Sounds like a plan then Bob. I can understand the finances being tight.

Ya, why didn't think of that, "prototype". Have to see if it'll work or not so why use expensive material the first time. :)

Wow Bob

That looks like a lot wood to stain, don't let Bogs see it, as it'll give him nightmares you know what he thinks of wood
£$%^&*.

:D :D :D

Nice looking house by the way.

Well I had a few hours in the shop today and got 1 pin fitted so I have a few more pics for everyone. I decided I would make a hex head and use a socket to tighten the pins.

Here is a shot of the pin inserted into the reciever and turned so that the chuck can be mounted

Here is a shot of the pin rotated 90 degrees.

Once I get all thee pins finished I will tighten my 5c chuck down and measure the run out. I am a little worried that the 90 degrees will not be enough to lock it and may have to reduce the dia of the pin where the interferance fit is.

I will keep you all posted on my progress as I get time. The logs are now ready to stain but we have 3 days of rain coming so I may get a few hours over the next 3 evenings to work on it a bit more.

sbwhart:
Progressing well Bob

Tomorrow is a holiday here in the States and the company I work for gives this off to us. Since it fell on a weekend day they gave us today off. :D

Since it is my birthday and we have a threat of rain I didn't do any staining on the cabin today....instead I made some great progress in the shop on the reciever.

I was having some trouble getting things concentric. After bluing up the register I found that when I tightened up the receiver pins the chuck would be pulled slightly off center and would not let the chuck sit tightly on the face. :bang: Ok...so back to the mill, find center again on open up the holes about .010. PERFECT!!!!.... Before doing this I noticed that my 5C collet chuck was the only chuck that would fit fairly well in the holes. The rest would not drop down low enough because of binding. What I found after checking the bores for the pins on the lathe reciever that they were made for a very sloppy fit. Now I have just slightly over .001 TIR with it mounted in the 4 jaw and when I finally fitted it to the rotary table I have the same results with a .75 dia rod held in the 5C collet chuck. I am more than pleased with this as I was shooting for no more than .003.

Here is the 5C collet chuck mounted to the reciever. It measured .001 + TIR here.

Here it is mounted on the rotary table with the same TIR.

Here are the other D1-4 chucks and face plate mounted on the reciever:

Obviously the height will be a problem for some, luckily I still have plenty of room left and now I can mount any size d1-4 chuck to the rotary table.

I still need to make the detents for the pins so that it is easier to locate where the pins are set to remove the chuck, I have been kicking around the design of the pins quit a bit with circlip via skype and I will be cutting a grove all the way around the pins. Spot drill where I want the detent, then use a metal ball and spring with a grub screw to push the ball into the detent.

Crap-O-Cad drawings to follow. :beer:
