I just picked up one of these tool post grinders from LMS.
I have a need for a TPG/drilling head and since I am knee deep with my other projects I did not want to bother with a 100% scratch build. I have already tried the die grinder and dremel thing years ago on the lathe with poor results.
Oldtiffie also has this TPG and I had asked him what his thoughts were.
So having owned a number of import machines and tools I pretty much know what to expect now. I figured it was a assembled kit like most of the cheap import machines.
IMO, yes it is a kit. I had to turn off .1" on the driven pulley to keep proper belt alignment right off the bat. The supplied wheel needed quite a bit of dressing.
It uses simple deep groove bearings and the spindle while made accurate is "rough".
The motor appears to be the same as used in a 7x mini lathe and a uses a similar type of controller.
The motor runs very smooth though as does the belt drive system. 7000rpm is the limit but it would be very easy to make new pulleys to increase the speed some.
The little drill chuck is not to bad. It has about .00125" runout and can get a drill bit to run about as good.
So I installed it on my SB9 , dressed the wheel and tried it out.
It actually works very good with little vibration. Plenty of power and left a good finish.
I will probably modify it a bit with better bearings and possibly make a new spindle with a er11 collet head instead of the tapered end for a 6mm drill chuck.
