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

[Constabulary]

 

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.

Constabulary, nice looking 51W. Like the wrinkle paint. Your 108W20 was also done in wrinkle paint. Have you done any restorations in another paint? I would like to see some pics before I choose a paint. Thanks

Wizcrafts, what do you mean by standard resolution? I use a photo editor. I can create a new image, width, height in pixels and resolution in dpi. Would standard resolution be 96 dpi? My photo editor allows resolution range 72 to 600 dpi. What would you recommend? Thanks

I use irfanview (free) to resize to 800x600, you don't want it too small 'cos we voyeurs like to see some detail.

Your photos look fine to me.

96 dpi is fine for forum use. It will reduce the file size to stay within the forum's upload limit.

I don't know about InfranView, but Corel's Paintshop Pro has additional "Chroma Subsampling" optimizations for reducing the filesize with minimal loss of clarity. As an example, I loaded a 1648x1004 px jpg into PSP and began optimizing before re-saving it. Using 15% quality reduction, along with Chroma Subsampling of YCbCr = 4x2 1x1 1x1, the original file gets reduced from 4.34 mb to 346 kb - with barely noticeable artifacts in a few dark areas !!! The DPI on this image is 300.

@iron1951 You are much braver than me to pull the whole thing apart .  No doubt you have good knowledge of machines to do that. 

But can't wait to see the finished product though . Good luck

P.S. Can't help but notice your " secret stash"  of toilet paper in the last pic.   

[iron1951]

Constabulary, your restorations are works of art. Do you use textured finishes to help hide the pits in the castings? Do you prime and sand before you paint? Did you use a buffing wheel and a buffing compound to shine up the metal? This is my first total restoration. I hope you don't mind the questions.

Wizcrafts thanks for the help with the pics.

Handstitched, I take lots of pics during disassembly to help with assembly.

[Constabulary]

Well the textured paint (VHT wrinkle) just looks cool I think and yes it covers pits and chips very well just like the silver hammer tone paint. The silver hammer tone silver always looks "fresh" I´d say. I really like both! On the 108w20 I only have touched up some on the larger paint chips the rest is still the original paint. I have not primed the machines I just clean them with pain thinner and sand them with 240 grid before painting. I do not buff the parts (I do not have a buffing wheel). What looks like rust often is just dried oil and dust. Often a hot washing soda solution can wash down this gunk. The really hard necking stuff on certain parts I remove with a round wire brush for electric drills. I`m also using electrolysis for removing paint and dirt sometimes.

Lot of good information here. Thanks

[iron1951]

Here are some pictures of the paint. Next time I have to be a bit more careful as I have paint "shadows" in a few places where there were plugs.

[iron1951]

Of course, I had to have an accident when placing the machine into a table. I did not notice that the bed was shorter than my other machine and the 21w30 fell breaking Take-up Lever. Part number 203270 (or 203271 complete). Anyone have an idea where I could chase this part down? Thanks

[Handstitched]

@iron1951 Very well done on the restore,  the paint job looks great   but pity about the take up lever,   . If you can't find one, would welding be an option, if they can be welded ? 

Good luck 

HS 

[iron1951]

Handstitched a couple of people have suggested welding. I was actually doing the welding while you were posting. My take up lever is cast so I brazed it. I am pleased with the results. Seems sturdy enough. I couldn't make it any worse. Pop over to my other post "Can anyone help me find this take-up lever" for pics. I started a new thread because I thought I would get more responses.
