Mini Lathe Multiple Banjos Single Point Threading

[jjr2001]

Sorry about that Paul
One more click and I would have pasted in the link..He He.....
I hate it when that happens!!!

Here is the link for the 2:1 belt drive gear reduction missing from the above post.
HTD3M 48T 24T Belt Width 15mm Timing Pulley Belt Set Kit Reduction Ratio 2 1 | eBay

They have a wide range of belt widths and pulley dimensions. I think the 2:1 is a good starting place.



There are two PDFs on this page for mini lathe speed reductions. Pretty close to what I was thinking of doing to mine. Ralph Patterson plans

The 80/20 and 80/20 factory setup is about 256 tpi I believe. That is what I have on the original banjo. That info was from VarmitAl's site: http://www.varmintal.com/alath.htm#Finish
Which is another great mini lathe site.

All of the other new banjo gearing is the same as shown in the manual and the threading chart on the head stock cover.
Only one banjo is used at a time so my feeds are exactly the same as stock. However gadgetbuilder's slow speed banjo is much slower but I am not sure of it's speed.
