Earthwormjim's Stuff

That's fantastic how do you make the ti scoop bends with 1mm so neat? Mine are all a bit, well, imprecise :p

[earthwormjim]

Thanks Dave.
Bends were made using a very big vice,with aluminium jaws,a really big hammer,and a grinding wheel!
And a fair amount of elbow grease!

What do you cut the Ti with ? I have to cut the 1mm stuff with either my angle grinder or a dremel!

[earthwormjim]

I use a jigsaw!
For Ti,I use a fine metal blade,which goes dull after about 20cm,but is still useable for alot longer,albeit with alot more force behind it.For the bits that I couldnt get bthe jigsaw into,I used a dremmel,but went through 3 cutting disks in about 4cm!
Then I use a bench mounted grinding disk(£20 from Lidl),to fine tune the edges.
I wouldn't like to work with anything thicker than 1mm,it is seriously tough!

Your metal bending and cutting skills are really quite impressive that looks great.
Those wrap arounds on the edges of the scoop make it very difficult for a spinner to catch any edges.

And with that comment Peter is thinking "dammit Jim I'm a destruction engineer not an 'I'll have to out drive that thing to win' engineer !"

He'll be looking for ways around it now

Jim that looks excellent! Can't wait to see it in the flesh even though it looks like it will give the Inertia's a bit of trouble

Ha,thanks chaps.very kind!
The 540rpm motors seem to be struggling to move the full 150g around.It was alot faster and more responsive without the armour.
I may try it with some hp motors and see what difference that makes.

I really should wrap this one up,and get to work on poor old Raoul.
Cheers Jim.
