Samckitt, where did you get the engine model from? I could sure use one like it!

Grabcad.com.

Personally these cradles are cheap enough to buy vs build your own. For me, by the time I drive to the store buy steel/measure/cut/weld; it's far cheaper for me in terms of time/money invested to buy them from Summit/SDPC etc...sp

Now if someone has spare square tubing on hand, that's different.

Hey awesome drawings , see for me it's the opposite, being a fabricator I can whip one up quickly while my motor is away and have it here for when it's done . Now I'm also Canadian so they "cheap" units are almost double the original price by the time its bought ,exchange rate, shipped ,duty .

There is also something to say for the fun of building something vs buying. Just another chance to perfect welding, smoothing, and painting skills1

Exactly , ...maybe tweet things just a touch for how you want it eg I might make mine with some bolt on extensions for when the tranny is bolted up

I have a set of the stands with casters, and they work well. If you do something like the drawings above, I don't know that I would connect the 2 sides. Easier to install and store if the sides are separate in my opinion, also don't have to be as 'exact' with the measurements. Just my $0.02...

Agreed. I'd leave the two halves seperate. Much easier to store.
