Viel conversion

[Ordener]

Hey guys!
I’m looking to install a 12 volt Penn State motor on my Viel 1X42. I would prefer to use my 6” drive wheel, and bore it out to fit the new motor. Does anyone offer an adapter plate that I can simply bolt on to my Viel frame, and still utilize my 6” pulley? Do they make a 15mm drill bit, or an imperial size that matches? 
Thanks!

Garry,

Yes, metric drill bits are available, as are metric reamers.  McMaster-Carr has both.

15mm drill bit (scroll down in the window that comes up)  $23.49

15mm reamer (same deal with scrolling) $44.42

Drill bits tend to cut oversized, sometimes by a couple thousandths.  Best way to minimize cutting oversized is to drill it out first with the closest undersized inch drill (37/64" in this case, 0.781"). 

A better option is to ream it, but that comes at a slightly higher cost.  Again, best way and about the only way is to drill it first with the closest undersized drill.  In the case of reamers, they have a limited range of how much they can cut/remove, so you pretty much have to get quite close to the finished size, which improves the reamer cutting to size.

You are quite welcome.  I forgot to mention, that if/when reaming, use a fairly low speed.  If using a belt driven drill press, likely the lowest speed you can get.  That size of hole, I would not be using high speed for the drilling either, but probably not as slow as for reaming. 

Use cutting lubricant for both.

Garry,

Unless you happen to have machinist skills and gear, I think it is not cost or result effective to try drilling and reaming yourself. I would suggest (both) getting an estimate from a local machine shop to bore the drive wheel out to 15mm and contacting Steve. (With a local machine shop, take the motor with you to get a good fit and make a flat spot to secure the drive wheel.)

I used the motor bracket which comes with the Penn State motor to mount the motor with six inch drive wheel. It worked fine, but is not just plug and play. 

The bracket from sharpeningmadeeasy is primarily designed for the smaller drive wheel, however, it can be repositioned to work with the six inch drive wheel. I chose to use the smaller drive wheel because it is mathematically better at low speed. From a practical basis, either size should work fine.

Please check your messages.
