My Little Husky

[Groomengineering]

Hi all. Well, I started a Little Husky as a winter project but I hate the cold so I guess it turned into a spring project. In the last few months I've managed a little progress,

You may notice the lack of nuts on the centre columns. As drawn there is about .005" clearance between the top stud and the cylinder. Now I know why every picture I've seen has the holes but no columns in the middle. Not to be defeated by a mere drawing, I decided to put posts on the columns and call it a feature. ;D

Managed a little shop time last night, and promptly stuffed up the top plate. Measure how many times..... : Wow, take a few months off and it seems like I forgot everything. Anyway, new top plate made and we'll give her another shot tonight.

Cheers

Jeff

Hi Jeff;
Thanks for sharing your progress. Don't worry about the top plate. We all do a "stuff up" now and then.
Keep it coming!

Hi all! A bit of an update on the build. I've been getting almost zero shop time in, it's terrible when life intrudes on your hobbies....

Bearing blocks in place.

Drilling and reaming for crankshaft.

Cam blank.

Crankshaft started.

Everything together so far.

And yes that's rust all over everything :hDe: The pine board will probably end up being the base, just haven't figured out the shape/size yet.

Cheers

It looking good Jeff. I can see where it gets it's name....stout little thing!! Is it your design or if not where did you find the plans?

Regards,
Bill

Thanks Bill!

The original plans were published in Pop Sci Jan 1944, but the drawings are available on the JohnTom site.

Cheers

Hi all! A little more progress. How to cut the cam without the RT? Let's see if this makes sense. I drew up a circle the size of the cam in CAD, put in a horizontal line and an angled line to give the 150° angle. Dimensioned and found I would need a mark on the centerline on the right and a mark .172" above centerline on the left.

Soooo..... set up using the frame for a stand

Marked the lines

Couple of cuts in the mill

A little file work, sanding, and a setscrew

And we have a cam!

Looking back I think that this was probably easier than setting up the RT would have been. Unfortunately I'm going to need the RT to finish up the cylinder, so it's 'build a 3-jaw adapter plate' time. Oh well, tool projects are fun too. ;D

Cheers!

Looking good Jeff. Didn't realize how small the cam was until that last pic next to the bic lighter.Keep up the good work

Thanks guys!

Made some good progress on the rotary table adapter yesterday. I'll put up some pics of the build if it works out. Looks like I get to spend most of today trimming trees. Yay.... oh:

Cheers

Jeff

 

[arnoldb]

Jeff, you made a nice start - can't wait to see more progress after you've spent time on the brown stuff ;D

Nice file work on the cam ! Thm:

Like Larry1 said; it sure is a _husky_ little engine!

Regards, Arnold

 

[Groomengineering]

Thanks Arnold! I think we got the trees beat, 'bout killed us but we made it. Yesterday it was 99°F, 50+% humidity, heat index of just over 110°F, forecast of pretty much the same all week..... I think it's time to do some indoor work now and the heck with the yard. :big:

Cheers

Jeff

Hi all! Well, after a myriad of other projects and a general lack of any shop time it's time to get back to work. woohoo1

First off I've finally gotten the heater installed and hooked up.

It's a 75k btu unit heater originally purchased to heat the entire 1000 sq/ft garage, but plans changed and it now sits in my 380 sq/ft shop. A bit of overkill, but it'll do 0 to 80F in about five minutes. ;D

Anyway, to resurrect the thread.... I've done some work off and on, drilled and tapped head bolt and cylinder mounting holes, made a cylinder head, and made up the poppet valve. I thought I took pictures, but I can't seem to find them. :shrug:

Todays progress, wired the valve body and cylinder together for soft soldering on my makeshift hearth (read cinder-block oh: )

Applied heat and....

Well it looks a proper dogs breakfast but it seems to be solid, and everything lines up. A little Bondo and paint should fix that. Thm:

Piston and con rod are the only remaining parts, maybe I can get this done in under a year..... ;D

Cheers

Jeff

Keep those pics coming!
