I have a filing machine also. Over here they sell cheap, because no-one wants them. I payed 60 euro for mine (a little rusty and in need of new belts, otherwise fine). If these are to big for you,...

Hi Bob,
I have been on holiday for a while, but have just read your thorough but understandable (to me) explanation. Thank you very much for the effort to write this all down!

Peter

Hello Jan,
I would also be interested in a copy if you don't mind. Thanks!

If this is what you need, wouldn't a mt-enlarging sleeve be the way to go? I have a mt2 to mt3 sleeve for example. Can be bought easily over here. Sort of reverse reduction sleeve.

I read all this information with great interest, and you seem to know a lot about it. You are undoubtedly right about more thin layers instead of one thick, but I can't understand what happens when...

Nicely made attachments! Concerning the slider: this is something a lot of woodworkers have made for their tablesaw too. Since a spinning sawblade protruding through the side of the jig you are...

Hi Bob,
Thanks for the explanation. Sounds like something I will try in the future. I have a couple of questions if you don't mind:
Why heating in oil for so long? Isn't it enough if the formed...

I am quite late to read this thread and am reluctant to reply, but when I saw your sketch it reminded me of the working of the clutch/brake of my shaper. I have no experience designing these things,...

Hello dsel74,
Here are some pictures of my AI Hembrug shaper with its original vice. Not a big production shaper, but rather a toolroom shaper. The vice is proportioned accordingly (base 160 x 160...

Hello Ian,
I am following your thread with interest, but since I have no Hercus grinder (I live on the wrong continent for that) I had nothing to contribute.

Michael,
Thanks for the pictures, that helps a lot. I understand what you mean concerning the helix angle, and yours likely is the more practical solution.
The solution I cunjured up was to put the...

PDW, I understand what you mean. Attaching the gear quadrant to the x-feed should be possible although not straightforward. It would help to see an example though. Any chance you can scan the part of...

Bollie7 thanks for your replie. As mentioned in an earlier post, as far as I understand things I think you are right.
Peter

Jan, thanks for the replie. Could you explain how that is done?
Peter

Michael, thanks for your input. I didn't think of differential indexing, thanks for the idea! I googled it and have some idea now how it works. Now I need to check out if I can figure out how this...

Aaron and pipeclay, thanks for your replies. As far as I understand things I tend to agree with Michael, there is just the cutterspeed related to the feed and the feed related to the rotation of the...

I sort of understand how it works now. And I can understand why the quality of the mirror is such a big thing.
If the manual becomes available I will take a look...

I follow this thread with great interest, always eager to learn something new. I was hoping to learn what this apparatus does and how it is used. Does anyone want to enlighten me?
Thanks!

Re thread micrometers and use of indicator:

Just another thought:
You could try and match the taper on the chuck to the taper in the spindle most are not really hardened. Transfer the contact areas by marking the taper with sharpie, chuck in...

I have read this thread with interest. Two questions came up. I understand the use of thread wires and gauges, but aren't thread micrometers possible too?

Bob,
What are the materials it is made off?
(my guess: aluminum with brass bushing, hardened steel punch and ?acrylic? lens?)

I finally succeeded in uploading the picture. Haven't been able to log in to the site with tapatalk for some days too[emoji19]

What do you people think, twins or what?

Peter

I have tried to upload a picture of my grinder, but for some reason it doesn't work. I will try again later.

Hello Burner,
Could you post some pictures of the attachments you have for the cincinatti?

How would you put fine parallel grooves on the back of a tool steel insert. Now if you could work that one out, you could also make your own thread chasers.

Thanks for the picture Stuart. Although nicely made, not too complicated. I should be able to use this design.

Hi Stuart and Bob,
Thanks for the interesting info. That feature might even be added to my current stops I think (a small version that is). Is the plunger with reference mark only prevented from...

Hi Bob,

I can only agree with your remark on window shopping. I like to do that a lot myself, at least regarding "old iron" :cool:

Hi everyone, thanks for your kind replies.

I picked up the radius grinding attachment for my U2 grinder yesterday:

It seems to be in good shape and only needs minimal clean-up....

Fred,
It's done. How come you remember the city name anyway? Dutch roots?
Peter

Fred,
Confusion all around :eek::)
And yes, you are right, I must have made an error when I made my profile.
I will correct it, thanks.
Peter

Bob,
By the way, have you posted any pictures from your grinder and accessories? I am curious about how yours looks.

Peter

Bob,
You are certainly right about the accessories of grinders.
That's why I am constantly on the lookout for them. I am still looking for the relief grinding fixture and have a lead for the "long...

Bob,
That's right. The turning piece is made in one piece, so the collar moves from the reference-line if you screw it out. I personally think this part could be improved. Either another way to fix...

Fred,
It has always been "Alphen aan den Rijn", but "den" is the old dutch word for "de" which means "the" so there is not much difference.
literally translated it means "Alphen at the Rhine", and...

Hi everyone, when replying to another topic, I was asked to show some pictures of my AI Hembrug universal grinder.

Truth be told, I have more than one. This is the one I want to keep for myself:...

Bob,
I found the micrometer stop.
341284
It's the bottom one. The top one is another incarnation of the normal stop.
I have taken it apart:
341285
341286
341287
341288

Bob, you are right about the function of the big setscrew. The small one rides in the groove and limits the travel of the plunger. I will search for the micrometer stop and post pictures.
I will...

Hi Bob,
As it happens I have a AI Hembrug universal grinder and it's documentation.
The standard stops are spring-cushioned but have a threaded (m8x1mm) bolt to "fine tune" the setting. There is...

Bello John,
I don't have any extra chartclips, I have only one myself. They should not be that hard to make though. I could measure and make a quick drawing for you if you like.

Soundman,
I have no plasma cutter yet, but am redesigning my compressed air system and would like it to accept one.
Would you mind describing how a system with secondary tank would typically look?...
