perhaps you can heat the parts you glued just enough to weaken the glue so you can take it apart...
No reason why it shouldn't, if anything it should be better put together - on the subject, any ideas on why my milling doesn't look as pretty as yours?LeMaudit wrote:Very glad it worked! Well... mine better work too now
Yeswhy my milling doesn't look as pretty as yours?
This would also be better not glued yetthe cap doesn't have vents in it yet
Hmm... I would have to see the operations you're going to do first.LeMaudit wrote:It would involve machining a piece on the rotary table you already have, that you then would use on the mill's vise to cut your flats.
and... I'm supposed to figure it out myself by waxing cars and painting houses hint?Yes
pourquoi? If anything by attaching it to the endcap and to the first part it will give you somewhere to grip the part, right?This would also be better not glued yet
Fair enough. But don't bother heat and unglue. Just think now as a new challenge to make octagonal flats on a piece like that. It's a 10mn operation to cut perfect flats with all you have.I would have to see the operations you're going to do first.

pamplemousse.pourquoi?
True. But you may have concentric problems if you relate to a glued and very imprecise valve cap thread to center the piece. For the holes it's all right, but for the dimples, They need to be extra precise or the 0.03mm deep cut will show various diameters. Could be nice thoughIf anything by attaching it to the endcap and to the first part it will give you somewhere to grip the part, right?

Different speed, feed, machine rigidity (especially if he's using a different machine. Check your Gibs, though), tool sharpness, 2 flute vs 4 flute, coatings, lubricant, brass grade, tool length.jackssmirkingrevenge wrote: Part done, but I don't seem to have managed the same finish with the mill as LeMaudit, though I'm quite sure I repeated the same cutting operations... any ideas?
muahahaha... didn't see this one.can't get the chuck adapter off the rotary table - any special trick or does one need a "problem solver"?
As I know what tooling JSR have, I would limit that list to:Different speed, feed, machine rigidity (especially if he's using a different machine. Check your Gibs, though), tool sharpness, 2 flute vs 4 flute, coatings, lubricant, brass grade, tool length.
I bought some for aluminum... my wife can't stand the smell I also thought the odor what not that bad... women...I would use a cutting oil, like TapMatic (smell s great)
The stuff for aluminum is completely different; it comes (or came) in a silver can. The stuff in the metal gold can is for "everything except aluminum" and has an almost sweet smell. It's an old formula; I don't think it's available anymore.LeMaudit wrote:I bought some for aluminum... my wife can't stand the smell I also thought the odor what not that bad... women...I would use a cutting oil, like TapMatic (smell s great)
So you don't have to adjust gibs on Sherline machines? Damn...LeMaudit wrote:As I know what tooling JSR have, I would limit that list to:

JSR machine is factory new. They should be all rightSo you don't have to adjust gibs on Sherline machines?

The fins aren't quite perpendicular. I have to study the video again in detail.LeMaudit wrote:Okay okay.. I don't know I would say you could have cut moving the piece too fast into the end mill (I would not be surprised!), or rotating too slow (this would be surprising ). The fins don't seem to be perpendicular, is it a camera lens trick? Your brass looks very reddish.. are you sure it is not bronze?
I confess my piece was a bit polished too... for a photograph of the raw version, look at the "teaser" picture.

Also, the internal button will be right in the middle so careful not to drill it, and also to remove all the metal chips that will be stuck inside after the drilling. Removing the core would lower the button too much and you would drill through it, so you'll have to keep it there.
Granted, but I'm guessing you didn't have such guidance either so I have no excusesNot so big problems altogether, just unnecessary troubles due to... excitement
But that's perfectly normal My first experiments were without an audience, and I would certainly be much less proud about my first results.

I have more self respect! That's a result of the cooler effect. Go to a BBQ with a large-ish sturdy cooler, which will carry your beer and meat with some space left over. Invariably you will receive "can I leave my stuff in your cooler" requests from the less prepared which means that you tend to go home with freebiesThat's not the 5% alc 500ml $10NZD for four cans Bavaria is it?
...tough financial times since buying the lathe I see
The problem wasn't the chuck but the threaded adapter that allows you to screw it to the rotary table. The solution was a large spatula and a pair of pliers to improvise a horizontal screwdriver. Sherline, y u no make allen head?Yes, ramses if absolutely right: HAMMER!!!!
Seriously, you need a plastic hammer. just insert one of the steel rod in one of the holes (the upper ring) and gently tap.
Hmmm, need to go shopping.here's my personal collection of chemicals (there's an out of place item in the picture)
Cheers! That's pretty much what I didVideo
