In 1968 I began pistol shooting and thus had to learn how to reload.
Like most people at the time the choice of reloading equipment was limited.
Like many people I started with a Lyman press and Lyman dies.
My experience was one of frustration followed by several failures.
I was inspired by my mentor who just said that reloading 9mm was just fiddly and why did I not choose 38 Special or 45 ACP which are easier to handle.
My answer came in the form of a Bonanza Co-Ax Press which was relatively new to the market. While the Lyman dies worked they were still somewhat fiddly as the die openings are very straight sided and thus each case requires a slight touch to ensure a perfect feed.
When Our children began to arrive I gave up all shooting and reloading activities to concentrate on the raising of the children.
Moving on to 2016, the kids are no longer at home and I have entered the pistol shooting community.
Reloading, now where is my press and all my equipment.
What do you mean it was given away. I am sure this has never happened to any of you on the internet.
I found the Bonanza had been sold to Forster, I ended up with Qty 2 Forster Co-Ax presses, this time I also found Dillon Pistol Dies.
What an improvement, Night and Day.
Well after overcoming the shock of Bonanza no longer in business, I went on to the internet to find an original Bonanza Co-Ax Press.
I found an old and very tired looking Bonanza Co-Ax press on eBay.
Following is my plan to rebuild the Bonanza B1 Co-Ax press to the current Forster B3/B4 Specs.
Bonanza Co-Ax Upgrade
When it is time to upgrade or restore a Bonanza Co-Ax Press to current Forster specifications.
1. Visually inspect the entire Cast Iron frame for possible flaws.
2. Magna-Flux the Cast Iron components for hidden defects in the metal.
3. Strip the entire press down to the cast iron components per the attached notes.
4. Clean the press inspect if the press requires just a thorough cleaning or stripping cleaning.
5. Disassemble by driving through the Bonanza roll pins to remove the Guide Rod(s), Replace with Forster Guide Rods
Qty 2 028271-048 – Guide Rods @ $13.00 USD
Qty 2 new roll pins @ $0.74 USD
NOTE: the Guide Rod, Roll Pins are shorter than the diameter of the Guide Rods
To remove these Roll Pins, the Roll Pins are driven in until the pin touches the Guide Block Casting. Using your Roll Pin Removal Drift Pin and check the depth of the Roll Pin, Once you have the Roll Pin totally inside the Guide Rod, you should be able to remove the Guide Rod. Removal of the Guide Rod requires a sharp rap with a hammer to dislodge the guide rod for the Guide Block Casting.
