Have any of you ever changed the drive belt? I have mine pretty much disassembled and still cannot figure out how to get the belt onto the pulley. What am I missing??

Also, is anyone reproducing the leather cups for the transverse drive and the oil pump plunger??

I have not done it, but when I'm faced with it I would explore buying one of those V belts that is made in individual "links". Yes they probably cost a bit more but worth considering
Pump cup. I have formed leather myself. I soak it in water until it is good and wet. I then make a "male and female " mold and press/clamp the leather into it and let dry. Put the smooth side out in the mold. I have used this method!!

Les is correct on the link belt idea. The brand I used on my lathe is Fenner. The belts consist of nothing more than multiple links of the same shape, and they are just twisted aside to make the join. The material is as tough as old boots. In 15 years I have not even had my lathe belt off to take out a link to adjust the tension.

The pulley unscrews from the drive tube and then the pulley can be dropped down to change the belt.
I'll check and see if I have an exploded view of the drive head.

Randy, got home to late to call.

Your number was not on my phone, and it should have been.

Call anytime now.

Herm.

My parts book shows the complete breakdown and I can post a picture of it or send it to anyone interested, but the thread connecting the pulley to the drive tube is left hand. If you pull the feed cylinders all the way out, there is a keyway in the drive tube that you can use to prevent rotation of the tube and then grab the bottom of the pulley and unscrew it. My records show that the belt is a 70" A section belt.

Sorry I forgot today. When I got mine I was missing the facing cutter holder, which I managed to figure out and make. What might you be missing?
I was busy machining intake manifold parts

The TA thrust facing attachment that I have is quite sophisticated/ complex piece of machinery. It permits the operator to move the cutter radially as it spins. It has a hand knob sticking out sideways that I turn. It is connected through a bearing to a angular tooth gear rack which engages with the cutter holder. If you don't have most of it, I believe it would be a fairly interesting project to build one from scratch. Perhaps within your abilities

Les, I believe I have most of the pieces for a thrust facing attachment for my TA 14 but can't figure out what I'm missing. If you could post a picture I would be grateful. Love your 5 main block project.

Bill
