The Home Machinist!

This information is being placed in the Resource Library for future use. I have taken the time to expand and explain the Point Load based on Rail Size and Tie Spacing. Formulas are included. Good Luck, Terry Point Load based on Tie Spacing and Rail Size Update ver.2.pdf Tie Spacing Chart 2021pdf.pdf

I have been asked to explain some terms/items and post in the Reference Library for posterity. I hope changes made will make these easier to read. I added rail sizes not available today since many of us use what we can find. I own some 10lb rail. Thank You, Terry Point Load based on Tie Spacing and ...

Glenn Brooks suggested we place a copy of the Tie Spacing Chart into the Reference Library. I reworked the Chart and added an Information/Explanation Letter. I am posting it here to see how it posts and to get feedback on the new Chart and Letter. I welcome your input. Thank You. Terry Rail Spacing ...

Glenn, Thank You Very Much. I appreciate all you have done. I will check my computer and see if the chart is in a .pdf file or if it's in something else. One NOTE I wanted to add and never have YET: The S section modulus for the formulae is the second column Modulus of Elasticity. So ALL of the info...

Glenn, You are correct, this chart is based on the original. The exceptions are as follows: Erroneous data has been located and corrected, data has been researched and added, information has been added and explained. Using this chart and formulae, anyone can find tie spacing and rail size to suit th...

Richard is correct. I even see this phenomenon occur in hydraulic crane booms. The side the sun is on will expand and bow the boom away from the sunny side. This is taken into account when they engineer the booms. As for naval machines, the most critical items are the propulsion components. Alignmen...

Russ, Thanks for the quick reply and information. The pulley I need is for the saw arbor and as far I have searched and been told, is not being made any longer. Thus, I have three options: 1. Use the one I have with three belts, 2. Keep looking for someone parting out or selling an old saw same as t...

I see the last post was in OCT. 2020. Doesn't seem to be a whole lot going on in this part of the forum. I have a Powermatic 4 groove B-Belt sheave/pulley I would like to replace. No longer available from Powermatic nor can I find one on the auction site. I am looking for a machinist to turn a new s...

Glenn, Think gas engine powered air compressor. When the tank reaches design pressure, there is a cut out that allows the engine to continue running, AND the compressor still compressing but now the air is just discharged and not put into the tank until the tank pressure decreases enough to kick in ...

Wheel weights are Zinc or Lead if they are "clamp-on". They can be Zinc, Lead, or Steel if they are the stick/tape on types. Most, NOT ALL, clamp-on Zinc weights are coated with a sealing material such as a plastic compound. Lead weights can be plain or coated. The easiest way to tell them apart is ...

Mike, If you can, take a voltmeter and check for voltage between the welding lead plug-in sockets (if you have plug-in leads). This should tell you if your primary side is working. You may be having trouble with your leads and/or stinger and ground clamp. Loose or corroded or just plain dirty. If yo...

Hello Dave, I would like to make a suggestion. While not as readily available as 12 lb. rail, there are both 8 lb. and 10 lb. rail around. 8 lb. rail being more common and last I checked still available new, might serve better on a dual gauge/dual scale railroad. Both would be plenty strong enough f...
