Tool post grinder
Spotted this :
LittleMachineShop.com - Tool Post Grinder (220VAC)
I like the variable speed, but the motor looks a little small and underpwered . There is another smaller one there that looks like it has a sewing machine motor on it .

thanks
Yes I spotted it ... very interesting . I posted a link to your plans on the Southbend Yahoo group .. 1930's technology still works
Are you making that particular Grinder yourself ??? Where would you source a motor like that ?
I did a TAFE lathe course last year ..I recomend it , but may be to far for you ....

HI,
Since seeing those Tool Post Grinder Plans I have done more Research and have decided to make a 1/3hp (250watt) Tool Post Grinder. I am looking at using a Quorn Motor Quorn Mk 1 - 0.18Kw 240v 2800rpm Mark 1 motor - Hobby Mechanics or I might see what Royce Cross has available. Although the Quorn Motors are listed as 180 Watt, I bought one motor of them late last to build a Quorn and it was 250 watt.
Since I am going to Build a bigger Tool Post Grinder I will be designing something Myself - No doubt I will use ideas from existing Designs.All The Best steran50 Stewart

Mike I was considering that TPG myself and from what I heard it was "ok". Like a lot of Chinese tools like this, a bit of a "kit" when it's unpacked, but a good base on which to improve. Getting it out from the US however isn't cheap. While I was poised to buy it, in the end I've decided not to get a TPG and will probably make other arrangements when I need to do work like this.
I do like the way a drill chuck can be fitted for cross drilling in the lathe. I have another fixture to hold a Proxxon drill, it works extremely well but I am very limited with the size drill bits I can chuck in it. This TPG would enable a much larger drill chuck to be used.

I don't know if you blokes have looked at some of the old posts related to TPG's but here is one about my Dumore 44 and the fun and games involved in trying to acheive an acceptable finish. https://www.woodworkforums.com/f65/to...51/index2.html It may be of some interest.
If do end up buying or making your own, make sure everything is covered up when you use it. The destructive grit goes everywhere.

LMS had a clearance on the smaller grinders a few months back, I think they where $80. The people that bought them seemed happy with them.

I read your posts .. I recall seeing a home made TPG a chap in the UK had made . After extensive research and work, he found the best results from a grinder he built with plain bushes rather than ball races .. he tried all types of designs ..but the plain bushes beat everything

Yes
YES thats the one ....
I wondered about using a universal motor from a domestic sewing machine - they will run from both AC and DC , unusual motors and they lend themselves to easy speed control .

The problem is , not enough OOMPH . Maybe two working together would work . OP shops are full of old sewing machines with those motors
