The Taco Press Project
 
3 Attachment(s)
So I started Cutting the material for Dubby's Taco press...
Got the material cut then I beveled the edges and laying it out to see which way will be best for the hinges.

Still, need to remove all the scale and round the corners enough to not be sharp... Then Sandblast all the pieces.

I am thinking with approved by dubby adding some flip tabs to the two sides and top... Then cutting the bottom of the C-clamps off and they will pin into the tabs and then just swing over the plate from back to front or vice-versa... and then they can be adjusted to compress the material between...

What is the best way to remove the scale...? My blast cabinet is not working been tooooo much humidity lately and my media is all stuck in clumps.

And I am having to work at night when it's a little cooler and mosquitos are not out for blood as bad... So I don't want to run the grinders if possible...

Chemical peel;) so what are some options... ??

Best option I know other than blasting is acid strip. Which is not my favorite because of the extra safety BS. I bought a jug of muriatic acid to strip some Corten roofing for a heatshield behind my woodstove. First batch wasn't getting it done to my satisfaction. The next batch was melting brushes:eek::eek: Buy more media for your blaster.

Yeah, I figured I'd be buying more blast media for that, that blasted blaster anyway. well, once I saw how clumped up it was...
I'll try to save the old stuff It was new and used it for like a five-minute blast job... But I'll see if I can break it up and run it through the wet blaster, but it has to be as dry as if it were going to be used in the blast cabinet.

And I'm too lazy to screen it and that's a messy job plus its only 10 bucks a bag so prolly just as cheap to toss it and get new dry...

It will take 2-3 days. Hand wire brush off and rinse.

Well, I had a bad od 40 grit blast media a bit rough but took off most of the scale and while I was messing with tips for the blast cabinet to get it to half-ass work with such a heavy grit. the benefit of the course media is it will take a nice coat of primer so should help adhere nicely and make for a nice coat of paint too...

I came across a spray I had forgotten about that removes the galvanizing coating and I've used it to remove scale on the plate before so I sprayed the plate pieces down and will wipe it clean in the morning well whenever it is I get up stress yet again has me some odd hours again...

Been in the shop since 1.A.M. so got a little more time in on it.
Will figure out the hinge placement tomorrow and get that welded up.

I'm second guessing the flip over C-clams as I prolly bought the wrong size C-clamps not knowing how wide the opening will be still with the material in it ready to compress. and thinking I will need to figure out another way to do the clamping...

Ya can tell by the blast pattern besides the heavy corse blast media I was having a moisture issue as well... Bet my tank has water in it, being I hadn't drained it in a few days... Yep sham on me :p;)

Getting close to the taco, taco press... so the spray did not work to remove the rest of the scale must be too old as it didn't smell as pungent as when I first picked it up so washed it all down dried it off and figured the placement for the hinges.

And now I'll make the clamping wedge for the bottom so it can be held in a vise... that is after I get my shielding gas changed out, ran out in the middle of a weld which always sucks... and so now I am out of the 75/25 mix and will have to switch to the CO2 which I don't care much for...

So When I'm done with the welding... I decided two c-clamps will work there just won't be room for the three I had planned on...

Then I will wet blast it to finish cleaning it up... being I had forgotten I even had the wet blast attachment.

So it is getting closer to being done little by little having to weld and grind left handed cause my right arm will not support any weight no even a can of soda pop/cola so if ya are wondering why such a small project is taking me so long I am becoming more and more limited so this might be my last project for some time.

Here are some more pics Dubby let me know if it is looking something like what ya wanted...
