RFB
way back when, I started on mastercam 286 which is really old. it ran on an old 386 computer. man was that thing slow. all I had was a slim manual and no idea what I was doing. it was the first...

RFB your model Looks good. in fact it looks very much like the real rotor design of a roots blower with the lands on the ends of the lobes. although I didnt understand most of your explanation and...

nowhere in this statement did I say that the Fanuc was intuitive. Im sure a die hard mits guy would find the Fanuc a PITA, which is how I feel about the Mits control.



on a side note heres the...

The mits is not really a pos. Its just really foreign to me after running fanuc based for 27 plus years

ok your lathe is about the same size but is your mill 30x60 table travels too? my old mill was 16x32. served me very well for the last 10yrs. but decided to upgrade. gotta say I am happy with it. Now...

ok that made my head hurt after reading it. way more than I need to know for this little hobby engine. however if I were going racing Im sure id want to know this stuff. glad somebody here would be...

I think I am going to have to remake the rockers though. it looks as though Im going to have more lift on the cam than the rockers will allow without binding. not a big deal. but its a step in the...

heres a couple pics

Dyno,
not surprised you jumped in here. glad to hear from you. one thing to note. the big reason small engines can rev higher is less reciprocating mass than its larger counterparts. the bigger ones...

power estimate is unknown. there are so many factors it would easier to throw darts in the dark. My lathe is a Mori Seiki SL-15 with live tooling. yes that is a wire edm Mitsubishi DWC-200H. in fact...

I have made a little progress. not anything really amounting to much other than buttoning up some of the small things. I got the intake and exhaust ports done in the heads as well as the ports in the...

AMC somewhere there is a place to subscribe to threads, Ive seen it but cant find it now. as for shop space. figure out what you think you need and then double it. no matter how big it is. its never...

well, the build has been put on hold due to setting up the "new" shop. I had a lull in the work load over the holidays which I took advantage of and moved the rest of the machinery along with all the...

something is better than nothing. are there any other 9000 series programs in your machine? thanks.

Just bought this machine. from what I can tell everything works except the tool change routine. after doing a bit of research it appears the 9000 series programs were dumped somehow. along with...

actually, from where I took the picture there are 3 cars behind me. (BMW, Honda and an Opel) what you see is half of the length of this section of my building. the width of the room in the pic is 1/3...

An update on the shop progress.....
heres a pic of where my equipment is going. still need to do some work yet but its getting closer. the new to me mill will be here on Nov 1st. where I am standing...

sorry man I got nothin right now. been busy with work etc. too many irons and not enough fire to go round. I havent abandoned the project just been uber busy. been working on the shop too, prepping...

Loctite is a great product however it does have limits. the one thing to keep in mind when you decide to use loctite on something is whether it will see heat and how much. enough heat will make ANY...

Thanks, When I started this project I knew it would be lots of machining. but it was even more than I anticipated. I dont mind. I just didn't evaluate it to the extent it really required. but its...

Bluejets, well said. and good advice.

I have to say yes to that. I always get a thrill when I make all these different pieces according to a print or CAD drawing and then it actually assembles like its supposed to.

As Dynosor pointed out the parent design never had any consideration for balancing. Also its primary use was not something that would be run more than a few minutes at most at shows and for the...

whos knows, maybe it was possible. at this point though I am satisfied with what I have. once its running maybe I will change my mind and seek a more balanced crank.

Dynosor,
I have been taking it easy this weekend. had the boys out in the shop getting the other end of the building ready for moving everything down there. had some misc junk cluttering up the...

Yes it does turn over by hand. of course with the pistons in the cylinders there is more resistance but still easily turned by hand. I have not turned it over under "power" the other engine has the...

here's a picture of the lower end assembled. the rings are not installed yet. I still have to make the fixture for them and get them heat treated. maybe I will see if I can whip out the fixture today...

Dynosor, Thank you for the detailed explanation. Had I attempted explaining, I don't think anyone would have understood anything other than I clearly didn't know what I was talking about.

Fannblade,
I suppose if the press fit is not sufficient I could add a set screw for each weight as a mechanical means of retaining the weights in addition to the press fit.
