Just had a quick look at my lathe...

Metric 1.5 pitch thread uses 45t as driving gear and 60t as driven gear. Ratio 1:0.75

Your lathe uses 30t as driving and 40 as driven. Ratio 1:0.75
...

Can't really help but...


I would have thought one of the idle gears was on some kind of banjo arrangement?


The only gears that matter here are the input and output gears. Assuming 30t @ A...

What am I supposed to be doing exactly?

I can tack things together, everything looks okay to me and nothing seems to fail but I don't pay any attention to much else.


For example when the base...

Not too sure about this one, it's advertised a little bit wrong. States that you can use all 8 corners but you can only use 6, still need another holder to use the other two. Also claims that MCKNR...

Haha... Not if you load the whole edge up:wink:

Seriously though Ireferenced the SCBCR and SCKCR holders in the CCMT thread. They definitely come in handy and I use them heaps. Having a completely...

Is there much difference between the two in use? The 'M' AND 'G' denote accuracy with 'G' being the more accurate of the two. I guess it's just a repeatability thing??

No worries. Yeah nice to have one but not a necessity, a couple of cheap vernier scales would be good enough for a lathe if you were that wayinclined... The mill on the other hand, now that's a...

Finished cut...

For some reason I can only upload one pic per post?? Anyway, setup for the cut...

Ueee, hand fed cut, one pass 41XX, quick and rough setup...

Diameter = 9.31mm

D.O.C = 1.15mm

Target Diameter = 7.01mm

Actual Diameter = 7.025mm

Looks good to me Ray, finish looks okay to for MS. I wouldn't have thought 1.5kw would be that easy to stall. I'll put up a vid on some harder stuff latter if I get some time.

Yeah i'm not really game enough to hook into it like that, everything's going pretty fast. I wonder how many people have come to grief over you tube, lol.

Okay here's the vid. I'm not laying into this cut, only one hand on the lathe the other leaning over it trying to film, with two hands on the wheel i'd push it harder. Still gets a bit of color as...

Thanks Ray, vimeo, never heard of it. You tube wouldn't work for me. Video uploaded I'll put a link up shortly.

Using the lathe today and remembered this post so thought i'd drag it up for a little more comment. CCMT inserts, 8.5" x 16" lathe, 10mm tooling, cold rolled bar, 5.25mm cut!!! Can't take much bigger...

Before I get too far into my design.#I keep looking for some other kind of support but from what I can tell the gantry is held in place mainly by the ball screw and to a lesser degree the bearing...

This one looks much sturdier than some of your others. I've been scouring the web and come across the same dozen or so pages a dozen or so times and read heaps of builds, I think your builds are some...

You've built some awesome machines Rod. After reading this and a handful of your other build threads I've decided to have a go at building one myself. You've inspired me!


I see in your older...

Hi Rod,

Nice build, I found this thread pretty interesting.

What machine did you machine the ally on? And what is a machine like the one in this thread capable of?? #

Thanks for the answers guys.

Andrew, I'm not using a vfd either so what you've done sounds good.

Hey guys. Just working out what I need to get started on a mill/drill conversion. No problems with the mechanical side but not real sure on the electrical side. Outside of a few pics and a couple of...

My thoughts on the matter... If you were going to build a bench mill there's already heaps of small bench mills that fit the bill. If you were to build a knee mill it would be to get a more rigid...

Long Chang Machinery Co - #Model LC-15A.

Same as RF25, Jet15, etc etc.

I didn't think it would fit at first. There's plenty of room, so yes I will just mount the reamer in the tailstock.

Smarty... I was singing#:)

I'll remember that though, thanks, I've learnt today, lol.

You could be right, it was made in 1980 so someone could have mounted the wrong taper at some stage. I could be wrong, it might not even be a morse taper and that's what's caused the problem. I...

Thanks. Bit of a choir getting a pic up, took me longer to work that out than it did to pull the spindle out!!

I have#a round column mill/drill of the RF** type.#The taper in the spindle is stuffed, heaps of gouges, when you insert an mt3 it only contacts in the middle and rocks back and forth. The taper in...

If you're up for a bit of reading and a little math#http://nachi-tool.jp/bearing/pdf/Tech.pdf

Bearing life is as you say done using a simple formula. Operating speed, operating temp, diameter, type of bearing and quality are used to gain the working hours of the bearing. There are also...

Mate that's what I was taught, take it or leave it, doesn't bother me either way.

It's kinda the opposite of that. The jaws are self aligning so one or more of the jaws will be under strain when tightening the workpiece.

I was taught the same thing. Never use out of round stock in a three jaw chuck because it damages the scroll.

Lol, yeah them girlfriends and their bloody cats!

I guess you've heard the saying . . . A dog looks at it's owner and thinks you feed me and look after me you must be a god . . . A cat looks at...

How did your welds go? Didn't blow too many holes??

Good on you for doing the right thing. It should be law for anyone who keeps cats to keep them restrained in an enclosure.

A plank of wood with a light gauge wire forming a curve sounds like a...

No worries, glad you found it interesting. Hope u don't mind if I put a couple more links here. Some of these watches fascinate me, complex little machines that run 24/7.

Belt Driven watch.

Very interesting, just need to sell my house to own one, if I start making one now I might be finished in 10yrs.

There's lots on the net about watchmaking but here's an interesting one on engine...

By reading the page in the link provided one would think the printer also created materials out of thin air.

No that's okay. I've only sold a couple of things so it's all feedback to me. I wasn't aware that someone could make their feedback hidden it kind of defeats the purpose.

Vernonv... I think that's...

Besides that you can just tell when someone's not being straight down the line.

First thing, taking four days to get in touch. Second, asking for a phone number when I've already given it to him....

Mate it's a two way street there, I had to arrange my work schedule around to be available at any time during the day and this way conveyed to him. He's got my phone number it's just common courtesy...

What would you experienced ebayers do??

Someone bid on my item and won but didn't make contact for 4 days, when they made contact they asked if they could pick it up today and requested my phone...

I'm just wondering... so there's no need to level it then?

Does a granite plate that thick flex? Could you just drop it on polystyrene and let it level itself?

I reckon he'd take anything for it atm.

That's funny. Im old enough to remember not having mobiles and computers but my kids are out of control. To be honest I didn't know they existed until my daughter showed me a couple of days ago.

What do you want from a $1500 dollar lathe? Maybe that's more direct.

Im not trying to be harsh but in the scheme of things in this day and age a couple of grand isn't much. When you get people...

What I was trying to convey is that you cant catch a shark with a spool of cotton and a toothpick. If you could turn #### into gold we'd all be rich.
