Highpower, the bearing puller / installer set for the mini-lathe was from Micro-Mark?

Did it come with information that might allow making a copy? Drawings? Pictures?

Yes it is available (for now) from Micro Mark. https://www.micromark.com/Metal-Gear-Set...g-Machines

If you click on the link you can download a copy of the instructions from there. No drawings or dimensions given that I can tell - but I just recently ordered mine and haven't received it as of yet. I could measure everything once I get it I suppose. The last time I had my mini-lathe apart I was able to use my shop press and various pieces of pipe to get it done.

The bearing puller / installer set arrived. Lots of Chinese grease to clean off before I could measure things but I got it done. The only CAD I can do is cartoon aided drawings... so all I can give you are dimensions I'm afraid.

Count me in for a copy as well Ed if you do.

I got the angular contact bearings I ordered from the UK too. The package sat at my local FedEx shipping center for 3 days without being delivered.
I finally figured out it had the wrong delivery address on the FedEx paperwork. Wrong house number and wrong street name. The shipping info was all correct on the bearings company's paperwork, but whomever printed the shipping label got it wrong.

I'm just glad I caught the error before they shipped them back to Great Britain.

The bearings from Ireland finally left the seller's place on the 18th. I emailed them on the 17th requesting the status of my order because I had heard nothing from them such as an order confirmation or a shipping estimate. Their excuse was a mix-up with the courier. Anyway, they're sitting in London at the airport with no delivery date estimate yet from FedEx.

I'll work on the drawings and post them once I finish them.

Got some unexpected good news today. Quality Bearings asked me for a review so I gave them one and included the above info.

Never asked for a refund but they sent one anyway for the full shipping costs.  

I should be getting the all-metal hi/low gears from China today but I'm not holding my breath on that happening given my history with the USPS.

Hopefully the tide is finally turning for our local post office. (Knock wood.) We haven't seen our former mail carrier for awhile now and we seem to be getting ALL of our mail delivered now that we have a different carrier on our route. The gears actually got delivered and on the day they were scheduled to be! First time in YEARS!  

The machining is much better than I expected it to be. Just a little touch up of the sharp edges with a needle file and I think they will be good to go. They have a few minor dings from banging together in the plastic bag they were loosely tossed into, but not bad. Still better than I thought they would be.

eBay

It looks like the seller I got them from is out of stock now, but lots of listings for them on eBay, Alliexpress etc.
