Cool, the shop my Sense runs repairs Diamond Mining equipment and they have a similar automatic internal bore welder that actually more than paid for itself on the first job!

Imagine a $850,000.00US scoop tram (think low profile front end loader designed for underground mining) that the operator ran into a solid granite rock face at an angle, cracked both sides of the fork box frame that holds the bucket and bent the holes that hold the bucket bushings.  So, the manufacturer says for about $250,000.00 we can replace the front bucket-fork assembly, however, there will be about a 2 year wait for your order.  So, plan 'B', outsource to China, well they can make the same assy for about $160,000.00 BUT a 9 month wait (not including shipping costs and time), so the guys here said they'd do the job for $100,000.00 and in 3 months.  The job was actually complete in 6 weeks, 2 weeks to get the welder in and about 4 weeks to do the work!

Cheers,
Chazz

Hi Rob

looks like the welder is worth its weight in gold as they say, just  being able to make the repair quickly on site

just two questions

1 )  how do you re bore the hole  as in Chazz's example ?

2 ) do the make another version to rebuild damaged spindles ?

    for instance I'm thinking of the damage done by a failed roller/ needle  bearing  (the type runs directly  on  the spindle , with  no inner !)

    I  assume just adding metal fee hand with a mig welder would result in a bent spindle
