Some of my self-made machines.

Don't be surprised that it now only says “Bruno” under my avatar. That's one and the same person. I have two accounts in this forum.

Many problems with the forum. But that's a completely different story.


But now I want to continue here.

A few decades ago I got carried away and built some steam pumps for 5 inch locomotives. The first campaign resulted in 14 pumps, all of which were gradually sold. A few years later I was again asked to make some pumps.
This series consisted of a total of 7 pumps of the same design. They are also all gone.
A few years ago, that was right before the coronavirus pandemic, two club members asked me to make two larger pumps for 7.1/4 inch locomotives. At first I wanted to turn them down, because it is a lot of work.
I then agreed and made two symmetrical pumps.

Inspired by an article in a forum, I made a drilling and boring head for my Wabeco milling machine.
The shank has a Morse taper 2 and is a purchased part.
I made the head from the existing material cross-sections that I had in my box of material scraps. The tool holder has a diameter of 8 mm.

Hello guys and girls.
I had some problems logging back into this forum, these problems seem to have been resolved as far as I can tell so far.
So I can continue.
I installed a second homepage a few years ago. It is only the Bosch-Combi system from the late 50s until about the end of the 70s of the last century.
The address is: https://bosch-combi.de/
I have two of these lathes. Unfortunately, the cross slide was missing from the last machine I bought, which I reproduced from the original slide.
You can find more information on the page.

I will post some pictures here.

Is that your only lathe? ​

Looks great for everything you are doing the lathe

More than 20 years ago I planned to build a Quorn universal grinding machine. I asked a friend to get me some information and a price list. After successfully studying the price list, it disappeared into the back of a drawer. The price was beyond my budget at the time.
Many years later, I found plans by J.B.D. Willis on the Internet. He built his universal grinding machine ‘Bonelle’ according to the plans of the Quorn. These plans lay in a drawer for several years. At the beginning of 2007, these plans fell into my hands again and I told friends about my plans to build this machine.
I had some very good friends, who have unfortunately passed away in the meantime, who were very helpful in procuring the materials. One friend worked in the materials warehouse of a very well-known glass manufacturer. There he had access to a thick grey cast iron shaft lying in the scrap. He was able to cut out the necessary parts for me from this shaft. The other friend was able to get me chrome-plated shafts from hydraulic cylinders.
So I started work in August 2007.

Shortly before Christmas, the machine's shell was ready and the first grinding tasks could already be completed.
I had spent almost every spare minute in my workshop working on the ‘Bonelle’.

However, the machine was far from finished. Over the years, a few more accessories were added.
The machine was also treated with paint.
I got a lot of them from the book on the Quorn by Prof D.H. Chaddock.
More pictures will follow.

Hurrayaaa , I'm back.
After my password was reset, I was able to log in here with this name again.

The Bosch Combi machines are not my only lathes. I mainly work with my CT 920 from Taiwan. Occasionally I also use an Emco Unimat DB 200 for fine work. The two Bosch lathes are only shown at exhibitions.

I want to make one or these. Have any advice?

 

[Bruno]

Yes, make it yourself or buy it from the Chinaman. ;-))

What's the problem?
Start with the lower part, the dimensions are relatively unimportant. Then make the top to match. Then screw in the MT 2 cone and secure with Loctite 638. Place everything in the lathe and turn to zero position.
Unfortunately, I cannot provide you with any drawings for copyright reasons.

Good advice, have every intention of building it myself. Could save time by buying it, but where's the fun in that?
