What did you order that got that? I just ran a dummy order for DOM tubing and I see no added fees. In fact, on the last order I placed with them (some Delrin rod) the didn't even charge shipping.
I just did a test order for 5" od DOM tubing, 4" id. 12 pieces of 1" length. (Think 2-6-6-2 Mallet).
7.17 cost per inch
86.04 material cost
16.10 "PROCESS FEE"

That's the fee they add rather than call if a cutting fee, which is what it really is. I don't know where this fee kicks in, could be if you order 6 there is no process fee. But, at 12 there definitely is.

Sixteen bucks isn't too bad, when you consider the hassle of making that many cuts through thick tubing, oneself...

Here's a quote from Speedy Metals:
"Speedy MetalsĀ® custom cuts to any length and has NO CUTTING CHARGES and NO MINIMUMS!"

I say the "Process Fee" is a cutting charge. The first time I ordered a quantity of pipe slices there was no "Process Fee". The next time I tried to place an order I saw the "Process Fee" and ended up getting the parts locally and cheaper.

The fee is for taking the 12" piece fo tubing you ordered and which they would have cut off their piece of stock for you for free and cutting it up into 1" pieces. Seems reasonable to me. "No cutting charges" just means that when I order 10" of 2"x4" Durabar they don't hang on a $5.00 cutting fee after multiplying the price per inch by 10. It doesn't mean they will do my work for me at no charge. Some suppliers quote prices by the foot but add a cutting fee if your order is not a multiple of their stock size.

I'm still not sure whethers its worth the effort to try welding rolled flat bar.
Seems to be the cheap route here.

Anyone with poor experience in this forum on welded wheel tires?

I'd think it all depends on one's ability to create good welds. A seasoned weldor most likely wouldn't have any problems, and any dissimilarity in hardness/machinability could be eliminated by a full anneal after welding, which would also serve to eliminate internal stresses. A good and viable solution when tubing or pipe may not be at one's disposal.

I personally would stay away from welded pipe and/or welding up rolled flat bar for tires if you have the choice. There is always a spot where the weld was , that machines a little differently than the rest of the pipe . Even if the piece is annealed there is still a spot that is different due to the weld zone, and alloy of the filler rod used. Not saying you can't use welded, but I would go with rolled tube if given the option.

I agree, that joint will always be a weak point, and if that ever did break, it would be pretty embarrassing

I've never been able to find the weld in DOM tubing. It's resistance welded: no filler.

I have talked to the folks at Ajax rolled ring but never bought anything from them. They are now called Fomas Group. I know the tires that were made for the Southern 401 were rolled and machined at Ajax.

I was originally going to put tires on the greenbriar drivers but ended up having 16" round 2" thick drops burnt out of plate and machined them from there. Actually the guy that cut them out had hundreds if not thousands of round drops, he just found the ones closest to the size I wanted and recut to size.

This is their info,,

might be a bit much on shipping to germany though

One other possibility is cutting by water jet. For a few years now they can tilt the CNC nozzle to get a vertical wall in the cut on the side you want. If you have circles cut out of plate and they charge you for the blanks then by all means ask for and take the drops and outside residue. Your paid for it and it may come in handy later like for other wheels or.....

@Cary

I took the drops and outsides with me last time. The round drops are useful for smaller wheels; other live steamers might be interested in them too.
The odd shaped outside residues are less attractive. They are only useful after a lot of cutting, and for me the only working method to cut them is torch cutting by hand. 25mm thick steel with hand torch is slow.
I don't have a vertical bandsaw and my horizontal will only cut them after the parts got somewhat parallel.
