Models for grinding HSS Lathe Tools

Wow! That thing is seriously built!

Yep, that is one heck of a grinder. Is the angle of the work table adjustable?

Yes it is but I'll have to find a better way to check the angles other than what is on there.
Has knob for adjustment but the table when adjusted will move if you even look at it cross eyed
I scrounged an AO 100 grit belt and tried my hand at some of the angles you all have been talking about but will have to find a tool of some sort to check them with while grinding. Good thing I have plenty of 3/8" rod to waste!!
Also have a 40 grit as well, AO

By the looks of the platen it really shouldn't miss a little chunk out of one side.

I cannot tell on yours, but on mine the table was only fixed at one end with a threaded hole and that wasn't enough.
That hole stripped quickly, so I drilled a hole aligned thru both sides to use a longer (6"?) piece of all-thread and some washers and nuts.
I have meant to make a new table with supports to both sides, but haven;t done that step yet.

It looks like your sander already has a couple holes you could use for a better table mount:

Agreed! It's heavier than the one I hacked up:

Those are the threaded holes for the back side belt guard.
But I suppose they could be incorporated into a tool rest as well with a little thought.
Thanks for the idea!!
I was thinking along the lines of making a riser for the existing table to raise it for 90*work.
After I made that last post I discovered that when the rest is tilted for grinding say, the 15* angles, the side nearest the belt raises enough so the tool/belt presses against the platen.

It also does not have a miter slide although the table has a 5/8" slot for one, to narrow for the 3/4"slide from my Craftsman table saw. So making one of those, soon as my mill is up and running (hopefully tomorrow) is at the top of my to-do list. I have another that I can modify for that use but it will have to be narrowed on each side to fit the slot as well.

Can one of you folks suggest a decent tool for checking the angles on these bits while grinding them?
Was thinking of a square head protractor but many of the reviews on Amazon are not the best.

You may have to grind the part of the table adjacent to the belt to achieve the angles you need, at least for now. Your table looks like cast aluminum and you'll find that it will catch and drag on steel tools. Maybe consider making a table from steel that is adjustable for angles but also for distance from the table to the belt.

The best tool for checking table angles is a digital protractor, at least in my opinion. I use the one from Beall Tools but any of the import ones will work.

I use a Starrett C-493B. You can find them on ebay and Amazon. I recommend these for beginners but later on, you will not need it. You can easily duplicate an 80 degree angle by eye.

For table angles, you can use the electronic ones. I use this one but there are many others.

I keep it simple and inexpensive with these from HD

For the table angles and this for finding the angles on the tool.
