First royal blunder of the year!!!
« on: February 13, 2003, 12:22:55 PM »
Hello Everyone, :D

Well, the first great mess up of the year, but I have high hopes that it wont be the last.

Just got my first supply of copper tubing and my brand new copper tubing cutting saw from Corbin. I got out the books and went to town, cutting and making my first tubing jackets. I think this would have been a good day for me to just to have stayed in bed. That front pin in the front of the swaging press has been bending back and forth for a while, that and the added pressure of a too long of tubing jacket finely just sheared that pin off. So now, I cannot get the other part of the pin out and for what ever reason I cannot get the core seating die out of my press either. I figure sense the press and die is going to Corbin to fix my royal blunder, this is a good time to have that upgrade done to the press. So, I guess not all is lost.

I just have to keep a  :grin:  on my face because if I cannot afford to make some mistakes then I should not try to play around in the swaging game.

My daddy always said “If anything is worth doing, it’s worth doing right.” I guess that goes for messing up too, because this is one dussy of a mess up.

This is my eat crow post. :oops:

Donna -  
  Sounds like you learn just like us - the hard way.  

This is the first I'd heard of a copper tubing cut off saw - but it really makes sense to cut rather than deform.  What do the theeth on the blade look like?  How does it clamp without distorting?

Yes, the cutting saw from Dave Corbin is really nice and well built too.

Richard Corbin has a copper tubing cutter saw too. But it looks like a converted miter saw. http://www.rceco.com/Images/Imagetube%20cutter.jpg

The teeth on Dave's saw are real tinny and it is for cutting aluminum and copper. The clamp holds a 5 ft long section a copper tubing unsupported, except at the cutting end securely, with out crushing it, as you can see from the pic’s. Although I am using .035 inch thick wall tubing, its quite strong.

Thanks for the pics, Donna.

It looks like a straight forward cutoff saw scaled down to size.  There's enough information to calculate speeds and feeds.  Clamping looked basic and secure - simple design (meaning well thought through) with cut being made right-much close to the clamp to eliminate vibration.  I'll bet it even works well.

Donna, I'd like to know if that CSP-II upgrade (modifing the ram and body to allow the stop pin to provide support using both sides of the body) will work on your current series of ejection punches, or will you have to get all of those modified, too?    As I've mentioned before, I think the stop pin is the weak link in the CSP-II press, and rounding over tube jackets probably puts the greatest stress on it. At 60,000 psi they don't last long.   8)

:D Hi Donna.

I gave up on Daves press for just that reason and got one from Richard.I think that is a lot better press.now I use Daves press for a loading press for the long cases like the .45-120(3 1/4')its ideal for that job.
Donna put your press in the long stroke mode and lift the lever in the oposit direction and try to straighten the pin or even cut it if you have to and it will fall out the bottom of the ram.Or you have to send it in.
I chose not to have the up grade for my press for just a little more than the upgrade costs you can get a Wallnut hill press,and Richard will make an adapter so you can use Daves dies.

As for as the saw I looked at it real hard it's nice,but I took a old chain saw chain sharpening saw and put a blade on it.It's just not as good looking but it workes great.Lp.
Dont go were the path leads,go were there is no path and leave a trail.
