They're nearly double the price. Would be better off with Gimsons if you're going to spend that money.

hamer drills wont work.
Get the simple Â£12 drills.
It isnt always about horse power, grip makes a massive difference

ok
just thaught it would work
and I'm not doing it on purpose, it is a cordless drill like you said.

i know it sounds like i wont take anyones advice but i keep mithering about the things ive found/want because nobody has realy given me a reason as to why hammer drills wont work.
if they work as perfect cordless drills why wont they work in a robot.
i am perfectly happy with using argos drills but i made this thread to try to answer my questions and i havent started the build yet. so i just want answers to my questions.
have cordless hammer drills been used before.
if not and there is no obvious reason why they wont then there isnt much harm in experimenting with some cheap ones.
if there is a reason can someone just tell me and i will give up on the idea
thanks

Because you have to permanently disable the hammer mechanism. They are setup differently inside and are a pain in the arse. Believe me, I've played about with some. They work as drills because they are nicely housed in a plastic casing, something that you will be removing along with most of the mechanism that keeps them from hammering away. Stick to regular drills.

ok thanks Gary.
i am sticking to cordless drills deffinatley.
i broke a gearbox an a dewalt, my dad was ok though, it.didn't work.
i am really really really sorry for not.listening and i wish i could start off fresh (so people aren't angry because robots is one of my favourite things in the whole world.)
i suppose i.should start simple then get experience and make some more friends

i.will start my build in about 1 month and will Check through some older topics for info and tips
just now, should i buy that speedo from gripper and corkscrew?
seems worth it.
thanks guys and Gary for answering my question.

That speedo that Jonno is selling that came from Corkscrew is a Heavyweight speed controller. Its FAR too heavy for a FW and majorly overkill unless you are running something daft. Only FW I know that ran a HW speed controller was Trojan, and he was running these 2 massive 200W scooter motors, and even so, it was overkill.

If all your running is drill motors, a Scorpion XXL will suit the needs fine. It takes up to 24v so you'd be fine with it.
