Pretty slick. How well does it work?
Elegant. Simple. Good job of doing ones best to battle Murphy.
Very nice. I'm thinking that it is super smooth in use?
Countless little horizontal mills went to scrap because potential buyers couldn't visualize this.
Driving from the machine spindle infinitely better than placing that weight atop the fabricated spindle housing. And, still have ready use of the horizontal spindle. You say the bore is #2 Morse Taper; appears those are drawbar [not drift] holders?
Takes a few minutes to set up and align but other than that it seems to work just fine.
I haven't checked for run out yet but if there is any I'm sure it'll be from the Banggood collets and holder.
The over arm support is 2 1/2" for the for the horizontal spindle support so I turned the vertical attachment from 3" cold rolled steel.
The bearings are tapered roller bearings, L44643. I turned an extra fine thread on the top of the spindle for adjusting the end play and run out to zero with a special machined castle nut with a round collar that projects through the top seal.
I wasn't able to turn the bearing cup seats with the two sections welded together and was concerned about the weld pulling but with the wall of the housing close to 1" thick there didn't appear to be any distortion. Peening the short alternate welds may have helped too.
Interference fits for the spindle bearings as well as the bearings in the idler pulleys.
MT2 taper with a draw bar. MT3 would have been preferred but would have been too large.
Given my name, I have a vested interest in this question...
Why is it called a "Marvin" attachment ?
Certainly not an original idea on my part but it looked like a good idea for converting to vertical.
Nice solid conversion in keeping with the original machine, well done.
Well, I'll be damned. There's Klotz lubricants and Marvin windows and now Marvin Machine Products. I never realized all the ways my names are associated with the mechanical trades. Makes me feel good.Quote:

Because calling it a "Frederic" attachment just sounds dumb. Though I remain very attached to my horizontals...
Really nice build! Thanks for sharing!Quote:

2 years between placed orders hoping the harsh buyer feedback would've shaped up their quality issues. Guess not...
Link: https://www.youtube.com/results?sear...Collet+sets%22
The Collet holders: +/- 5 hundreds of a mm in runout (sic!) and non-coaxial to boot in all 4 cases...
Worse than the worn-down 3-jaw in the 50 years old lathe at work...
My only REAL LEMONS in a 70-ish item order history - too bad that would happen to "precision pieces"...
No biggie for me to regrind the ER32 tapers down to below +/- 2 thousands of a mm, tho -
about half of the ER32 collets in the (M & Imp) sets were in as bad a shape as the holders, too:
both non-coaxial and non-concentric when tried in the new-ground holder.
Finish was excellent, throughout - no rough edges, finely ground and clean
(others have reported bad cuts, rough edges and shavings within).
Even being cheap-to-the bone and given my 20-20 hindsight, I shouldn't have ordered them in the first place.
Guess I now have to shim their compressible saw cuts up, fit them in holder and regrind 'til "good enuff"?
-Yeah, right! Sub-6 mm collets just a piece of cake to regrind! "Happy machining!"
As per their original state - the bad ones are perfectly useless for my intended purpose.
-Why even pay for runout and non-coaxiality, when you could get that for free in a dirty, old 3-jaw? :D
Just my 2 cents & YMMV
Johan
PS: Perhaps the small collets could be honed? Another upcoming project/ waste of time?

Well that is interesting. It is amazing how many of these old manufactures have gone away.
Consider bedding them in low-temp alloy. Most are bismuth based, the low temp won't alter heat-treating or anneal what-so-ever. Plug ID with a stub of properly sized aluminum rod, so drilling and boring will be easy. Chuck the holder and dial in. These are educated guesses, certainly easier and more precise than 6 or 8 tiny shims...Quote:

The spindle run-out is negligible but I had turned the inside mt2 taper at the same time as the rest of the spindle on the lathe so I'd be surprised if there was any.
@ TM51: -Thanks for that (hitherto unconsidered by me) tip!Quote:

@glens5 : Bummer that BG hasn't shaped up their QC for these items during the years, and also:
their complaints department "didn't seem to fire on all cylinders", or was merely using a stalling strategy.
And then suddenly my "forthright and factual" review on their page got lost somehow...:)
Finally - after a tedious and tragi-comical e-mail chain I finally got my refund (less pp and local tax, tho).
Looking forward to perhaps eventually waste another fine 10 hours of grinding these "freebie" collet sets.
-See, it doesn't take much to make a cheap, masochistic hobby machinist happy!

I might call them Danggood.
From what's been heard here of Banggood, can only depend on that being a noise, after handful dropped on a concrete floor...
BangGood or Aliblahblah don't cross my radar often. My pop-up windows are a high percentage of women's fashion, or trolling for that squinky-eyed presidential candidate. I'm clearly not being profiled accurately.Quote:

Who knew?
I've found those Banggood Blue Nano endmills to be pretty long lasting and they're cheap (if you can hold metric diameters).
Nice job. I did similar in my youth had forgotten all about it!
a place I workd back in the mid 90's tried to give me a horizontal and a shaper. I had no way of getting them home as well as a 1 car garage... I wish i had got them. 3 years lator I built a 24x34' shop/garage 6 steps out my bedroom door. oh well I got a millport 9x42 around 2008 and a enco bench top mill around 2001. one free one for $500 pluss $100 to move the big one. I wanted CNC but you take what you can afford. like the new enco 9x20 lathe that was broken in shipping I got for about $200 that took me a day to fix then another day to get the enco out of it...all the gear shafts have a keyway sleve(built in key way on a sleve so they dont have to sleve the shaft I reckon) all of those were made offset.... what a effing wining noise all those gears made. I fixed them and a few other crap things and you cant hear it run now. not bad for a light duty 9x20. it's almost as usefull as my 7x14 mini lathe. but no where as stiff.I need to mount the 9x20 on a peice of granite.off coarse Ill have to tear it all appart and put the bed on my mill upside down and sqwuare up the bottom mounts to the ways first
I too have a lot of bangod stuff.chucks,end mills,carbides tool holders, calipers etc, but now days it's cheeper and faster on ebay.
Try aliexpress. Some of the stuff is very reasonable. Not all of it. As you say, some is good on ebay or Amazon. I shop a bit. Sometime 30 minutes comparative shopping allows you to save $10.Quote:
