Hello all,
I just picked up a 1980 Grob 4V-18 via auction. I was unable to inspect it so took the gamble. Was able to start it up for a few seconds when I picked it up to confirm the thing ran at least.
The good:
The bad:
The ugly:
So, I have three questions:
1) Is the lower wheel salvagable with a new tire? It feels like the majority of the crown is still there, and I'm home a new tire will at least get it to servicable condition. This is for my personal shop, so won't be run 8 hrs a day, so I'd prefer not to spend $500 for a new wheel if I can avoid it. Plan is to use the factory rubber tires unless someone makes a case for urethane being the greatest thing ever.
2) As I'm missing the upper guide holder, I can either buy a new factory one and a new set of guides, or for almost the same money get a set of Carter roller guides. Does anyone have experience with these on a Grob saw?
3) Can someone confirm this is the correct lower guide holder? It looks to match the images Grob has as best I can tell.
Hopefully in the next few days I'll be able to rewire it to 230V and clean it up, change out the gearbox oil and make sure all else is good.
Thanks,
Joel

The good:
- Seems to be in decent overall shape
- Opened the back cabinet and found both the rip fence (thought it was missing) and a circle cutter attachment
- Turns on at least
- 7.5 KVa transformer attached that I don't need and can use elsewhere (machine currently wired 460V)
The bad:
- The upper guide is some sort of homemade ball bearing setup (machining not up to a commercial piece)
- Lower guides missing, holder worn badly (luckily, newer holder in cabinet)
- Some random color repaint (paint job in the future to factory green)
- Rip fence guide in the front is bent, I'll need to straighten it or make a new one.
The ugly:
- Lower tire missing altogether, wheel has some damage on it.
