I've been wanting to do this for a long time. Deep down, this is probably the one project that made me buy my lathe. Up till now, I've been having to use a 1000lb trailer spindle and a piece of DOM tube with a plug welded sleeve in it as a bearing spacer for my bumper builds. I've seen a couple manufacturers that took it a step further by machining a thick wall DOM tube for the bearings and 1000lb spindle.. nice setup. However, I new the 1750lb spindle and bearing setup could be made to work for bumper use.. it just needed some "massaging". So, I turned the base down from 1.75" diameter to 1.50" diameter and then machine out a hunk of 2.75"x.500" wall DOM for the bearings to fit. Even got some 6061 billet aluminum to spin into caps. Just thought I'd post a few pics of what I've been up to so far this Winter.. 1750lb spindle next to a 1000lb spindle...  1750lb spindle and bearing setup... I love my lathe!  |

I think Eddie is building tire carriers that swing out for his bumpers. Very nice.

That's what it looks like to me... a spindle for a bumper-mounted-attached swing-out carrier assembly. Speaking of that, I'm debating on going that route with a "new" rear bumper or building a heavier-duty replacement for what I have now. Not sure I'll want to trust the mostly-aluminum stock carrier -- plus, I'll be needing to redo the spare tire mount after the axle swap anyhow. The hardest part of building a replacement for mine is fabbing the carrier mounts that bolt up to the body.
Anyhow, didn't mean to go somewhat off-tangent... looking good, Eddie!

call me stupid but what is it you are doing I am not understanding what the idea is Yeah.. this is the pivot system for tire carriers on rear bumpers. Most of the ones that are made use 1000lb trailer spindles or a metal rod with bronze bushings. Although those are pretty good systems, there have been reports of the 1000lb spindles breaking off at the base do to heat affected weakness and fatigue. Since I make/sell bumpers from time to time, that failure thing has me freaked out. Last thing I want is for one of my bumpers to drop a spare tire off the back of a vehicle moving 70 mph in traffic. So, being the "fix it before it breaks" kind of guy that I am.. I wanted a bigger spindle setup. I've had this idea stuck in my head for about 4 years now and just recently got the lathe which allowed me to spin it out. I'm obsessive like that.. ;D I'll post up a couple bumper pics off the one I'm starting to show how I use this thing.. |

Had it happen to me using a 1000lb spindle. Didn't drop the the tire off, but it broke loose swung out while I was making a turn. luckily didn't do much damage at all. Destroyed one of the spindle bearings at the same time. Good idea Eddie.

I'm building a bumper tire carrier for BOMLODER in March using the 1000 lbs. unit. It will have an integrated brace to eliminate breakage. (I wish I had a cool lathe!) Good stuff Eddie. ;D

I've already sold a couple on eBay.. but the smaller ones sell better. People don't want to spend the $$ for the big ones. That's okay though.. they're a good selling point in my bumpers.

Heck yeah! Those were huge compaired to the 1000. I think another good thing for the size is that they can take more heat while welding and wont get bridle as easy.
