New (to me) Boyar Schultz Six Twelve 2A

[Christianstark]

Hi all,

Picked up a new machine this past weekend. Anyone able to assist in any docs that may be relevant to this machine? It is set up for hydraulic table, but did not come with pump...so I will eventually like to sort that, but the machine can be used manually as well.

Any ideas on year of manufacture? I am in process of disassembly and cleaning. The chrome ways look fantastic, and the table ways look incredible for the machines age. Will send more pics on that.

I had found this:

This is what the hydraulic power unit for your machine looks like.
The pump is a Barnes unit, tank capacity looks to be about 2 gallons ( guess)

Very cool. I think I am going to have to build one myself, is it as simple as pump capacity and appropriate tank size? I have never dealt with hydraulic machinery. Does the pump always run, and inputs determine if the fluid engages a movement mechanism, or merely bypasses?

I have been breaking the machine down and cleaning, and inspecting. Spindle is crunchy but I THINK the bearings for it are very reasonable. I'm currently trying to remove the apron now. The hydraulics are making it a challenge.

The pdf linked by OTmachine gives details on operation.
If started in automatic the hydraulic power unit is started simultaneously with the spindle vs starting in manual which only starts the wheel.
More details in pdf.
1/4 HP at 1725 rpm 3 gallon reservoir that should have a max pressure around 250 psi.
There is a pressure line from the power unit and a return line to the power unit. They appear to be 3/8 hydraulic hose.
The valve that shuts off the motion appears to shunt the fluid back .
I did not see a pressure relief valve at the pump but I was leaving when I took the pics.

Typically a hydraulic reservoir is a minimum of three times the pump flow rate, hence the reason this machine has a 3 gallon tank and a .75 GPM pump. There are pumps on flyaway and Northern and, and look for 1.59 c.c. delivery and or .097 cu. In. Displacement.
Hydraulic pumps are generally run on 1725-1750 rpm Motors.
Don't go to far either way from the flow and pressure.

We had the same machine. Be careful when/if you take the control apart! Ours eventually leaked too much for our use and we removed the hydraulic system. Later we sold it off as scrap weight as the ways were totally wore out.

I had to take the control off the table in order to remove the table from the base. That was a messy PITA. I have it soaking in a simple green bath now and plan on giving it a scrub over the weekend.

Right now I am considering pressure washing the casting now that I have everything disassembled. Everything was FILTHY.

I frequently take machinery and a jug of simple green to the car wash.

Pressure washed. Did not plan on painting. I think I’m gonna roll with shabby and old.
