Another place-holder while I do something else

OK this is just here to have an actual daily “something” here to attract attention from the bots that eventually read and classify everything on this blog for search engines. What I’m going to do after I finish this place-holding post is make a structure from the rods to get more practice with the file method of generating a cope in the plastic rod, more practice in getting a decent close-up from my phone camera (I should probably invest in a macro lens for said camera), and see just how rigid a structure I can build using the styrene rods and sheet.

OK now off to practice creating things from plastic shapes.

I found the files

And I used one to make copes in the rod I’m using to represent the tubes of the frame. I need more practice, but I got one that fit well and looks almost like the 1:1 Sprint-T will look when completed. Now the 1:1 car will use tubes of different wall thickness for areas of the frame that are loaded more or less with the wall thickness adjusted accordingly, but since they are all the same OD but different ID I use just the one size rod for everything on the frame. That is the same stuff I’m using for practice because I have tons of it, and I need to get those joints as close to perfect as possible.

This is the leg that had the cope that was better then the cope on the other side. The joint in question is the one on front and to the right of the picture.

Now the joint is in front and to the far left. You can see the fit of this side is not as tight as the other.

Not much to say except I used the back side of a triangular file to form the cope and the melting effect of solvent plastic cement finishes the actual cope when I force the joint together. Once I got it down it worked surprisingly well. The second try worked perfectly and also auto-aligns the joint to the center of the vertical member, or whatever orientation the coped rod is forced against.

In other news Mrs. the Poet’s new vacuum cleaner sucks, and that’s a good thing because that’s why we got rid of the old one that stopped sucking, sucking up the dirt. She made a test run and then did the entire house while I was doing my first search for the hand files. She is much happier to have a vacuum that sucks again.😁
