• Husqvarna Motorcycles Made In Sweden - About 1988 and older

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

83 cr500 one worthy of some love and tlc

Did you use a tool grinder machine to square edges. A machine shop tool for setting up - cutting tools for hardened steel ? Used to cut the hob teeth with these.

how did you index the engagement dogs to match sockets or slots ??
 
I have and also new 4 speed set to sell , haven't set a price. But you don't need that now. 40% of gears are new.

Mick, o lordy, ain't you the talented one tho!!

very nice, I admire the extra steps some people go to with their/our old bikes.

Did you have any problem with shrinkage?...errrr...

A local library somehow has a 3D printer and a 3d scanner..
The scanner scans your part..well, haha...and supplies a digital (oops again) file for the 3d printer equipment to print the sample part...in plastic I suppose.

The library is encouraging people to learn to use it, soo...

I theorized about

1. scanning a part...(stop it, a motorcycle part)
2. tinkering with the scale of the digital rendering, adding where appropriate design changes are desired, and adding enough for shrinkage and extra material to machine away to the right surfaces
3. 3D printing in plastic which would serve as the plug
4. then make the core boxes and all like you did.

good show, keep it going..

bang on you done your research too
1.5% shrinkage depending on alloy and liquid pressure during process

im not making gears just restoring lost metal and shaping beveled flats so not a hard task at all on husky gears hardening comes after machining and bedore final finish so cutting tools nothing exotic just carbide
 
mick83Husky...since then I have done a bit more down the rabbit hole reading about 3d printing and the questions I had seem to be answered in that:
: metal 3d printing in now a long and well known Thing!!...and the specs for the alum alloy seem to be at least 5010% BETTER than a usual alloy used on Brit Bikes, 356 T6...so THAT is f##%%%g amazing. I operate on the long slo time period unlike actual Progress!...lol.

I certainly need to know tons more, but the possibility of 3d printing, avoiding much of the machining sounds great!..an avoiding the costs of the foundry work, the cores, core boxes and all the stuff reqd to cast a simple barrel or cases seems very promising.

There are shops adverting for you to send them a file, they send you the parts. What a great world huh?

ok, now someone go and burst my bubble with a real world quote for 3D printed aluminum parts...size for one problem, BUT the printers!! are getting cheaper and cheaper and have room for some actual MC sized parts. 3d printers are now cheaper than a clapped out Bridgeport mill with obsolete tooling.
 
Well uncertain today were the industry is, but we have powderd metal gears in transmissions 40 years ago. Working in a gear factory as QC guy they were strong
but not as strong as the metal cut gears.

I could see this same product that was made under pressure, being made by a 3d printers. I have see made in front of me on a simple 3d printer for some sample gears
made. It was fascinating !! Also I have see a complete roller bearing made from scratch - I mean complete assembled piece. It was plastic , but could see how a special
powdered metal could be used. These were samples

Hear is the crazy thing all are made from the center of piece. So it builds bit by bit from the center of the ball bearings, center of races. And a piece appears as it grows from
the tiny spray jets. They are using human cells to make some tissue replacements now in the medical field.

It coming soon for smaller parts but to see big parts made - Go to the Space X site. The rocket makers. They are making complete large rocket engine parts for their engines by 3d printing today.
 
I saw some 3D printing examples in plastic about ten years ago. I had a bit of a hard time wrapping my mind around it at first. I saw a " Simple gearbox" sealed except for a couple holes for extracting the excess powder. Crank the input shaft & with gear reduction the output shaft would turn. Also saw what looked like a ball of string but in no places did the "string" touch itself. Was strange to look at the first time I checked it out. But the moving gearbox was cool. I know things have advanced a lot since my introduction to it.
 
Scottm you have all the chain rollers and tensioner stuff that's a rare thing. For an 83 anyway.
 
Ive been racing all season so hadnt any spare time or money to get stuck into the husky but ive the motor rebuilt new bearings seals gaskets so wont be long now till i get testing this motor out
