** Note: HP laser printer drivers on Mac laptops may not print at the needed 1:1 scale, no matter what software you use or what you do in the print settings. Exact same file, printer and Adobe Reader are able to print at 1:1 scale on a Windows laptop. There might be an issue on Macs. | ** Note: HP laser printer drivers on Mac laptops may not print at the needed 1:1 scale, no matter what software you use or what you do in the print settings.

** Hint for Onshape users: You can import a pdf page via Inkscape. Import the pdf page in Inkscape and save it out as dxf v14 file. Import that dxf file into Onshape. Start a new sketch. Add the dxf drawing to the sketch. Take a known distance between two points and call out a dimension between them. It will show the distance as it imported the drawing. You can now override that distance to the known distance and the whole dxf is now at scale. You can now overlay your own drawing while the endpoints will snap to the dxf points. Next, create a drawing within Onshape and add the sketch. You can then export that drawing back to a pdf and the scale is correct. | ** Hint for Onshape users: You can import a pdf page via Inkscape.

** Consider drilling this hole using a 3/16" drill bit which is just a tad smaller than a #12. You can always enlarge later if necessary. If there is any looseness in this hole it may cause the stick to be loose as well. | |||
**The photo shows how far you can get the WD-1012 into the WD-1011.[[File:WD-1012 inserted into WD-1011.jpg|thumb|End of WD-1012 as seen from the inside of the WD-1011]]If you use a Dremel with a grinder attachment you can very carefully smooth out the interior of the WD-1011 allowing the stick to be inserted further into the steel tube. | |||
* Step 4: Don't force washers in and make sure the control column doesn't have play before tightening the bolt. Consider adding [https://www.aircraftspruce.com/catalog/eppages/continentalnewwashers_07-06527.php 1/64th thick washers]. Make sure that after tightening the second side down, no binding can be felt from the bearings that might have taken on side load. You may need to deviate from the instructions in terms of the sizes and numbers of washers on either side of the bearing -- just make things as centered as possible with zero lateral looseness but not too tight, either. | * Step 4: Don't force washers in and make sure the control column doesn't have play before tightening the bolt.

** It's OK if the AN4 bolt is a bit loose inside of the brass bushing, but you need to properly tighten the nut on the AN4 bolt. It should be torqued to spec but without distorting the steel parts. The brass bushing should be firmly situated by the AN4 bolt and should not be able to rotate. | ** It's OK if the AN4 bolt is a bit loose inside of the brass bushing, but you need to properly tighten the nut on the AN4 bolt.
