Dowels

Hi Cal.The dowels did the same thing.I tried a tungsten brill bit ,but they spun around I tried the epoxy bit no luck.The dowel holes are 12mm deep with broken dowel in them.12 mm depth should be enough to hold in place with 4 bolts holding lead screw nut holder as well.i have the the high and low selector working with ease.When machine arrieved H-N-L was completly jamed.The machine must have worked only in one gear..Every thing noe runs freely.Regards Phil

The saddle here is the same way, but I'm still determined to get the broken dowels out. A couple more things to try: use a center punch to stake the dowel to the bore so that it can be drilled out or use Loc-Tite (medium strength) for the same purpose.

Did you locate new bearings for your spindle, etc.?

Bearings

I have replaced spindle bearings only.Bearings did not seem to bad.IF I had replaced all bearings it would have cost me nearly as much as I paid for machine.The average price for angle thrust was £35 compared to £12 for deep grove.Fitting the angle bearing is quite a job as they pop apart very easy.I got them fitted and all seems ok.Seal were a problem as i could get ID ,but had to make up ring for OD.The bevel gears blued off fine.Just had to take off high spots, as usual I had blue up my nose in my ears and on the telephone. I would say i`m getting 90% engagement,shims did not need to be changed,there were layers as you said.The large bevel runs in bath of oil,this will have to be checked often.Money plays a large part in project as enconomy is not to great.Regards Phil
 
Hi Phil,

I haven't checked your PhotoBucket page in a while. It looks like you’re making good progress!

The internal parts for the table feed mechanism sure cleaned up well. Did you polish the shafts for the bevel gears?

BTW, I think the sleeve/spacer on the short bevel gear shaft (on the right) belongs on the other end, next to the worm gear.

Did you take apart the worm gear?
