Re: Bolton at-520 cross slide nut

If you change to a metric thread, you will have to change all your change gears too. A different pitch would result in wildly inaccurate threads!

My lead screw (and I suspect many others from China) is a strange hybrid -- it's actually a metric diameter with an 8tpi pitch.

Re: 4 jaw chuck on a HF 44142

The other areas often are of interest to 3-in-1 owners. After all, if you own a 3-in-1, you own a lathe and you own a mill. So those areas may be useful too.

Granted, as a 40 year retired machinist, you may spend more time answering questions than asking them. ;-)

Re: 4 jaw chuck on a HF 44142

Do you mean the 3-in-1 section? Yeah, it's been pretty quiet of late. Other areas seem to have regular traffic though. Speaking personally, I often find my questions are already answered with a quick search. So I do more lurking than posting now. I jump in if I see a question that I can answer. But ...

Re: Way Wipers for 3 in 1!

I might have -- I don't remember anymore. It's also possible that the holes were pre-existing.

Re: oil for headstock

I use Amsoil "Super Shift" synthetic transmission fluid.

I figure it's for gears in high-torque applications. And temperature stable for those mid-winter days in a cold shop. ;-)

Re: Way Wipers for 3 in 1!

I did. https://picturehosting.verhey.org/hq800v/felt_bed_wiper.jpg After much research, I used F1 industrial felt. I believe it was 3/16" thick. The dovetail is 60°, and I used a nice sharp utility knife to cut it after pinching the felt between two parallels as a guide. Secured to the carriage with...

Re: Grizzly G9729 Mods

I also added a DRO (Sinpo 3-axis) and felt wipers for the carriage. But I can't seem to find those threads now.

Re: Grizzly G9729 Mods

Your machine is very similar to mine (HQ800V), so some of these mods may be applicable: https://www.chaski.org/homemachinist/viewtopic.php?f=27&t=87470 https://www.chaski.org/homemachinist/viewtopic.php?f=27&t=88872 https://www.chaski.org/homemachinist/viewtopic.php?f=27&t=96110 https://www.chaski.o...

Re: Grizzly G9729 Oil Leak

On my machine (similar design), that round thing (under the chuck) is a site glass. The oil level should be no higher than the top of it. Is your oil level too high, maybe?

That's the one thing that tempts me to trade in my flip phone -- I understand there are apps available for smart phones to filter out the spam calls.

Good luck finding a flip phone any more. They are becoming an endangered species.

Re: 3-in-1 Advice Needed from the Experts

Most 3in1 machines have 2 motors. One for the lathe and one for the mill. (A very few run the mill from the lathe motor via a gearbox) That Shopmaster looks like it's missing the lathe motor as well as having been dropped. Lord knows what other hidden damage it suffered. I would absolutely pass on t...
