Motorcycle tank
I'm in over my head right now. This is the shape I want to make. How would one divide this up for shaping? I have a stump and hammers and an english wheel. I can probably cobble together any other hand tools necessary. Any and all advice welcome.

Gas Tank
Looks cool! I'm not a pro at this but I guess I'd make the top one piece then each side separately and weld them on. Of course, this from a complete novice but it is a start.
I too am in the process of making a tank but mine is still in my head. On mine, I was actually thinking of making the inside first. Having that part fit the bike then work out. I guess I'm doing mine backwards because my bike has a lot of items on the frame that need to be avoided.

I'd make that in three. A top and two sides. Keep the top nice and wide so it has shape down the outer edges. That means you have less shape to put into the sides and where your welds go will have lots of shape too so it won't distort as much.
Alternatively you could make it in four with a spine down the centre and each half made of two pieces, that way you could get each side into the wheel to wash out the shape after welding then only have the central weld to sort by hand. You'd also not have as much to scrap if one piece got away from you. Either way will work and neither way is the 'right way' so crack on and good luck! Will

Hi Jeff
I am in the process of making a larger tank for my Norton in steel. I did post a thread a few months back in the motorcycle projects area. I too am fairly new to this. I started with the sides, which have the most shape. I used a stump to get the rough shape, then the wheel to get the walnuts out. The part taking most time is the underneath as it is a complex shape to clear parts on the frame. Picture below shows the top section. Tank top3.jpg Regards Dave

Jeff are you working with steel or aluminum?
If you are working with aluminum it must be thicker than with steel. If this is your first go at shaping then break your tank down into smaller sections and concentrate on producing that portion. Once you can produce that shape again exactly add the adjacent section. It's easy to get overwhelmed by trying to get too much movement in a single piece all at once. Jere
