  Dear All,
  
  can u all pls help me.
  
  This is a follow up of this thread - A screw or bolt remover.
  http://www.sgforums.com/?action=thread_display&thread_id=256752
  
  Btw I am in Industrial Design.
  
  The problem i am trying to tackle, to design a feasible and portable tool to remove rounded screws and misaligned bolts.
  When trying to remove spoilt parts of a vehicle during out field training?
  For example, a spoilt gearbox.
  
  The target audience is Vehicle mechanics in the army.
  
  So my question to you guys is that.
  
  1. Do you guys go out with the vehicle during out field training?
  
  2. Are spoilt bolts and screws a comon problem?
  
  3. For example, if the gearbox spoil during out field training, and the screws or bolt is spoilt? wad do they do?
  
  4. Do they bring the vehicle back?
  
  5. Wad other problems will occur when the spoilt screw or bolt is not removed?
  
  6. Do you guys think is this tool really needed?
  
  Thanks so much.
  If my questions are not clear, pls ask me to clarify.

  Gearbox cannot spoil, if spoil means tow back send to DSMB liao.
  
  Anyway we use power drills for rounded bolts and screws. If rounded we may try to hammer it off if possible.
  
  Your tool looks like what de?

  1. Do you guys go out with the vehicle during out field training?
  
  Yes of course
  
  2. Are spoilt bolts and screws a comon problem?
  
  Yes, mainly due to wear and tear, wrong size of nuts, bolts and screws used, incompetence of mechanics, nuts, bolts and screws not tightened properly before vehicle is used etc
  
  3. For example, if the gearbox spoil during out field training, and the screws or bolt is spoilt? wad do they do?
  
  Its a DX level job, must ask ST Engineering peeps
  
  4. Do they bring the vehicle back?
  
  Huh?
  
  5. Wad other problems will occur when the spoilt screw or bolt is not removed?
  
  Repair job cannot be performed on the parts
  You get screwed for not doing good preventive maintenance
  Parts can get loose during operations, eg, wheels come out when vehicle is on road
  
  6. Do you guys think is this tool really needed?
  
  Yes, but i cant comment on the current design

  Now called AMB ler
  
  Yah used power drills
  
  The tool...we ask him to bring during outing?

  For such a tool to be useful, it needs to be able to fit the different bolt sizes as mechanics don't just work with 1 type of vehicle and each vehicle have bolts that ranges in sizes.
  
  A tool that is restricted to only a certain bolt size or will require a tool for each bolt size will not be economical as rounded bolts etc do happen every so often but are not worth getting tools for them unless they are able to fit all the different bolts used.
  
  Furthermore, the size of the tool would matter as there are many areas where space constrain is a problem when doing vehicle repairs. Things like gearbox etc might be easier to access but as mentioned, most of the time such vehicles are sent to ST Kinetics (not engineering) for repair and not done by the AMBs.
  
  Current way to remove most rounded bolts as mention is by drilling but that destorys the thread and rethreading will need to be done which is abit troublesome so if you can really make something that can remove the rounded bolts effectively without spoiling the thread, it might come in handy to the technicians.

  I was a wheel vehicle mech. As far as tools are concern, the difference between armour and wheel and i guess track vehicles should be rather similar. The only slight difference i think is that for wheeled vehicles most of our spanner sizes are in numbers ranging from 6-30 while for armour they sizes are in fraction form if i didn't remember wrongly from what i heard from armour people. The exact fractions they use i am unsure though but i know 1/2 is roughly equivilent to a size 13 but differs by a very little.

  yeah, sz1/2 ~= sz13. but vm like to take sz13, 17 and 19 down for recovery.
  
  in fact most of our imperial measurement tools all chuck one side de, and we would rather borrow 13 from each other's tool box (cos it's the one that goes missing most often!) rather than take a sz1/2 from our own.

  Theres 1, 3, 6 and 9. Each of them is getting to be more focus on certain types of equipment as there been quite a few transfers between the AMBs this year. However i think it won't be appropriate to say what are these transfer etc in this public forum.

  Hmmm.
  Thanks for your inputs.
  
  Another thing which i wanna knw is that.
  
  1. How do u all remove the spoilt screws or bolts during outfield??
  
  2. If this tool can solve all the problems, does it affect the mecanics alot??

  I lack experience in outfield repairs but i would say generally most outfield repairs are simpler stuff, things that can be easily removed or installed within 2 hrs. ANy major jobs or jobs with complications will normally be towed back to base for proper repairs as there are limitations to what is done outfield.
  
  I am not sure about other bases but for mine i don't really face rounded bolts too often, maybe 1 every few months, rounded screws abit more common as i remember sawing worn screws every so often but generally i would say the effects won't be large but it would be a time saver when we encounter them.

  I would agree that most of the small and large 1s are useless. 13 17 19 are quite common and whenever i do 5 Ton inspection i would just bring those 3 as the most common problems is normally alternator or compressor belt loose which those 3 spanners can settle. 13 does get lost often and sometimes we use 14 when desperate which leads to rounding of bolts... A rule of thumb was to never ever leave your toolbox open especially if you are not around even for a second if not be prepared to empty your pockets when u are going to ORD and need return your toolbox.
  
  Recovery i'm not so sure even though i was recovery trained but i never went for any recovery ops before.

  The best is...if you can design a kinda screwdriver...that can drill a small hole on two sides of the bolt...so that the rounded screw can have something to catch on...
  
  You from PID? TP? Is Khee Huat and Helen still there?
