Tilting table.

Hello all,

I have just finished the top plate of a tilting table. It is built from my own design and the entire construction is in MEEHANITE the table plate was 30 mm in thickness but since being faced and scraped it is now at 29.22 the size is 300x 220 .Would I be best to mill T slots or, a matrix of threaded holes either M8 or M10 on 50mm centers I was thinking that maybe the holes would be more versatile. any suggestions.

Regards,

Raymond.

Ps, not that it's relevant to the T slot / Hole question ,but the table will be approx 40 kg when complete.

Raymond,

Sounds good ! ... Do you have some pictures?

Without seeing the "tilt" details, it's difficult to say what's best; but I would probably go for a compromise.

A matrix of M8 tapped holes [maybe HeliCoiled, for durability] and a few small-section TeeSlots to take M6 fixings. Alternatively, just use the matrix, and make slotted adapter plate[s].

Michael, When I have time tomorrow I will put some photo's into my album I will also try and put in a drawing or 2 of the design

Regards,

Raymond.

I have just created a pdf of the table model, but I have now found out I can only upload jpeg.

I will try some photo's tomorrow.

Thanks Raymond

Frustrating isn't it

I have just sent you a PM

Raymond - a quick and dirty workaround:

Display the pdf and press <ctrl> + <Prt Scrn> this copys the screen onto the clipboard.

Go into paint or some similar programme and choose 'paste as new image' from the file menu.

Crop out the bit you want.

Save as a jpeg.

Tapping a grid of holes is tedious. Much easier to bolt on one of the breadboard systems used in optics lab s which come complete with a suitable grid. I've used the Thor Labs ones **LINK** with every satisfaction. £100 to £150 range for you I guess. I figured the cost was worth it compared to tapping all those holes. The anodised ally surface is very tough.

I'd put Tee slots in the table itself after considerable thought as to best size and spacing given what you intend to bolt on.

Raymond, I worked for many years on a jig borer and used a rotary tilting table with a 10in platen extensively, for my money I would put in 4 T slots.

Cast is not the best material useing threads for clamping. If you want this facility it is best to use a slave plate made from say BMS mounted on the platen with counter bored screw sockets and a series of holes as requiered. Much stonger ! Still have the plate I used and it was ground flat to close limits but you could of course scrape it same as your table platen to the accuracy you require.

Looking forward to seeing your photo's

Regards John

Thanks guy's I think I am getting to grips with this photo/jpeg lark. So I will have a go later today as I have a Holiday.

Clive,

Very good suggestion re, the breadboard .I have just been on the website and they have 1 near to my size, theirs is slightly wider but I can live with that as long as it's bigger not smaller.

JohnF,

The only reason I scraped the plate was for a bit of practice [ Right off the milling machine would have been good enough for me ] I found the scraping very easy but ,as you would expect very time consuming. but im happy with the result.

Neil,

Thanks for the info about the jpeg [me and computers are not the easiest of bedfellows]

although I can use my Siemens Solidedge fine, it was the reason I first got the computer!!

Regards.

Hi,

Just a simple tip. If you use the + combination it copies the open window only and not the whole screen. Gives you a bit more control and better resolution. Useful for instructional purposes.

E.G.

There is a free utility program called Gadwin printscreen that avoids having to use a graphics editor program. Unfortunately it does nopt work with windows 7 64 bit.

Les.

Thanks Terryd, Les, I have now managed to put up some photo's. The Solidedge has a facility for also capturing the solid model in various image formats.

Raymond.

Hi there, all,

I've just tried the screen capture procedure and to capture just the open folder it's <alt> + <PrtSc>, NOT <ctrl>. That's using Win XP.

My wife has also tried it using Win 7 and <alt> + <PrtSc> is right there too.

Best regards,

Swarf, Mostly!

Yes alt-prtscrn does it ctrl-prtscrn is the same as prtscrnm on its own.

Try shift-alt-prtscrn for some interesting effects...

Neil

Raymond, sorry mis-read your original post and assumed a rotary tilting table -- don't know where that came from !!!

Still I would use T slots rather than tapped holes. Looks good !

Regards John

Les J1,

Gadwin Printscreen works for me, on the same set-up as yours..

Hi Grizzly bear,
Thanks for your comment. I have now re installed printscreen on my windows 7 64 bit system and it now works OK. It is the same version (4.7) as I tried last time. ( I know as I intalled it on my XP system at the same time as I first tried it on the Win 7 system.

Thenks again. Les.
