Camel back etc
« on: October 08, 2018, 03:36:20 PM »
Why are camel backs and straight edges sooooo freaking expensive?? Even unmachined ones.
Is cast iron alone that expensive? Or is it because it's specialty and sellers know what they can get...
Reading Connelly's book is turning frustrating because of all the instruments and equipment I now want to make the job easier and better...

They are very stabilized cast iron.  Other words, they have been theromo-stress relieved to a degree that leaves the iron very stable during use with much distortion.

People that have them for sale that build them are not making that much profit from one.  It's the time and labor that goes into making them one at a time.  They are not mass produced.

Seems the best I can hope for is just a length of cast crap I'll shape into a straight edge bar to spot my lathe and milling machine. Much the same as I did recently for the compound.

If it helps any, I don't have one either.  I did make one from a piece of Durabar that is three foot long and about 1-1/2 wide by about 4-1/2 tall.  If interested, I can post the drawing I used to make it.  I actually farmed it out to a local shop that I worked close with on my customers projects a few years ago.  So far it still stable. The piece of material had sat out side in the sun down here for over ten years, well seasoned in my book!

I bought from my FIL an Atlas 12x36 lathe, the bed was chipped in 3 or places, so I called Clausing, to as about casting numbers for a longer bed, to get the right one for my lathe. The guy gave me the information, but also said they had beds, ground and packed ready to go. So I ordered one, when I got it, it was in a crate, according to the slip inside the crate, the casting date was 1964, the grinding date was 1966 and the final inspection date was mid 1967, reinspected in 2005, 5 days before I got it. So if the paperwork was to be believed, it sat in that crate for about 37-38 years, kinda aged.

The extension table on that saw would make a nice light weight surface plate. ;)

I was more so thinking cutting it into a straight edge. I suppose it depends on how thick it is, how many ribs, the ends of the table should be relatively thick.

Your going to find that the table top is very thin.  Once you start cutting on that, it's going to warp in all sorts of directions.  It's going to be more troubles that it's worth in the long run. I'd Keep looking for something else.
