Mike,
Nice work.
I pride myself as being a reasonably good welder, but I just don't have the time to fabricate from scratch a toothbar for the price Markham can deliver one to me. I purchased a Markham toothbar and I am not sorry, in fact, I am impressed by the quality of their product. But it looks like you have done at least a comparable job!.
Again, NICE WORK!!!
Gary
