Re: Home Built Puller

I built a puller using threaded rod 1/2 X 13 course thread. Not as powerful as I would like, but it did work. So I plan on changing it to 1/2 X 20 fine thread. If I take 20 ÷ 13 = 1.538 does this mean it will apply .538 % more force? In theory, the force increase is 65 percent. Frictional losses wi...

We took an old classroom bell and put a doorbell mechanism in it. Works well for a trolley bell.

Most of those bells are Jenkins units. I have one of their 10 inch fire alarm bells, and man is it loud. :D

Wouldn't some serious swings of a brick maul do the trick? :D

Re: Electric Bell

My company produces a 12 volt bell dinger module that works with single stroke bells, such as the clangers sold by Jenkins. PM me if you are interested.

Re: Happy Thanks Giving

That post offended me. I need a grief counselor. It was even more painful than brief exposure to a rebel flag. You think you were offended? You should have heard what my hemorrhoids had to say about it. Hope everyone has a good Thanksgiving. I was going to ignore the holiday, but I gave up and fixe...

Re: Temporary track

Good evening ladies and gents. I was asked if I could make a small loop/ oval track for 7.5" gauge for the holidays in the in-laws back yard. I was curious what has been used. Is 1/2" X 1" flat bar ideal? The price on flat bar versus aluminum track is almost the same (around $1.00/foot). I was hopi...

You've pointed out the one real advantage of Torx fasteners.

Re: Why People Prefer Imperial to Metric

You can put a LOT more torque on a Torx fastener than hex, phillips or allen head. Excepting Phillips, which has a problem with camming out when subjected to a lot of torque, the above is an often-repeated fallacy. Tests by SPS Technologies and others years ago proved that it was possible to torque...

The accounting department loves Torx. With Torx, the labor cost that goes into driving and seating threaded fasteners plummets.

Re: Time-delay Turnout

In terms of failure modes, we have a couple of junctions with manual switch throws and a long reach rod. A problem with this arrangement that I have learned, is that when one train follows another through the junction, and the first train is taking the right branch while the second is taking the le...
