Thanks for taking the time to give feedback Robin. Cliff

I must be so lucky. I bought a series 1 in 2008, it's been running for 13 years, and while I've had to make some electrical repairs and modifications, I have never done anything to it mechanically -- it's pretty well the way I took it out of the crate, and it's run for about 1 zillion hours.

Good to hear! Cliff

I sold my PCNC 770 a year ago and have been kicking myself ever since. I just bought a used 1100M so I'm back in the game! Catching up on all of your videos. Thanks for sharing!

[@Threadexpress]

Welcome back to the game! (And now you have more cast iron to enjoy). Cheers Cliff

@@Threadexpress And I need an ITTP to go along with it How do I order one?

great explanation and demonstrations of what's going on. Thank you.

[@Threadexpress]

Cheers! Cliff

[@peterlarsen7858]

Great description of that process. So looking forward to getting my 770m and setting it up with a level similar to yours. The very accurate level will make it difficult but that's all I have.

[@Threadexpress]

Thanks for that feedback Peter. Cheers Cliff

Try using non-stick BBQ grilling mat in roll form (70"x16") available from Amazon. It's an inexpensive source for glass reinforced teflon. Attach to table end of bellows and run back and up the Z column. It can easily be sewn into tented shape also. Digi-pas makes a digital level of high accuracy. The bluetooth version lets you lay on the ground and adjust leveling feet while digital level is up on equipment. Cheers.

Hi SH. Interesting idea for a cover! Can you put a link to the item - I have looked and not sure I can find the one you suggest. Thanks for introducing Digi-pas - looks like some of the higher end expensive models would do the job. Cheers Cliff

@@Threadexpress Hi Cliff, I see similar on Aliexpress and Bangood. Your local kitchen supply will sell smaller as oven liner (www.kitchenshop.co.nz/product/BBQ-liner-sheet.html). Cheers, Matt.

wood that gets wet exerts tremendous forces on whatever it's between. just a pin hole in an epoxied piece will demonstrate the explosive forces involved. Plywood might be a neat idea but I cannot imagine wood being stable for any amount of time.

[@Threadexpress]

Hi Jonathan. Thanks for raising that point, yes it probably is likely the plywood is wet in part, or at times - so thanks for the heads up. Cliff

[@automan1223]

@@Threadexpress I can see how using crushable plywood or a thin veneer of some kind achieve what you are trying to do. The key being that you would then want to measure a height of the area around the hold down bolt and then put a metal shim in as some kind of permanent solution. The problem being having a reliable way to measure the heights. on at least 2 of the corners.

[@kierangcollins]

Thanks for all the info there.

Hi Cliff, I'm curious what model of Girod lever-type indicator you've got? I had a look at their site and they've got quite a range of models. Similar to your comment that you'd like a level with about 0.001" per foot gradation for workshop use, what would you be after in a levered dial?

[@Threadexpress]

Hi Darran. Well I just had a look and it does not have a model number! It is a 0.01mm grad 0.8 mm revolution Girod- Tast with 6 rubies - but no model number! I also have a 0.002 mm lever indicator, but I find it is not practical - too quickly off the scale and so hardly ever use it. 99% of the time the 0.01mm grad is better to use. (or inch equivalent) And you can actually see 0.002mm movement anyway. Seems some folk assume finer must be better, but I disagree. (unless to are only doing high precision metrology tasks) . Cheers Cliff

[@BerndFelsche]

How does 0.1mm/m sound? www.leveldevelopments.com/products/engineers-level/engineers-levels/61r-0-1-100-engineers-level-100mm-long-sens-0-1mmm/ Most others are of the sensitivities you mentioned.

[@Threadexpress]

Hi Bernd - They look really good. That is close to 0.001" per foot. I would think it best to not buy too short, though, maybe minimum 200 mm long - they are not cheap. Good spotting! Cheers Cliff

[@chrismayhew3651]

I'm certainly no expert but I have a 0.05mm per Meter in the shape of the green square ones in the lower right of the screenshot at kzbin.info/www/bejne/Y4PKc2V9rp2or5o - that seems to work better overall than the 0.02mm per Meter I purchased for the very reasons you mention, at least from my experience in trying to get the twist out of my Tormach. When you have the Tormach stand with 4 feet you really do end up going round in circles very easily with the 0.02mm per Meter level. I've been thinking of changing to a 3 point mount by spanning the rear 2 feet mounting points with some box section and one foot in the middle and use 2 short lengths of the same size box section as spacers for the front feet. You would need to replace the studs with some longer ones to match of course. I'd be interested to know if anyone has tried doing this?

[@Threadexpress]

Hi Chris. Thanks for your thoughts here. Let us know if you try your span idea, how it goes. Cheers Cliff
