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!

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!

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.

Nice job Shawn.
I thought most cutting boards were made of polyethylene, so I'm surprised you had such success in machining them. Tom ![[Image: TomsTechLogo-Profile.png]](http://tomstechniques.com/wp-content/uploads/2013/11/TomsTechLogo-Profile.png) 
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. ![[Image: qvv7.jpg]](http://img841.imageshack.us/img841/6260/qvv7.jpg) Shawn

It's just a piece of 2 x 10 pine with blind holes drilled in it. I like yours better. Ed 
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. ![[Image: carriage-stop0.jpg]](http://s1222.photobucket.com/user/Superdave257/media/carriage-stop0.jpg.html) 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. ![[Image: carriage-stop1.jpg]](http://s1222.photobucket.com/user/Superdave257/media/carriage-stop1.jpg.html)
