that'll work just nicely. its even a little fancy

Here is a picture of my roller holder, holding a Sixty roller.

That's a neat rig there Ken

all great info. what I will say is one should look into mig welding vers using stick. I love to run rod but mig is about 300% faster in lb per hour of weld, faster travel speed means less heat input into your workpiece but you can make a mess in a hurry if you're not careful. I would say 7018 or even 7024"jet rod" all your trying to do is get lb of metal onto the roller I would say you're wasting your time 6010.

On Mig Vs Arc. I did a bit of build up on my D9 Sprocket a few weeks ago. Used the Mig with a wire called Talarc HF350 which was recommended by the welding guru. I put about 15-17kg of wire over a week or so. While you could really get up and into it once you got the hang of it, my little 250a mig didn't really have the required duty cycle to take full advantage of it. Plus, even though we cleaned it back to shiny with a flap disk and washed it with prepsol, there was a lot of contamination. I guess from however many years of use and grinding whatever into the steel.

I can't Arc weld to save my life, but my welder mate finished the last 3 or 4 teeth for me and claimed he'd rather do the job with the ARC due to the contamination.

agree Mig would be many times faster and less heat imput for the metal moved to the roller or work piece etc....

-but if Stick is your only option, then yes 7018 (Liquid Air) would be the way to fly, its really smooth and easy to apply..

HI! I went the around and around method. I can adjust the speed that the holder moves to meet the speed that I would like to lay the bead down at, I also have a foot switch to turn it on and off with when needed.. I would clean the surface that I was going to build up by sand blasting, mount the roller in the machine and then preheat it to the recommended level. I would then lay in one bead around the circumference, chip the slag, and wire brush it with an angle grinder. I would then check the temp again. Usually I had to hurry a little with the clean up between passes to keep the temp up to the minimum recommended levels. I rejected a couple of rollers after welding as I found what I thought was some cracking in the web of the flange but I had not checked them closely before welding them. Other than that no problems with this batch but they are still waiting reassembly. The friend who I copied the turner from has put many hours on circumference, stick welded rollers.
