I'm not aware of any attachments to turn a handheld grinder into a belt grinder, if you can get access to a mill and lathe might want to look at the Pipe-Max for some inspiration (I've got one and its awesome but I don't think it would be that hard to make your own) http://www.csunitec.com/metal-surface-finishing/pipe-grinding-blending-and-polishing

 

Thanks for the suggestion. I have a pipe polisher and making your own for me unfortunately is out of the question.

 

You know I spent a lot of time looking for a used Metabo burnisher a while back for a reasonable price. Couldn't find one so I spent big bucks buying a new one. Turns out the only thing that separates a burnisher from a grinder is a little adapter that threads onto the spindle. Burnisher motor eventually burnt out, so I just took the adapter and installed it on a variable speed grinder. Grinders are so mass produced that there are soooo many different applications where they just make the adapters to fit a grinder body. I don't know the setup of the Dynafile, but it may be as simple as unscrewing something from the spindle and threading it onto another one of your choice. You could look at the diagram at www.eReplacementparts.com and see how it goes together. Might be able to just order the replacement parts you need to make the bandfile.

 

This is the exact thinking I had when making this particular post. I looked for something but just could not find it that's why asked the communities help. Thank you for expressing my thoughts better than I could.

 

Hf used to sell one. However, the now sell a band file and no longer carry the conversion kit. The hf band file works, the rollers and guides wear and limited on attachments. I have a dynafile with several attachments and makita both purchased second hand.

 

I looked at the harbor freight model in person. Without offending anybody it is so cheaply made not to mention the lack of attachments that it's not even a consideration for me. But I do appreciate your efforts in helping.

 

What issues are you having with the one you posted ??? I have that same setup for over two years. I use both the 1/4'' and 1/2'' belts. It's used almost daily with no problems. I just got a whole bunch of 3 M belts for it from the FABTECH show. It really served me well .

 

I have that set up and it's limiting first in the actual motor body. And secondly most important is it doesn't have variable speed capabilities. I've read some of your earlier posts where you claim to have Metabo products. Since you're familiar with Metabo ( I don't know if you have any experience with their variable speed line) maybe you could understand how been able to adapt the dynafile to a Metabo grinder body would be extremely beneficial and would result in a much more superior product.

Don't get me wrong I am not trashing the Dynafile. I use one when it's necessary. I am just looking for more capabilities from an existing solution.

 

@ Weld_ - the simple answer to your request is "no".

We run a pneumatic Dynafile II. Excellent condition, $140 via CL and equipped with hose/swivel as shown. The housing had a slight crack that did not/not effect performance. However, we contacted Dynabrade and ordered a new housing for $40. Then, replaced several o-rings and springs for an additional $25 to fresh'n the nip. Now, she runs like Speed Racer's Mk V on surface finishing DOM tubing and other material removal apps. Never experienced any 'shortcomings' you inferred.

Dynabrade's customer service is best in class.

 

Dynabrade for the most part is very good with their customer service. I am not knocking the company just trying to expand the capabilities of the current product offering. I appreciate your suggestion but you are comparing apples and oranges I need something with a cord not a pneumatic solution. But as always I appreciate you chiming in trying to help.

 

To everyone responding and viewing this post I would like to wish a happy Thanksgiving.

 

I have an electric Dynafile and it's quite handy. I still prefer the pneumatic Dynafile with the 24" belts but you don't always have the option of dragging an air compressor with you everywhere you go lol.

I've seen some of the bolt on jobs for angle grinders but they didn't look as well built as the purpose specific stuff. Maybe something is out there for metabo machines... The connection point area is different than other units because of their guard design. On the newer ones anyways. That may be where the difficulty lies in a retrofit effort...

Good luck with it either way. If the electric Dynafile was vari speed it would be great lol.

 

That is the point I am trying to get it to variable speed status on a better motor.

 

My Metabo burnisher is vari speed, but after seeing CS Unitec's rat tail offering at Fabtech, I wish I would have waited. I got a good deal on mine tho and bought it as a kit with the metal box and everything. Unitech's machine is over $700 retail and I dunno if you get anything with it.

The purple machine Mick has is made by the same company, only marketed under a different name in Europe and Oz.
