So I've been looking for a good, used, reasonably priced cab machine for a while, and I rarely see anything in the Southeast. I've got a line on this one, a few hours away.  It's an 8 inch machine, a Crafttool (Sears) which I believe may have been made by HP. The seller says that the 3 wheels are excellent, and he thinks they are Crystallite. As you can see, it's also got an expanding drum and a saw. It comes with 2 motors and the cabinet (stand). Seller is asking $600. Worth it? He's also got 6" Covington that I'm waiting on pics of, a pixie (too small for me) and a 16" HP saw, which he'd like $750 for. Maybe he'll work me a deal for a machine and the slab saw. Any of you equipment experts have any advice? |

600 a bit steep
of coarse that depending om
just much life is in the wheels
ask that seller if the wheels have been off the arbor recently
that can a tough nut to break
if not so
does look like its been well kept
best

If I needed a unit and didn't mind the drive, I would buy it even if the wheels are shot but can easily be removed. I would remove one of the hard wheels and replace with a 220/280 soft. A new Latvian or Jadecarver wheel in 80 or 220 would be around $100 delivered. A 220 soft from Johnsonbrothers would be about the same. If the unit is in good working order and since lapidary equipment is scarce you could upgrade and sell it later.

Right on
I keep looking at that beasty
If those wheels and the expando are really decent
that may be a good deal
If the machine itself is as well maintained
Maybe its even a really good deal
Investment in 8” wheels are expensive
And those expando’s are pricey
I bought my Lortone 8" arbor
15 years ago for 250.00
sans motor
(those are a dime a dozen mostly )
that Lortone still hums
So the wheels are where the expense comes in
And a 8” arbor is the way to go
Because then you have the option to
use 4” and 6” wheels also
o yeah my Lortone doesn't have the saw attachment
so that a bonus on that machine
Do you have space for that beastie?
Why is the Pixie to small for ya ?

Wheels were expensive. The list on a DP 80 grit 8 inch wheel is around $300 and can be purchased on ebay for about $200 delivered. I've been buying wheels for 15 years and an 8 inch plastic core jadecarver wheel is good or better than DP. The Lithuanian top wheels are excellent. I have only bought the 6 inch. They are aggressive and cut as least as fast as 8 inch DP.

Could be a good deal if in good running order. Is he selling the Alumacraft boat too?

Looks like an original configuration, but I'm puzzled by the expando drum spraying water at the back of the switches, and blocking access. the Tray also doesn't look to cover that drum? Maybe the switches were supposed to be elsewhere and that part of the tray slid over the right (looks) like an indent for the belt for a motor? ALso doesn't look like a belt will slide off that drum easily to the left.
'two motors' and two switches and it doesn't look like the shaft drives the trim saw. I take that as a plus, imagine they're separate units. Usually saws/drums are better at different speeds and you're never using both at the same time. Wheel condition, bearings, etc, not a steal, but good if it's all working ok...

It looks to me like the tray under the expando is backwards, then the switches could maybe be moved to under the saw table and out of the wet.

FYI keep in mind that Sears sold so lapidary hardware up until the late 60s. My guess is that the unit shown is from the 50s. A lot of that vintage did not have sealed bearings. Be sure to check the bearings. the big money there is in the 3 diamond wheels if they are in good condition.

I'll check the bearings, but do I just need to make sure they turn freely and don't have any slop side to side? How hard and expensive is it to replace them if needed? The seller has a covington unit that I'd consider too, and I think he's got a used Genie coming this week that will be available. Maybe one of those would be a better fit for me? I liked the idea of the 8" unit though, since that's what I used at the club. |

There may be those on here that can id off the shelf parts for vintage HW. I am not that guy. Thou w.w.Grainger was used by spartan Mfg on their lapidary slab saws. |

I like the room of the 8" units but a reasonably priced Genie would be hard to beat and Covington makes sturdy HW

No, waiting to see what else comes up. The guy said he’s have some more options soon, plus, I had to stop telecommuting and return to work... so my schedule got a lot busier!

It may be too late for the initial machine, but I would not be afraid of it.
The suspect expando near the switches may have initially been a site for a buffer. My similar HP machine had such an arrangement. I modified the pan underneath and it now houses an 80 grit wheel.
The idea of having the saw run off of a different motor than the arbor is also a great advantage. Saw does not have to run when polishing and no clutches involved as in some HP machines. My unit is similar. There is probably (depending on your preference) for a 4th wheel in the main gang area as well as a nub of the shaft for a buffer on the end.
Wheels and bearings can be replaced as long as the rest of the structure is good (mountings, trays, main abor shaft).
Most machine of this age are still wearing the old sic wheels that you know you will replace, if this one has some diamond so much the better. There's always the possibility of a better bargain, but if you see something that you want within your price range, its better to buy it than to wait months or ??

Thoughts? |
