Love the frame.

Do you have any drawings and dimmension of your frame? I have been looking to do the same method as far as a overhead design. I am curious as to your progress.

I have large size people wanting armor so I am going to attempt to make a slightly larger size Vaccum form machine which is one reason I am looking at the overhead design.

Any information on you frame would be helpful.

It is basically a 24 x 24 table top and everything goes around that.

I used the 1515 as a starting point when making the design. Go to www.8020.net and you can start from there. 1515 is much stronger than the 1010 and I do not recommend 1010 for strength applications. My set up will weigh over 300 pounds when completed.

The material is not cheap. You can probably get some of it cheaper in the EBAY garage sale but chances are the ends will not be anodized.

When I get my new computer up and running I will see what I can do about getting you specific dimensions.

Update: Still waiting for the local fabricators to make the oven box and frame holder. They are continually backlogged with work and my stuff is being pushed back. Was told on Monday that they would start it in two weeks. Crossing fingers as I was told that same line every two weeks that I call them.

Question on oven, will an oven element in the 24x24x12 stainless steel box be sufficient to heat ABS? If not, I need to start obtaining niachrome parts.

New computer is coming along, but will still take time to set up. You can view what I am putting together here: http://www.dfi-street.com/forum/showthread.php?t=60643

Go easy on me, been five years since I put together a computer from scratch. I am a little rusty.

It depends on the size and shape of the oven heating element. Remember, you want to concentrate most of your heat around the perimeter of the oven, then less heat in the middle. I think nichrome wire is the only way to achieve this requirement since it allows flexibility in the layout.

But there is that crazy guy in Great Britain that used portable heater elements...

Good luck!

Alright Charlie, where do I get all the parts for the wiring and stand offs?

I wonder if it will be possible to wire this into 220 and still retain the oven controls.

Where is your link on oven wiring?

Thanks.

Resource for niachrome wiring and stand offs?

I am going with 220 volts single run for best results.

What link has the best write up on construction?

you can get the nichrome wire and the cermanic stand offs at:

Hi Mattax,

The link for the oven calculator is:
http://www.tk560.com/phpBB2/viewtopic.php?t=272

Just plug in the details of your table, and off you go! It will also calculate for 220 volts.

Now if you're looking for details on how to construct the oven, just go to Jim's Vactable 4 page, almost halfway down:
http://www.tk560.com/phpBB2/viewtopic.php?t=272

At the bottom of the page you will find links for the nichrome wire and ceramic heating posts from InfraRed Heaters.com. If you want to go with the ceramic donuts (instead of the "hats" on Jim's table) just be sure to ask the salesman about them when you call. He'll be able to pick the right part for you.

My ridiculous huge write up is in this thread:
http://www.tk560.com/phpBB2/viewtopic.php?p=193&highlight=#193
(mann, that's a pretty layout of the nichrome coils )

If you are planning on using regular home oven temperature controls for your rig, they should work fine, since those also run at 220v The main thing to check is the power rating.
Volts (220 in your case) x Amps (to be determined by the amount of nichrome wire you use) = Watts

Compare your calculated number with the ratings on the oven controls. The oven control should be rated for more watts than your oven will use.

Good luck!

Mattax,
Any new progress on your Machine?

I'm very interested in seeing how it turns out!!

Sorry have been really busy with setting up my new computer. I will need this for AUTOCAD.

I was trying to get the frame pull down system and all support parts ordered from 8020 before the top of the year with a 2 and 1/2 month lead time for them to help design the exact parts and they dropped the ball - royaly! So, now am playing catch up.

I should resume work next month. In the meantime I still need to order the oven wiring and standoffs. I still have not heard a comprehensive manner both electrically and physically in which to wire the 24 by 24 oven for 220 volts. Any takers?

I have been looking over the oven calculator and am having issues trying to figure out the best layout for the 24 x 24. Should I go with the default 6.5 inches of layers?

Also, I plugged in 220volts, 3 segments and it shows

Cool fabrication material you are using! Seems a but expensive, but neat! I can see all sorts of other applications for this sutff!

I was actually thinking about the aluminum frame material.
