Stand is looking nice. You'll definitely have to post a picture once you get it finished. I have limited carpentry skills so I really respect those that have the skills and tools to put together a finished stand.As far as only supporting the front and rear parts of the frame, it may work but I would prefer to have the entire frame supported. It would bother me too much worrying about it.
Why would you choose not to fully support the frame anyhow??
Bump: Here is a picture of the stand I build two weeks ago.... Oddly enough it looks very similar to the thread you linked. I didn't use any plans for it, just designed it to fit my application. It will be clad in solid maple, the trim and cabinet doors are finished I just need to stain and seal everything. I will start a tank thread soon.
Here is the 40B stand I have now built two identical
Shims ought to cover that slope , I put shims every 6" the whole way around stand, level or not, to keep it off the floor directly.
@Doc7 aren't those clamps from harbor freight such a great deal??? Normally I splurge on really nice tools (over $6k in tools) but those clamps are pretty nice and soooooo cheap. If I remember correctly like $2.99 or $3.99.
Being as you are in St. Louis area I could probably build you a steel stand that would be nearly indestructible, would support the weigh easily, and have adjustable legs. Down side would be the cost of the steel, the bulkyness of the assembly for transport and the fact that steel is ugly
