Nice, very nice indeed.
I don't think we have had a drawing posted as a pdf file before. Will you provide demensions later or do we just scale from this?
One thing I would change is your chamber. Do away with the howitzer sub chamber and make the vent come in at the top back of the chamber.
Hy DoubleD:
This is just the 2 principal views of the drawing which needs much more study & detail.
I have received other posts that are giving me some corrections which I'll include.
There are also a lot of small parts that need to be shown apart & in at least 3 views.
Once the drawing is proven I'll add all dimensions which will be in millimetres (Sorry), I just can't work in inches!
The advantage of PDF is that I'll plot the plans in exact 1/16 scale (In this case), so you can print it directly, having it scaled & can use the different views of parts as templates... (It works for me!)
Thanks a lot for your encouragement...
