My TA will only give me maybe 8" plus it gave me fits last time I tried to use it. I wasted hours trying to figure out why I was getting so much binding while using it. I suppose it would have performed better with only a 1* angle. I read some posts about using the compound in several steps and wanted to try it. It did take a lot of time and care to blent the cuts as it progressed. I can't imagine doing this without the collet chuck.
I've noticed some binding can be caused by the way clamp trying to lift or push the end of the taper attachment up or down. 3 things that might help are: a good cleaning, a longer rod between the slide and the way clamp (reduced misalignment forces) and spherical washers anywhere the rod between the two threads into something.
But yeah, I'm very impressed you were able to machine something that slender. I was making a part the other day about 0.2" diameter and 7" long and had to grind it due to deflection in the middle.

Manila rope can wear out (self-abrasion) and mildew or rot. from the inside out, so it may appear to be in much better shape than it actually is:
Manila rope is a natural fiber product which has been in use for thousands of years. It's no longer the strongest, but still a very popular decorative rope.

I've gotcha. We've definitely had some trouble with ours too. The biggest issue is that it's a leadscrew pusher, and if your leadscrew is worn at all (it is) then there is lost motion in there due to the tool pressure and taper attachment both trying to move the tool in the same direction. It's a fundamentally flawed design IMO. I've seen some measures to combat it like springs on a MAZAK, but I think the South Bend design with the clamp is much better. Dad modified ours to be like that but he only did a so-so job.

I've spent so much time on it. Cleaning, taken apart etc. I'd like to understand more about the bar issue you speak of your saying the way cslmp and bar should be allowed to move without affecting the TA? What's odd is the TA was hardly ever used and doesn't show the smallest amount of wear. I guess it is the other worn parts that cause the issue. Mine actually makes the carriage bind to the point that it lifts the back of the carriage.Last edited by challenger; 05-15-2020, 08:21 AM.

Not made by me. But my SO designed and had this play house built for our kids, put it up this week. Funny thing is, the guys who built it, one is an economist and the other an engineer with well paying day jobs, they just do this for fun and little extra money.
Still needs to be painted both inside and out.

wow! That'd be a nice one bedroom home in a British city
All I did yesterday was fix a bullseye chip in the windscreen of my car. Second chip I've fixed with a RainX kit and amazingly the resin is still good some 4 years after I first used it. Pretty magical stuff to use. Fix isn't perfect, you can find it if you know where to look, but way better than before.

[QUOTE=challenger;n1876964]Today I removed another bee hive from a house.
What a mess. I hope you got it all cleaned up. I could imagine ants replacing the bees.
