Re: Oil fill mark on presto 8dg?

I would just to look at it and see everything is good. But you also have to be pretty careful in there with the ge...

Re: Presto 8dg refurb. (Lathe porn)

man those Bodine Motors are nice and quiet compared to the one I'm using, too bad they run at the wrong speed here in the UK. Did you have to dissassemble the gear box at all to service it? When i first purchased the unit i basically had to do a full tear down. I actually wish i had taken it a litt...

Re: Presto 8dg refurb. (Lathe porn)

I posted a video of my machine running all 3 speeds for comparison to another lathe that's experiencing noise and rumble. I thought the video would be useful to other people so here is the link.

Re: Affordable Lathe For Beginner

If i had it to do over again, id just get or construct an overhead, buy a nice TT and then search for a head.

But even that will break a thousand pretty fast.

Re: Presto 8dg refurb. (Lathe porn)

I'd recommend a hole punch set, super handy when making your own neoprene slip mats and in cases like this. https://images.homedepot-static.com/productImages/c17395f5-0bd3-48ee-a65d-c6581e9473b4/svn/tekton-punches-nail-setter-sets-6588-64_1000.jpg Awesome.

Re: Presto 8dg refurb. (Lathe porn)

Dang. A cored out guitar knob is a great idea for a record clamp!!! Never even considered it! Perfect for anyone with a k8, 8dg, 75a, etc. just ordered a few knobs! At first i was trying to reinvent the wheel which almost worked. But i saw some photo's of a few chucks that looked like a guitar knob...

Ametek lamb shut down?

Well, i built my vacuum box from an ametek lamb unit. It works good all for about 15 mins, then shuts off it seems. I know that these units should not run at full voltage, and mine is not, it runs at about 91v due to a transformer trick. The motor was repaired however, the spindle was damaged with o...

Re: A simple and inexpensive stereo cutter YOU can build!

Yes sir. I need some kind of pitch control, as mine was absent from the lathe when i bought it. Now lately i have been thinking of just using a motor on a pwm controller with a couple preset l.p.i. buttons to start with. Sounds like that might be fine for what i plan to cut (rock/electronic). I migh...

Re: Presto 8dg overhead only hand cranks?

Both are off the shelf toorhed pulleys from ebay.The one attached to the overhead i had too bore out the center a little bit to fit. My pulleys disappeared before i got to the machine.

Re: Presto 8dg overhead only hand cranks?

Hi everybody! So i got the l.p.i. motor mounted and moving the shaft from the overhead into the lathe cabinet. But the worm gear doesn't move the overhead carriage. If i use the hand crank, it works. Inbetween the handcrank and the overhead is another locking collar that moves with the l.p.i. motor...

Re: Presto 8dg refurb. (Lathe porn)

And i made v2 of the air chuck. Much better. I cored a guitar knob out to fit the spindle of the platter and a small copper tube. Works much better. I kept the set screw and leave it close but not touching the spindle. Now i can feel the vacume pull the lacquer. I also added fans and a controller to...

Re: Presto 8dg refurb. (Lathe porn)

No problem. Thanks again for all your help So the 3 terminal resistor is 50 ohm at the connected terminals. Taking a measurement on the third disconnected terminal gave me 100ohm. So they are using it as a 50ohm. The second resistor gave me .4ohms no matter how i placed my leads. That doesn't sound...

One on the mount arm that throw arm for the puck and another next to the 40uf 240v cap. Looks like a black selenium rectifier, any numbers or values - I think I can see EDI PRS I...
