In order to get in there I will have to remove the DRO bracket and that wood shelf a previous owner fitted to the rear of it. I pray it's "fixable" and parts are available. I think it's going to be a problem with the gear changing forks or something near them.
If you need any help with the repair, just give me a shout. I am home for a week or two!

Errrr..... I have to give the hole drilling credit to Ken, I was away on business and he couldn't control the urge to drill!
True, dat. I was overly anxious to put the drills I'd bought to use, and with the material and prints was sitting there I could no longer control my urges. ;)
Cut like butter!

Thanks Neil, but I'm back to work except for the weekend. On Saturday I've got a luncheon with two friends. My Irish mate Mick L. had called the other day to see if I'd join him for lunch with a mutual motorcycling friend, Bob H. Mick revealed that Bob, who is about 62, has been diagnosed with inoperable cancer and has been given 6 months or so. Sad, as he's never been a smoker as far as I know.
I used a small cutting board to make a collet rack. I might have to keep an eye out for cutting board sales. Great stuff to work with and makes great collet racks. I used a spade bit to cut the holes, no grabbing at all, chamfering the holes went pretty slick as well.
The handle that I cut off was used to raise one side of the rack.

Nice job Shawn.
I thought most cutting boards were made of polyethylene, so I'm surprised you had such success in machining them.
Tom
I bought the cheapest cutting board I could find which was most likely HDPE. I drilled it with a fairly slow spindle speed and high feed rate. I got curly chips wrapped around the bit but the hole was clean and no melting. Same when I ran a two flute endmill over the cut parts to square them up. Turning this stuff on a lathe might be a pain but for this application the material was easy enough to work with for sure. I plan to make a few more to hold my 5C collets. I just need to find a few larger cutting boards.
Edit: I did try to cut the holes initially with a 7/8th spiral drill bit after making a pilot hole but that just wasn't going to work, the 7/8th spade bit worked slick though. The holes were chamfered with a cheap de-burring bit like this one.

Good idea Shawn. I got this one from Maritool where I bought my ER40 collets from. It's just a piece of 2 x 10 pine with blind holes drilled in it. I like yours better.

Started working on my version of Tom's Carriage stop, not to change his but to work with what I already had.
Which was this hunk of cast iron that I had already made into a clamp for the 12" Lathe.
I had originally started to make this into an adajustable stop from the lay out lines that I had on it but never finished it for some reason but now it looks like this, I still have a couple operations left to finish things like the dowel pin and breaking all the corners which I don't have a Chamfer Cutter for so will probably round over all the top edges not sure yet.
Looking good David. The radii are just for looks so there's no reason why you couldn't just round them on the belt sander.
That's a nice looking knurl on the thimble.
Tom
David, is there any locking mechanism for that nicely done thimble?
