After reading through all of the oil and radiator skid plate posts, it was time to replace the plastic oil plan flap and also protect the radiator. Mikes plates look awesome, but I wanted to try something myself. I have a front brush guard that I purchased a few months after I bought my TB and I have no idea of the manufacturer and I needed to work around that.
I bought a 2'x4' piece of 1/4" steel plate, 10' of 3/16" x 2" angle iron, some 5/16" bolts, washers and nuts and 2 stainless hex recess screws. About $120 total spent.
I do not have a welder, but I did all of this with a drill, grinder and portable band saw.
Started by mounting 42" piece of angle iron to front side of radiator bracket (the mount for my brush guard is c-chanell that is mounted inside of the radiator bracket)
you can see the angle iron through the tow hook opening
two 29" pieces of the angle iron bolted to the first one and to each other to step down and back (they form a W shape).
from top side
from bottom side
1/4" plate mounted to bottom piece of angle iron
plate cutout around the frame skids
the 4 original bolts used where the factory plastic skid plate was mounted.
Not too worried about the bolt heads getting mashed up as I am mostly trying to protect the vitals from small rocks, sticks, cornstalks etc.
I drilled a 1-1/2" hole for around the oil drain plug in the big plate, then made this little plate with the 2 counter sink stainless hex screws and drilled a 3/4" hole to give clearance to the drain bolt
I do not have the approach angle that most of you have because I am limited by my brush guard.
