Re: Change from 316 SS to 410 SS

Well seems to me your customer will have to live with tolerances and finish that you can obtain with the 410. If he doesn't like the results show him the door !

Re: Little Machine Shop 5100 lathe - opinions?

Research the lathe for vari-speed issues. Seems to me those [and mills using similar controls ] are somewhat failure prone. Only thing I see to recommend it is price.

Re: Best endmill for slotting Stainless.

You may be recutting chips after your first pass. Use a 2 flute mill preferably carbide and use a vacuum or air to remove chips ahead of the mill on second and on cuts.Recutting chips may be the cause for poor finish on the side walls.

Light cuts in AL should do it. I have a similar v block ,wider, plus angle table,and sine table. This machi...

Re: milling a wedge

Well first determine the angle needed. Do you have a set of angle blocks? If not use the adjustable v block to find the angle needed. Use that V block with a over length piece of material so you have area to clamp to. Mill the angle needed and saw off the excess material .Even if you had a tilting t...

Re: Clausing 5900 Intermediate Pulley breakdown

You might try posting in the Antique section of Practical Machinist forum with your question . At one time there was a gent. that was knowledgeably on these lathes but has not been on the board for close to 2 years. at one time there was a Yahoo group for Clausing,since closed.

And if you call Clausing with the the model and serial number they will send you a PDF manual for your exact lathe FREE !! Be VERY careful as most parts are available albeit eye wateringly expensive.

Re: Another dumb question...

The slightly different bushing is the one that supports the arbor in the overarm support. And yes arbors usually have keyways,but with the light load imposed by the gear cutter I would think if you firmly tighten the arbor nut you should be OK. R-8 with a keyway ,look on eBay for one made for use wi...

Re: Menards Milling & Drilling Machine DL300-150

OH !!! With NP317's pictures with the head hung off the side like it is for the tilt that adds a new definition to the term flexible flyer !!! If it had the X-Y table would still be better than nothing ,just not by much.

NP317 I can only agree with Harold about determination !!!!
