looking good. I say you coat this with some seriously strong stuff. Not paint, spray on bed protector or something...?

Top sleeves that will mount to the I-beam are cut out and drilled for 3/4" mounting hardware. Now I need to make a plate that will weld to this to bolt to the I- beam. Maybe more to see tomorrow...

Oh - I've really been enjoying Keith Fenner's videos on YT. I watched all 7 episodes of the dragbike rear hub rebuild. He does some very impressive work. I only have about another 250 or so to watch.

Thanks! I picked up some machinery grey gloss enamel. I like how jgrady's bridgeport base turned out, and picked up some paint last week at the hardware store. It's gonna' take a truckload of degreaser to cut this oil from drilling.

What I love about them is that no matter the project, there is always something to learn.

And the Lincoln books are great. They are all projects that someone has constructed. Lots of interesting and useful stuff.

And sorry Zombie_Stomp, but they are all still in print and copyrighted material, so I can't just copy stuff out - it's an ADV thing, respecting intellectual property, and all like that.

Check with your accountant. Workshop equipment might qualify as an education expense/investment.

Partially a money issue, partially 'I know I can do a really good job on those'.
Fun! That looks like some goodies from the CNCzone.com Electronics forum and Machine Controllers Software and Solutions forum.

I've been looking at crane pieces and parts on CL. Then I stumbled across this. http://www.dearborncrane.com/pdf/gantry/gantrybro.pdf while reading a thread here http://www.practicalmachinist.com/vb...78/index2.html

Interesting....according to coffing's chart, the spans that dearborn is talking about are at a less than standard 5:1 safety margin. They are showing an almost 11' span with a narrow flange (3.33") S6 I-beam. (I've learned a lot in 2 weeks! )

Dearborn's adjustment pins appear to be identical to what I picked up at Kirk Supply. I mean Tractor supply, and they only use one. So maybe I'm good to go on what I'm building. I'm still cooking up the beam/top sleeve mount in my mind. Gotta do some scrounging today. I want a longer plate (14" or so) for the beam to rest on so I can gussett to the top collar for extra support.

I may also upgrade the thickness I cut the caster plates from...

That way, if I ever decide on a larger beam and hoist to carry 2 tons, the legs should be plenty stout to handle the job.

Coffee break over - get back to it, slacker.
couldn't you have drilled thes @ 6" o.c. and still get the same amount of height adustment since your stand is drilled 3" o.c.?

Precisely. I was already 1/4 of the way complete when the brain fart was realized.

Nice find! I like how they clamp the posts to the beam. Looks like I should have turned my adjustment holes 90 degrees to be free of the come-along. Live and learn.

Mine won't be so easy to put together. Heheheh. But, I will do it by myself with a chainfall and some help from the rear deck.

Taking more bites out of the project after work...



I get my hands on some scrap 6" channel. It's galvanized, but beggars can't be choosers. I will grind off the zinc before welding. This should be a very strong beam support that I can gussett to.



Once again, I see that the holes should have been turned 90 degrees. This isn't quite how I planned on doing the gussetts. These are merely scrap pieces from the legs. This would work, just not how I pictured it... I wanted the gussetts boxed, not open. I could still do that if I welded the nuts to the sleeve...



I'm seriously considering drilling another series of holes here on the side, 4" o.c, so I can rotate the post and make everything good. It would also solve the come-along / adjustment pin clearance issue. I just really don't want to drill another 16 holes.

I'm starting to get a little unhappy with myself that I missed this. Now's a good stopping point for tonight. I need to think about what I want to do next.

Until next time...

Or, you could cut the supports loose and weld them back again to the sides. It would be a PITA, but you wouldn't have to drill new holes, or have two sets.

Just thinking out loud.
