Never to many projects or pictures Jim 
what I did today
Today I began cleaning the MM251's MiG gun's liner. I pulled out the liner and managed to shoot enough mineral spirits down the liner with a spritzer bottle adjusted to stream to have it run out the other end a few times... I'm leaving it soak overnight.
Tomorrow I'll run more mineral spirits down the liner and run wire back and forth through it to help loosen up the crud and once more flush it with clean mineral spirits and then run air through it.
While I had the liner out I checked the liner's holes on the end and found they were not perfectly round and the ends were jagged. I should have taken a picture but didn't think about it until after I had already used my scribe and hammer to round the hole and my file to chamfer the ends smooth.
I'm thinking that when they cut the liners to length they come down quick and the heat and downward force of the cutting tool distorts the hole a bit... might only been in my case I don't know for sure, but it couldn't hurt to check your liner's holes for roundness and chamfer the ends smooth to help the wire feed better and when reinstalling the liner.
I let just enough liner stick out of the vice so only the top coil would be forced outwards by the scribe and hammer.
I figured while I had everything taken apart I would make the old nozzle round again too with my long tapered punch... I first lubed the punch so it wouldn't bind in the nozzle and then turned it over and tapped the punch to get the punch free, it worked out nicely.
I measured the hole on a new nozzle and the punched out nozzle and found the punched out nozzle's hole was a 1/16 of an inch larger. Next time I'm going to heat just the damaged part of the nozzle with the torch and see if heat will allow just the damaged area to move outwards. .

If any of you think I post to many pictures just say so and I'll stop immediately.... as far as projects pics go I'm laying off so I don't become boring and annoying to anyone. :good2:

Keep 'em coming Jim. If anyone gets bored, they can move onto a different thread.Never to many projects or pictures Jim
While looking for tools I came across this tool that's used to clear plugged grease zerks. I would like to warn anyone that has one that it's important to know where every zerk is and the direction it's pointed before hitting the tool.

If there is more than one zerk on the same grease channel when you hit the tool a different zerk that may be loose or cracked from damaged can be blown out like bullet and kill or injure you.
I have multiple grease zerks on my 855's brake pedal's shaft, one side doesn't take grease unless I have someone work the pedals. I make sure when I'm greasing the tractor my head is never in line with any zerk....
The picture in away shows what I'm talking about when I say multiple zerks on the same shaft. This shaft is split so the pressure most likely would exit between the shafts.

I finished up the liner today and couldn't be more satisfied with the results.
Before I cleaned the liner and drive wheels I had the tension knob tightened down as much I could without breaking the arm off on the wire drive mechanism and the wire still refused to feed..
Now i have so little tension on the wire I don't see how its feeding let alone coiling the .035 wire at the gun's tip when held almost to the floor.
Instead of using the spritzer bottle to clean the WD 40 out of the liner I made a reservoir out of vegetable can, 3/16 OD copper tubing and some 3/16 ID fuel line.
First I scraped off the coating on the outside and inside of the can.
I cut the copper tube shorter than the #31 drill I used to make the hole in the can.
I used my little torch outfit to solder on the the 2" long copper tube... I love that outfit.
I used Kestler's .020 Electronic Silver Solder because of it's small diameter and the thinness of the can and because I have it in my soldering box. I have used that same solder to repair my reading glasses frames.
The reservoir worked terrifically, I filled the can with acetone and did some other things in the shop while I waited for the acetone to drain through the liner. Not having to fight with the spritzer bottle was worth effort.
The pics of the wire drive wheels are after their acetone wash.
I showed my new John Deere rotary cutter blades to let everyone see how rounded over new cutting edges are. When resharpening your blades remember knife edges don't last.
Next job is to bed liner the 855's foot boards and back and the underside of the seat . I'm thinking about doing the access panel over the drive shaft and down the sides to the foot board with bed liner too.
13 pics coming, thanks for looking at them. :hi:

I'm told I'm an "old guy". I refuse to meet those requirements, lol.
May 10th 1952 was quite a day, (as far as I'm concerned), but, my mantra is: "I may grow old, but, I refuse to grow up".
Been a lot of places, seen a lot of things, done more in one lifetime than most could hope to do in three, and still looking to add "quality of life" to those around me who will take the time to slow down and listen.
Peace be with you......

Same here compadre....I am constantly told to grow up. That aint happening. Close to 20 yrs ago I became a grandfather at 40 yrs old. That was the year I decided it was time to get back into dirtbike racing. I just sold my last dirtbike a couple of months ago....but only because my riding buds quit riding...or I probably would still be doing it. I do have to admit that it was getting to the point where crashing was taking way too long to recoup from my injuries.Bones especially. But...it was fun to school some punk hotshot every now and then....but that was becoming rare lately.I just dont have the stamina anymore. Some people think its easy to race a motorcycle offroad...but they have no idea. The best thing to describe it in a way they might understand is, imagine riding a bucking bull for 2-3 hrs (usually 80 mile races). I still love to be in the woods and outside, so my tractor helps me satisfy some of that ....just at a much more relaxed pace.I'm told I'm an "old guy". I refuse to meet those requirements, lol.

And peace be to you too!!!
All three of you are kids. I've got a lot of years on all of you and I ain't real big on the growing up either.:laugh:I'm told I'm an "old guy". I refuse to meet those requirements, lol.

Also not big on retirement either, but that's on another thread.
