A Wallaby of my own.

Thanks Dan....that square drive gave me heart burn for a bit.....but in the end it wasn't that bad.

That's a nice gear Dave, I want to see how you make the pinion.

Thanks for the interest and support Don!

Here's the blanks for the pinions



Jo, here's some previous photo's of a build I did way back when using the filing rest to make hex head screws.....too tired tonight to stage a part for photo's  These screws are domed headed with an integral washer.  Because of that I had to flip them for making the hex.   With a standard hex head bolt, I don't even need to part off.    I cut the head first than part off.










These are 5-40.   I'll be using that size for the sump on the Wallaby.
You can see that the safe edge is stopped by the flange on the roller.

Those gears certainly look the part, and nice bolts too. I gotta set my lathe up so I can do that, already have the indexing up and running.

Anyway you should take holidays more often Dave. Look at all the stuff you can get done

Thanks Steve!   Like I said....with 6 or so and especially small screws....I think I can file the flats quick...but If I'd had to make a lot of them....Jo's method ...or some other mechanized method is far more practical....

When I have my SB in full song.....I'll show you what I mean....

I haven't been able to get that filing rest out of my mind. Guess I'll have to make one some day.

[steamer]

I'm glad that part is behind me!    Metalmad did a great job of this on the "other" place.....my hats off to him!   That's a tough bit and he made it look easy!

An excellent job Pete!

Those are mighty  big stops on your filing rest Dave. When you make little bolts do you not find having to stick the material out to provide sufficient clearance that the stock bends?

Ok I am now confused: Are you doing the heads before the threaded end?....... read it again I can see what you were doing now .

Jo

[steamer]

No worries Jo!   Yes getting the part to hold together seems troubling...but #5-40 is pretty good size...about 5BA...

My SouthBend will be different though!........THAT will be the fast way ....I think,,,,

Dave

[Jo]

5BA  that is a monster,I can see why you would have no problem with the stock bending .

Jo

[steamer]

I think I got that right.... the bolt diameter is .125"    I think 5BA is .127.......I think

[Jo]

5BA = 3.2mm or 1/8" in old money.

If you go up to the post on the filing rest, you will find a spreadsheet attached on BA comparison......  .126   .....close enough!

stud manufacture in the future.....

Hi Dave,
I have one of those for my SB heavy 10. I guess I am lucky as it is to high and I will have to learn scraping.

What type of die head do you have? I have a releasing acorn style with 5/8" dies.
