News and Order Updates
09/27/22 – We just received word that our custom lapping tools have shipped! We’ve decided to start lapping the OD of our spindles for two reasons; 1) complete control over the spindle diameter where the bearings are seated, 2) lapping makes that bearing area on the spindle even more round…and with shrink fit bearings, it keeps any tiny out of round areas of the spindle from misshaping the inner race of the bearing. We are new to OD lapping, so I will need to get a little practice in and discover the best way to set things up for lapping.
09/01/22 – The new website should be up and running sometime in October if all goes to plan. We will be switching webstore platforms with the new website release. You will likely get notices twice about your orders getting filled…one notice from our current webstore and one from the new webstore. The new webstore will have a link to the current webstore, but here’s a link to the current webstore just incase something doesn’t go as planned when releasing the upcoming new webstore… https://taig-sherline-mill-lathe.ecwid.com
For September and October, my time will be divided between doing parts runs, shipping orders and getting the new website up for a better customer experience. We may also switch over to using a mix of steel and aluminum for the motor mounts. This will make the mounts stronger with less bulk. The weight will be about the same. Some new parts will start to be shipped with a polished aluminum finish instead of anodized. This is for two reasons..1) it looks cool, and 2) in theory, it will reduce build time and cost. As you may have read, I do finally have someone helping me now. I’m hoping to get my new helper trained for a few specific tasks this month and that will help greatly.
5C Chuck Plate Adapters – We’re finally getting around to having them made. We can’t make those inhouse, so we’ll have an outside supplier make them. The two sizes will be for 5″ and 6″ chucks and will likely be offered in finished and semi-finished versions. I don’t have a cost yet or ship date. As soon as I know that information, I’ll put it on this update page and in the store. The first batch will be small because I’m now pretty careful not to place large orders for new products…not until I know for sure the supplier can make them correctly.
Some new parts that you’ll see on the website soon. As we’ve started to make as many parts as possible in-house, we been doing a lot more cutting. A lot of the cuts are slotting and deep boring using 20mm screw-in insert cutters. The big challenge is chip removal…especially with hot aluminum turning gummy. So, I ended up designing and 3D printed fans that slide on to end mills, indexable cutters and BT30 tooling. They ended up working amazingly well at blowing chips out and keeping the part cleaner when done! We have a very good, very accurate 3D printer making these now. They are available in fractional sizes and metric sizes. Other available versions mount to ER nuts, the shafts of index cutters and blanks that you can drill to size. The version that mounts to a BT30 tool holder’s flange area really blows a ton of air…it’s my favorite.
Over time, we’ve had plenty of people ask about attaching an encoder to our headstocks for indexing…which is something we too want to use. You will soon be able to order 3D printed timing pulleys that will fit the 5C, BT30 and all other headstocks that have a 30mm ID (R8, ISO20, ER etc.). For the encoder side, you will have both fractional and metric bore options. We will have a 3D printed encoder mount available at some point, but I just don’t have the time to make that part just right now.
Our website server went down and we lost a portion of our website formatting and data. The ecommerce store was unaffected because it runs on a different server. So, the website will look a little weird for several weeks while I rebuild it and also still work in the shop to make parts. For the next few weeks starting August 22, I’ll be spending most of my shop time doing production runs on parts. This will also include modifying some parts from a supplier. The headstock bearing openings need to be opened up a little bit so they don’t compress the bearings too much. For the R8 customers, pilot hole in the spindle also needs to be opened up a little (that one inch or so section at the top of the R8 tool is the pilot). We tried a few ways to open that up and best way seems to be lapping it. That way it’s not taking off too much material and actually makes it more round. We ordered a custom blind helical internal lap just for the R8. The lap company said 3 to 4 weeks and we ordered it 08/08.
New motor mounts should be available on 7/28. They will look different from the mounts shown on the website. They are now made in the USA using stock that’s more readily available. We likely won’t update the images on the website until the new website goes up.
All orders with the optional secondary grind operation – The grinding shop we use received the broken parts replacements a few weeks ago to repair their machine. It’s my understanding that they will complete our parts about half way through August. Again, this is only for those who ordered the optional secondary grind operation.
I had a streak of migraines for several weeks recently. So keep that in mind as I continue to catch up on orders.
June 2022 –

- We are steadly shipping orders and slowly catching up. Right now all ABEC9 hybrid steel/ceramic bearings are about 3 to 4 weeks out from order date. All BT30 ER32 tooling is about 4 to 5 weeks out.
- In the downloads section, there are new documents for motors and headstocks. Also a video on setting the torque parameter for your 750w or 1200w motor driver.
- Within the next two weeks-ish, if all goes to plan, the website will be changing. The new website will have a menu item that takes you to the current ecommerce store for orders placed before the website change. We’ve been needing to update the website for awhile.
- I will have limited availability from April 2 to April 10th.
- I’ll be posting a video here and on our youtube channel showing a fun little demo using the Taig mill and BT30 headstock with 1200w motor…we’ll be cutting at 39 IPM using a 50mm face mill and 1/2″ end mill.
[text_block style=”style_1.png” align=”left”]February 8, 2022 – We are catching up on orders, slowly but surely. We have orders with motors going out and are waiting on more to be made for us. New headstock casings have also arrived. We couldn’t use quite a few headstock casings from the last batch, they were out of spec…but, the supplier did replace them..they weren’t fast about it, but I’m very pleased that they replaced them. We hope to be fully caught up on headstock orders in the next few months. Because of the chip shortage, we will send motors out as we get them in. Some headstocks will be sent out by themselves and the motor will be sent when get them them in (that is, if you ordered both a headstock and motor). As of now, any new ER25 orders will be have to wait until we get a new batch of ER25 spindles in…we don’t have a date for those just yet. Also, as we update orders with a tracking number, we may not be able to get the package dropped off the same day that we provide the tracking number.
Other notes… We are migrating our website to a new server, so hopefully there won’t be much down time. Just know that the website might be on and off while they do the migration. We’ve had a really hard time updating our website, so we’re upgrading servers to solve the issue (well, that’s what our service provide says anyway).
For new products… This spring after we’re caught up on headstock orders, we will have the adapter kit for using the BT-30 headstocks on Grizzly G0704 and Precission Matthews PM-25 mills. Along with that, the adapter to locate our current motors behind the headstock for those mills will be available. The high frequency 18,000RPM 4 Pole motor probably won’t be until late summer. The CAT40 might be this summer, but everything seems to go more slowly than I like..so, we shall see.
Website Changes… I’ve added a download page for motor/driver documentation and will also be adding headstock info shortly. I’ll also be adding a video section with instructional videos, demos and other cool videos I’ve found by others.[/text_block]
[text_block style=”style_1.png” align=”left”]October 29. 2021 – Good news! We got a bunch of parts in recently. Enough headstock parts that it looks like we’ll catch up on all orders to date for those parts. It also looks like we’ll be getting motors midway through next month. I’m not sure how many motors our supplier is allotting us…but we’ll take anything at this point. For domestic orders, if you have a headstock with motor ordered and we don’t have the motor yet, we will start doing split fulfillment. In other words, we’re going to send you the headstock with any other in stock parts and if you have a motor coming to you, we’ll send that as soon as we get it. The past few years have been challenging for us and many others. I again want to thank all of you for your patience.
As a general company news update… We’ve also purchased a new CNC mill to build more of the parts in house. The goal is to prevent out of stock issues on milled parts until our outside suppliers can get us parts, if that situation comes up. Turning and grinding spindles will still all be done by our outside suppliers. Secondary ID grinding will be done inhouse.
September 9, 2021 – We just got a shipment of aluminum parts and one steel part in. This shipment included: motor mounts, HD headstocks for ER, R8 and ISO20 models, R8 drawbars. The redesigned TaigTurn and Micro lathe adapters, new R8 low profile spindle arbors and ISO20 drawbars will be here in about 2 weeks. For us to send out more 5C headstocks, we will need to get the new headstock casing shipment in. They haven’t given me a ship date, but it should be just a matter of weeks. It’s the same for the new BT30 drawbars.
What we know there will be a delay on is the motor controllers. The chip shortage has affected us just like so many others. I haven’t been given a ship date on those because I don’t think the manufacture knows a potential ship date. I get the feeling that the bigger corporate players are sweeping up all the chip resources before the smaller guys can get chips. The reason I say that is because some suppliers have had chip manufactures back out of orders just to cater to their bigger customers. Some of you guys have told me you’re in the same boat with your business as well.
For those asking about the CAT40 for the Grizzly, Precision Matthews and other BF models…I’m guessing, and this is strictly a guess, that we will have them designed and ordered in the spring with a Summer delivery. We may however, offer a BT30 headstock adapter sooner than that. We don’t really want to get started on too much new stuff until we’re finally in a position to carry inventory for our current line up. Hopefully that makes sense.
I have spoken casually to some about an ID/OD grinder possibility. This would be setup that can be used with a lathe, mill or custom setup. This will likely become available this winter because it would be using existing part designs. That means the same headstock build time frames apply. It’s more of a tooling and pulley package to use existing headstock models as grinders. The BT30 will likely be the “go to” model for this. If you’re thinking about grinding, start thinking about your dust extraction strategy. You don’t want that stuff getting into any friction surfaces…it can and will ruin ballscrews and bearings if it’s not controlled. For some reason, grinding dust is pretty sneaky and gets into the oddest places.
August 13, 2021 – I’ll be available until next week to respond to emails and so on. Early this week, my wife was unexpectedly hospitalized. It appears she’ll be fine, but that pretty much put the whole week on hold for us. It’s one of those things that makes the week a blur and loose track of what day it is. Anyway, thanks.
Almost forgot, I’m waiting on an updated production schedule for the aluminum parts. That will give us a better idea of what will come when. Keep in mind, that’s the suppliers best guess as to time.
July 20, 2021 – We are still currently shipping BT30 and 5C headstocks. Those with motor orders…we are out of motor mounts and they should, in theory, be here in about 4ish weeks. Those with ISO-20 and R8 low profile headstocks, we are out of headstock casings and those also should be here in 4ish weeks. I can also foresee us running out of BT30 and 5C headstock casings over the next few weeks. The new casings will be in with that 4ish week order. We were shooting for June on the parts I just mentioned, but we got pushed back. I suspect from much bigger customers than us getting priority. For motors, we are sending out everything we currently have and more will be coming. I don’t have a date for the motors yet. The motors are custom wound for us and the drivers are also modified from what from what they normally produce. So, they are just an on the shelf product.
May 25, 2021 – Because this page was acting strange and wouldn’t update correctly, I’ve started it over fresh. Anyway, we have a long awaited shipment of 5C spindles that are schedule to arrive late next week. This is our first batch using our changed manufacturing process. We should have motor mounts and the headstock casings for R8, ISO20, ER here late June.[/text_block]
