Oops I Broke It

[iron1951]

I was taking my 21W30 apart in order to strip and paint it. First time I have tried this. The last thing to remove was the driving shaft in the head. Trying to press out the bearing I bent the driving shaft. I finally got the bearing out but I had to use  lot of heat and the press. Is there some trick to get this bearing out? This is the bearing next to the thread take up lever.

Honestly - it´s for sure  nice when you fully strip a vintage machine but the chances are high that you break or damage obsolete parts. So I rather leave the parts where they are and I wash out the dirt / grease / gunk either with hot washing soda solution or paint thinner or other solvents and then mask everything as good as possible and clean the "paint splatters" later.... and so forth.... 1st priority on vintage machines is not to damage parts.  My 2 cents

But good luck with this project I hope you can finish it!

Constabulary, I hear you and will go that route the next time. But I had to try. Good learning experience. Never going to do it again. I think that the bearing is pressed in with a special tool and is not meant to be removed. The driving shaft is not stout enough to use to remove the bearing without damaging the shaft. I will remember this for future projects.

School of hard knocks, strikes again.

Lesson learnt.

I'm going for it. Today I (tried) to straighten out the driving shaft. Using my lathe and the torches I straightened it out to the best of my abilities. I then made a plug out of aluminum to replace the bearing, that could easily be removed as I try and error. Shaft spins not too bad. Now to hook up the connecting rods and see what happens. Probably be a few days before I get back with the results. Nothing to lose.

Well I straightened the driving shaft to the best of my ability. Put it back together and there is a slight bind when I turn the wheel but only in one spot. I am hoping the driving shaft will wear itself in. Never fully strip a machine again. Lesson learned.

We've all done stuff that we regret  no doubt,  and I think we can all learn from this. There was a brief  passing ' thought'  of me completely  stripping down my  29 K 53 boot patcher,  shortly after I bought it a long time ago ,  but I'm so glad I didn't after reading that. I think my intuition was on my side back then    I gave it some love  and a good dose of oil and it works just fine . I'm happy with that.

The journey begins. I have stripped the paint off. There was not much paint there in the first place. My pictures seem awful large. What would be a good size in pixels and dpi. Thanks

Kinda reminds me of my 51WSV2  seems they have a lot in common beside smine is a post bed machine.

800x600, 900x1200, or even 400x600 are best for small file size uploads. The jpg quality can be 85% before pixelation becomes noticeable. DPI applies to gifs more than jpgs. Standard resolution, as opposed to high def is preferred for web page photos.

On web pages I create, I usually create two sizes per photo, using the smaller image (~300 to 400 px wide) on page and expanding it with the larger image via a clicked/tapped lightbox script.

Most smartphone cameras no longer offer these smaller resolutions (my Samsung doesn't). So, unless you shoot with an actual digital camera that does allow for small res's, use a photo editor to reduce the dimensions and quality. I use Paintshop Pro, as well as FastStone Photo Resizer to edit images.
