Canadianhorsepower's build of Rupnow engine

[canadianhorsepower]

Luc - I love the method in post #28. An old timer showed me that over a decade ago when I was fesh out of trade school. Been using it ever since. Very effective too!

Nicely done Luc! My compliments!

Thanks for the kind words, keep motivation to the top

ARRRRRRRRRRRRRRRR I feel like a tigerth_wtf1th_wtf1th_wtf1

doing all kind of measurement with my new DRO on my lathe
sometime .0001 on sometime .250 off :hDe: so I decided to investigate tonight. and MAN a broken glass scale. call the company because I cant explain why it's broken, GET A NEW ONE.:fan::fan::fan::fan::fan::fan::fan:
and pay for it IT"S NEW

I'm running out of fan and they are not pointing at the good place

Very unfortunate Luc. Those are not cheap.---Brian

Are they going to replace it? Don't forget to check eBay if you have to buy out of pocke!

 

[canadianhorsepower]

Are they going to replace it?

of course not their mantality I cant prove them that it was broke
or deffect when I got it. I'm going to replace it with a magnet scale instead.

What i worry about the most I still have 5 more of these installed on other equipement. The good side is that only thisone was giving me a hard time:wall:

 

[canadianhorsepower]

Hey guys, here are a few more picks of this project. I got the cast
Thanks to Brian, the Viton ring, the gear and some shop time. As you will see in the pics and the one coming I started with the cast in the lathe
and it stays there for the complete machining.

After machining the cylinder itself I was under the impression I was GOD'S brother:hDe:, or just as good. In the bible he's multiplying bread, whine and fish. Well I did the same thing today I started with a 6 pound piece of cast, and manage to get 20 pounds of chip from it and still have my cylinderRof}Rof}Rof}
enjoy the pics
I'll set up the boring bar tomorow

Going well Luc, I hate working with cast iron. The dust gets into your skin, up your nose and anywhere else it likes. I'm pushing ahead with a steel cylinder with an aluminium finned sleeve.

Looks really great Luc. How come you bought two sets of bevel gears?---Brian

Brian,
those gears came from GBS and they sold them to me at 24.?? each
including shipping. I think it was a good idea to have some sitting around
I know that one day I'll use them even if it paper weightoh:

here we go on the last update, cast cylinder is all done many pics but worth it
Sure missing my DRO. tomorrow a honey do list

 

[Brian Rupnow]

That's a beauty Luc. Congratulations!!!---Brian

 

[canadianhorsepower]

I forgot to add some pics yesterday:wall:
here they are

 

[Brian Rupnow]

Luc--Great pictures. Please tell me more about your adjustable reamers. How much is the adjustment range on each reamer, and what does one look like.---Brian

 

[canadianhorsepower]

hey Brian--
in the first picture is the complete set I was talking about
in picture 2 is the reamer I used, as you can see they are still in plastic bag
I don't use them often so when I'm done they get a shower of lubricant
in picture 3 is the reamer and the dial-bore gage I always use them together picture number 7 is the small pre-set length gage that goes on the end of the bore gage as you can see they are very precise . In pic number 6 you have a close up view of the adjustment for the reamer. The way it's done is by tightening these nuts (one on each end) is move the blade up or down to
what ever you want size about +/- .125 . now the procedure that I do is this
I use the insert size bigger then what I need let's say .880 set my dial to 0.00 then when I insert the end in the cylinder I can read let's say-.30 this is telling me I have a bore of.850 and in this case I wanted to have .875 so I ream till I get -5 on my gauge
last picture is the reamer inside the cylinder itself when I'm done I run to the frids and get *beer**beer* it's a long process but well worth it. a complete kit is fairly cheap 120.00 or so

enjoy

 

[Brian Rupnow]

Thank you Luc--I had not seen those tools before.---Brian

 

[starnovice]

So now I have to ask, how does a dial bore gauge work?

Pat W

Pat-- it a fulcrum at the bottom that pushes up on the dial gauge.
because of the throw you have to put pins to compensate for the
diameter of your hole. instead of using snap gage and a micro meter
you can use this
