I have a 6x18 Boyar-Schultz which is probably very similar to yours. It was in good but not new shape and was equipped with a good mag chuck. I paid a dealer $1500 for it about 1988.

If you want to quick test it's accuracy, place 4 small metal pieces on the corners of the chuck and grind them true. Flip them over and grind the bottoms true. Measure the thickness of the pieces with a tenth's reading mic. They should all be within 1/10 if the machine is good and your technique is proper.

The table lifts off and weighs about 75# . The basic machine weighs about

400#. You don't say which base you have. The sheet metal cabinet base is about 75#. I don't know how much the cast iron base weighs, but I would guess maybe 500#. The main machine just sits on the base and you would move it separately from the base. A knock-down engine hoist from your local tool rental house is recommended for easy and safe handling. There should be a heavy metal rod sticking out of each side of the machine casting near the bottom. Rig your lifting slings around them and the cross-feed hand wheel housing to give you a three point lift.

Spencer; I paid $1000 for mine with a good Walker mag chuck about 3 years ago. Current prices seem to be $1000- $1500 - often with no chuck. I have seen them as high as $2500. The two main things to look at are:

1. Listen to the spindle bearings. They should be quiet running and feel smooth when turned by hand.
2. Lift off the moving table. It slides on a flat and a V bed. The gear rack should still have well shaped teeth on it and no scoring on the bed. There is sort of a one shot lube filler at the front center of the table. This feeds lube to the bed ways - it should not be blocked up.

Mine has a sheet metal base which originally housed a built in dust collector. The grinder unbolts from this base with 4 bolts. My grinder has lifting handles on it (I also strapped around the spindle housing to help hold it upright). Do not try to lift by the very fragile shroud at the front of the grinder. Remove table when moving. I did all moving with a 2 ton engine hoist with no problems.

It's a nice little grider that uses standard 7" x 1 1/4" wheels. Jim

I heard this techhique isn't a good test. I believe the table can have a lot of wear in the middle and yet the corners will still produce 4 columns of equal height. So if you grind something flat is could still be concave. Seems to me that it would be better to grind something flat and then spot it against a surface plate to make sure its really flat.

One test I did with the help of Mike Henry. We ground a bar flat. Moved the bar to a surface plate and used a special insturment to measure the thickness. I don't remember the numbers but it was quite good. Maybe a variance of 50 micro inchs over 4 inchs.

Of course, there is the posibilty I have bad info and don't know what I'm talking about.

I have moved my 6 x 12 Boyar Schultz Challenger in a 2 wheel trailer. This is the unit with a cabinet base, not the cast iron base, and weighs about 750 lbs. Mine has the dust collector base, so add an additional 100 lbs or so.

I broke it down into 3 parts for the move. The table and chuck lifts off easily with two guys. Four bolts in the corners hold the machine to the base. I would guess the base is about 200-250 lbs. The main machine was moved with a sling under the studs on either side of the machine, and under the crossfeed handle housing. No real problem for

2 guys and an engine hoist.

Email if I can help.
