Good evening, Finally found time to commission the long travel stepper motor drive on my SL. The controller fitted has several useful functions other than just backwards and forwards but I'm having trouble with the auto-translated instructions. Also tidied up the 4-way lighting set-up. regards. David

Re: brazing broken teeth of 3-jaw chuck
UNSAFE TO DO SO. BIN IT !

Hello,

I wanted to ask your advice.

Unfortunately, the 3-jaw chuck slipped out of my hands and fell to the ground. From the hit to the jaw n. 3 broke 3 teeth.

Luckily I had another original 3-jaw chuck but I would still like to recover this broken one too.

Initially the idea was to make a small hole (0.5mm) on each tooth to insert a small harmonic steel wire to be inserted into an adjacent hole directly on the jaw. This is to have a support for brazing with castolin 8103.

Unfortunately I was unable to drill the steel of the tooth. At this point the idea is to braze directly by inventing a way to keep the teeth in position while I heat the piece.

Have any of you ever experienced something like this. Do you think brazing can hold up?

Re: Baseline / empirical testing Unimat 3 lathes and milling attachments
Peter, In general these lathes get very little use and suffer little wear so I doubt you will experience any excess runout. Lathes are inherently accurate. If course gib strips etc might need slight tweaking to ensure smoth operation and lead screw handles adjusted to minimize backlash. If you really want to check for wear in the bearings you will need a precision ground test bar and a dial test indicator with mag base. May I ask what you want to do on the lathe ? If its clock making then you likely need the precision but other than that i doubt you need to be so strict with your tolerances ! It depends on what your end goals are, but if your new to the hobby just have some fun for the time being. Kind Regards, Paul.

I didn't quite know what to call this post so I hope that is not too far off the mark...
Last year I acquired two Unimat 3 lathes and two milling heads. Once the workshop warms up a bit (not too long now hopefully!) I want to test them out to find out which set is the better (and sell the other).
What tests should I run? I'm guessing turning something and testing the runout will be one thing...
I have Emco three and four jaw chucks, an Emco ER16 collet chuck and will soon have collets with a specified runout of 0.005mm to 0.015mm if these would be of use in testing.
One of the lathes came with a manual and this has (handwritten inside) the part numbers of headstock bearings, so these may have been replaced on this item (or not, of course).
Any advice gratefully received!? Excuse my ignorance but I'm totally new to lathe work (and high accuracy metalwork in general :)

LOL $11 does that include postage and shipping and import tax i wonder ! At that sort of price are the pages of the magazines made from Gold Leaf ?? Ain't buying that. Thanks for the help guys but I guess its back to !

Re: Unimat Mill/Drill Mounting System ?
Mounting is by two bolts through the column and into the lathe body - the rear of the lathe body has a curved recess, the female to the column's male.
What the column does lack is any sort of keyway to keep the milling head in the same alignment as it is moved up or down the column. I have seen youtube videos of milling a keyway into the column, which seems like a sensible idea.

Re: Rustoleum Green Hammered
Hi James,
I live on the other side of the bay from you; while my SL still has great paint, let me know when it becomes available, as I'd probably take at least one can as "insurance".

Re: Rustoleum Green Hammered
Hi
Gang:
This
somewhat reminds me of when I bought my Granite Smithy
Lathe/Mill. I called Smithy and asked them about factory
seconds. They said they had a machine at 33% off, but it was
blue and not the standard gray granite color. I said blue
would be fine. Bought chucks and collets with the difference.
Blue still looks fine.
Carl.

This small hardware store has Verde Green:?
I was just at my local Home Depot two days ago and they were closing out both Rust-Oleum the Hammered Gray, and Hammered silver spray paint. Reduced to $7.60 from $10.48 I don¡¯t know if this is happening all over. Kit Maira Support the Cause of Peace

Hi John, I know for sure that the paint you require can be purchased in the peruvian andes from a local paint shop. However they do not ship to the USA. Also its costs 3 baby lamas and an incan poncho in exchange for just one can ! Let me know if you need the address as you will have to fly there to collect in person :D

Attached for information is a copy of the color chart that Rustoleum just sent me.? ?The Verde Green is probably the closest to the traditional Unimat green.? But find it.? I went to my True Value hardware.? They checked and found no suppliers(otherwise a few cans on Ebay for mid $40 shipped one can.? These do not exist for me).? So it you want to use hammered, the silver and gray are the closest to the color used on some Unimats.
As I said before, we keep beating the same old horse. It is always that some magic paint store will make it, or it is in another country and unshippable, or I will check, or someone online shows you how, etc.? Just tell me that I can buy one can from so and so.

Unimat Mill/Drill Mounting System ?
Hey guys, I'm not sure what version of the Unimat I'm thinking off but like the recent Unimat, I think it was a Unimat 3, that sold on E-Bay for @ ?600 which included the Mill drill attachment and motor. I'm curious how it 'fixes' to the lathe bed ! From what i could see it appears to be only two bolts but i would have thought some form of key-way or guide pin for alignment would have been used to ensure 90 vertical to the bed in both x and Y axis. The reason i ask is I'm curious if a similar attachment might be used on a Sieg c0 lathe.

Re: Rustoleum Green Hammered
That product is not shipped to the US. Thank you though.

Re: Rustoleum Green Hammered
You are right! I'll see if I can find it on another site and maybe buy it and try it! As soon as I have the link, I'll post it here.
