26" bandsaw refurbishment

[Hughman]

I need to make this:

look like this:http://owwm.com/photoindex/images/8508-A.jpg

(different color, I think..) Anyone have a Silver Mfg. 26" bandsaw? where can I find modern blade guides?

[Hughman]

Here's the saga, so far:

What kind of table tilt does it have? What's the range?

How are the lower bearings and shaft?

How are the tires?

Is it a single phase motor?

[mobjack68]

rebuild the blade guides you have....they were engineered for that machine. Match the bearings/refit of the bolts and nuts w/ original sized hardware. They originals didn't last a long time accidentally...

[Hughman]

there's a handwheel/gear arrangement that needs re-bedding with babbit. I need to see another working example, or a drawing to be convinced this one will function as it should.


How are the lower bearings and shaft?looks good via Mk.I eyeball, I haven't done a calibration.


How are the tires?needs replacing


Is it a single phase motor?Yes, 2hp beast that weighs in at two big men and a little boy. Dunno if it works yet.

the lower guides are two wedges of scrap wood shoved in the frame...

[BBSebens]

very cool. good luck on that...

But I bet it will be as reliable as your Volvo when its done!

[Jim Ledger]

You should replace those wedges with some nice new ones , preferably made from Lignum Vitae.

Watch the bottom bearings. Any play in the shaft will have an effect on your ability to align the saw. They might have to be rebabbitted and the shaft cleaned up.

[nedL]

Very nice! I see you already know about the OWWM site. They should be a good help too.

Definitely register at owwm.org and put yourself at their mercy. The single most knowledgeable, helpful, downright positive group anywhere on the web.

[Paul Pless]

You gonna cage those wheels?

[Hughman]

According to the OWWM site, the wheel cage option wasn't offered till the 20's, on a saw patented in 1907. Wonder how many casualties there were?

Yeah, I'll make some up.

[PeterSibley]

You can buy a brand new bandsaw ,nearly identical to the above ,in India , new ,no cages ....no safety gear at all.:(

I wonder if the parts are interchangeable....

[Mrleft8]

I'd first look into getting "Carter" guides. They may have some that'll fit. After that, a good machinist should be able to whip up a set fairly quickly.

Carter has parts?

What I need first is parts of the trunnion mechanism for the table, or an idea how it all went together, so I can fabricate them.

Iturra sells carter guides, I think?

[Mrleft8]

http://www.carterproducts.com/product_list.asp?cat_id=12 Iturra does, but I'd go straight to the source.
Would it help if I sent you some pictures of the Oliver trunion?

Ditto on the Carter guides. They make a number of styles. One of them should be adaptable to your machine. They are well worth going to the trouble.

[PeterSibley]

I wonder if the parts are interchangeable....

Probably ,but getting things out of India can be fun ! Ask about parts for "Heavy Duty Bandsaw ",600mm wheel .

You could try QMT (Quality Machine Tools )
Ambalal Doshi Marg ,
Hamam Street
Bombay 400 023
India

[Hughman]

this is the state of things on my saw:

this is a trunnion pic from OWWM:

mine has babbit applied on the machined guides, and a broken clamping 'gibb' I don't know how this comes apart, the gear must be removed, but no pin/screw is apparent.. if it's a press fit, I'm leery of applying force

[PeterSibley]

Do you have the broken off sections ?

[PeterSibley]

I was thinking it would be easy to pin it in place ,cast iron being very easy to drill .Another (strange ? ) possibility might be to cast a repair in zinc but in place .It has a low melting point but is really quite strong and could work .A silly idea ?

[Lew Barrett]

This has the potential to be an epic thread.

[Hughman]

here's the table adjustment mechanism, with the broken part:

the broken trunnion provides the machined race for the back of the table support. the babbit -broken - was a workaround to replace the trunnion support/clamp

[Jim Ledger]

Couldn't you builf up the broken bits with Bondo and use them as patterns to have new parts cast?

[StevenBauer]

Here's an idea for the safety cage, my friend built this one for his 25" Field:

http://im1.shutterfly.com/media/47b7cc24b3127ccec29ff7c7987700000010O00AbNnLhizaOW IPbz4S/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/

Has Gingersnap been passing along my sailing invites? The season is winding down...

[PeterSibley]

That gear with the broken tooth can be built up with braze ,I've done it myself .Fill then grind to shape ,it doesn't need to be perfect .

My zinc casting idea would work too ,you'd need a couple of steel pins with slightly spread arms to hold the bit on mechanically .

[keith66]

I used to have a Wadkin 30" bandsaw, built in the early 20's it looked quite modern compared to some of the photos on here!
Health & safety equipment such as guards & brakes look slightly lacking!
Guides i sourced from another broken macnine in a scrap yard.
Broken castings can be built up with Epoxy & high density filler with a few bolts threaded in here & there, also think steel fabrication, my circular saw had its table in two pieces & the mounting lugs broken off. I fish plated the lot together & built angle brackets drilled & tapped into the frame to replace the broken lugs.
That saw ran for 15 years after that.

[PeterSibley]

Wadkin is about as good as it gets .

This is the item of my desire these days...

It's the 'floating' table clamp, without which the table falls on my toe during use...

I may try to fabricate the missing top and weld/bolt it to fit.

Or, maybe there's a busted saw somewhere... I've been told there are a lot of these made over the years.

I also need to replace the table seats, essentially pair of a bearing races

[PeterSibley]

Very simple patterns to make Hughman ,do you have cast iron foundry close by ?
Even in bronze or brass they would be cheap enough .

[Hughman]

That's my thinking. the photos are from the good folks at OWWM.com.

A fellow traveler disassembled his saw to provide these.

[Canoeyawl]

It would also be a very easy part to fabricate from solid stock. It will have to be machined anyway...
A hacksaw and a lathe (I know you have these!) will make short work of it, maybe half a day?

[ILikeRust]

Seems like you could make a pattern of wood and bondo and send it to Cattail foundry in PA for them to make you a new one.

[Bruce Hooke]

Green Foundry in Eliot, Maine does iron casting. 207-475-6669.

That's pretty damned good looking work right there.

Reverse electrolysis?

[katiedobe]

Great link on the electrolytic rust removal.
Thanks for posting it. Did it smell much when you did it?

[Hughman]

It looks really toxic! but it's harmless, a little hydrogen released. no smell.

open a window, don't makes sparks, lol
