Thread: a much needed restoration WIP

nice old plane

Looks like its not in too bad a shape look forward to the final pics. I have two of these that need restoration too.

Whats in the bath, vinegar?

Looks like a good Carter Rebate Plane.
Jeremy did a restoration of one of these on this thread:
https://www.woodworkforums.com/f152/c...e-plane-42554/
The Carter is a very robust rebate plane with an excellent blade and a generous mouth. It can be used to remove timber quickly in planing rebates and has plenty of heft to get it done easily.
This is Jeremy's finished plane

Also here is a very nice example of what yours used to look like:

The bath, I wanted to try witch1's recipe with the soda, but only had bi carb soda (baking powder) had a look online to see if that was the same or not, no real answers, anyway didn't want to wait so bi carb it was....(can't hurt can it)??? in went the vinegar and that made quite a reaction lots of fizzing mmm not sure whether that's good or not, add about 3" of water and in goes the plane and bits, not much reaction that I could see, leave it for a bit, not much happening, no chemist here but I think all that fizzing neutralized the vinegar
Tip it out and start again, just vinegar and water, probably only about a 10% solution and there seemed to be a little bit of activity on the metal....so left it overnight, looked at it this morning and looked like nothing happened......but wait there's more, give it a rub with the finger and ahhh looks like a result ......a few pics......

I just washed it under running water and a stiff brush

some pitting and a few marks

I think this will come up well

From the reading I did yesterday hydrogen embrittlement seemed to be of concern...so into the oven at 150 for an hour or more, good for the embrittlement thing but no good for the original paint which I wanted to keep as is, oh wellalso the lapping and the convex issue, think I'll revisit the past with some scraping and see how that goes, just need something for a test surface, I have some float glass and a granite? top
Do you guys think it will be flat enuff?

G'day Pete,
You just neautralised the vinegar with the bicarb on your first run The vinegar looks to have done a good job tho. You really need a good straight edge to check your granite and glass if you wwant to use them for the transfer. My granite offcut is way out. The 12mm float glass is better, but still wavy enough to cause problems on transfers to longer planes (either end up with spurious results when you reach the tolerance of the glass or end up making a perfect match to the wave in the glass)
Cheers
Michael

Yep

Yes, I have a 2' steel straightedge, they say it's accurite to within a thou over it's length so I'll check plane first, never know it might just need a polish without too much removing
and I'll check glass and granite and make decisions from there....


Pete

Did you use electrolysis because I thought it was only then that hydrogen embrittlement was a problem?
Cheers,

In so far as hydrogen embrittlement is caused by molecular hydrogen ie H2, both processes, electrolysis and acid reaction liberates hydrogen and therefore might cause hydrogen embrittlement.

Whether this is a problem with cast iron in a practical sense, yes and no. That's what I read on the internet so it must be right!

Thanks Michael

Thanks Micheal, cleared it up for me as well, I would have had to read the info again, memory like a siv these days, I did also think that it would be good to dry out any moisture lurking in holes and under any remaining rust flakes or paint, the day wasn't hot enuff

Pete

Sigh. Hydrogen embrittlement is only going to be a problem if you have high alloy steel - the closest you'll get to this on a plane is the little bit of spring steel that tensions the release doodad on the lever cap.

Mild steel and cast iron in a hand tool aren't going to be stressed enough for it to be a concern.

Well there u go! Just goes to show u can't trust everything one reads on the net
