Fatgirl build

[05CTD]

My experience has been the opposite on thick plate for CNC'd holes. Plasma leaves a very unacceptable taper, a 4 degree taper is acceptable per Hypertherms guidelines. Every hole we cut with our plasma table gets reamed. It sucks, but it still takes way less time than laying them out and drilling them. If I wanted something accurate and precise I would waterjet cut it. I don't have any experience with Laser cutting.

Honestly, when you're talking about reaming holes drilled that were with an annular cutter, and then having the table blanchard ground, I think you're going waaaay overboard on this table. Are you building spaceframes for Space-X on this fixture table? You're going to be thousands into this thing. Put the energy and money into the build. My $0.02.

I can see what you are saying about overboard building. I’m already into it a little over 500 with metal and frame I just ordered casters that makes it about 600. I got quotes back from laser cutter and not going that way. I will likely only do surface grind. Part of this is I do fabrication on the side. I am just going to check the run out on an annular cutter and see likely I will just bore all the holes with it. I can draw in CAD and print off to scale at work center punch the holes and call it good. Thanks for saying I’m going into this to far I tend to do that quite often.

I just checked the run out on annular cutter is +.004 -.000 that will work. So I ordered a annular cutter and will lay out and print to scale the grid pattern today at work. Thanks for the info.

Just make sure all youre fixture tools are same diameter as these holes!!!!! Lots of drilling for nothing if they dont work together. Probably not need said, but sometimes cart goes before the horse and we get ahead of ourselves.

Your plan to plot the grid and centerpunch is exactly what i would do for a home brew. Id probably punch them all and drill 50% immediately, then see if you really need as tight of a pattern as you think.

Post photos as you go for us!

A standard fixture table uses 5/8 holes for the fixtures. I've already made some 1 inch locating pins turned down to 5/8 for the holes. Will do on the photos. I also ordered some drawer slides so I can make a shelf that moves in and out for the Tig welder. My casters should be here today and the annular cutters delivery date is Monday. I printed the grid off at work yesterday to scale. Dang that's a lot of hoes if my math is right 512 is the total. I hope it turns out as good as I think it will. I also ordered some F clamps to make hold down clamps for the table. Thanks again for the advice...

Casters are here. Caster plates made. New Mag drill got here yesterday along with my new cold saw. Annular cutters set plus 5/8 spare still not here grrr. I won’t finish fab table for a few weeks headed to the coast to camp on the beach for 10 days. Beer crab and oysters are in my future.

Went on vacation to the coast for 10 days was supposed to be two weeks. Had a molar crack in half and apparently I swallowed it but it split from bottom to top. Just for others info the VA does not authorize any emergent dental services. So I came home went to VA and the referred me for oral surgery so got that done last Friday ended up with 17 stitches in my mouth.

Anyway back to fab table I have 77 of the 512 total 5/8in holes drilled into top and carbide annular cutter is still sharp as can be.

You are 15% done! Haha, that is a lot of damn holes.

Holy cow man, that does not sound like a fun way to end your vacation.

Sorry i could not make it down to hang out, between the kids and inlaws it was a hectic week. I will let you know when i head your way next.

Over 400 holes in now it is finally looking like a fab table. Still on my second annular cutter first one broke a tooth off at about 125 holes.

Building a 2hp 2x72 belt grinder for shop VFD and motor supposed to show today. I bought the plans off some dude on Youtube they were originally supposed to be built out of steel. We had two damaged sheets of 1/2 6061 at work I bought for scrap and re-dimensioned it out of 1/2 aluminum instead of 1/4 steel. I built it so I can cope the tubing in my cage tight. I can run the standard grinding platen or remove it and install a wheel same diameter as my cage tubing to be able to grind tubing for tig welding cage.

Question for the guys running LS w/auto trans. What stall torque convertor? When I originally put my drive train together I went with a TH400 800RPM torque convertor. My original thinking was right off idle power without torque convertor slipping. I dont know now tho??? I am running 4.56 gears and 40's. I have 4 wheel disc brakes. What stall torque convertor would you run?

OH btw my 6.0 has been on engine dyno and puts out 491hp to the flywheel. Should be about 425hp to axle.

Im so damn tired of drilling holes especially in this heat. I go out and drill 10-15 late evening and call it good for the day haha

Drilling holes in anything thick suckkkssssss. I feel your pain on that.

 

[05CTD]

Looking for info if someone has it I am at work and I’m building trans/tcase crossmember. I have TH350 K case with advanced adapters 1.5 think mount. I am looking for the bolt mount pattern for the foot of the mount. It uses 2 7/16 bolts. I need to know center to center measurement so I can milk holes.

If anyone has it by chance I’d appreciate it?

Thanks

 

[05CTD]

Grrr drill the holes on the mill not “milk” dang auto correct

 

[ceylonfj40nut]

Man some pics would make this more interesting.

 

[05CTD]

Sorry I do the same thing all the time I finish something and then think damn I should have took pics. Here is my rear atlas support I tig’d up this weekend

 

[05CTD]

Here’s the pic of atlas support it is short since I’m running a flat belly

It’s been busy momma has had me on house/driveway duty for a bit. I did build a stand for 2x72 belt grinder I made it kind of modular so it can hold one of my bench grinders and my dimple die press either one. I also picked up a 2hp Bridgeport knee mill with CNC servo drives on X and Y axis. Here’s a couple pics of grinder stand I’ll have to take one of Bridgeport later

Variable speed, thats a sweet sander, nicely done, makes such a diff in production, quality, and just motivates you to work on stuff.

Yeah and typical me I couldnt run the 1 hp motor so I put a 3hp 3450 rpm motor and then went from a 3 1/2 drive wheel to a 7 inch drive wheel. It will definitely remove some metal now haha...

 

[peesalot]

You'll like the 3hp , it will keep speed which makes for more even job.
