View Full Version : Vertical Die Filer/Band Saw

Has anyone converted a vertical die filer to a band saw. I have a chance to buy a Doall vertical die grinder and would want to use it as a band saw.

Sounds to me like it's a DoAll band saw with a file band on it. If so, it's just a matter of putting a blade on it.

First let me say that I do not know the answer to your question. A couple of things I would look into are the range of SFM rates the item supports. I suppose its range could be much smaller or much slower or faster than saw rates.

The other question I would look into is whether the wheels are made the same....ie do they have a lip to control blade movement etc.

I would also think that you may or may not have guides that are set up for a saw band. What might work for a saw band might be quickly destroyed with an abraisive band.

I do think, however, that the DoAll band saw down stairs has abraisive belts listed in its big wheel-o-surface speeds guide that is attached. If you can look at or show details in pictures here of what you have, I would be happy to go downstairs and look at thier DoAll band saw for comparison.

I could understand converting a die filer to a hacksaw, but a "bandsaw"is a completely different design .I would like to see pics of the design you have in mind Alistair

Allistair-- DoAll made what I think they actually called a band-filer that really just looks like a vertical band saw but took abraisive belts. The DoAll band saw down stairs (I just went and looked) lists one of these filing bands for use with various metals on its big round speed and feed wheel (a round guide for recommendations for cutting various materials). On this wheel you dial the material and it recommends the number of teeth for the band and the SFM rate which you can read on another dial as the unit is variable speed.

It is not a die filer in the typical design that holds die files and moves them up and down in a reciprocal fashion.

There really was (is?) a die filer that has a continuous band with short file sections riveted on just one end to the carrier band. At the working section they present a continous file but can "fan" out as they go around the wheels. The guides are different to provide a channel for the file sections and a backer like a belt sander, but I should thing that stuff could be changed and the fpm should be similar to the requirements for a saw band. I remember thinking they seemed to travel fairly slowly, but I know that's all relative.

Allistair-- if someone said "die filer" I would think more of something like you have, although perhaps less colorful:D

That seems to be a pretty nice machine...and a nice find. I am guessing that there were not that many die filers around originally...and sadly that most of them have been melted by now.

You are exactly right! From across a room you would swear it is a vertical band saw. Only when you get close do you see that it has a band with file sections riveted to the band. SFPM is 50-300.

I changed a "continental band filer" to a band saw. The blade guides have to be changed. I also changed the motor from 1750 to 3450 to double the speed. At about 700fpm it still slow for a lot of material.

There is also a "chain filer". I have one made by Grob. It sort of looks like a bandsaw but would be a huge amount of work to convert. I ran out of room in my shop, its been tarped in the yard for a few months. I think the scrapie is going to get it.
