I just finished up a new skinning knife for a customer going to Colorado in December for an elk hunt. I have to sharpen it and make a sheath

I have just recently cleaned out an old smokehouse that my grandfathers grandfather built in the early 1900's it is 10x12. It is the nicest shop I have had my first shop was a roof built off the back of the smoke house with a work bench. My second shop was a pop up camper converted to a shop it...

Well said , I think that grinding is the key to prep for hand sanding. I know I have done a lot of hand sanding at times because I didnt do a good job getting the scratches out on the grinder

So an 1800 rpm with vfd and 6" wheel will get you below 800 then

So how slow can you go with a vfd?

So some of you say you use a 3600 rpm motor. from what I have read you lose power when your at less than 3600 rpm with a 3600 motor but with a 1800 you will have full power from 1800 all the way to 3600. Can yall let me know which is most desirable? I can get the package either way with a $40.00...

Thank you guys for all the help. I know the variable speed is going to pay off. the main reason i wanted to know about drive wheel size was to make sure i had the speed there when i need it. It will be nice to dial it back when doing more finish work too.

Ok thanks I was thinking the same thing

So should i go with a 4" 6" or 8" drive wheel ? Can someone tell me what the max belt speed would be with each. I currently have a 1750 rpm motor and a 6" wheel with my single speed set up. I would like to know what the difference would be also with the vfd I slow can I go?

Yeah i think im going to build a pad off the back of the tooling arm support to bolt it to

gotcha thanks

Oh I can run 2 motors off of one vfd too right

I have two 240 outlets already for both my grinders. :) The vfd and motor combo are on sale 5% off right now too.

I think this is the VFD and motor I'm gonna go with hard to beat the price. https://dealerselectric.com/Package-NAT2-18-56-and-L510-202-H1-U.asp

Thanks again for all the info guys. I now have to decide which to get and what options I want. It will be a few months before I actually tackle this as I ned to get the Christmas orders I have done before I shut down equipment lol. I assume the VFD supply places sell the speed knobs correct?

So if I mount it somewhere up above the grinder and off to the side it should be fine with just an A/C filter to keep the dust out.

thanks this is helpful also makes it sound less intimidating

Scott , do I have to program the vfd? What are the program options i just assumed it was turn it on and twist the knob ?

Yea I only work around 3-5 hrs a day maybe longer on weekends. I am leaning toward this one based on cost.

Thanks for all the info keep it coming. I do have a friend who is an electrician so worst case he could wire it for me. I appreciate the link to the teco vfd and the chinese one. I just want to make sure i get something im not going to have to scott.livesey have you used these drives and motors...
