Your machine is coming along great.

Excellent photo's.

The welds look awesome. They look like they were done by a professional.


Thanks for the compliments!!!! I need to pick up a couple more pieces of steel to finish off the carrier frame...hope to get to it this weekend.

very nice design!

Looks great, keep up the good work!

how much power is your oven pulling in amps?


I'm not sure how many amps this thing will pull but I'll put a multimeter on it once its complete. This would be a great question to defer to Doug...you out there buddy?

Coolness. Too bad my priorities changed, I'm back saving up for a laptop now. Laughing

Maybe when I get established and out on my own I can save up for this again. Confused

Even better; just go to YouTube, and you could find PLENTY of tutorials of MIG Welding, or just GOOGLE it under MIG WELDING TUTORIALS....and man, you'll see HEAVEN when it comes to tutorials....believe me.

Haven't tried any of them yet, but looks really neat.


Wow, so you really think I can learn just from online tutorials? Neat...

Now the only problem is the cost of the tools. XD

Darst....... Evil or Very Mad



Is this a decent welder:

EDIT: Looks kinda dangerous:

Heat, UVs, WOW!!!!! Shocked

(I knew about the heat, I had no idea MIGs generated UVs tho)

The exact amperage depends a bit on your supply voltage but the modular oven elements are around 1200 watts and 5.2 amps per square foot. I think that's much more than the Thurston james type ovens?

Thats a great looking machine. Being able to weld and access to a welder seems to make a difference.

Unfortunately I do not have access to a welder and it seems like it would be very expensive (Welder, gas, Protective gear, Welding table).

So I am trying to figure out an alternative to welding but still use metal.

Harbor Freight frequently has a small flux cored wire welder (no gas needed) on sale for around $100. It is not the kind of machine you could make a living with, but it will stick two pieces of steel together efficiently.

Buy one, get a couple of good books from the library, watch a few hours of tutorials on the web then get some scrap metal and practice for a few days. You won't be ready to start welding gas pipes, but you should be able to make solid joints.

For around $150 you can get the welder, some gloves, a chipping hammer, a cheap grinder and cheap mask. I would recommend spending another $40 or so for an auto-darkening helmet, as it will make it easier to line up your work and shorten your learning curve.

You will have a valuable skill and a new tool. What could be better?

Thanks Bryan, should have known harbor freight might have something...going there is like visiting heaven, mecca, Valhalla or your preferred choice of paradise after-life.

At some point I'm going to convert the plans to digital format and offer them on CD at a lower price. I'm not sure how much I'll revise them but I will most likely add more pictures. Maybe if you're interested, you could put all your pics on a disc and sell it to me so I have more images to choose from?

Keep up the good work..

Doug

Doug,
I am interested in the digital version. can you PM me or send me the details.?

Properly wired, a 115V TJ oven will have 4 parallel circuits, each will draw 5.2A at 115V and each will have a power rating of 600W. For a total of 2400W, drawing 20.8 A.

Harbor Freight will have the 90 Amp wire welder on sale for $87.99 in a couple of weeks, March 13-15 only. Flux core is much easier to learn than stick welding.

The carrier frame is completely welded together and painted. I even welded in some L brackets to hold some tiny clamps.





These clamps are TINY!!!!



But they fit real nice on the frame and each one has about 50 lbs of clamping force.



I still need to drill the holes on the brackets and mount the clamps to the frame.

I also was able to get all three platen frames finished up.



And started forming the aluminum sheets to the frame. I got the 2x2 sheet formed and started drilling all the holes....



About three quarters of the way through, my drill took a dump! I guess I burned out the motor on it. Oh well, it gave me an excuse to go out and buy another drill. I ended up buying a Milwaukee 18v with the Lithium ion batteries.



This drill is really nice and its making quick work of the holes. It is VERY tedious drilling all those tiny little holes. I am NOT looking forward to having to repeat this part of the process on the 2x3 AND 2x4 tops.

Todd

Your table is looking good dude. Where did you end up getting your clamps and what size are they?

Those platen frames look soooooo beautiful! (not to mention the whole machine as of now, which is WOW). Keep the good work, bro.
