Not to hijack Timber's thread but to answer Md's saw question, the little HF saws can be made to work just fine with a little tinkering. First, dump the supplied gear oil and clean the sump of any casting sand/chips you might find. Second, replace the blade with a good bimetal blade. Third, make any needed blade bearing adjustments. Also, make a decent sturdy stand for the saw. These little saws can then provide good service at a very low cost.

Multiply that 35 mark by 9 = 315 add 5 * 9 more marks voila, 360.

It is a Euro thing, in Gradians !

of course it will hit or miss any setting you want..

Looks like you are right,
adding to that, the tool holder can be set in 40 different positions around the post, each mark/div on the dial indicates one of the 40 positions.
360 ÷ 40 = 9º

Educate me though, isnt the postion selected, just dependant on the adjacent shoulder you want to form ? with exception of some tool bits I am not familiar with yet. Uhm, which is all of them

Yes, for your finish shoulder.
For roughing it is not uncommon to rotate the tool CW about 5º so the tool tip does not lead into the cut, if its a rough scaly hot-rolled steel the tip takes less pounding.

You will find out when you need a sharp shoulder that rotating the tool CCW about 9º will help position the tool when you, face the shoulder cutting back outward.

Being able to rotate the tool without unbolting the post is a convenience, and 6º would have been better as that is what I grind most of my tools at.

What a nice machine ... never heard a bad word about Matt or his PM machines

The extra $$ for the 1.500" spindle bore is money well spent. Wide speed range too, from 50-1800 rpm with electronic speed control.

Let's see some chips ...

I never understood how the idiots came up with Grads for a circle. That is just
plain STUPID. It's a wonder they didn't divide it into 1000 and be consistent.

So... where would a feller go to look at more of these machines? I've never heard of the brand, but that 1.5" spindle got me interested quick. Link?

I got lucky on getting this lathe.

All of thier Lathes were pre-ordered.

I called on the very day, that they found out a customer had health issues and would not be taking the Lathe.

I dont know, maybe they still have some.

Double non-hijack: It was a happy day when I sold my HF saw. Never cut straight, even with a new blade. Had to really tweak the adjustment bearings to get the blade to stay on. My only regret was not finding these problems while it was still under warranty. My Turn-pro from Enco has been a good saw and cuts square to within a degree. Lubrication via pump makes all the difference.

I'd venture to say that the lack of easily and accuratly adjustable guide bearings is the biggest drawback to good cuts.
