I am 170lbs 5'2quot; at the moment and I am getting married next september (2012) i just had a baby and i want to shake these extra pounds (and then some) before my wedding so that i can look great and feel greatmy dream goal is to loose a grand total of 50lbs40lbs is still great! however are the following commitments enough to loose the weight:eat high fibre foodslean meats, low fat foodsno caffeineno popno juice(just water)try to limit processed foodsno breadabsolutely no junk food and minor at home exercises every other day such as:walking (with a stroller) for 30min (or some days longer i walk 4km sometimes)push ups, planks, sit ups I am open to new suggestions but keep it simple, quot;funquot;, and easyi have never dieted before, i have weak joints (so heavy exercises is a NO), and i am breastfeeding so i cannot starve myself (even though i KNOW starving doesn't let you loose weight)
Dull the flutes on the drill bit a little bit and slow your RPM and the feed rate.
less pressure when you are almost throughOr dril all the holes almost though then turn the piece over and finish drilling from the backyou can use a deburring tool to remove the chip or an Easy out bolt remover, or a round wood rasp, rat tail file etc.
Use a lubricant like kerosene - keep the drill speed down - more drilling less pushing of the drill bit clear the bit often, rather than forcing the drill bit though the materialCheers!!
The material you are drilling through is only 3/8 thickYou are probably just using a regular hand-held drill with either a 3/8 or 1/2 chuck capacityThat's what most people have in their garageYour drill motor probably turns at 2500 RPM or less so any thing to do with High Speed drilling can be set asideYou also do not need carbideWhat you do need is a very sharp cutting edge on your 1/2 diameter drill bit You have already drilled 1/4 holes and now you want to open them to 1/2Get the drill bit centered in the holeStart pulling the trigger, use light pressure and keep the rpms upYou will not get stuck againIf you get stuck it is only because your drill bit is dullFor future reference use only drill bits made in the USAIt's a heat treating and drill bit geometry problem commonly found with Asian manufacturers which make their products inferiorFor drilling metal use 135 degree split-point drill bitsHigh speed steel bits will usually suffice for aluminumFor wood use 118 degree drill bits.
