New Lathe...Changed from PM 1127-VF To a PM1236

[precisionworks]

Filed & sanded for a tight fit

Really glad that worked out, Will. As you know, there was very little extra material left, something less than the thickness of a sheet of printer paper, and it concerned me that I might have taken too much off :thinking:

There's another way to tighten up a loose fitting T-nut, one that is sometimes used on a table saw miter gage. Drill and tap a couple of holes on one vertical face of the T-nut, and install allen head set screws so they barely project above the face. It isn't hard to set them so there's the correct drag. On a miter gage, the screws are set into the side of the bar:

replacement oiler

Gits makes them & McMaster (and others) stock them ... but the Gits oiler is nickel plated steel.

Guys,

do you know where I get buy a replacement oiler(it is a bronze looking thingy about 1/4" in diam. with a ball pushed up by a spring)? for my PM1236.

One of mine oilers lost it's the only ball. 🙂

Alex,

Call Matt, he's supposed to be getting some in if he doesn't have them already.

Anyone interested in some BXA holders? I have four that I just got from CDCO, three are for turning/facing (no groove), one for boring/turning/facing (with V groove). They're unused, I don't like them & will not be using them. I will let them go for $36 shipped, I paid $50 ($37 + $13 shipping) for them.

Will, Can I ask why you don't like them? I'm interested in the set.

Ditto the interest... As a backup!

Tool holders that came with my QCTP are not that great.
I appreciate if you guys can give me any recommendations (where to get, what brand etc.) on better quality holders.

I'm just not happy with the quality. I understand they are china holders but my AXA holders are much nicer & the BXA holders that came with the new lathe are even better except for the long *** screws. My AXA holders are also a tad longer than these BXAs. Not sure if that's the standard length for BXAs as the only other ones I have are much longer than normal but no big deal.

The adjusting collars are not consistent, not threaded straight so they are lopsided as they are turned. I never seen holders that have the dovetails coated black too, I'm used to the ones that are ground after being coated black, again no big deal.

The set screws are cup points. I don't like my tools to be dug into that much using cup point screws. I could modify & replace parts but not worth it, but what do you expect for $9-$10 holders. I'd rather just pay the $5 - $10 extra to buy ones that I like. I'm not going to try & return them as Frank at CDCO sucks to deal with when it comes to returns. Took me 3 months & 5 calls to get a $20 refund which was not worth the effort.

If you guys still want them please let me know. If not I will put them on ebay. 🙂

If you want better quality than that, you'll have to buy American like Dorian, Aloris, Armstrong, DTM, etc.

Another question...

I have a surface grinder.
Will any parts of my PM1236 benefit from surface grinding?

I have relatively small magnetic chuck on my surface grinder so I can grind only parts that have footprint not bigger than 10"x5"

Thanks

Average quality holders seem OK on an average quality toolpost ... when the toolpost is the Dorian SQCTP, nothing fits as well as a Dorian or Aloris block. I was not unhappy with Chinese holders until I started using the Dorian.

blahblahblahblah.....ah what's the point, can't avoid trying not to hear you as I'm reading it.

Man Barry, don't tell me that. I've thought about purchasing Dorian holders far too many times since I picked up the SQCTP but I really don't want to spend that kind of money on holders now or later. A very mild hobbyist like myself probably would not see any benefit in using Dorians over the China ones.

Good thing your "encouragement" was too late for Enco's 20% sale (EDIT: I forgot ENCO doesn't carry very many Dorian products). Well there's always the next MSC sale......

I need to pick up a number of holders for the tooling I have now...."can't afford Dorians, can't afford Dorians". Ok I want some now.

Ah never mind, I'll just keep them a make some new adjusters for them.

Will,

That Dorian looks real nice. :twothumbs

I wonder if anybody ever adapts a handle to the lock down nut to make rotating the QCTP a little easier/quicker 😕 Seems like I am always tweeking it to cut a chamfer on workpiece, maybe I should dedicate a holder and cutter with the angle I want.

Thanks Ray, I'm very happy with it.

Actually Dave (saltytri) did that to his DTM: http://www.candlepowerforums.com/vb/showthread.php?p=3144421#post3144421

Beautiful job well done too!

Looks very covenient but I'm happy using my big old Armstrong wrench so I can really crank down on it. 🙂

Barry, I couldn't have asked for better. The length & width of the blank T already matched my compound slide good enough. For the top width you milled I only needed to file off roughly 2-3 thou off & it was a perfect fit.

I started of by lightly filing the inside surfaces of the T slot on the compound slide with a single cut mill file to remove any high spots. Bought a brand new file for this so it was nice & sharp. Then I lapped the bottom of T nut with 100 grit or so. Then using the same new file (back side of it is double cut *******) that I bought & filed the recesses on the T slot until it came close & used the single side until it fit they way I wanted. Ended up having to remove about 4 thou. If I did not remove most of the high spots inside the T slot I'm sure I would have had to remove more off the T nut.

So as you can see it was job well done which saved me from excessive labor. :twothumbs

 

[precisionworks]

Good approach to file the slot first, I didn't even think about that :sweat:

+1

My "toolpost wrench" is a 1/2" square drive ratchet handle with the socket that matches the Dorian nut - which is the same size used for the mill step clamp nuts. It's just to the right of the BFH with the orange handle :nana:

Really hate to see this one go but just in case anyone here might be interested before throwing it on ebay, I'm selling my 5" Bison 6-Jaw Set-Tru chuck with adapter to fit the HF/Lathemaster 8x14. Unless someone wants to buy my entire 8x14 set up with this chuck I'll give you a great deal. Local only though for the lathe.

I got the chuck used & I purchased brand new replacement jaws for it. The jaws were manufactured last year as I had to wait 3 months for them to get made in Poland. Also includes a Bison chuck key which I purchased new & the old jaws.

Chuck cost $1050 new & not many places carry it. MSC & Enco do not carry them so getting one with a discount applied is not likely. MSC does carry the 5" Bison D1-3, D1-4, & threaded Set-Tru adapters in case someone is interested in fitting it on a different lathe.

PM or email if interested. CPF members always get first priority & the better price.

Your best best is probably a NEMA manual motor starter

Thanks again Barry for the suggestion. I got a Square D 2510KG2 on ebay for $20. Simple yet effective for exactly what I wanted.

New lathe looking good 😉

What type/brand is the chuck in the TS?

Thanks Will, much thanks goes to you. :twothumbs

The lathe is equipped with Bison chucks on both ends.

It's a Bison like Barry's except 5/8" size. I just threw a bid on it not expecting to win as I was broke that week & got very lucky, $56 new shipped.

This is the first "real" chuck I've ever played with except for the keyed Jacobs in shop class. On the 8x14 I had both 1/2" & 5/8" China keyless chucks in both standard & "CNC" versions (can't tell the difference) & the Bison is so much smoother & grips so much harder. Yesterday I snapped a HSS center drill while center drilling some Ti, it was the only thing to give way. Wonder what would have happened if I had a mishap using a carbide center drill? :thinking:

I originally was going to get a 8" Pratt Burnerd 6 jaw but I ended up changing my mind at the last minute & decided to keep with "tradition". 😉

 

[wquiles]

Ahh, very cool. Bison chucks on both sides :twothumbs

I just installed the keyless Albretch myself last night, so I have not used it yet, but I look forward to keyless operation as well :thumbsup:
