My Precision Mathews PM1340GT Arrival

Mike, do you have the taper attachment, or did you just use the compound to cut the taper on the knobs?
NICE WORK.
Gives me ideas about making my own bolt knobs for rifles.
But now you made us all discontent with our plastic knobs that seemed to be fine before! HAHA.

Nice upgrades Mike.

Thanks Dan.

RIO, I do not have a taper attachment. I just used the compound slide set at 10-degrees for the taper on the knobs. This is kind of what helped me to make up my decision to make a lock handle for the compound as I was tired of reaching for that 3mm allen wrench to lock the compound between operations.

Thanks everyone for your comments. I really appreciate them. I also hope everyone is happy with their PM1340GT's and this thread and video have been helpful. I remember when I was looking at lathes back in late 2013/early 2014 there was absolutely NO information available on this particular lathe and it was frustrating. I also remember forum members asking a lot of questions after taking possession of mine which is why I did the first video. I wanted to make some information available for anyone else out there who may be looking at this lathe and was getting frustrated by the lack of information.

Thanks everyone.

Mike.
 
I went with a single pulley. I decided the low-end speeds were all I would ever need.

Running the VFD with this pulley and belt, it's running placard speeds at 50 hz.

Thanks man, you guys are awesome.

I noticed that the bases are already drilled and tapped for 1/2-13 for the feet. Not sure if this is something new, as I have seen pictures where guys have had to drill and tap them.
 
If you are going with a sensorless vector type VFD, you can use a slightly wider speed range and probably do just fine with a single groove 3.0-3.2" pulley running to the larger stock headstock pulley. This should give a speed range of around 50-1800 RPM using 90Hz on the E467. Some motors (like the Marathon BlackMax and BlueMax) maintain full Hp up to 2-3X their base speed/Hz, so you can use a smaller motor pulley and easily go to 120Hz or more. Nice to have such a wide speed range, I do this on my Pm1340GT, never been able to load it and see more than 2-3 RPM change in speed. Some information is here.

The 1/2-13 tapped hole may need to be chased with a tap first, it can be used for the feet, but I believe it is used for a bolt to tension the base if bolted to the foundation using the larger hole. Some bracing on the bottom of the cabinets or between them may be warranted as there can be some cabinet flex.

Yes, I chased it with a tap and it's fine now.

I ordered some of these to use as feet http://www.ebay.com/itm/221548097991?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT
 
Jim, if using the standard steel bases, I would use 6 leveling feet. Drill and tap 4 holes on the main (LH) column for 4 feet to support the headstock and use the existing 2 holes on the RH column. Someone here did this and posted pictures (REO I think). The 6 feet will help prevent flex in the base and reduce vibrations.

I have six feet on order.

Right now I have the lathe setup on the stock 4 feet in my garage while I do the 3 phase VFD conversion and motor swap out. There is a lot more room to work there. Once I get everything dialed in, I'll take it all apart, drill and tap the 4 feet on the main cabinet. Then it will all be moved into it's final place in my basement next to my PM940M-CNC. :)
