Starting a new job in any trade can be a nerve-wracking experience. There is a lot to know, and unless you went to trade school or technical college, most of what you need to know will be learned on the job.To help out, we talked to former lead carpenter and current Family Handyman set-builder Josh Risberg to find out what five things he wished he had known when starting out as a rookie carpenter.Get a Tool Belt and Load It UpFill your belt with the little tools \u2014 things like a scribing tool, torpedo level, speed square\u00a0and a small pry bar. Having all these on hand right away will save you a lot of time.\u201cLearn how to use them, too,” Risberg says. “Get familiar with them before you start, especially with the scribing tool. You\u2019ll be using that one a lot.\u201d Plus, the other guys on a crew will take you more seriously if you come prepared and do not have to borrow small tools all the time.Learn the LingoLearn the difference between terms like plumb, level and square. As a rookie, you\u2019ll probably hear these terms thrown around so much your head will spin if you don\u2019t have their definitions straight. \u201cSomeone will say something like \u2018plumb up the wall\u2019 and you\u2019ll be like, `What?’ \u201d Risberg says.Here are the definitions of those terms, in case you were wondering:Plumb: Straight up and down.Level: Straight side to side.Square: Two things coming together at a 90-degree angle.Be a Team PlayerLay out everything and think about the big picture. Houses are full of interconnecting pieces, so communicating and dealing with the people working on other parts of the project can prevent headaches down the road. Thinking, \u201cI\u2019m a trim guy, I do the trim,\u201d is the wrong mentality to have, Risberg says.Everyone working on a house is in charge of their piece of the puzzle, and if those pieces don’t ultimately fit together, someone will have to answer for it. Make sure that someone is not you.Understand That Houses Are Just Weird SometimesDon’t assume things are plumb and level, especially in older houses. Wood warps over time and things are not always built exactly as they are supposed to be. \u201cThe ceiling might be one height on one end of the room and a whole inch higher on the other,\u201d Risberg says. Basing measurements and lengths on the way things should be instead of the way they actually are could mean a lot of wasted materials and time.Study the MaterialsLearn the properties of specific materials, their strengths and weaknesses, as well as what material works best in which situations. \u201cThere are some things you\u2019ll only know if you go out of your way to learn them,\u201d Risberg says. \u201cLike, don\u2019t put standard MDF [medium density fiberboard] in a bathroom because the moisture could make it expand.\u201d Also, pay attention to details. If you need help remembering everything, take notes and review them at the end of the day.These five things should help a first-time carpenter get into the swing of things on the jobsite a little easier. There are other things that will help out, too. Show up on time, work hard, pay attention… these are standard qualities for anyone who wants to learn and eventually master a job. Combine those with the five “trade secrets” above and you will be working like a veteran trim carpenter in no time.
