Re: What is this for?

They had all kinds of attachments on the older horizontal mills. There were thin belts coming from somewhere driving grinding arbors or fixtures to hold them.

Re: QC toolpost for Atlas 618

I think it a tad large. The triangular designs are really cool.

Re: Preparing Machines for Moving

I really don't want to abuse this thread further but there was a reason. When I was really young, living in Tennessee, I was exploring everything . There was the normal type rock of the mountains and different type of different ranges. The calcium or shale type were already blown thru for highways a...

Re: Preparing Machines for Moving

It has become a rock which holds secrets. I know you don't have time for this now.

Re: Preparing Machines for Moving

While it is difficult to surmise, that rock looks like a meteorite buried underground for ages. I would take a chisel and find what it is made of. Sure I'm stupid but not all rocks are the same. Where did it come from ? it wasn't river rock . Some ancient volcano spewed it high or maybe used for fil...

Re: QC toolpost for Atlas 618

In closing, I should mention the turret which came with my 9A. It is four station also but each station has a "rocker" in the middle. Four bolts per station but the tool was adjusted more quickly ( and removed, ground) shimmed but sometimes you get lucky.

Re: QC toolpost for Atlas 618

" the final pass left the items in the desired condition" . No question, that. There are many turret designs even within our scope. I'll say something about the Enco turret which came with my "new" lathe. It was sturdy and had the incremental positions but was too high. I had to mill the base part w...

Re: Boring large holes/product review

Very well thought out and very creative. Even your machine table had to be made certain height. We can see the four bolts of the tapered "spud" which is locked tight by three tapered bolts in the cross slide. I just think it worked out fine with replaceable pilots and you were ready to go a differen...

Re: Worn pulleys/ additive metal

I have a 5' belly deck and while it is physically right heavy, it is suspended at four points. Two points raise or lower at my whim over unequal terrain, via hydraulics and linkage to keep it parallel. Sometimes it must be raised high, so there are additional idlers to keep the long belt from rubbin...

Re: Worn pulleys/ additive metal

I get all that but it doesn't apply in this case. Just one section of a double Vee pulley needs to be built up. The pto exits the back, in line with the drive line. One long single belt is configured by idler pulleys to either reach a tow behind deck or a belly deck. In most cases, it contacts the t...

Re: Worn pulleys/ additive metal

I suppose "low end" is correct. Since they are lighter, I don't see that process being used. There is more about metal transfer than I know. In an electrolysis bath the rust is usually extracted but a sacrificial electrode could slowly build thin surface. I just need more info about it.

Re: Worn pulleys/ additive metal

I have to say by looking at abom79 videos, he knows additive metal and much more. Thin pulley facing is different but good ride.
