Chain Drive rear spool

Waterjet guy says it's hrs probably 1020. It will be carb. hardened not sure what rockwell yet. I need to do some research on what everyone else is doing. 50/55? just guessing.

Is there any advantage (other than availability) of water over laser in this circumstance?

[Rick S.]

A laser would have trouble cutting tiny splines like these in thick material. Too much heat.
I do have access laser, plasma, strippit and waterjet.

Cheers

OK.... what's a strippit? (NO Yummi!)

[Boostinjdm]

It's like a nibbler, or a punch that moves around.

[Rick S.]

It's a very large high speed punch press. One of ours even has a laser head in addition to the punches. It punches all holes and lasers the contours. It can also do countours, but they do look nibbled. The accuracy on hole relationships is within .005"

and you all wonder why this guy can build such highly detailed machines? Its all in the machines making jobs easier and more professional.

Oh, and a little bit of skill goes a long way to  (probably quite a lot of skill actually, but dont tell Rick that, I think his head is set to swell...)

As some of you may have guessed Im quite a fan of 'doin stuff'. There is nothing wrong with throwin the cheque (correct spelling) book at things to get em done. But I am extraordinarily impressed with guys who start from scratch and MAKE stuff.

Its what I try and do but my limited abilities only allow so much.

Rock on all the engineers of the world (and particularly this site!)

Not in the U.S. Why is the spelling different on certain words. even all these english speaking countries have their own twist in words. Check and Cheque is a great example of this.

Ahh oh well.

Artie... in responce to your post, I have to agree. I love seeing somthing made from nothing. Thats why I like doing what I do! Allot of satisfaction.

[Reidy02]

Yeah I'll third that motion, I think it is, I do alot of trying and get a bit done. ah well I'm have'n a go!! And gett'n better sorta! I guess that's a matter of opinion huh.. Oh and tyers and tires Doug, then there's colour and your way!

Gonna have to ask youself that one mate. After all its you guys that heve elected to spell things differently to the rest of the (ENGLISH speaking) world...

[artie on edge]

AluminIum thats the one I have most difficulty accepting.. not real fond of your version of tyre either.. or cheque... realise with an S for gods sake..... jayzus!

Sorry, back to topic.....

[Rick S.]

I'm Just about finished with this project. Here is the 15T dual sprocket mounted on the weld jig. I cut a small groove for the tig welding the two halves. 3 dowels and a small WJ spline slug help to hold the correct alignment between halves.

[Boostinjdm]

Looks pretty good to me.  Who ya gonna bribe to TIG it?

[Rick S.]

I have a welder at work that needs some machine work done.
