Straight edge castings for sale
Gentlemen (and others):
I have a few spare straight edge castings and am actively considering getting more cast.
There are 3 sizes: 650mm long I beam type, 1000mm long I beam type and a 630mm one with thick bottom flange that can be milled to a 45 deg angle for spotting dovetails. I made this one to check my Monarch CY cross slide.
Right now I have a spare 650mm one that has been planed on all sides and a 1m one planed on all sides that I'll sell immediately.
Prices are:
$200 for a raw 650mm casting, $300 for a planed one.
$300 for a raw 1m casting, $400 for a planed one.
$250 for a raw dovetail casting, $350 for a planed one. They require an extra setup to plane and time is money/aggravation. Also they cost more to get cast as there's more iron in them.
No reason why a 1m casting couldn't be cut into 2 smaller ones. I'll consider doing it if 2 people want say 450mm long ones.
All these castings were done in Hobart by Derwent Foundry and were left to cool slowly in the sand. I've found no hard spots in them and they scrape very nicely.They're reasonably flat off the planer but not perfect; well within the limits of scraping though. The planer is old and until I locate it where I want it to live long term I'm not taking a cut over its table to improve flatness.
In case anyone thinks of asking, no, I don't have and have no intention of making camelback types. I am considering making a pattern for a decent sized right angle square though. I only make patterns for stuff I personally need (want).
Prices not negotiable and do not include postage. I'm heading north in about 6 weeks, give or take, so can drop stuff off in Melbourne (possibly) and Sydney for sure.
I've had some inquiries from people who've seen mine and as I need to get 2 of the 650mm and 2 of the 1m ones done per pour (it's a matchplate pattern), I'm seeing if there's sufficient interest in bothering with another run.
I have one each of the I beam types available immediately left over from the last batch.

I will take a 650 as cast.

I'm surprised there is not a stampede on these things. Anyone that intends on rebuilding their mill or lathe should have one. I badgered PDW into doing the first run as I rather desperately need one for when I scrape the ways on my Deckel. I have 2x 1mtr and 2x 650's and 1x of the dovetail type from the first lot cast. I'm in for another 1mtr on the next lot so I can cut it in half and make a set of matched parallels for setups. It's the type of thing that when you need it you won't be able to just walk out and buy.
A bit of scraping practice on one of mine..

You could probably get them ground reasonably flat at quite a reasonable price as well.

Where would one find a grinder big enough?
"Bajool Cattle and Machine Tools" of course.

It's a real good idea to plane/mill them first though.
Ask variant22 how it goes trying to grind them even with a fancy computer controlled downfeed surface grinder....
OK I'll earmark 2 for guzzijohn. The patterns are now at the foundry, hopefully they'll pour sometime in the next 3 weeks. They're really busy and this isn't anything other than a nuisance for them so I have to wait, which means others have to wait....
I do have one planed 650 and a planed 1m SE in the shed ATM though so if there's any desperate hurry, not a problem. Planing the things takes more time than one might think, planers aren't fast. I don't have a mill big enough to do the 1m ones though.

I'm in no hurry so I'm happy to wait for the next pour if that suits.

I assume we will just get them all sent up together in the one lot to save on freight.
I am thinking of getting a face mill to fit to the spindle of the slideway grinder to take light 0.2mm cuts.Gold, the colour of choice for the discerning person.

OK I think a week is long enough for anyone who's interested to put up their hand so I'm closing the ad now.
Tally reads:
3 dovetail ones, one of those to a non-member.
2 of the 650 I beams, 1 planed, 1 unplaned.
2 of the 1m I beams planed.
I asked the foundry to do a pour off of the I beam patterns (4 at a time) and 3 dovetail castings. All are now allocated.
Might do some more in the future but there are no guarantees. Certainly wouldn't be before September/October.
For the Queenslanders I'm happy to drop them off at the e-go freight depot in Hobart or similar. Up to you guys to check prices - check ex Sydney also as I'm happy to carry them that far in my utility when I drive up in June.

What PDW is referring to is how I tried grinding one "as cast" without cleaning up on the mill or planer first. The outer layer ground OK but it sure did not sound nice. That tough outer layer is not all that friendly on my main "go-to" grinding wheel. Once that top layer was removed it was really nice to grind.
Fortunately for me my grinder is somewhat fancy (think 1998 fancy) and I just digitally tell it to take 2mm off as fast as it can and I walk off. Come back in an hour or so when I can no longer hear it. It usually ends in groans of "not flat", flip, flip, flip, swear, scrape.
Fortunately PDW has put mine on either his Vicky or his planer to get them mostly flat before I play with them. The Deckel has a measly 400mm of X, so not ideal! You can take the planed type and start scraping which is nice. No need for fluffing around with ear-muffs and two pairs of underpants waiting for the grinding wheel go let go...
Frankly I was surprised that PDW as offering to plane them. Having been there a few times when he is planing (usually my) SE's I can attest it takes a fair amount of time. Not a 5 minute job at all.
