Well I just pulled the trigger on a saw.
The small Craftsman/Atlas saws go for like 350-400 on Ebay
and most won't ship they're already on a stand with motor.
One was 350.00-no motor and 160.00 shipping. Thats insane.
I found this:https://www.kijiji.ca/v-power-tool/miss ... 1474201434
The vise opens to 7-1/2 inches has coolant, some sort of down feed control and cam operated blade lift.
Price was 220.00 CDN and about 250.00 shipping from Toronto to BC.

What a wonderful saw! I'd never seen a Shima before and it sure looks interesting. Some of us have an affection with "art deco" styling and this is the Japanese version-imho.

Yes. It has blade lift on the return stroke.
If you go back to link and look at the second last pic
the cam is on the end of the shaft almost straight up
from the red knob near the floor.
I found a youtube video of a Jet saw thats exactly
like this one and it shows the machine running with
a close up of the cam in action.

I bought a cheapo Chinese one; has coolant, has blade lift. Where it's weak is the clamp for the material, which is really poor.

Another problem is fluid running along the material being cut and then falling on the floor. I put a big plastic basin under it which helps.

Mine also had a leaky coolant pump that took a couple of tries to fix. It looks cheap but I didn't find any cheap coolant pumps so I repaired it.
First I just put in a new seal but that wasn't the problem; it was leaking through the case because the case is made of soft plastic that doesn't clamp together.
I added 2 steel collars to compress the soft plastic cases together, and 2 rigid plastic outer rings with long bolts outside of the steel ones. That works.

The blade lift is a self contained hydraulic pump/jack driven by a cam. That was leaky too, it just needed Orings.

I bought this saw because of it's location; there were better choices but I couldn't arrange transport at realistic cost.
I'm in Portugal and these were all in UK, so my logistics aren't easy.

The old blades make excellent knives and gasket scrapers!

Thanks for the pics and information about power hacksaws. I await a review of the "Shiva" once it's been with its new owner awhile.
Since my space was limited, I did find a few smaller type power hacksaws. I sold a couple but hung on with a Sears and a Jefferson.

At the beginning of this week, one of my work mates left
these on my shelf for me.
They're 17 inches 10 tpi. I should be able to cut them down
and put a new pin hole for 14 or 16 inches?

Yes, I am using 18" blades cut down to 17" on the Marvel. Cut to length with a cutoff wheel and drill the new hole with a carbide bit, or anneal a spot and drill or hot punch.

The old way was to have a dowel of Hard wood- I forget which type. It is clamped in the drill press and does remarkable heat to one spot. Flip blade over and go again. It is punched or drilled easier. Another thing about small power hacksaws is that their stroke is short in relation to the blade length. The fixed jaw will accept a proper size spacer to equalize teeth wear across the blade.

I went down town one day to buy a Right Hand brazed carbide lathe tool, and a 7x12" King bandsaw followed me home. The tool was about $7.. The saw was about $1100. Aside from complaints of some low blade quality, it is a great saw. When fabricating it is nice to make pieces fit.
