well done nick, what next?

.

Thanks Gary,

First I need to finish off this one with the tank mounting and cable tidying etc while it's still on the bench or it will never get done and properly finished. Engine is also running much better now.

As for 'what next' ……….. I don't really know. So any suggestions anyone.??

Congratulations Nick.

Now we need the rest of your 'chopped hog'

Hi, I too am building the Hoglet. I am using my Arduino based dividing head to cut the gears, and next will be the cams.

I wondered if anyone had a spreadsheet of details for milling the cams. The drawings have limited information and I don’t know how best to proceed.

Regards, Mike

Well you could forget the Arduino and do it as per the build article. All the info is on the drawing for milling them that way.

Something like Cam-Calc would generate cuts at 1 degree spacing though I'm not sure if that does radius flanks or just flat ones. Even with that and your dividing head you are looking at making several hundred very small height adjustments to the mill so much longer than the boring head method

Where are the plans available for this little engine ?

[JasonBModerator @jasonb]

Issues 10 & 11 of Model Engine Builder mag, you can buy digital back issues. It's a bit of an odd arrangement to order them but just go to subscribe and you will get to the back issue order page after a couple of clicks

Thanks Jason. maybe a single cylinder engine would be good to do first.

[Mike BlankleyParticipant @mikeblankley]

Thanks for your reply Jason.

I have reread Randall Cox build notes and have tried drawing an enlarged cam on graph paper. With my limited knowledge, I think I will buy Model Engine Builder no.7 which shows making the cam for his Open6 engine.

Regards Mike.

Nick,

That's very nice and it sounds great.

Mike,

I'm happy to have a go at putting the data you have into my camcalc spreadsheet. PM me if interested.

Cheers both,

Rod
