

Try using a longer piece for the Forearm so your cuts don't end where your center is. It will add stability. This is a 6 pointer, I cut 3 at a time.Few pictures..

I think I understand what your saying but you have a different way of saying that or preferably more pictures?

Look at the photo again. The forearm wood extends past the base of the points. This adds support to the thin section when cutting the points. It also adds a feature that will allow you to verify runout before turning.
Finished Forearm of above. On 4 point cues, I cut all 4 channels. On 6 and 8, I cut the shorter ones first then the long ones after. This way, I can overlap the points into each other. I used that picture so you could see the base of the Forearm.

I gotcha... That's what I was thinking you was saying
Maybe it's cause I'm looking on my phone but that first picture visually all kinda blended together

Your last picture (if I'm seeing it correct) shows the center hole not in the center of the 4 channels.
As mentioned, you need a sturdier and more precise way of holding the back end of the forearm.
This the base of starting the point cutting operation.
Both ends of the forearm need a precision (sturdy) method of being held tight. (absolute zero movement on either end)
As I mentioned previously, this where the still buying stuff came into play for me.
I broke down and got a set of indexing jigs that I would not be without myself after using them.
Others have made their own style but you can't beat Tom's set up.
I can insert and take out of the fixture the forearm 100 times (arbitrary number) during the cutting process if I needed and it aligns itself back to one and only one position every time it gets reinserted.
I could go on about other methods used to stiffen and lessen the vibration on the forearm during the cutting process but that is for a different day and discussion.

Repeat, shallow passes are your friend, as Mr.B has pointed out in the past.
