Lathe Dog | |
I found some rectangular steel stock in the junk bin. No idea what kind but it machines nicely. It's about 1" x 1/2". I cut a length of about seven inches and trued up the whole bar before I split it in twain on the band saw. Unfortunately I got a bit over enthusiastic, as usual, and forgot to take very many picutres. Moving on. |
|
At this point I already drilled my holes in the bars (the part I forgot to photograph) but there is no big trick. I did clamp both in the vise at the same time so I could be sure the holes matched up exactly. Doesn't make much sense without pictures does it? My fault. |
|
Right now I'm squaring up my work with the dial indicator. Gotta be sure those slots are parallel and perpendicular. This took quite a bit of fussing. Initially I set up by clamping directly to the table. I was soon obvious that I'd be out of the operating envelope...no more vertical travel in the table. So, I scrounged an ill fitting vise. As you can see I used a couple hold downs on this side and had to get tricky on the back. Next slide please! |
|
Since the vise didn't line up with the T slots this is how I clamped the back side of the vise. Tricky eh? |
|
Well, it was pretty anti-climactic for me too. One pass, full depth. You can sort of see the drilled holes here too. |
|
This was a bit more exciting. The horizontal mill is pretty cool but I don't expect I'll have one of these at home any time soon. Sure made cutting that 90 degree groove easy though. This was about three passes and voila. |
|
Okay, now it's time to make...the tail of the dog? Just a piece of steel hex. To the lathe my good man! |
|
Kind of a waste of good hex, but the turning tool I ground worked really well on the steel. I'll flip this and thread the other end. |
|
Ding! Just like a microwave right? All threaded and purdy. |
|
Well, that's it! I've been criticized for my choise of bolts so I'll see if I can find some stainless ones and quell the uprising. Hey, you ask, what is that extra hole for? Balance I say! Less vibration when that thing is whipping around in circles. Okay, if you must know I broke off a tap in the first hole. I couldn't get it out and since the two sections are a matched pair I'd have to start over from scratch. So...I just band sawed off the end with the stuck tap and drilled another hole. Balance I say! |
