    I went down to work on my Bentley BR2, but discovered I need more supplies to continue along..So I thought this may be a good time to start another project, and keep the interest up..I have the casting set for the Gipsy Major in 1/3 scale and have been wanting to give that a go..
    So now I start..When I received the castings, I looked them over carefully ands they seemed to be decent castings, except for the oil pan, which seemed a little out of shape..These castings do not have a whole lot of extra metal on them, and I was worried that the oil pan flange may not work out, because it had a twist in it and also the flange on one side had a belly in it going towards the bottom of the pan..I did some filing on it and tried to set it on blocks and get some measurements, and to get it to cut evenly all the way around, one corner would end up thinner than the rest, and there is not a lot of metal to start with..I tried to get the twist out, but was afraid I would do damage to the flange being so thin, so I went ahead and started to machine it..It did end up that the one front corner is thinner than the rest, but would not be a problem, and I believe when I do the finishing of the pan to match up to the block in width, it will be OK as it is a little wider than the block...
    Next I went on to the block, and that one was great, being able to finish the flange with very little metal removal..Again, I must mention that there is not a lot of excess material there..I will be able to finish it to the specs on the drawings, which are metric by the way,which means I have to convert everything having all imperial tools...………
    This engine was an original design by Reinhold Krieger of Germany, and I have included a picture of his engine to show what it looks like and also to show his incredible work..The first time I saw this engine I knew it would be a project that I had to do...I found out that Engineers Emporium in the UK now has the castings, and I ordered them...…

    Hello,
    Very nice work..I just ordered some metal for mine..Did you have a problem with your oil pan..One corner of mine was thinner and there was a belly and warp in it...I am not that far ahead because I am working on the BR2 also, and my ambition level has dropped some.....

    Hi,
    No casting problems. I buy it directly by Reinhold in Germany. It was the last kit (only 10 made!!!)
    But, I'm busy with the Lanz HP. After this, I will back on the Gipsy.
    The BR2 is also in my desk....
    From april, I will have much more free-time, and of course more time for my hobby
    regards

    Hello,
    Thanks for the info..When you have time, could you post a picture of your block and oil pan..I would just like to see if any difference...Mine seems to be a very coarse sand casting....

    Hello,
    Thank you for that..From what I am seeing, your castings look a lot better than mine..
