Screwed up my MF #85 - Looking for suggestions

>Sorry to hear this Denis.

I wonder is the metal-filled epoxy sticks would be strong enough to cope with the demands of a nicker cutting into wood? It would be a simple matter to fill the hole and tap a new thread in the correct position. Can one spot weld the hole and tap?

>There are a couple ways to get it out, but what I would do is take it to a machinist. Those guys can do anything, at least mine can. Or find Forrest Addy's email address and send him a message. He's a machinist and can do anything.

>Denis, can you post a picture of the patient? This would help, but on the face of it I am sure that a clued up welder can "place some metal there", then you can re-drill and tap for a suitable screw.

Do nor despair-nothing is broke (yet).

>This is a rather common plane that can be picked up cheap.A quick look on ebay showed what looked like a nice one missing the fence rod,[had the fence] and depth stop getting sold for less then $10.00. I would pick up a stripped body and use your fence and depth stop and stick your wifes grandfathers rusted busted plane body in a place of honor, [maybe junk pile behind the shop?].

Sure maybe you can hobb it together, hey maybe you can even find a welder or machinist if you travel to Bangladesh that can sort of fix it cheaper then what it will cost you to just buy a nice replacement but in the end what will have?...A repaired messed up plane. When you can have a good not messed with plane so cheap and with out all this trouble I would think this would be an easy choice.....Todd

>If its in the body, there are only two options I know of, both kinda complicated maybe. First, a good welder should be able to fill the hole, except that the cast iron will probably crack. The few times I've welded cast iron it would always crack without careful pre-heating and cool down. A skilled welder can probably do it, but you may have to talk to a dozen before finding one. The weld is also nickle rather than steel, so a bit softer for threading (unless there is some new way of welding cast iron that I don't know about- which is entirely possible).

Second would be to have a machinist mill out and tap an oversized hole on the right center and put in a heli-coil to get back to the right size thread. Two big ifs- first finding a machinist willing to do a small job, not too hard, but most like this aren't in the yellow pages. Second is finding a weird sized little heli-coil. If its a "normal" screw you may be in luck, but if its like those weird 3/16-20's that hold stanely totes on, then chances are slim.

Sounds like a lotta effort for a plane, but thats your call.

Good luck with it,

John

Yes, and we don't need no stinkin knickers

>Pick up a good body and add grandpa's parts to it. As for the nicker, I do not like them. Here is a tip on how to make a better shoulder--Use a 1/8 blade in your #45 to cut the shoulder corner and then use your #85 to chew out the waste.

>I haven't used it on woodworking planes but have used it on 200+ HP water pumps to repair stripped threads it's worth a shot.

I think this would work

>There is a process known as EDM or Electric Discharge Machining. Basically, they machine using a controlled spark discharge. I have heard of this process being used often just to remove forzen/stuck/broken screws, bits, etc.

I would look up in your yellow pages for machine shops (even look for EDM) and call serveral and ask them if they or someone they know does EDM.

Hope it helps,

Thanks all for the suggestions
