PM Research #7 first model
« on: September 01, 2020, 06:00:31 pm »
Hi all,
I’m really enjoying this so far. My reason for getting into models is because I see the Rapid growth in skills from fellow model builders
I am working on the base, learning how to set up, hold, measure, mill etc.
My skill level has already improved because I’m working off of plans with specific measurements.
In these pics, I am milling the cross head base. I made a tool to determine the center of the crank shaft so I could measure -mill the cylinder mounting surfaces, then I can measure where the cross head tops? Are drilled and tapped.
Is that clear as mud?
Looking forward to the brass!
Always learning

Looks like really well thought out progress from here!

Remember to always measure thrice and cut once, so that you don't end up like I often do, wherein I've cut something three times and it's still too short!!!   ;c)

This isn't my work, but Dean does a good job of showing how he built the same model steam engine here:

^^^Really miss having Dean around... he was the best at explaining everything and had some of the best build threads.

Looking forward to following this build, take plenty of pics along the way  ;)

Yes, Dean is well missed, but at least his website is still up with a whole bunch of useful info available!

It wasn't too long ago, couple of years maybe, that I referenced that while making an ER collet chuck for my lathe.

Success,
The measuring method I came up with proved to  be satisfactory. I was able to achieve the 3.250" cut.
I should be able to make some progress this coming three day weekend. It's forecast to be 111 degrees F.
My shop is air conditioned thank goodness.

He's still kickin' yet as I just seen a post from him on the Coleman Collector's forum.

Yep, last I knew he was still with us ... but he had left us behind from the "other" forum several years ago, never found out why, and hasn't shown back up in any of the normal venues that I've seen. Used to look forward to his posts and the wonderful projects that he often shared with us there.

I still treasure my little rocking piston thimble engine that he made in a batch, but each one was still just a little different .... intentionally!

I was able to mill the cylinder mounting faces with this measuring method.
Now I can mark, center punch and drill for the cross head guides.
Once I drill and tap the eight holes, that completes the base.
On to the brass.

It was a productive morning.
The grandkids are coming over to swim. That’s always a hoot.
Just a few more things to do on the base. I’m happy with my patience and accuracy.
When I feel like I’m beginning to rush, it’s time to step away.

Looks like you are doing a wonderful job, and more importantly carrying the correct attitude to the work. The reason you are undertaking this project is for the enjoyment of the process, and the successful accomplishment of the goal you've set yourself. Neither can be achieved well by rushing. Doing things slowly, carefully and methodically usually proves to be faster by far, in the end!
