Ferm and Clarke are different brand names for the same kit - cheap to buy - and unfortunately it shows. My Clarke hydraulic bender is good though!

Other essentials - Decent cable stripper (prevents losing those extra strands when you use a penknike) Decent cable crimper - will safe a lot of headaches in the future.

Another robot essential - 2 bottles of thread locker (Loctite). One should be Nutloc - for fasteners you want to be able to get apart but dont want to shake loose. The other should be Studloc - serious stuff and the chemical equivalent to welding - forget ever removing a fastener coated with this! If you want to be sure either threadlocker adheres properly - get a big can of brake cleaner and wash the nuts and bolts in it first.

If you want to use pop-rivets, dont buy the B&Q cheapo - they are rubbish. Get a good one instead. I like the Lazy Tong type - in fact I want to build one into a robot!
