DYMAG Refinishing, part II


This morning I headed back up to the Ye Ole Wheel Shop in Elkridge, Maryland to check the status of the Dymag wheels I had left for repair last month.



As mentioned in “part I”, the Dymags were victim of some previous improper wheel repair and needed some attention – there was also a weld in the one wheel that seemed to be about an inch or so long…



I was pleasantly surprised upon arrival of the progress made on the pair. The one wheel had been smoothed over and all previous “trash” used to fill & seal the inside of the rim was gone. As I mentioned before, the proper way to keep your Dy’s in good shape is to coat them inside & out whenever you refinish them, this is the way they came new. The other wheel, the one with the crack, had a lot of repair going on with it.



Although we are unsure why it had cracked, the materials used in the previous attempt to fix turned out to be magnesium. This is very good, as I was led to believe by the seller that it might have been aluminum. If any other materials had been used, the pocket of repair would have had to been completely cut out and new magnesium put in place. While still “fixable”, the end results would have been much more time consuming on a delicate wheel.



New magnesium was added, as that crack once uncovered tuned out to be about 5.5” long under the finish! The materials were added both front & back, then smoothed out. The wheel itself isn’t taking to the stripping process well - this wheel is a challenge. They tried blasting it with media and have now turned to a fine sanding grit.



Stay tuned as we follow along the process – I should have more on this in the coming weeks.

Hey Chris they look good so far. Very nice.
Pete - Thanks :m
I had brought my inspector but caught her sleeping on the job ;)

**Two key points about the task at hand that I cannot stress enough -
  • Magnesium CAN be welded & repaired
  • Wheels need to be finished inside & out or they will try to revert back to their natural state :eek
...stay tuned for more on this :v
 
Ye Ole News

Hey Chris, I called Ye Ole today and got bad news? They are really backed up, he quoted 6 weeks. He said 95 does NOT include center cap, AND he cannot do the center caps in that time frame waiting for a machine to do it (turning) and testing? John was who I talked to. WHOA, guess I will try locally huh? Also looks like the 285 F1 skids are on back order, YIKES
 
got the call today...

The wheel shop called to give me an update on the Dy's.

Looks like the epoxy on the one wheel was for more than a "pinhole" leak - it was a crack 3 inches long :eek

invisible to the naked eye, once under (air) pressure, the "test tire" lost air at a steady rate :(

The water placed on the rims surface pointed right back to that spot - So that was the bad news...


Good news, they will weld it & fix - I will keep everyone in the loop on the details...

If this works out, it could be a HUGE service to Callaway or any magnesium wheel owners out there as the myth has long been "un-repairable" :confused


...stay tuned :v

Part II.a.

A little progress has been made, they have gotten the wheels to the point that they are not leaking air anymore - a lot of welding has been going on :eek

The burn marks is actually scorched paint, nothing but a cosmetic thing ;)

Just a quick update - :v :m
