So, as I posted in my original build thread, I sold my fab table. I have been driving myself nuts the last couple days, since my table is pretty much the hub of my working area. The table was a complete beast. I loved it, but, like many, with the burden of trying to make due with limited amount of space, something had to change. My affinity for machine tools keeps growing, which means I had to make decisions.

I had ideas about how I would build another table if I got the chance. I have the ability to do all of the machining now, minus the grinding, in house. The last table was built around the 5/8" top and building pretty much the burliest frame I could using materials of opportunity.

I really liked using my old table, however, with my original small lathe, making some of the tooling was a chore. With my new Cadillac lathe, things go quite a bit faster. Tooling designs are going to be different and I plan on making a good amount of stuff right off the bat. I mainly used clamps I modified. Those all went with the old table.

The grid size will be smaller, with a 2x2 pattern, keeping the same 5/8" holes. I'm leaning toward changing the design on the end blocks, but that's the idea I had in my head when I drew it. The plates will be 1.25" thick, or possible 1.00 depending on pricing I can get. I told the wife I'd keep it under the $1400 I got from my old table. I will most likely send the plates out to be match ground, basically get them cleaned up. I will machine to length.

The main runners are hitch stock, so my accessory stuff, vise, etc, will still fit in on either end. Still need to design up the frame. I plan on bolting together everything to do with the plates and the main runners and then bolting that assembly to a welded frame.

I should be able to order materials this week and pick them up this Friday.

Here is what I have been working on, using Autodesk Fusion 360 (which is free btw, for CAD and CAM):

Looks like it's going to be another nice table.

Can you tell us more about the small blocks on the front and back of the table?

They look fancier than they are, haha. Just stop blocks that drop below the work surface when you don't want to use them.

subscribed. Trying to figure out what all the holes are for, but I'll just be patient for now.

I'm guessing drilled and tapped & blanchard ground slats?

The holes are for whatever you want to use them for. They will just be drilled to 5/8, which is what a lot of tooling already is for this type of table. You can use them for stops, bolt holes, drop in clamps, etc. I'll build some stuff to have around but can also build something specific if I need it.

Yea, I have another idea for the sides I might try out to get an edge like the Siegmund/Bluco tables.

Sooo, for anyone that's interested, did some pricing on steel yesterday. I've also changed the design slightly. Going to be using 12"x36"x1" thick most likely due to availability (still waiting for a quote). The main frame will be 3x3x0.188 square tube.

I was originally looking at 1"x12" flat bar, that comes in 12' sections. I figured it would be mostly to size, I could have them rough cut to length, leave me some meat and I could finish machine and have them ground. I had actually paid for the materials, which was about $1100 for the two 12' bars. Then, out of curiosity, I had her price a full 4x8 sheet of 1" plate and I was able to get that for $650ish....sold. So that's where I'm at now. I'm waiting for a quote on 1.25" plate, but that apparently comes in only 8x20' sheets, so she had to send out a request, since they would basically just cut out what I need, where if I get the 1", I'll buy a whole 4x8 sheet. Damn, metal buying is complicated, haha.

I'm drawing up a quick .dxf file to get quotes on cutting, since they can waterjet at another location. Getting prices on having just the perimeter done and one with all the holes as well, so I don't have to machine/drill them myself. Hopefully it's reasonable so I can pick up, machine a few features and them have them finish ground. I'll have them waterjet slightly oversize for finish grinding. Plus, I'm buying the whole plate, so I'll have another 17 sq ft of 1" plate left over for other stuff.

Option 7?: Cut the strips with your PM 85? Then machine the taper off?

Last time I got a cut price from my steel supplier (while providing them with a .dxf) it was insane. Like $900 for something I would price out at $150. This was just cutting, no material cost.

1" plate makes nice press plates!

Yea, I've thought about cutting on the plasma, but I'm not sure what kind of tolerances I can get and I'm not sure I want to experiment. Maybe after the fact on some scrap. I want to try cutting out press plates.

I'm going to check the steel supplier, just because they have the ability, but I have a few local places I can have quote me. The water guy I had do my last top was reasonable, but that was also 5/8, not sure how much extra 1" will be. If it's that expensive, I will just machine them all on the Bridgeport. I got more time than money if it's too spendy.

I did a 1" foot for the log splitter rebuild I did recently on my 65. I could measure the taper on Monday, if you'd like. I ran it pretty fast, it could have been a lot better, but it could give you a worst case scenario.

One other thought I had. Double check with your sales lady that the 12" strips weren't a higher grade of steel or had a call out for flatness. I cant think of why the price is so different if they are the same as the 4x8.

The CRS bar is definitely going to be flatter and also on size for the 12" width over HRS sheet. I know it's always more money. I'll be sending the plates out for grinding though and if I need to add more structure in to hold them flat, I will.

Oh, I didn't realize you were speccing cold rolled. Our supplier only goes to 12 ga on cold rolled. I usually use P&O above that thickness, but it can be hard to get above 3/8".

Yea, it really is crazy how many options there are when it comes to solid slabs. Tubing is a little more straight forward. I figured for less than half of the price, I'll deal with the HRS, since they'll be ground anyway. I've got a 50T press I can use to get them close to straight, but my metal place has always taken care of me, so I'm hoping they can just get me a good plate to start with.

I'd def be interested in seeing what you got for taper. It would be a good chance to push the 85. You didn't have any problems piercing on the 1"?

I edge started the 1" on my PM 65. I would hope your 85 wouldnt have a problem piercing 1". I am going to upgrade soon to an 85, but I am in the middle of a 40x60 shop project.

did you find a larger grid size harder to work with? i saw you said you were going to go down to 2x2. i'm hoping to build a fixturing table in august and was going to price the difference between 4x4 and 2x2 and figure out if it was worth it

There were a few times I wish I had holes on my old table closer together, but it's not a deal breaker. It still worked fine. I think any grid is better than nothing, even a 6x6 is enough with good planning of where you align your projects and intended measurements. I'm going to change my clamp design a bit, so they should have more reach anyway.

I really just chose the 2x2 because I'd rather have more options than not. The holes also allow for flexibility with mounting the plates.

I measured the taper on that 1". With my crude Chinese measuring tools it looks like .072" of taper. Like I said, I could have done a lot better, but it's a foot on a log splitter...
and I only have a 65 amp machine.

Good to know. I got one waterjet quote back at $280 a plate, so for that, I will do it myself. I have a few other quotes to get. I also have read a few things on the wiggle pierce, which I was thinking of trying. Have you tried that at all? I might just have the 4x8 sheet cut into 1x4 sections, then I can experiment on a few with the plasma and if everything works, just go for it. I figure I can draw some files for press plates and even if I screw them up a little with the plasma testing, I can machine them down and not totally scrap them.

Edit: another waterjet place came back at $625 each, haha yeeeeea.

Yeah I have tried the wiggle pierce. I dont know that it helped all that much, but it certainly sprayed sparks inside the garage in a lot of different directions really quickly!

I think your 85 shouldnt have a single problem with piercing 1". Use an older shield and nozzle to pierce and then change out consumables to fresh ones before you cut the rest of the lines. Or, drill holes manually where your pierces are. Or, edge start (you need strips anyway).

I like the look of this bench :drool:. Very impressive. Way better design than my current one. mmmm Maybe i need to make a new bench when I have mine completed. I'll be following with great interest.

Thanks. I'm excited. My frame/rail material came in, I just need to go pick it up. Still working out some details on the top. I'm going to be out of the country on vacation for a week and half, but I should be getting started when I get back.

Could you use four 2 or 3" tubing offset on each side so you could slide out to help support longer work pieces.

Aye, been busy with other stuff. I picked up material, minus the top plate. I need to start cutting down and machining, but I've been playing with my plasma on my few days off. Hoping to get started this weekend, but I still have a Kurt vise I need to put back together that I bought a rebuild kit for. My biggest challenge always seems to be just finding free time.

This project is probably going to get shelved, at least for now. Bought a small 2x3 table from tabandslot.com that I need to put together still, just been more busy running plasma jobs and other stuff, plus, not enough real estate in the garage for what I want currently. Some stuff in the works and if it does happen, I'll update the thread.

Should be fine. Most of the stuff is personal preference. If anything, it's a good machining exercise and you can always build another one.
