[X-RAY]

built a cam lock carraige lock for my lathe yesterday. today worked on a carraige stop and made a way protector. everyone asked me what i was gonna make when i first got my lathe. truth is, i didnt really know then. but now i seem to have an ever increasing list of things i want to make for my lathe. sure am learning alot.

Every time I get a new( to me) machine, the question I get from the average joe that knows nothing about machines, asks me, "What are you gonna make with it?" This question stumped me at first, but now I just say "whatever the hell I want!" ) With the right complement of machines, that statement is pretty darn close to the truth. :victory:

Being a hobby-guy, my shop projects are what I feel like working on, and this weekend I felt like wrapping up the tandem mountain bike I'm making to take my daughters out exploring with me. Fillet-brazed steel tubing that I'll probably rattle-can because the kids will outgrow it faster than a proper powder job is worth. I didn't even bother to file the fillets on this one.

I'm also working on a carriage-stop, but I'll save photos for when it's closer to being finished.

Sweet looking frame for the daughters, lucky girls! Any closeups of the unfilled fillets you care to share? I have a couple of Curtlo frames, he claims he never files the fillets, they are decent enough for me. Whats the tubing, 26" wheels, fixture method, hand shaped the miters or milled? Yeah, lots of questions, obviously answer only if you feel like it.

Also looking forward to seeing your carriage stop. I remember you got a nice new PM mill, how do you like it?
thanks, Brian

Some second hand MDF, a scrap of aluminum, two scraps of wood… and two bent nails as hinges: here is my unpatented spade bit holder.







BTW, I don't understand why spade bits must have such a long stem: I'm thinking to buy a cheap set and cut them to a more reasonable size. To have to move the drill table just to bore the seat for a washer is pretty annoying.

Years ago at a company where I worked the model shop had an exceptionally large vise. One designer asked what the model makers clamped in it. The foreman asked him to give him his watch.

Finished test fitting gears on the shaft for the Colchester Triumph headstock and then went on to get the remaining shards of metal from years of gear grating out of the gearbox. Most geared headstock lathes have a notice on them that reads "do not change the gears while the spindle is turning" (or something similar) but, some people still chance it while the spindle is slowing down or turning slowly.


The double gear with the oil hole is the only free-runner on this shaft, the rest are snug-bugs.


The shards of a thousand years (ok maybe about 50 years) on what was white paper-towel. I had no desire to blow my nose.


Some places I could only get to with an ear bud. A portion of the sump sits below the level of the drain plug so you can't just flush everything clean.


Some places were best cleaned with a magnet.

Tomorrow starts the grand assembly. )

Speaking of which ... be sure to leave a strong magnet or two in the sump! Somewhere on the bottom is probably best. They're great for holding on to any shards you might have missed and/or new ones that get generated by any rough edges rubbing.

Another good place is on the drain plug (especially if you can use brass for the plug). That way, you don't have to completely open the sump and go "fishing" for the magnet(s).

Thanks for that John! What a good idea. One never stops learning in this game.
The existing drain plug is steel. On this machine the top cover on the headstock is like a lid that is just held down by 6 hex-head screws.
What I think I'll do is place a couple of old hard drive neodymiums on the floor of the sump where most of the shards were gathered.

Got the shaft in through all the gears.
Lining the last gear up (leftmost) with it's key was a minor glitch. After hitting the shaft through the first 3 gears with a mallet, the 1st key on the shaft was not in line with its internal mating slot on the last gear. So, what I did was jam two of the gears with a gear from the drive shaft (not yet in the gearbox) and tap the last gear on its teeth in a rotary motion to obtain the alignment.
After that a mallet would no longer move the shaft through the gears so I resorted to a number of firm (not hard) knocks with a copper hammer until I saw the cellock holes on the one gear and the shaft come to full moon.
I then knocked the new cellock pin in and adjusted the axial position of the shaft with the provided threads on the shaft-ends two bushes.
Tomorrow's another day.


Shaft just coming through 3 of the gears by knocking with a mallet from the right (chuck) side of the headstock.


All gears on the shaft and in position. Just tap in that cellock pin. )

camera mount




Hey all,

Made a thing to use this camera mount from a broken tripod, on a indicator stand.
