    It's doable on a fine thread. I wouldn't try it on 4 TPI. Set up correctly with a solid bite on the hex you could probably do it without pulling it out of the chuck but would be pretty likely to get...

    You won't bend that thing taking any depth of cut the cutter could handle - at least as long as you have it spinning. The clamp studs would be way more likely to shear first. And you sure as hell...

    If you've got some, post 'em up. There are quite a few guys who could use some more judging by the fellows getting in line when some are listed for sale.

    Go right ahead Jacques, and thanks very much for the offer also Buck!

    I like the Last Word style, though that Clearview does look nice too. A Newbould would be awesome but they are out of my reach cost-wise. Shame, as I really liked RJ and it would be pretty cool to...

    Yep, was thinking I'd do just that before I ended up tearing the machine apart. I'll definitely get something made up after it's back together. Hopefully that should be in the next few days, just...

    Add another to the list. I made a small 5C collet chuck almost 15 years ago from 4140 Q&T (same as pre-hard). It was used pretty frequently though not every day and the only indication of wear is a...

    This is what the front of the table looks like. The funny thing is, I have just been going through all the manuals I've got looking for any mention of clamping or stops on the table longitudinal...

    The trouble is, I don't think the machine has any kind of stop on longitudinal travel. Bob you have used these a lot, what's the word on that?

    Buck, after thinking about it I now actually wonder that I can even use that vertical style dresser without a table lock. Near as I can tell the machine doesn't have one unless I'm just totally...

    I always wondered why the wheel guard on my grinder was mounted on a plain round diameter so it could be rotated - that is probably exactly why.

    Anybody know of a video that shows the J&S in...

    I think the only real difference is the capacity. 675 is 7.5" and 688 is 8.8" AFAIK. That one sure looks like a 675 to me. They probably have their records narfed - send them a pic of the S/N tag.

    The only trouble, Tyrone my friend, is that it's difficult to meet some of the asshats that troll - or are just complete jerks - in the carpark on here. Trust me, there are a few that I'd have...
  14. What are some of the nicer radius/angle dressers?

    Looking to acquire a radius/angle dresser for my grinder, not real familiar with what is out there so I figured I'd run the question by some of the old grinding hands here. What are some of the...

    Yes there is a return path outside the relief circuit...According to the circuit diagram your line 'b' is connected to the outlet side of the relief valve... It doesn't pass through the relief valve....

    Had a minute to look a little closer and yep, looks like your grinder does connect the cylinder lines together when the throttle valve is in neutral or off position. So there's your bypass back to...

    Doesn't the heat from soldering distort the part? I would think this method would not be all that great for maintaining flatness unless the grind was only for cosmetic purposes.

    Nope. Bypass valve is not a relief valve. Totally different item. You don't seem to understand how the system works I think. You keep saying "when there is oil flowing from the pump" and "when there...

    You might also want to update with your hydraulic cylinder seal info too, since you just got into that also. Just in case any future searcher turns up this thread but not the other.

    The bypass is not internal to the pump, it will be somewhere in the output piping. It is just a return line going back to the sump with a valve that's closed when the table throttle is in operating...

    Yeah, compression fitting. I'm surprised they haven't heard of it... Pretty common here in low to medium pressure hydraulics and air lines.

    The pressure thing is normal, when the hydraulic...

    Yeah me neither...I was totally imagining what Jamie would be saying... He seems like he would fit in here pretty well.

    I was taught to dress with coolant if you'll be grinding with coolant. Dress dry if you'll be grinding dry.

    Eek. Thought he'd understand C of G better than this too. That thing is an accident waiting to happen.
