Re: Adjusting AD951 jointer fence squareness
开云体育Hi Anil, I did not respond as I have a diff model. I had following thoughts based upon dual 51, may not be very useful. First, are you missing a bolt to set the fence stop. As for the pin and slot. Can you loosen the bolts holding the side (with slot) and move it a little before retightening to get you the 1/2 deg?

Re: Totally off topic - batteries question
开云体育I’m not able to add much value on the Felder stuff as I’m a beginner, but I have a little experience with Lead-acid to lithium having installed a Voltronix Lithium ion battery kit in a Polaris EV and owning several electric vehicles. I’ve also done some reading. What follows is my understanding and may be helpful for context. ? Lithium batteries have a much longer lifespan if carefully managed than lead acid. On the Voltronix Polaris kit, there are 16 large 3.3V cells tied in parallel to allow for a 48V high current (up to 600A) source. There is a dedicated BMS (Battery Management System) which has a wire harness which can ?independently monitor all the cells during charging and discharging. With Lithium ion, overcharging or fully discharging a cell is very damaging, and given the packs are independent batteries tied in series, the state of charge will vary somewhat from battery to battery. So the BMS monitors all and makes decisions about halting charging and discharge based on the most charged/discharged cell respectively. I assume it also has some capability to “rebalance” cells by bleeding off charge on a cell or cells to better level out the state of charge across all the cells of the system.? If you buy a large 12V lithium battery from a company like??then the battery will be composed of cells and include an internal BMS. If you plan to connect multiple of these batteries in series or parallel, then I’d talk to the battery company and ask about the specific application and their charger recommendations, because there are likely implications you may not understand. I hope this is a) accurate and b) helpful! ? Michael Branning On Feb 19, 2024, at 10:01?AM, imranindiana <imranindiana@...> wrote:

Re: Totally off topic - batteries question
开云体育Glen, I did not want to assume but I am pretty sure these batteries are in parallel. In ideal situation batteries should be same voltage. Since this is not happening in your case and assuming the batteries are good the wiring could be at fault. First, are there on/off switches for each battery? If so, make sure that the one for 95Ahr is working. Have you tried disconnecting 70Ahr battery to see if 95Ahr runs your system? If it does, check the wire that shorts the two batteries together. A bad connection on + or - post can prevent the 95Ahr battery to charge the 75Ahr battery and equalize voltage. Imran Malik On Feb 19, 2024, at 9:06?AM, John Hinman <jhinman1911@...> wrote:

Re: Totally off topic - batteries question
开云体育Hi Glen,It has been a while, to hear from you. The key question is, are these used in parallel? Like two, 12v batteries used in parallel in a 12V system or two 12V batteries used in series in a 24V system. Imran Malik On Feb 19, 2024, at 7:09?AM, glenhyrst <phil_moger@...> wrote:

Re: Totally off topic - batteries question
You should try to get in touch with Sandra Johnson sstraveler-Sandy on YouTube. She has changed the world of LTV owners switching to batteries vs plugging in. She has taught several Rv companies and CTM customs how to wire the batteries. Of course lithium has been the move from AGM batteries.

Re: Retro spiral cutter head?
开云体育
I'd only add that Tersa ( my favorite also ) is generally found on a higher end machine and benefits from a chipbreaker, pressure bar, and good hold downs similar to what is needed for a good straight knife machine.? A spiral is better on a lower end machine
as the head compensates for the lack of those items.? The chips are an issue as the Tersa needs better dust collection but the power needed for a spiral depends somewhat on it's design and the number of inserts.? Most high end planers are three phase and 7.5
hp so kind of irrelevant.? If i was buying a Hammer or 700 series I'd look at spiral.? A Format or Martin, I'd go Tersa.

Re: Retro spiral cutter head?
开云体育Hi Lucky, I have not used a spiral head but manufacturers claim that it requires less power. I assume it is due to the fact that the straight knife cuts the entire width at the same time but on spiral head, depending upon the geometry, very few carbide cutters are engaged at any given time.

Hi Phil,?
?Alex covered most of the advantages. Other advantages include the ability to swap out different alloy blades with different cutting geometries for different wood species. For instance, the Chrome and High Speed Steel knives have a 40 degree angle and are recommended for softwoods, whereas the M+ and Carbide knives have a 55 degree angle and are recommended for hardwoods and exotics. There are additional blades with different coatings and/or alloys.? ?In terms of noise, the Tersa head is supposed to be less noisy than traditional straight knife cutter blocks due to the 2mm projection of the knives, but not quite as quiet as segmented cutter blocks. -- Tom Gensmer Heritage Home Renewals, LLC Minneapolis, MN |
Re: Retro spiral cutter head?
开云体育Hi Phil,The link Tom included in his suggestion about tersa cutter blocks says it all. ?Tersa cutter blocks use full length straight knives like most of the older design planers and jointers. ?They just have a unique design that enables one to very quickly change out dull or damaged knives for new sharp knives. ?There is no need for specialty tools and there is no hassle with setting the knives. Other than that, I see no advantage to Tersa cutter blocks. Have a wonderful day, Alex B.
