40 HP Avery second phase of rebuild

[40avery]

The 40 Avery project is in the mechanical disassembly, cleanup, and repair phase. The rear drivers are being worked on. Many of the lugs have a lot of scale build up under them that needs to be removed. The rivets are removed the lugs taken off and then after the scale is cleaned the lugs are re-riveted in place. At this time I do not have pictures of this process.

This is a picture of the Engine with the main shafts and crank shaft removed. It is being disassembled not only to rebuild the components that need it but to be sand blasted and painted.

This is a view of the bearing protectors that are bolted in to cover the babbitt. When sand blasting - sand tends to get where you do not want it if it is not well protected.

Looks like you guys are coming right along!

Why didn't you sandblast on Saturday? The crew I was with was thinking about how much fun you guys were having sandblasting... and then we heard that plans changed for some reason! :rof:

Thanks for the pictures Rick. It will be fun to watch it going back together.

[40avery]

I can imagine that sitting in Jim's warm shop eating donuts and watching Kenneth work was trying for you guys.

Aside from the cold weather we only finished the disassembly at 7:00 PM. There was not enough light at that time for a good start so we went home.

Hi Rick,

The work looks good. I am looking forward to seeing more about the rebuild of this tractor and to see it running.

Later,

Rick,

Glad to see you folks making progress on the 40hp Avery. Where are you working on it at. It looks awfully cozy in there. I take it that all of the necessary work required on the boiler is done and you can now devote your time and energy towards the running gear. Thanks for the photos, they are great.

I'm glad to see the Avery project under way again. Thanks for the pictures Rick. It sure is good to see it in good hands, and being restored right. Speaking of pictures I found another picture of the Avery at Mt. Pleasant with Leon Farrie and I, wow I looked young back then.

Hi Steve!

Great to hear from you again. I will make sure Mark sees the picture. I really hope you will be able to come and see it in '11. It must have had some attention paid to lubrication because most of the babbit seems to be in good shape. I am anxious to help with the building of the new bunkers but that will be a little ways off yet.

To step in here for just a little bit...

Mark Pedersen was in Fargo this past weekend working on various parts of his Avery engine. I know the cylinders were bored, but I am not sure of the details. Larson Welding did that work. Kelly Muhl was also there working on the reverse valve linkage, cleaning it all up and freeing up all of the moving parts. I am hoping Louie got some pictures of that operation...

I got involved a little helping Mark machine the reverse guide parts. They were badly worn, and Gary at Larson Welding built the guide blocks up with cast iron. Mark said it was the most beautiful job of building up cast he had ever seen.

Here is a picture of one of the reverse guide blocks after it was built up, before machining.

http://i155.photobucket.com/albums/s317/mbkerk/WMSTR/pedersenavery6.jpg

Both the guides and the blocks had to be machined. Mark used a jig for the vertical mill that Jim Briden had built many years before. They dug it out, blew years of Larson Welding dust and grime off of it, and pressed it back into service. The guides and blocks are not machined flat. There is a radius on the machined surface, so that all had to be figured out and determined how the jig was made.

It is quite a process to set the parts up for machining. You can't just clamp it in and go... Mark used a dial indicator to "dial it in" (bore on the block centered to the end mill) and got it within less than 1/1000 of an inch before the process could start. Those who know him know how fussy he is, but the end result is worth the time it takes to do it right.

I have a couple of notes in the picture that will help you to understand how the jig and the end mill works. Also you can see Mark checking the width of the finished block with a micrometer.

Below is a picture of one of the reverse guide blocks after one side has been machined. If you look in the background, you can see some brass filings from the same process being done to the guides. The same jig was used.

http://i155.photobucket.com/albums/s317/mbkerk/WMSTR/pedersenavery2.jpg

A few of us were pressed into service to slowly turn the crank on the jig. Each side took 17 passes .01 at a time to complete the process. Here Tom Seaberg is taking his turn at the wheel!

Below are the finished reverse guides. I did not get pictures of them during the machining process.

And a picture of the finished parts as they will be installed on the engine! The fit is perfect... a testament to the careful planning and setup by Mark and Jim on the mill.

I was just looking back at Ricks pictures at the beginning of this thread, and you can see one of these blocks in his first picture...

Engine was 1/2 apart when Mark got it, and when you see pictures like this it kind of gives you some perspective about what an undertaking it is to get it all back together! All of the parts were thrown in many boxes and on pallets!

Mark K.
Thanks for the pictures! As I have said before you guys are doing a first class job an the Avery. Sure wish I was closer to lend a hand.

Last weekend the Avery was worked on again. We had a crew together that riveted 51 lugs back on the wheels. We had originally removed 50 but found one more to remove last weekend. We also replaced one spoke rivet on one wheel.
Mark also brought the freshly painted frame in and started assembling the engine. The cylinders were reinstalled on Saturday and they were going to try to install the crankshaft on Sunday. I was not there Sunday so I do not know how far they got. I will try to post some pictures of the work that was done on Saturday.

Mark is doing a very nice job on this engine. Sometimes when working with Mark we need to :imnotlistening: but at the end of the day we all :not_worthy:.

Jerry was in charge of heating rivets and keeping Wimpy awake I will explain that later, Jim got a hold a hydraulic rivet machine that has a remote control for operating it Which Wimpy was in charge of

[louie]

http://i173.photobucket.com/albums/w54/louie14steam/40hpavery004.jpg
I tried to get a picture of the rivet before it got set but Wimpy was to quick for me. This is eally a neat tool to work with after a few trial runs on some scrap the pressure was set at 400 lbs which set those rivets like they were hot butter

Every once in a while Jerry would have todrop a hot rivet down Wimp's pant's to keep him going:rof::biglaugh:

Setting cylinders on to engine frame

[M Kerkvliet]

Wow! Wish I could have been there!

This thing might actually be a runner by 2011! I think all involved are happy to be part of this restoration!

[James Maxwell]

Wow! Having driven the other 40, the smoothest most powerful engine not on rails I've ever had the pleasure to operate, it is awesome to think there will be another one running. This is why we keep these things running. I may need to find a way to get out east around 2011 I do think.

[Pete Mandt]

Here are some pictures of the 40 Avery wheels before repair. We ended up removing a bunch of the lugs that had scale and junk built up underneath them.

Great sequence of pictures Pete. Thanks for helping keep up the posts on this project.:thumb:

Rick

[M Kerkvliet]

Good to see you have the picture posting thing down Pete! We expect a lot more from you now!

The engine is looking great! I suppose things will slow down soon as farming will start up and everyone will be busy.

[KEVIN SMALL]

Is Mark P. going to fabricate a set of extension wheels for the Avery?? I just like the looks of an Avery with the extensions than without. Great job on the restoration so far and like many others, I wish I lived closer to lend helping hands!! :thumb: KEVIN

[40avery]

Mark has a set Kevin.

[KEVIN SMALL]

Thanks Rick. Did the extensions come with the engine from Mt.Pleasant,Iowa?? I don't think I have ever seen a picture of this Avery with them on. I am going to go through some Iron Man Albums tonight. If I recall correctly, there is a two part article on the Avery written by C.R. Willits who was the owner of the Avery at that time. I just can't remember which issues the articles were in:bonk: I will try and find it ! I would assume that Mark knows the history of this Avery already?? It was a very well written history by Mr.Willits. I'll let you know soon! Thanks again!!:thumb: KEVIN

Kevin,

The extensions did not come with the engine from Mt. Pleasant. Mark had them previous to him getting the engine.

[KEVIN SMALL]

Rick,
I found the three part Iron-Man article titled "Memoirs" by C.R. Willits in the July-August, Sept-Oct, & Nov-December 1959 issues of the Iron-Man Album referring to this 40HP Avery. It says this engine was bought new in 1913 by Mr. Harold Lucas. It was used in Tonkawa,Oklahoma for plowing. I am not very familiar with Avery serial numbers, so would this be a 1913 engine? The article also states that Mr. William Merhoff (who ran the engine when it was new) insists that it is a Canadian Special. He said there were reinforcements around some of the outlets that were not present in the 40 HP Boiler and there was some heavier plate in the dome. Hope this helps
KEVIN

[steve kunz]

Here is a link to the main part of the article on the Avery that Kevin is talking about. http://steamtraction.farmcollector.com/Steam-Engines/MEMOIRS-November-1959.aspx
I have read this article before and enjoy it every time I read it. There is a little bit left out that is in the actual magazine, like when they were stopped at a weight station in missouri and there 1 ton truck was overloaded. They had to leave one of the wheels and come back for it the next day.

Thank You everyone for the effort on this project. From some of the first pics where I recognised Rick out @ Mark's farm yard getting boiler ready, to some of this winter's pics & stories at Larson welding again w/ so many familiar faces; Kelly on the stay bolts, Mark P. himself & others. It really helps me get thru the winter -- looking forward to Rollag this June to spend Fri-Sat_Sun on the Working Weekend.
