Torklift Cannon

I build that almost 2 years ago.
Cost of 48" of 3" tubing about $40, including cutting.
Shall I sue for copyrights?

Too bad it's only 3600/360 and without WD for the 36".

That was my plan, but after taking a good close look at the factory receiver hitch, I wasn't confident that it was robust enough for 7,000 lbs on a 4' extension. 7,000 lbs on 2' or 3,500 lbs on 4' seemed OK. It cost a lot more to go with the 30k lb Torklift receiver, but I'm glad I did.

You might not like the result if you tried. Torklift probably prototyped something similar years ago. :D

I did some calculations and assuming older TL stinger was 2.5" tubing with 1/4" walls combined with 2" solid bar, the 3" tubing with 1/4" wall comes well stronger.
In construction it it cross section height what give it main strength.
Than my boat is less than 3000 lb with minimal tongue weight.
I am not worry.
Besides... I tested my receiver/stinger pretty good

I'm with you, I always prefer to fab things myself and as far as TL having a copyright/ patent, I doubt it. TL is not the only game in town, by a long shot.

Nice, I wonder how soon they will be available.

Interesting that the ratings are so different from what Curt offers

Curt
41" 5000 wd 7500
48" 4000 wd 6000

Torklift
42 3300 wd 6600
48 3000 wd 6000

Torklift's ratings are based on using the Ford OEM receiver. It may be a limitation of the receiver with that much leverage. Even if you fabricate your own, you now have a ballpark figure of what a single truss extension can safely handle.
