Spray welding question

Hi guys,
I'm fishin here. Got a 1.5 inch punch press shaft chewed up .040" on the diameter. Is spray welding something I should try? I see kits for oxyacet which are around $400. We might do this once every 2 years. Any advice or experience with this is highly appreciated.
I'm thinking I don't want to TIG and filler it. I'd like it to be reasonably straight.
Thanks, and Keep 'em Flying !

Whether you spray weld or TIG weld it, it needs to be machined afterwards to turn the diameter back to spec. For spray welding, you need to be 100% certain of the base metal and application as not all powders are appropriate for all metals.

Thanks cj,
Yeah, I know. There's a MIG arc spray technique I found, but alas, I have no MIG. Just Oxy/Acy and a Tig box.
A buddy at work has a buddy... with a powder spray gizmo for oxy.
He's supposed to text me tonight.
Either way, it's one machine down and not an emergency, right now, anyway.
God I love what I do.
Got a bridge in Brooklyn if you believe that.
