Machined 18" Iron Straight Edge/Prism/Parallel/Level. Featherweight Raw Casting

Description

18" Lightweight Cast Iron combination Straight Edge/Prism/Precision Level/Parallel.  No one else offers this robust and versatile design.These castings weigh about 14 pounds as cast and can be machined to about 10 pounds depending on the user's preference.   I carefully machine them and usually get the sole and face within .0015” of flat.  I also machine the top rail to within .0015 of parallel to the sole.
This tool was designed to accommodate a 20-arc second precise machinist level vial and mount mechanism made in the US by Geier and Bluhm.  Their part number is
4-3064-20. (Mounting the vial naturally requires some machining of the casting.)
The upper face is about 2.25" wide and the lower face is about 3" wide.  The top rail is about 2.5 inches above the lower face.  There is a finger recess provided to avoid scraping into a blind corner---this makes for easy scraping of the top face.  The angle between faces is about 45 degrees.
Dimensions:  17 3/4" L  2 1/2" H  3" W
Details of how I machine this tool are posted on PracticalMachinist website where a search on "machining a straight edge and dgfoster" will bring up the relevant thread.  I do offer machining services on this tool and, when I have them in stock, will list them on eBay as well.
This 18" straight edge has  a proven popular with machinists interested in leveling and reconditioning machine tool ways. (I have been selling these essentially by word of mouth til now to amateur and professional scrapers) uniquely designed lightweight rigid grey cast iron metrology tool.
I designed this straight edge and I personally cast each and every one in my own foundry using commercially sourced grey 40 cast iron feedstock.  Each casting is carefully inspected and hardness tested on calibrated industrial equipment to insure an excellent and uniform void-free scraping surface.  Every casting is properly thermally stress relieved prior to shipment.  The quality of these castings is second to none.  I guarantee it.
I usually ship within 1 working day of sale completion.  This casting is securely boxed and shipped USPS Priority in the continental US, Alaska, HI, and Puerto Rico.  Shipping takes between 1 and 3 days via USPS Priority within those areas.  UPS is a little slower.
Casting are supplied either as raw castings or machined.  Raw castings have had gates and risers cut off and parting lines coarsely smoothed and any flash knocked off but are otherwise as the come from the mold.  Photos show a typical Featherweight casting of the type listed.
Local pickup is ideal, but if castings have to be shipped they are securely boxed in a fitted wood box.   I have straight edges currently in stock ready to ship.
If you have any questions please contact me for clarification.
These casting are not machined nor are they precision scraped.  You can buy one and have it machined and then scrape it.  I do provide a very economical machining (but not scraping service) if so desired.
I Usually ship within one day of completion of sale.
