Re: Milling attachment for mini lathe
You can add plate for more work aera too. It limit on stork to 2" x 3" . This should do almost everything needed for milling. When had Bridgeport with 48" table most was done 5"x5" in rare I need to

Re: Adjusting Gears Just Right
Like the pdf how complex it can be . The way I found is paper between the gears on setup. It fast and easy. Most gears like a gap of 0.005" [0.12mm] . You adjust the paper layers till gears run quite.

Re: Adjusting Gears Just Right
Here's that gear problem picture. Adding an M8 washer on the Stud moved Gear B off contacting the Left Bracket and gears engage more - is that a reasonable solution?

Re: Adjusting Gears Just Right
I read somewhere (don't remember) that if you use a slip of thin paper (newsprint works well) between the gears, that is the clearance you need. You crush the paper as you mesh the gears and tighten.

Re: Adjusting Gears Just Right
I should have noted - I have just upgraded my LMS 7x12 with a 7x16 Bed Extension and find the gnashing is actually Gear B just barely contacting behind Gear D on it's back edge. The gears have ~2/3

Re: Erratic spindle speed
Tom, Is the F/O/R switch a DPDT (for just switching the polarity to the DC motor) or are there additional poles on that switch? Some of the mini lathes have an additional? pole on the F/O/R switch

Re: Adjusting Gears Just Right
Yeah, probably too tight. The plastic gears also tend to have tight and loose spots. When I was using them I set like I did back when I raced RC and slot cars. Use some news print. Put two thicknesses

Re: Erratic spindle speed
Easy to check continuity on the switch with a VOM¡or maybe a wire got disconnected while you were fixing the fuse.

It made in China. They do there designing by just copying a good product. It cost $59.00 free shipping. It part of my down sizing It nice to have some type mill. The next part is mounting to lathe.

Re: Erratic spindle speed
Thanks everyone for you response. I cleaned the pot with alcohol and while I was inside found that the fuse holder had a loose wire. Put everything back together and the erratic RPM problem is solved
