Title: Bruce's Rupnow Engine Build
Post by: bruedney on November 01, 2016, 07:58:13 AM

Well after a number of weeks of waiting for the MT2 reamer from the UK to fix up my mill spindle (Thanks Arc Euro for Fedex backup) I have finally started making swarf again.

The weeks were productive though with all of Brian's drawings redrawn in metric.

So today I made a con rod

Measure twice - cut once the saying goes

The "practice" version was profiled in 10mm aluminium  :facepalm:

Then I got the mill working on the real piece

The final version all cut out

This engine is a lot smaller than it looks.

Thanks Brian for the design and the drawings

Hi Bruce--I am thrilled to see you on board with my engine. Yours will be the fourth build that I am following. It is a great engine, and you will probably get many requests for the plans in metric. Good luck,--Brian rupnow

A little more done

Crank web and con rod, pin and retainer done.

Also cut a big block of expensive ali (7075 - I think) down for the frame and cylinder mount. That took quite some time.

Things have been a bit busy of late but I have made some progress.

The big chunk of Ali has been sized and then shaped

I need to get a long reach end mill to hog out the gap in the frame so I thought I would move on to the cylinder

After cleaning up the Cast iron and turning to size I decided to cut the fins before boring the cylinder out

Thanks James

As you will have seen, no I wasn't at the meeting. My wife is heading down to Kaikoura early tomorrow morning to provide support with work so I decided to stay home with her.

I did get a little machining done though.

Major machining on the cylinder all done. Just need to set it up on the mill to drill and tap all the holes

Workshop night - Wife is away for 6 days with work so I got to do a far bit of swarf making tonight

Mounted the 3 jaw on the mill (poor man's rotary table - not a big deal with CNC) and centred the cylinder and drilled and tapped the holes on both ends
(https://lh3.googleusercontent.com/EqE8vHlhfaS3_-xSGi4u4XzZ54FrpWihOSIU5NNlUa5nS8t0Mo_9eonjT792z5kanuZN_ApP8Jlh_FOz_npHm3gXFcj4YHGRsJEnBeR7kPGYjpIQQMkDbKp8uoDJcDUUdA8bvpYqkRgUs_yk_-Mb895nx6QCUmMZgA5DLGMCdWum2bnSIZZiB9Gb4G-vT7mIdya3ciEExtK_uaHyy0iTGnrPiIMe94AWy9HpSBCmGexjR4GKOJVSzFnf1AZl-63sw02v4W-qeJwWTqc8_R9apgCfWik5W82ylSAuzJ9LbCvjGcb_rVisK_wtpVFHX8YYy-3SJagV2J612jHxAHKVaBMwuPPiJb1WszmB9zwCyImOONIke_BgCNsGvK2sNEQGIYdANOGklhDMIBSYkD0sDQJnZLcVO78EoQk3QkKmJ4ANmTc9rdek8OLZeeDUR1pfGlsycRC54_DOtrHuHMcY7RLIOQascJgGwCP6ktgvqDoyc_lMs1MtzBDPesfl7XECyxhTH7dpbzEYT-0AvqRK6pvAiL1w4_gv8jqZ9yYEk4tQD5eYKzPhKDHzeVTn-toUYzgBGMSMgGLlulhs8l95AB2lD5hjasEHpnhDQjhV8BBsyiT4k74K=w800-h600-no)

Then I chucked up a piece of tooling ali in the 4 jaw and started the piston.

Part way through though I found that the carriage on my lathe was lifting. So I stripped the cross slide off and skimmed a bit of the carriage gibs to remove the play. Much nicer

Here is the piston ready for some milling and drilling operations tomorrow night.

"Well the best laid plans of mice and men"

My plan was to spend heaps of time in the WS due to the boss being away. But work has got in the way to a certain extent.

But I got a bit done this evening.

Got the piston all set up to drill the wrist pin hole and then turn 90 deg and machined the slot and grub screw hole.

Then machined the wrist pin and fitted it all together

It is starting to look a bit like an engine  :whoohoo:

Hi Bruce, like the idea of turning the piston from square.
Was up in Wellington last week, came home to Canterbury on Thursday, and hoped to get a view of the coast on the way south (Jet Star), cloud all the way.  A week or so and the road Chch to Kaikoura should be open to one lane traffic.

I have been working on the JAG Carb

What a fiddly little beast it is

First attempt was binned due to square stock not being centred correctly on lathe

Second attempt has almost been binned due to metric conversion errors but hopefully all will be well (should have moved the Air bleed screw away from the centre bore a bit more)

Here is a pic of yesterday and today's efforts
