Portland Streetcar Finishing Tip 2 - End Section Corner Posts Modification

Hi All,

We ran across a fit-up issue for the operator's cab side wall glass and thought we would pass along a fix.  There is a blob on the inside of the corner posts that prevent installing the side wall glass.  One way to resolve the interference is to remove the blob with a small chisel.  Be extremely careful as the corner post is thin.  Tony used a fine Dremel burr and groung it out.  I am not practiced with a Dremel so I stuck with a small chisel and took my time.  See the pictures below.

This picture shows the blob.

In this picture the blob has been removed from the cornerpost.

Just another small step, get all the flash and fuzz off.

Portland Streetcar Finishing Tip 1 - Straightening Warps in Castings

Hi All,

Here goes with the 1st Portlabd Streetcar (PSC) Finishing Tip.  I am the first to admit a lack of experience in working with resin castings.  I have worked with epoxy castings but they at a different animal.  But not to worry, my associate on the PSC, Tony has been warping, twisting and otherwise coaxing resin castings into shape for quite some time.  They always seem to have some waves and wows so here is an effective way of correcting them.  Experiment until you get the desired result.  Keep in mind that a second soak may unlock the last correction made.  The advise he offered is;

  • submerge the warped portion of the casting in hot tap water,
  • wait till it is heated,
  • remove the casting from the water and weight the affected zone until it cools,
  • finally, remove the weights and you should have a greatly reduced warp or wave.

A Follow up on Type 5 Lighting

I thought I would offer a follow-up on the last post on Type 5 lighting.  This is a link to you tube that shows the car and lights in operation.  The headlight is not as bright in person as the camera captured.  You can see the interior light bar from a low angle when the car passes by near the end of the clip.
