you are beating a dead horse. the angle iron it not going to twist.

the cross bars actually do two jobs. first. keep it from deflecting length wise.

and the they keep the angle iron from twisting. the cross sections will be laying on every part of the iron.

and my tests from before told me the angle iron did'nt really twist by it self
... when adding constant pressure. because i got to go to my dads work over the weekend. ad i did some more tests. the iron does twist when adding fluctuating amounts of pressure.

consider angle iron like ceramic. hard to break with constant pressure. and easy to break with a hit.



and

i hate alot of people my age. in my physics class, we sent the last three on difference of a distance time graph and a displacement time graph.

jeez. i think they should all take biology instead. god

To be fair, your sentences are mostly incoherent, so I have no idea what you're talking about You sent the last three on huh? Wha?

Also - angle iron, ceramics... constant pressure vs fluctuations? This all seems very irrelevant, and you should never compare any metal to a ceramic. In a couple more years you'll take some kind of structures class, and this will all make a lot more sense (assuming you go into engineering, which lets be honest... all the cool people do )

Your cross bars aren't your weak point, so save a little money and just get normal steel bars instead of holding out for spring steel, my two cents.

wow
when i type fast it doesnt really work out right.
i meant to say.
in my physics class. we spent the last three days studying the differences of distance time graphs and displacement time graphs.

i was thinking either mechanical engineering or kineisiology

UPDATED!

The conveyor was a great find! Good deal on the planer too.

Yeah that conveyor thing is awesome! We just use these roller things from HF, which work ok, but it can be a pain if your crib is very heavy (ours weighs a ton)

the conveyor is good, but i dont think i really need it. i do plan on getting another one for the entry side.

its origional intent was to prevent sniping, but that didnt work that much.

and my planer crib is heavy at all. its made from twopecies of cabinet mdf ( i dont know the exact thickness, but i know its less than 1/2 inch)
and i kept it rom flexing by putting great suff in the gaps. cheap, cheap easy to make planer crib.

It expands, right? Just chop it in two and fabricate another set of legs.

well, possible. but it only expand to two metres. and one meter conveyor is kinda pointless.

plus, i think 50 dollars it cheaper than getting a steel cutter for that size.
AND having another conveyor is never bad. but i wanted to change thos skids a little bit. they make theese two axis rollers, i want to put like 20 on each skid. because those skids are as high as the conveyor, AND as high as the deck of my press. so easy layups.

Dude, HF angle grinder and a cutoff wheel, you can cut through anything.

still cheaper. chea[pest angle grinder is a ryobi and is 49.99 exactly

and i planed some cores today. nothing secial just to practice the entire routine, i bought some 4x 1/2 planed them down to 12mm thick, measured with my new mitutoyo calipers, god those are explensive. then glued them onto my crib. and vroom. two cores, half an hour, +- 0.5 mm difference to origional plans. which were 3-12-3 mm . it came out 3.2-12-3.3. i can ost some pics if intersted.

HF angle grinder is $12

http://www.homedepot.ca/webapp/wcs/stor ... PartNumber

its 59.99

and then, a super bad quality one

http://www.homedepot.ca/webapp/wcs/stor ... PartNumber

39.99

and plus one meter sections arent enough to make a difference.

id rather just buy one more

You have much to learn in the ways of Harbor Freight my friend

For things like this, HF all the way.

That one is typically on sale for $12. I have three of them, one I've had for about 7 years now, still works like a charm. Not even for your roller thing, its just another handy tool to have if you're doing any kind of metal work (cutting or grinding)
