I see a new job coming up.
Lenny, I can make all you need, as the stuff from a DIY isnt what you can use.
Just email me the plans, and well talk about it trough Email or MSN
using normal threaded bar isnt a good idea, the thread is to fine and will lock up easily.
Thanks for the replies.
Grant: The size of thread Im using is 8mm. The maximum length of the tube would be around 250mm
Alan: I wondered if that might be the case, its just the threaded rod is all Ive got as Im still getting round to buying a car jack thread (moneys currently an issue), plus the normal threaded bar fits into my drill motor driveshafts (I had to tap them because I botched the modification process and ended up cutting off the threaded axle that was already on the drill)
Mario: Thanks for the offer - itll take me a couple of days to get round to doing some plans, Im tied up with some stuff just now. I dont have/cant work CAD but I could draw them as accurately as possible in Appleworks and save them as a JPEG if this would be ok for a set of plans.
Many thanks,
Lenny
Normaly it would work Lenny, just send it over and discus work.

You could go to a scrapyard and get an old car jack, look for a box/square type thread your probably get it for next to nothing or even for nothing especially if you tell them its for building a robot. It will also have the correct size threaded attachment to go up a down the thread. Thats what we ended up using in Rampage.

Thanks for that Ian, I might try that now that Im on holiday.
Mario: I sent you an email regarding the custom parts, hope you got it OK, if not let me know, and Ill send it again.
also lenny, if you use normal high tensile thread (which will be perfectly fine if well greased) then you will not need a complely threaded tube. just get someone to weld a tube on the end of a nut as that create less friction and easier to make!
Im planning on building a chassis out of some sort of box section metal and i was wondering if i should use steel hollow square or aluminium hollow square? and what kind of sizes?
Id suggest that you use steel......( and Im basing the sizes on your previous posts stating that your hoping to build a heavy ) ... either box or angle with a 3mm wall.
So box section 25mm x 25mm x 3mm ..... or 50mm x 50mm x 3mm equal angle.
NOT ALUMINIUM for your first attempt at welding!
no this is for a feather (i know im really confusing)
