Mod 1 will be fine. though i really don't recommend you attempt your own gearning on your first featherweight.
thankyou so much i have got the gears and motor sorted out. I am going to turn this topic into a thread because innevetably i will have more newcomer questions. I sincerely thankyou all for your help on my major motor prediciment.
i need a 5mm hole
Depends how accurate and in what material on what location.
If it is on your gears/ pulleys then technobots will drill out the centres for you as long as the bore size isn't larger than the size you want to start off with
You really haven't listened to the good advice on this thread as far as I can tell (although there is a fair bit of crap in there too).
For a first bot, DO NOT TRY AND MAKE A GEARBOX YOURSELF. You will will have a hard enough time trying to get the other systems working and put together into a chassis. Buy a couple of drills or the gimpsons and use those as a nice drop in solution. Run them at their rated voltage and use an appropriate speed controller. I'm always a fan of the electronize as they are nice and simple, very rugged.
Once you have built your first machine and attended an event and spoken to people, you will have a far better idea about voltages, gearboxes etc etc. Trying to machine a mod 1 gearbox without a mill is a pain in the arse at the best of times. Not impossible, just a pain.
I only can agree with Gary.
I made assembled quite a few gearboxes myself. Batterydrill based, speed 600-700 and 900 based, and for heavyweights Iskra and Bosch based ones.
On the other hand, I have acces to a reasonably complete metal working workshop at home, and the support of very fine engineers with even a more impressive array of tools.
Even then, I opted for Gimsons in the newest Hannibalito to speed up construction and ease of replacement
The 4th of the line. 1 and 2 (Wedgie) are sold.
And is in continous use sinds it's first outing, proving very reliable and with a fair turnaround time. (from arena removal to -barring battle damage CO2 filled and recharged in 15 minutes)
i am going to use the gimsons ( even thought they are too expensive for my liking) i will use 12v as that is what they are. i am using a sabertooth ,even though you are all saying not to, as they are cheapest i can find and i dont have to pay postage, i will collect them. My robot will look stupid from the side with a wide diameter chasis but really small motors but i guess if i used anything else i would muck it up.
the gimsons motors com in either 9.6v or 14.4v last time i looked and which sabertooth as the 12a ones are ok if you don't intend to do lot of pushing cos i had my robot pushing against me and it kept cutting out for a split second ...... so the 25a ones would be better i think
okay
