Was wondering if any of you fellas would be kind enough to tell me what loader i have here.... Apologies in advance, i know this question gets asked frequently.
No, I guess it could be done but for a racing part? No. I feel it should be of the highest quality. Like aerospace/racing quality parts. Quality materials, quality machine work, fixtured and tig welded. I see no reason to mig it over tig. I really cant get past the size of the welds with the migged parts.Do you feel there is a problem with loaders being mig welded?
Looking for your honest opinion not starting shit.
Id really like to get together. Many of the failures this year (all mild steel parts) are at the edges of the welds and the mounting pad cant stay flat, it warps and wants to break. Keep in mind these parts had way too many laps on them and should have been replaced years before they did. Crazy amount of load on these things.I'll come by the shop sometime, I'll be needing your services this winter.
For what it's worth I completely agree with what you wrote. I've seen bad tig welds on loaders. In that case I'd rather it be migged. People want that spread out dime look on their welds... That just creates stress risers.
Hi Desertrat.Chris, Are your loaders all chromoly? 4130 or something different? Ive alot of guys with do a mix between chomoly and DOM. Whats your thoughts on material?
I've hung out with your pops at the river. I'll swing by.Id really like to get together.

Question for you...Youd rather mig weld chromoly or cold roll? Cold roll is flat out not cutting it in racing or fast lake use and the stainless is too prone to warping.
Alot of the sanctioning bodies including NHRA will not allow a mig welded chromoly cage or other parts on their race tracks.
Ahhhh water jet... The welders dream. No heat affected zone from cutting, no dross, just clean with acetone and weld er up. Water jet can be cheap Chris. The bigger the run the cheaper it is. I had pieces cut on my last boat and it's awesome. I'm pretty sure it was cut by desertrats famLazer is much cheaper. Problem with lazer is it leaves one helluva skin on the part where the lazer runs, even a carbide endmill cant handle it. Must grind the skin then machine. Id rather go waterjet, costs go way up though and there isnt much room for that. With all the deburring we do the skin comes off where it needs it and its all good. Things are working well up until this point.
The fixture is a 1.250 thick piece of blanchard ground steel, its serious. LOL.
Chris, see photos attached below. Is it aiming low? Uprights are exactly 3/16" thick. With my intake set flat with the delta, the biting edge of the loader is 9/16" below delta bad. Intake has been drilled and tapped to 5/16. (Im using G8 annodised bolts with washers/nuts on engine side.)Lee, mock it up and see where the loader aims, high center or low?
Very outdated design and its mig welded and mild steel. If the uprights are less than 3/16" thick don't even consider running that.
