That's looking really impressive Mike, I am looking forward to seeing it at Guildford in a few weeks time 8)

Talking of attending the Guildford show: It doesn't look like our mutual friend will have anything new to show again this year  :disappointed:. He is currently up to his arm pits in Engineering Microscopes  :headscratch:

I tried to encourage him back on to the straight and narrow by forcing him to get out his model engine casting sets but it didn't work  :ShakeHead: The best I could do was confiscate a set and bring them home to make them feel wanted and loved.

Mike,

 Once you had the 3D printed part, did you consider doing a lost wax of it instead of machining it?

Cheers,

 Wilson.


Ps. Amazing work BTW.

Jo,
I am also looking forward to the Guildford show, it's one of my favorites. No surprises from our mutual friend then, he does love his 'wheeling and dealing' just like Del Boy.

Wilson,
Yes, lost wax casting is a possibility. Unfortunately I do not possess a lost wax foundry and the only commercial foundry (that I know of) who are prepared to do one-offs for model engineers, in this country, have a £500 minimum order. Clearly they do not really want the model engineers work. At that price, you would need to be absolutely certain of the correct allowances for wax shrinkage, post burn-out investment shrinkage and of course the cast metal shrinkage. It can quickly become a very expensive learning curve to determine these allowances.

For those reasons I chose to machine everything from the solid billet. I know the properties of the material I work with and I control the dimensions of the finished part. The only other cost is my time and I provide that for free, for the enjoyment. Besides, I can claim the model is ALL my own work.

Mike

Hi Mike,
 Have been really enjoying your work.....outstanding !

Make's this lesser mortal think about selling up the workshop as there's not enough time to left to get close to being in your class.....still like you say it's all for enjoyment at what ever our level.

On the lost wax casting front, have those guys not worked out that there is a large potential market out there who may just be ready to take the plunge if the costs seems reasonable........or maybe there is somebody who does this as a hobbie & would like to move into full time .

Looking forward to the next installment

Cheers Kerrin
Get excited and make something!

Thank you to all who have commented on the latest installment of this ongoing project.

Just remember:
Experience is directly proportional to the height of your scrap pile.
You learn more from your own mistakes than from others.
But never forget that experience also allows you to make the same mistakes again, but with more confidence.

Which reminds me Mike :embarassed: I was going to take along a box of " the bits that didn't make it on the model" to the Guildford show. If you feel brave we could add some of your examples.

P.S. Jason can't provide any because he never does anything wrong  :mischief:

Been there, done that ..... and continue to do so   :ShakeHead:  :facepalm: .... though I still have to get around to do so with model engines - ... it looks like I'm getting closer to start doing so in that department too   :noidea:

Life always looks a whole lot better from the door into a model engineers workshop. Keep us posted

I have some pictures of the camshaft, crank and rods if they are any help when you get to those parts.  I could probably also get measurements if needed.

Simon,.

Do you really have photos of the crank, camshaft and rods for the W165? I would appreciate if you would share them with me.

I used to be able to obtain a (very) limited number of photos of the W165 engine restoration work at Fellbach through Christof Knetch and Gert Straub but that source has dried up. How good are your connections with the Classic Centre at Fellbach? There are a number of photos in their collection that I would dearly like.

My e-mail address is in my profile information. Perhaps it would be a better to correspond there, rather than clutter up the forum.

I'm already getting excited

Cheers

Mike
