nice work buddy, looking forward to seeing the rest of the build
My design is a little different than yours. You have a spreader type wedge welded to you hbeam on the top flange and than another post mounted on the end of you hbeam that you wings are mounted on. My wedge is a straight piece of 3/4 flat plate that does pass thru the hbeam, but is not welded to the hbeam. My wings are welded to that same piece of plate. Where are design is similar is that I attached another piece of 3/4plate to the end of the hbeam. I used more plate that I ran down the web and on each side of the upright plate to keep it from breaking it off under pressure. My wedge is lifted up and down from the bottom using a hydraulic cylinder and the plate i welded to the end of the hbeam is the support that is pushed against. At one time I had a picture posted, but I guess it got lost with everybodies elses
I really thought what I built was overkill, but doing 6way splits, Its barely adequant. Most splits it works fine, but get one of those large dia rounds with a couple of knots and it will make you wince watching the beam flex. It hasnt bent yet, and nothing has broke, but you know in your gut its only a matter of time.
You will noticed i also plated the top flange of the hbeam where the pusher slides. I used 1/2in plate for this. I think you might also consider this type of plateing to prevent the flanges of your hbeam bending. I have seen several splitters that use gussets between the web and flange for the same purpose and this seems to work well also. I guess since you are still in the building process, I think I would try to incorporate the extra plate as well as the gussets. You might not need it, but it easier to do now than have to do later.

Nathon I too am a Hypertherm fan I am running the Powermax 105 480/3 phase. Sweet machine.
I think that you said you ran wedge thru beam whats your opinion on mine. I am at a point where I can plate the wedge slide post and move forward or cut wedge off machine up a new one run it thru the beam and move forward.
I am 50/50. I feel that with the two tied together at the top I should be fine.
Throw out your thoughts which ever way it is getting done today. LOL

Eric, I think your main wedge will be fine, The way you mounted the center blade and then welded the spreaders, they should act as gussets. I think notching the flange and dropping the wedge into the beam would have been better, but i would only change it now if it makes you feel better. Most of the pressure on your beam is going to be in your additional 6way. If you plate the wedge slide post and run the plateing far enough up the web of the beam to distribute the load, and then tie it together at the top of the main wedge, It should do the job. While i do still see a lot of flex in my beam, My wedge is 25in tall fully extended, thats about 10inches taller than what you have planned

i didnt run mine through the beam, i just suggested it to you since youre wedge isnt very deep, but tall enough to have enough leverage to tear the base material (beam)
mines 11" deep x 14" tall it gives me plenty of area to weld to, heres mine...
on my cylinder mount i did run my plates through the top flange all the way to the bottom flange, because it was only 3/4 x 8 material, probably wayy overkill but its better than not being strong enough...
another pic of plate before boxing the hbeam. and a pic of my pusher plate, it is 17inches tall made with 1in plate I dont have a pic of the rear cylinder mount, but if you look at the hbeam under my cylinder, you can see the end of the plateing I did to re-enforce the mount. My hbeam was actually to short to begin with so my cyl mount is added to the end of the hbeam and not to the top. It is mounted the same as my wedge backing plate, welded to the end of hbeam and sanwiched between 3/4in plate

Going back together I welded 4/6 way slide post to the web of the beam. Then I am going to plate web with the piece of 3/4x7". Lastly I will plate the 3/4x5" over the sides of slide post. I think that should do.
That should do it.

Plugs are welded and the bottom flange to the plate. The bottom flange pulled about a 1/16" as I figured it would. Now I'm going to tack in second plate and tack in gussets to control top flange. It needs to stay put where if is. I will also clamp a heavy plate to top flange while welding out and it will stay in place till all is cooled.
My flange pulled also when i was welding in the plate. I stitched welded alternating side to side and then back stepped the welds to fill them in. I also welded my top flange plateing before doing the web. This kept things reasonably straight. When ever I would notice any warping, I just flipped the beam over and would weld on the other side to pull it back in place
