Nice work! In the past I've pressed ball bearings (with plenty lube) through tubing I've bent and it will generally take the kinks out

Good design/result in the end Alan. I have an App controlled plug-in timer in the power feed to the Compressor that turns off at a set time each afternoon/night regardless of the Power State but despite that, the hissing throughout the day is annoying, so such testing is a great idea.

I just turn the compressed of ! Kit from up north

This are insert for a slitting saw not tangential ... There are not made go cut on the side flank

I'm working on a rebuild of one of these at the moment. They are a bit of a nightmare in many ways, mainly the x-axis flat linear bearings and dovetail roller shaft assembly that auto compensates for wear. It's the strangest thing I've come accross in a long time. I really appreciate your videos, they have been incredibly helpful. Mine had been apart and been put back together rather poorly. The bearings for the auto adjusting dovetail rollers were put in different configurations on each side. My machine used 6202 deep groove ball bearings and 7202 angular contact ball bearings on the dovetail roller shafts. I noticed you placed the sheilded one side 6202 bearing on the bottom and the 7202 on top. Using a sheilded besring on the botton initially made the most sense. It's how I assembled it the first time. I put an indicator on the dovetail roller shaft and it could move axially with very little pressure. From what I can tell the sheiled 6202 bearing should be placed in the top bearing position. There's no way to preload the upper bearing so the 7202 angular contact bearing can seperate and allow the shaft to move. The lower bearing is always pre-loaded because of the captured spring and cir-clip on the dovetail roller shaft. The bottom position is suited for the 7202 angular contact bearing as it must be preloaded to work. I have it reassembled with the 6202vin the top position and 7202 in the correct orientation installed in the lower position. The shaft shows almost no axial movement now and the 7202 angular contact ball bearing has the preload it needs to work properly. I just thought I'd mention in case you were getting rough x-axis travel. You could find the table lifting if you had overhung table loads towards back of machine. My machine may not even have the original bearing types so it may bot be an issue for you. I ended up going with new bearings. The top heavy steel washer didn't keep out all the grinding dust and the bearings were in very rough shape. I used 6202-2rs on the top with standard rubber seals and 7202 non-contact rubber seals on the bottom. I saw no reason not to use sealed bearings. The non contact lowers spin verly freely while the standard rubber seals on the 6202 offer minimal drag when spun by hand. The table moves very freely when its all assembled. It didn't make sense to go back to the original open bearing design given their condition. Thank you for posting the videos, you saved me a lot of time and frustration. Hopefully mine will work as well as yours when done!

Nice! Going to do this!

A good idea. I only use 4-jaw chucks on my rotary table.

Nice explanation and many thanks for taking the time to shoot, edit, and upload this content for our edification. Thank you sir

Absolutely brilliant video

good result Alan,, is that your idea?? if so thats good cheers

Great idea, nice video Alan.

And what many don't realise is the runout is different at almost every different clamping diameter.... this isn't set and forget.

Very interesting. Nice video sir. Thanks

From Ekatherineburg Russia this week Kit from up north

That works very well Alan

Early Rolls-Royce cars used spur gear differentials...Back when they made the 10 hp 2 cylinder cars, etc.

Very nice! I can find very little about spur gear differentials. why is barely used, anyone know? i would say it has some advantages compared to a usual ("pin-gear"?) differntial. For example could be potentially flatter.

hi Alan, I always use a guide when bending pipes, if a tight bend ,I will pack the pipe with kiln dried sand as well. Will be nice to see it running. not far off now!

You should have way more subscribers!

Hi. Is that your own design of that engine? Looks awesome.

That engine looks great. Your work is on another level. Very nice work sir

Very nice work Alan, it looks just smashing. Great to see the motor come together, cheers and thanks!

It's looking really good. Getting close now.

I also use the sand works every time. Very nice work on the engine

For bending brass or copper I anneal pipe make tight fit nylon plugs for each end pack pipe with salt or fine dry sand to stop pipe collapsing, bend freehand or use mandrel 👍

Allan do you have 3 phases power in your work shop ! Watch from Saint Petersburg Russia Kit from up north

Thank you very much for taking the time to make this video

The most important accessory for that machine is a wheel guard. These wheels are extremely dangerous.

That engine is coming along. Your work is on a good standard. Nice work sir

Glad you came out! I appreciate the creators work and diligence and it is nice to put a face with a name. Keep them coming.

Looks great! Clever workarounds.

Thankyou for nominating the inserts you used

Really enjoyed the build Allan. Appreciate your detailed descriptions and work around Cheers Jeff

Very well done

that thing looks really good Alan, reminds me of a supercharger from a vintage Bently or similar ,,,, cheers mate!!

THere's definitely a light at the end of the tunnel ! Thoroughly enjoying your build.

Nice work again Alan

It's looking really good Alan.

look really great Alan well done

Looking good! I cut Alu at 600 RPM with my slitting saw in order to leave a good finish.

I watched this another day and I just tested it on my mini 3inch rotary head, it works! I have been tapping the chuck with hammer for hours and it won’t true up until I saw this method. Many thanks!

Outstanding Effort Alan, getting very close now ! I'll pop over soon to see it in the flesh !

Nice. Haven't seen that done before.

You have given me many ideas for my bandsaw. Thank you.

well done Alan. I've never made a cam, I'm going to bookmark this just in case😁

Nice work Alan, I wish I had a dollar for every time I stressed over a part, only to find the solution was a lot simpler than I had imagined. Always nice to solve a dilemma and hope for a simple task to come around again, cheers!

Pat yourself on the back for that..well done

Well done Alan.

Great video Alan, I like your calm, analytical approach to problems. Thank you for sharing.

Great job Alan.
