Where the points slide back and forth, should I line this with some sort of metal or UHMW? Maybe brass bolts so the heads are just slightly above the top of the wood?
I would attach some strips of stainless steel to act as wear pads.

Re: Layout dye

As far as I know, there are two layout dyes available; red and blue. Is one color better than the other, or is it just a matter of preference? Due to a vision problem called tritanomaly , I can't see pure blue—it appears to be nearly black. Hence blue layout dye actually works well for me. :D As wa...

Re: iPad Photo editing software

It’s called Snapseed, and is published free by Google. Almost anything published free by Google would set off an alarm bell around here. What you have is likely spyware. Hey BDD, I usually enjoy your comments. We are all just trying to help each other out here. That’s why I posted my review. I'm tr...

Re: oilless compressors

As I don't live in America... May I suggest you put your location in your Chaski profile? If people know whereabouts you live they can perhaps offer better suggestions. :) As for oil-less compressors, you couldn't give me one. I've seen a lot of them fail with only a few hundred hours of service on...

Re: Trailer Features

I wonder if trailer tires aren't made cheaper than car or truck tires, and if you could put car tires on instead for longer life. Anyone know about this? Edit: Found an answer: https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=219 I used car radials on my single-axle race car trailer for ...

Re: Museum of Obsolete Drafting Technology

I still have some of my manual drafting tools from many years ago. Alas, I no longer have my log-log slide rule.

Re: LOUD diesel horns?

Some of the Baldwin S-12's have a long single tone horn on them that was reported to be 190hz. Measuring off of the Athearn model, it would be about 30" long in full scale, it's 5" long for my model at 1/6th scale. The theoretical pipe length for 190 Hz would be about 34.74 inches at sea level and ...

Re: LOUD diesel horns?

Just purchased a 12 volt horn on Ebay...inquired about the pitch...The response was 105 to 110Hz. 105 to 110 Hz seems unlikely—110 Hz is A2 on the piano. A locomotive air horn (aka "air trumpet") is acoustically modeled as a stopped pipe. The fundamental frequency of a stopped pipe corresponds to a...

Re: Sharp Corners

Pretty cool. I wonder if it would be worth the trouble in the future to make a mold and cast those braces. It seems you had to go through quite a bit of work to get to the finished product.
