Variable Speed controls?

Someone posted a while ago about the Grizzly Tool place.
I looked at the 2" X 72" belt grinder and like what I see. I was wondering if a variable speed control could be installed on such a grinder? Or would it have to be a DC motor?

I would like to have one for hobby use and I don't want to spend a lot of money for that. What do y'all think about a one speed grinder for hobby use. Could I get by with one of these to make knives and what would I need to watch for?

Thanks.

Yvsa, I've been grinding knives on a single speed grinder for 4 years now. They work fine. For a beginner thats not sure how far into knife making they want to go, I would suggest a single speed. They'll work well for you and the cost difference can allow you to get other gear you need. Down the road if you really get into it, you can buy or build a variable speed. They are better for the finishing work, so I'm in the process of building one. Take care! Michael

Yvsa,

I posted a thread about converting my Grizzly to variable speed. From what I learned, it can be done. However, it is not worth it without a DC motor. The conversion will result in early motor failure and you will not have suitable power.
I am very pleased with my machine, especially considering the price. I do not need variable speed, but would have enjoyed it had it been feasible. It is more than capable of meeting the needs of a hobbyist. In fact, Allen Blade uses it for his flat ground knives. He has made a flat grinding video (which I have), which I highly recommend for anyone considering this machine or who wants to learn to flat grind. I have already been flat grinding, but I am now able to do it much better. For instance, I never thought I would be able to grind without the use of a rest (I fabricated one since the factory piece is substandard). I found out I can do better without it, but was unwilling to try. The video has been advertised in this forum under 'Exchange/For Sale by: Makers'.
