First time using my 1” boring bar

[Janderso]

That spider is a cool tool I did'nt know I needed! lol I have a good donor part to use as a base from a failed first attempt at a collet closer. I had too much work in it to throw it out. Now I know what to do with it! Thanks.

Pretty easy too. I had to tear down the four jaw after i finished. I had a nice big pile of C’s and 6’s.

Spiders are nice to have. I made one for my lathe. Not hard to do.

Jeff I used to have the same problem measuring ID. I watched more videos than you can shake a stick at on measuring ID's. Then I noticed in one video where the guy used his thumb to keep the telescoping gage in place as he moved the gage. Since I started doing this I now get consistent ID measurements. Having a micrometer stand also helps. Mine is a mag base with a clamp to hold the micrometer.

Thank for the tip.

I had the same problem with chips from boring the spider filling the 4 jaw chuck and getting into the scroll of the combination chuck. I solved it with a piece of ABS pipe cut to fit the inside bore of the chuck. See pictures below:







Chips in the chuck problem solved.
