Bandsaw Brazing Repair

[@samcoote9653]

Love the way you narrate as always Ade, it's like the Attenborough of machining! very cool tip thanks so much :)

[@AdeSwash]

Glad you enjoyed it, Thanks Sam

[@jmtx.]

Awesome! Very nice systematic way of repairing the blades.

[@AdeSwash]

Thanks! 👍

[@wadestewart9891]

Very good ,never had much luck silver brazing my blades might give it another go. Thanks for the inspiration

[@robertoswalt319]

I had a blade break a few days ago. I hated the idea of throwing it away. I may have to give this a try sometime. Thanks for sharing this with us.

[@AdeSwash]

Go for it!

[@eddieholmes5763]

Great stuff as always. Can't see me ever having to do this, but as a beginner it's been a good watch and I've learned something new. Cheers!

[@andrewdolinskiatcarpathian]

What a super idea, brilliantly executed. Well done 👏👏👍😀

[@donaldnaymon3270]

Great video. Good to save usable blades. Thank you for sharing.

[@andypandy9931]

I remember vertical bandsaws that had a welding attachment a grinder on the back for this purpose.

[@ellieprice3396]

Thanks for a great video. I made a similar jig but found it hard to find silver solder flat strip. Your lifting screw solves that problem by using a piece of round solder instead.

[@AdeSwash]

Thanks Ellie, yes it seems to work well, thanks for the comment

[@rossgee1091]

If you can't find silver solder shim, just belt the end of a round bit with a hammer and voila! you now have shim!

Hi Ade. Truly terrific vid. You're very polished at it now. Glad to hear the repaired bands are holding up, cus what I was thinking during the vid was about the temper of the steel at the heated spot. You don't dunk it, so it will be annealed, which is probably the best way. I imagine the teeth will wear very quickly at that point but it's such a small area as not to matter. Altogether GREAT I'd say. :) Great arrangement with your jigs for clamping, grinding etc..

[@AdeSwash]

Thanks John, yes as you say it is already annealed from the brazing process, not too woried about re-hardening and then tempering back, a few teeth skipped on the cut dosen't seem to make much difference overall

[@CreaseysWorkshop]

Fantastic. I've tried this and failed. Like all the other commenters I will have to try again!

[@AdeSwash]

You can do it!

[@upthereds4939]

Brilliant job mate

[@AdeSwash]

Cheers :)

[@davidallison1732]

Would a 15 degree chamfer on the blade ends provide a bigger overlap and consequently stronger joint?

[@AdeSwash]

Hi David, yes a shallower angle will work, the more overlap the better I suppose

[@therealchayd]

I've got that exact machine (brought at scrap price from retired locksmith), came with a roll of blade, and no idea of how to join it, until now! Thanks!

[@ronsonnenberg6325]

looks good man,got to try it your way

[@zvonibab]

Did good job there Ade, just aneling

[@zvonibab]

It will be too brittle other way! Cheers

[@KCBhandy]

A nice upgrade to the jig originally shown on Toms Techniques

[@AdeSwash]

Thanks 👍 Who is Tom? Link?

[@robmurg]

Now I've got 'The Ballad of John Henry' going round in my head!

[@Machine_NZ]

Awesome repairs Ade. How have the blades held up in use?. Cheers Kevin

[@AdeSwash]

Hi Kevin, no problems so far, been using one for about a month without any problems, the one in the vid is a repaired one

[@rickrick1867]

I find having a good blade is the most important thing with a horizontal bandsaw . having got everything perfectly set up I can cut 20 thou slices with a good M 2 bimmetal blade . the difference is massive . I would like to try Brazing new blades - As I am in England what is a good flux / solder combination please ? I donnt seem to brake many now , a worn out blade is not going to cut straight .

[@AdeSwash]

Hi Rick, I used Silver-flo 30 with easyflow powder flux

[@birgittamm159]

It's a very good tuorial, Thanks!

[@grahameblankley3813]

Very good video, however now I've mastered parting off on the lathe with blades I've made from a good quality used circular saw blade, recently I parted off at 800 rpm plenty of lube 25mm dia, so I find hacksaw almost redundant, 🇬🇧 Coventry.

[@AdeSwash]

Thanks for the comment Gray, I also part-off when it is appropriate, but I also cut a lot of flat and plate stock, can't do that on a lathe unfortunately. Rgrds. Ade

[@tomshahriari6602]

Does the blade need annealing before use?

[@AdeSwash]

I didnt quench the blade so it will be annealed over the short area of the join, to the teeth in that spot will wear, but the blade just skips over

[@dfross87]

Does the newly repaired blade beat the worn out old one? More importantly, does it beat an Ade powered hacksaw?

[@AdeSwash]

Hi dfross87, the new (repaired) blade works like new, as for the hacksaw, it stay stay in the drawer where it belongs ;) Regards, Ade

[@MonstroLab]

This is great! I may mill the back side of an old aluminum heat sync i have for the clamping jig, its about the same size. I lucked out today and bought the last two bands off the shelf they came to my truck like a drive-thru. Wish we had plethoras of Myford lathes over here like in the U.K., Id own one.

[@AdeSwash]

Sounds great!

[@oldschoolengineer58]

great content, neat job, thanks for sharing

[@AdeSwash]

Thanks for watching!

[@marianainsworth9327]

Very nice, thank you

[@delstone1919]

Nice one ! I always considered welding was the answer to joining/repairing bandsaw blades, but I'll be trying your method neext time I break one. Cheers Ade.

[@AdeSwash]

They seem to be holding out ok Derrick, had the last blade on for about a month, possibly longer and it hasnt failed yet, cutting good and strong. Regards. Ade

[@TheJimtodd]

I wish I could saw as straight as you by hand

[@couldbanyone9318]

Another gem, keep 'em coming. Great explanation, 'the David Attenborough of machining' 👍🤣🤣🤣🤣 lmao

[@AdeSwash]

Glad you enjoyed it :)

[@GTRliffe]

straight after brazing when still hot, some shot peening with a sharp hammer would also help in strength

[@RustyInventions-wz6ir]

My stile. I love it

[@AdeSwash]

Cheers Rusty! :)

[@VAARRR1]

Hi, it is better to use welding

[@AdeSwash]

I dont have tig welding equipment, this works well, and is what most model engineers have at their disposal. Rgds. Ade
