my tow bar mounting idea.....

[json3904]

i will be trying to mount my tow bar to the pathy this weekend and i was wondering what yall think about this idea???? it will be removable so when i get to the park i can take it off and put the hook back on......

 

 

i just noticed the bracket isnt to scale it is actually 1/4" thick..... we couldnt find any place to weld it directly to the frame, so we came up with this idea.....

no ideas???????

Tow bar? What do you mean, like to pull it behind another vehicle?

Tow hitch? As in, you already have a reciever hitch installed or what? Front or rear? Who? Where? When? Why? heh

So, where are you mounting the bracket on the Pathy? You might look into bolting them into the factory tow hook mounts under the front of the frame.

that should work fine...but I would cut a chamfer on the piece that will mount to the stock hook locations so the front block is perpendicular to the ground using both bolts on both sides should be more than enough to handle the shear from pulling the pathy behind the X (without running the #'s)

 

I did a quick google search and this is a quick introduction to figuring your bolt size requirements. The application of the bolts are in single shear which They discuss...I skimmed it and it seems to be a pretty valid (I know they used Sigma=P/A but wrote it funny)

I guess I should have mentioned that you want to take and multiply the weight of the pathy times 3 or 4 (this would be a sudden stop loading) and then divide that by 4 for the 4 bolts and take the individual bolt load and do P(this is your load) divided by the area of the bolts cross section (i think those are 1/2" bolts down there)

 

once you get your answer you want to divide the bolts allowable by the number you got and you should be greater than 1.5 (that would be your safety factor) but I may have gotten that backwards b/c i've been doing the margin of safety for aerospace and its a lil bit different so you may want to research that and check that I'm not telling you wrong

Not speciffically, but yes he did mention putting a hook back.
