Trying to make heavy duty casters.

Not that I don't have enough irons in the fire, but I wanted to test the ForceCut and drill some holes in some 1.5 inch disks I have. Then run a pipe through the middle for an axel, mount to some angle Iron, and make casters for my little bench as it weighs around 500 lbs. The ForceCut set at 70 and 75 PSI, and my unsteady hand cut this hole. I am thinking about just welding some 3/4 inch pipe to the ends since the hole leave much to be desired. I was really just seeing if I could cut over an inch, and it looks like I can. Now to start lifting weights so I can keep the torch steady;)

Looks like you are working with cast iron, if so you will need to weld with some nickle welding rod.

Keith I think it is cast iron with threaded inconel inserts TIG welded in the middle. The inserts ate one $25 dollar drill bit (with Drill speed way too fast), so I wondered if I could soften it up a little with the plasma cutter.

Heat it up to Cherry red and let it cool slowly. The plasma cutter(pilot arc) will heat it up, but it will probably cost a set of consumables.

inconel is a soft metal that is easily machined... more than likely, it is manganese based especially if it is an old axle plate. manganese work hardens alot like stainless and the hotter you make it, the harder it gets as well, when you try to drill holes, it "grows" pinching the drill bit, creating even more heat thus a vicious cycle... i have found a set of drills that excel at drilling SS, manganese, cast steels and irons VERY well, but dont do so hot on aluminum or wood. the bits are made by Irwin and called turbo-max. costly, but effective, and you GOTTA drill slow and you cant drill pilot holes... basically, if ya want a 1/2 hole, start with a 1/2 bit... lemme find a link for the drills...

that isnt the only place that carries them, nor is that the only sizes, just a point of reference

SicFabrications, thanks. I love stainless when I'm done, but hate it when I'm working it and don't want to admit how many drill and mill bits I've killed. I am only starting to realize that the heat is what is killing me and dulling my bits. One future project is to convert my Hummer H1 Kit over from steel parts to stainless parts as I hate rust. I am going to give these a spin as I only have one 5/16 bit left. I have so many broken drill bits, that I once cut an entire Suburban body into little pieces using my old Lincoln Ideal arc and old drill bits as a spark cutter. The drill kit price seems reasonable enough if I can't kill them;)
Thanks
Iggy

15 piece set only $13.47 @ Lowes. You call less than a buck a bit costly? Guy at Lowes "What's that sqeeking sound?" Sales man "Oh that's just the hinges on Stans wallet"

I just purchased two sets of the drills , now to find some inexpensive heavy duty casters. This is one reason a foundry and some wooden boxes with baked river silt would be nice. I could just copy some that I already have.

I don't think that is is Stan's wallet, I think it is his VAULT!
