Hi Rob ,

it looks  too good to hide under a coat of  paint     :ddb:

what speed did you face the underside of the plate with it being unbalanced ?

I'm fairly sure you were making some scrap metal so the rest of us would feel a little less inferior?  :lol:

Seriously - blummin good work as usual Rob, that keats thingy looks fabulous.

Rob rather than that mill contraption can't you just bolt your new Keats plate to the mill table to do the same job?

Hi Rob, :wave:
What happened to the CNC mill, just kidding it has been an interesting read. :beer:
 :proj: :mmr: :headbang: :headbang:
You do a great job of taking photos all the way through. I do some photos and know how easy it is to forget and how much extra time it takes , so thanks as it makes it a good read.

I also do the weld and machine type of of jobs because getting casting done over here is near impossible.

Keep up the great threads

The Keats would be OK for shorter lengths ,,,, as i said Longer lengths of stock/jobs   For example this operation on the clamp bar .

The Keats would be no good whats so ever .

Yes i could faff about and packing it  up ,, also the Keats has a large foot print so it could not be used so well on the surface grinder .
As i have at a rough guess a Ton ++ of steel  :)  i may as well use a bit up and build one  :dremel:

Thanks Dave   


Pleased you liked the photos  :thumbup: you should take your camera in the shop more often  :poke:   Have you ever thought about setting up  your own foundry ? ,,,, I probably would have cast these if i had got my butt in gear and sorted the furnace  :Doh:  :proj:


Cheers Lads Rob


Edit :   Thinking allowed again  :palm:  ,,, maybe a smaller version that would fit the mill vice may come in handy .

Warning: this topic has not been posted in for at least 120 days.
Unless you're sure you want to reply, please consider starting a new topic.
   :Doh: its been that long  :lol:


Picked  up a couple of 8mm pitch/20mm timing pulley's tother day for the Z axis .


Part machined up the mounting block for the Y axis nut to see how much room i had left to fit the Z lead screw pulley .


mmmmmmm there is no room to fit the pulley  :lol: :lol: :lol: :lol:


I can turn the nut 90 deg that would give me another 7 mm to play with . Wont look as nice  :(

I was never impressed with the section of casting that houses the Z axis bearings , and there was not allot i could do with it as it is to fit the new bearings ect ,,,,,,,,,,,,,,,,, so  i removed the offending lump  :)

No going back  :lol: :lol: :lol: :lol:

Hi Rob,
Your doing some fantastic work as usual.
I know your probably well aware of this, but I just thought I would mention that cast iron gusset helps hold the Y axis ways apart, so when tightening the gib it wont squash the ways in.

I will keep watching to see what your doing, but as with all your projects I am sure you have it all worked out and under control.

I was thinking about you the other week when I was chasing up one of your posts for someone, and got thinking I have not seen much of your work lately, then I remembered you did your back, how is that going? I have a broken C3 disc, and I know how these things can lay you up.

Keep up the great work and posts. Always interesting to read and the clear pictures are a bonus.

Dave

Cheers Dave ,,, my back is much better now thanks  :beer: ,,,,,,,,,,,,,, Good to see your paying attention  :med: ,,,,,,,,,,,,, I had measured the casting at a few reference points before and after i had copped that portion of the casting , so i could check for any movement in the casting , there was none  :thumbup: ,, i will be replacing the part i chopped out  :dremel:.

Even if you look like you might be making even more work for yourself on it  :Doh: :lol: :lol: :lol: :lol:

Evening Lads


The two lugs that i had left on the casting will be used to mount the new Z axis bearing support   :dremel:


Using my HZ arbour vertically allowed me to reach into the casting to machine the lugs . :dremel:





Now i have something to work from  :med:

I think this says it all:

 :jaw: :loco: :bugeye: :bow: :bow: :bow:

Really nice work Rob, those lugs cleaned up a treat, and what a stonking setup.


Note to self: Once finances recover, buy horizontal arbour to use as spindle extension....
Cheers!

Thanks  Ade ,,,,,,,,,HZ arbours do save the day sometimes  :dremel: :D


Spun the nut 90 deg and machined of the excess from the nut mount .
 

Plenty of room for the pulley and the nut to pass  :ddb: :ddb: :ddb:.


I will have to make a new nut mounting block as it looks naff as is  :coffee:
