I get the idea Baz been thinking on it myself some before this, might have posted things, not sure.
"i don't really get the idea ,even if the oven is modular you still need the space .
if you hve a 6x6x6 modular oven or a 6x6x6 non modular oven once assembled
they both need 6x6x6 space "
While that is true, think of a 20'X8'x5' oven and space. Along the back of a shop wall?
In 20' wide I can store 3 cars side by side, each 6' wide. So if I need a 4' long oven I roll out 1 car and have room for 6' or a bit more. If I need a 7-12' oven I roll out 2 cars and set up the oven.
Rarely I would need a 20' wide oven, but for a truck/van frame I might, so just roll out 3 cars and I got my 20' wide space. In most cases a 4' wide oven will probably do, so make the main permanent space to fit the 4' oven and when needed roll the cars outside to make more space, hopefully not in bad weather LOL.
In real shop case, I would hope to just compromise my storage and work space, instead of 2' clear all the way around 2 different cars end to end, push them bumper to bumper, no work area left but it's only while baking one frame or so and not that big a problem when rarely needed. Tear down the oven and roll back the cars and have the normal work area for them again.
My Problem is not space, it's money. I got more land than I need for cars, but not enough money to build a large enough shop for the cars I have! And I buy more cars all the time
Maybe if I stopped buying cars I could save the money to build the shop. But the only fun I ever have now is when I buy another car.
Maybe I should just scrap all the cars and get a new girl friend
She would probably cost me less money in the long run LOL.
