    Werowance attempts Upshur Vertical Single

    I do it the same way--start the die on the tapered side, and if I'm threading up to a shoulder then I turn the die around and use the untapered side to get in tight to the shoulder. If the treaded part is screwing into something that the shoulder must bear against, then I will go in with a 1/16"...

    Moving my lathe

    A number of years ago, someone (I don't remember who) gave me a bunch of huge old bearings, because they knew I "Built things". I never throw anything away, so when it was time to devise a wheeled carriage to move the heavy end of the lathe, I used a piece of 1" thick aluminum bar and a couple...

    Moving my lathe

    With the lathe correctly positioned, it was a simple matter to lower the lathe into it's home position and bolt it into it's final position on top of the cabinets. The lumber and the wheeled carriage are bundled together and put into storage in case I ever need to do this again. (God forbid.)

    Moving my lathe

    Now, as I said in my previous post, "In theory I can push the wheeled carriage with the heavy end of the lathe suspended from it into place". In reality, it didn't happen quite that way. The heavy end of the lathe was so heavy that the 3" o.d. diameter bearings on my overhead "wheeled carriage"...

    Moving my lathe

    And here we are with the lathe in my machine shop, almost in it's home position on top of the cabinets on the right hand side. You will see that I have built an overhead gantry, with a wheeled carrier riding on top of the dual 2 x 4'rs passing over top of the lathe, supported on both ends by...

    Moving my lathe

    From my garage, one has to pass thru my office to get to my machine shop. (My "machine shop" used to be an annex of my office, with a huge old drafting table in it). The "wheeled transfer table" is quite easy to steer, with fixed pneumatic wheels and tires under one end , and swivel casters...

    Moving my lathe

    A week ago, my lathe quit. This was very upsetting, because it had just quit about 2 or 3 months ago, and had to be taken to Toronto for repairs. Fortunately, the safety switch inside the change gear cover had slipped out of adjustment, so my cost was negligible, but the hardest part was getting...

    Building the Trevithick engine

    I will start a new thread on moving my lathe. There is nothing real earth shattering about what I have designed and built, but it is new and a bit different. I am very conscious about the possibility of hurting myself when moving machinery, so people may find it interesting.---Brian

    Building the Trevithick engine

    Loren--I got a call this morning. Trouble was caused by a loose connection at the reverse switch. Lathe will be home on Wednesday. I have designed something to help me put the lathe back in it's place, but will start a new thread for that.---Brian

    Building the Trevithick engine

    Ray--I don't know. I pour my heart and soul into building these machines, and by the end of the build I am burned out. Right now my lathe is broken, and back at the suppliers in Toronto for repairs. My next build will be when the lathe comes home, and it will be something to aid a 74 year old...

    Regardless of what the picture looked like--I try to remove the chamfer completely so the gripping edges are almost as sharp as knife blades. This is a very slippery slope, because if you get too enthusiastic and grind beyond the "cutting edge", then you have a gap which won't grip anything.

    Yet Another Webster Begins

    Take a pair of wire cutters. Look close and you will see that there is quite a pronounced chamfer on the side of the jaws. Hold the cutters up against a grinder until that chamfer is almost gone, leaving a sharp edge. Now the wire cutters will grip the pin and pull it out. It is also a great...

    In-line check valve plans

    Best trick in the world for that. Machine the ball seat to be a sharp corner with no chamfer or radius on it. Put the piece in a vice and drop a sacrificial ball down into it (Same size as finished ball) , put a long nosed punch down the hole against the top of the ball and give it a good whack...

    Building the Trevithick engine

    Thanks guys.--A word of warning---I would not use that brand of paint again. As soon as it dried it started flaking off. I have never had that problem using Tremclad or Rustoleum paints, but the colors are somewhat limited. This paint is "Dupli-Color Perfect Match" sold in aerosol spray cans by...

    Building the Trevithick engine

    So, the Trevithick is completely finished. The painting was finished 3 days ago, and it was all reassembled this morning and posed for some "beauty shots". I had a few issues with this build which involved the cylinder and the 4 way valve, but in the end I used a more conventional slide valve...

    Building the Trevithick engine

    A stinky business!!!--Wish I could have done this painting a month ago when it was warmer outside. As things set, I open my big garage door, set out all the stuff to be spray painted, paint it, then move everything into my machine shop so it will dry enough for a second coat. This comes out to...

    Yet Another Webster Begins

    You have the carb positioned correctly. You most smear a bit of green Loctite around the o.d. of the discharge side of the carburetor. It is 10 mm in diameter and fits into a reamed 10 mm hole. The Webster intake manifold as per drawing will not fit that carburetor. You need to make a male to...

    Coulsea is right. Top of gas tank marginally below center of carburetor or it will constantly flood itself.--Gas runs down-hill from gravity. Forget the wd40 added to your fuel. Use a bit of 2 cycle oil added to it.
