Looking forward to seeing it in action!

I love watching my Marvel cut.  Sometimes I just put scrap in it to watch the action, but don't tell anyone...

Watch it Russ will have you standing in a corner!!!!

Anyway........back to the real thread.
Working on the sawing action for the saw.
What you can not see is the eccentric (on the backside) for the saw.



Now I am in a conundrum about the size(s) on this machine.
I was lucky enough to get links to patent drawings of the actual machine.
So I went here;
http://ia700802.us.archive.org/16/items/cihm_50672/cihm_50672.pdf
And printed out page 11.
A very elegant piece of equipment.
Wonderful specifications but....
When i print out the page the pulley scales out to 14" the sawblade 17" (matching the specs)
but nothing else matches.
"height of work table" says 21" not when the blade and pulley scale out correctly, it is 30"
Overall height says 3' 4" but I get 4'!
I did a cardboard mock up of the base (based on the CHB dimensions) and the machine looks diminutive compared to the others. It almost looks like the wrong scale!
May be i am not used to how BIG the other machines really are.

Anyway all things considered I think I will build the table height at 30" not 21" as listed.
Also looking at the CHB machine it is much wider/squat that the patent images.
I guess like everything the equipment evolved over time...........

The few i have seen actual pictures of were secured to chunks of timber so i will also do that.
What do you guys think?
21" or 31"

How about 30", Marty?

I was trying to remember how high our power hacksaw was when I was a machinist. I want to say .. "knee high". I would say the larger pieces sawed the lower it needs to be. If you are using a crane to move a thousand pounds of steel bar to be sawed it needs to be low. JMO. Anyway .. by accident I ran across this .. thought it interesting. Homemade Power Hacksaw

I go with Ed.  I think it should be low to the floor.  Like what you have done so far.
