Rotary table expansion
Rotary table expansion
Previously I posted a question on setting up a RT and now here is how I fixed the problem: The RT I have is 6", so I took a piece of aluminum plate, 12" diameter and bolted it to the RT on spacers so it sits 3/4" above the RT top. I then milled 4 slots, 90° apart to accomodate tee nuts. I bolted it down using hex head bolts. I then took a skim coat over the bolt heads for a flat plane. The aluminum I used was a 7000 series aircraft alloy. I won't be doing much work on steel; mostly aluminum. 3/8" would have been sufficient for spacers, but I had 3/4" stock on hand. If I come across some 3/8" stock, I may switch them out.

VERY NICE JOB INDEED
EDIT: I think I will have to make one
like yours, but with one spacer ring all the way
around which should give alittle more support.

Re: Rotary table expansion
This kind of extension are found on the net in several places. One variant I used was a solid table with machined buttons that fit the original table T slots so removing the extension can be repeatable within limits.
I didn't use T slots in my extension but just drilled 1/4 inch holes at one inch spacing in concentric circles on the extension plate. I just use hold downs for set ups. I didn't want to use valuable vertical room on my little Clausing mill.
My extension is made from 1" 7075 Al plate.

A one piece spacer ring would restrict tee nut slots outboard of the ring.ken572 wrote:Mr Ron

You thought I was ignoring restriction comment didn't you..hah.
Nope, you brought up a good point. I think I will go to a 1" or 1.25"
thick spacer ring and cut an abundance of Tee Slots above the original
table, which will fix the outboard problem you mentioned, and also raise
me up a little more, which will be helpful for most of the jobs I will do on
my HF-44142 3in1 Mufti-Machine. It will be an Uninstall/Install Accessory
Plate anyway.
