Line shafting
 
Hi everyone,

I am in need of some line shafting but can't find any for sale.

Is it possible to make something simular? And how much would it cost?

Thanks in advance

Easy enough to make, some steel bar from a steel stockist or scrapyard, a few pulleys of various sizes and some steelwork and plummer blocks or similar to hold it all up! As to the cost, I expect most of it can be sourced at rallies or on t'internet either new or used if you bide your time and not want it all yesterday?

Pete.

that's brilliant, thank you.

I have found some bits on ebay that should work, but what size pulleys should I be looking for?

I'm sure folks would like to be able to provide more help, but this is another "how long is a piece of string?" Question. You need to give us some idea of what it's for, portable or in a building, run by what, driving what?

I think that generally the line shaft is likely to run slower than the crank, so a pulley bigger than the one on the engine. Then probably smaller pulleys for the driven, but really you are going to have to design this for yourself...

To calculate the required pulley size some maths is inevitable, and pi may even raise it's ugly head. If you let us know the desired RPMs of the engine and driven machinery, we can tell you.

You can leave pi out of it Mark; it's a simple ratio thing...

Phew, thanks Martin :smile: that is a nice shortcut ! I was using circumferences.

My dynamo pulley is 3.5" diameter and the dynamo needs to run at 1300 RPM (3.5x1300=4450). The IP pulley is 10", so the IP needs to run at 445 RPM ? Does that sound right ? Its governed speed is 430, so that is pretty close. Best way is to try it, I suppose.

That sounds right.
