In the spirit of Lurk's topic working over his larger standards, here's another one for you guys!
With all the eventual scraping jobs I have on the to-do list, I have a number of straight edges on my want list, which include some long ones for checking mill table ways and lathe ways. I know there are ways to do them with shorter standards, but I'm a glutton for punishment.
SO, I found a 72" Brown and Sharpe at what I thought was a very resonable price, and shipping ended up being an even better deal, so here we go!
With packaging, it came in at 93 lbs. My young frame can move it around with little trouble, but holding it at a 45 to print a lathe's V-way will likely be difficult, so I plan on making a portable hoist that I can support it with.
It's pretty grimy but the face is in decent shape. I don't see any wear, damage, or excessive corrosion, and it looks like the most recent scraping was professionally done. I plan on eventually getting a larger granite plate at our shop which I'll be able to use to calibrate this, so in the mean time I'm going to give it a light stoning and trust that the surface is usable. While I'm cleaning it up, I plan to give it a new coat of paint too. I'm thinking grey with black lettering would do it well.
A few questions for you guys:
I plan on making a cart to store and transport my larger straight edges. I'm thinking a flat bottom cart long enough for an 96" straight edge (still on the want list), and 12" wide. I'd like to store them face down to protect them, but as the cart won't exactly be a flat surface (relatively), If I support the straight edges at 1/3 in from the ends, will that negate the possibility of them twisting or sagging?
And secondly, this straight edge is missing the wood block handles. I've seen a few style's of Brown and Sharpe handle's, but nothing resembling these. This has a flat plate with a stud bellow on either side. The stud's also give place for the straight edge to rest on 3 points when on it's side, but I wonder if you would use eye bolts to hold the handles on? With a straight edge this size, I'm less concerned with hand heat having a major effect on the repeat-ability of the face, but the handles would aid in moving it around and give place for it to rest upside-down.
Thirdly, I'd like to mount an ID plate on it to help reference any certifications. How much distortion could I cause by drilling a pair of 1/8" holes? Normally I'd rivet a tag on, but perhaps screws would introduce less stress?
I'd also be interested in any alternative methods of calibrating these larger straight edges, such as has been discussed in Lurk's thread as well as BrianB's thread on his large cast iron surface plate.
