Re: Issues with DRO on Midas 1220 LTD

Do you ever have issues with coolant or chips on yours in the front ? No, it's been fine. Mind you, I am using a glass scale with a double lip seal mounted so the read head on the underside. Pretty hard for anything to get at it. https://picturehosting.verhey.org/hq800v/Y-scale.jpg The other advant...

Re: Issues with DRO on Midas 1220 LTD

Funny. I started with my glass scale on the tailstock side, and moved it to the chuck side. I don't have to extend the tailstock as far to reach over it.

I also have an aluminium angle guard over things.

Re: Smithy granite

Without considering the merits of one specific brand over another, the 3 in 1 format is suitable for a hobbyist on a budget and/or in limited space. I have used mine for making unobtainable (or even difficult-to-obtain) parts for motorcycles and outboard motors that I am restoring/repairing. Even mo...

Re: Smithy Midas 1220 LTD Quick Change Toolpost Help

As I said, I don't have a Smithy, so I can only imagine without pictures. An oval can be turned with the lathe if you have a 4-jaw chuck. You start by turning the piece to the diameter of the widest point of the oval, then offset the piece in one direction to form one side of the narrow part of the ...

Re: Smithy Midas 1220 LTD Quick Change Toolpost Help

If I understand correctly, the bolt that came with the QCTP is too large in diameter for the slot in your compound? If so, I faced the same problem when I fitted my QCTP to my machine. Although it was not an AXA nor a Smithy, perhaps you could do as I did and turn the new bolt to fit the slot instea...

Re: Grizzly 9729 half nut

Acetal and Delrin are very, very similar. Same chemical structure, different manufacturing process (IIRC). I don't think it makes a big difference in this application, but I might give acetal the nod here over Delrin. Here's a short summary of the differences: http://www.lionep.com/uploads/files/Ace...

Re: Grizzly 9729 half nut

I played with it a little bit last night but was wondering if anyone else has any experience with this material. More importantly will this material hold up or should I complete the tap and make one out of brass. I've read the same method of making a delrin half-nut, and considered doing that mysel...

Re: 3-1 Machine purchase, what to get?!

I've never seen the Bolton in person, so I googled it. From the specs and a youtube video I would say it is pretty typical of the type. It may well have been made in the same Chinese factory as the Craftex B2229. The two are very similar in size, with slightly greater swing over bed offered by the C...

Re: Thread Gearing on a BT800

that's concerning (about the metric threads)..... since I really like running my threads with the motor in reverse and the tooling mounted upside-down..... guess i won't be doing too many metric threads.... hopefully.... Ok. So do the same thing except wind the tool post away from you and put the m...

Re: Shoptask 1720

I bet it would be possible to replace the crank handle with dividing head plates and crank.

Then you would have a 3-in-1 mounted to your 3-in-1. ;-)

Re: Thread Gearing on a BT800

I set it on 1 just to see and it worked, so now I know. Should I assume it's a 1 anytime is not listed in the chart? 20161101_204127.jpg Ok, if I recall correctly, you can engage the half nut on any number if the thread pitch is a) inch and b) divisible by 3 (eg: 6tpi, 9tpi, 18tpi, 24tpi, 27tpi, et...
